您可以通过编程方式执行此操作:

public class ActivityName extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // remove title
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main);
    }
}

或者您可以通过 AndroidManifest.xml 文件执行此操作:

<activity android:name=".ActivityName"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen"/>

编辑:

如果您使用的是 AppCompatActivity,则需要添加一个新主题:

<style name="Theme.AppCompat.Light.NoActionBar.FullScreen" parent="@style/Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

然后使用它。

<activity android:name=".ActivityName"
    android:label="@string/app_name"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar.FullScreen"/>

由于:
https://stackoverflow.com/a/25365193/1646479

You can do it programmatically :

public class ActivityName extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // remove title
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main);
    }
}

Or you can do it via your AndroidManifest.xml file:

<activity android:name=".ActivityName"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen"/>

Edit:

If you are using AppCompatActivity then you need to add a new theme:

<style name="Theme.AppCompat.Light.NoActionBar.FullScreen" parent="@style/Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

and then use it.

<activity android:name=".ActivityName"
    android:label="@string/app_name"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar.FullScreen"/>

KitKat 中提供了一种名为沉浸式全屏模式的技术
沉浸式全屏模式演示

示例

There's a technique called Immersive Full-Screen Mode available in KitKat.

如果您不想使用主题 @android:style/Theme.NoTitleBar.Fullscreen 因为您已经在使用自己的主题,则可以使用 android:windowFullscreen >。

在 AndroidManifest.xml 中:

<activity
  android:name=".ui.activity.MyActivity"
  android:theme="@style/MyTheme">
</activity>

在 styles.xml 中:

<style name="MyTheme"  parent="your parent theme">
  <item name="android:windowNoTitle">true</item>
  <item name="android:windowFullscreen">true</item> 
</style>

If you don't want to use the theme @android:style/Theme.NoTitleBar.Fullscreen because you are already using a theme of you own, you can use android:windowFullscreen.

In AndroidManifest.xml:

<activity
  android:name=".ui.activity.MyActivity"
  android:theme="@style/MyTheme">
</activity>

In styles.xml:

<style name="MyTheme"  parent="your parent theme">
  <item name="android:windowNoTitle">true</item>
  <item name="android:windowFullscreen">true</item> 
</style>

AndroidManifest.xml 文件中:

<activity
    android:name=".Launch"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen" > <!-- This line is important -->

    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>  

或在 Java 代码中:

protected void onCreate(Bundle savedInstanceState){
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}

In AndroidManifest.xml file:

<activity
    android:name=".Launch"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen" > <!-- This line is important -->

    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>  

Or in Java code:

protected void onCreate(Bundle savedInstanceState){
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}

对于 AndroidX

1. 透明状态栏

    window?.decorView?.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN)
    window.statusBarColor = Color.TRANSPARENT

在此处输入图像描述

2. 透明状态栏和透明状态栏底部导航栏

    window.setFlags(
        WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
        WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
    );

enter图片说明此处

3. 隐藏状态栏

API 30+ 推荐的兼容解决方案(包括向后兼容性)

  val windowInsetsController =
      WindowCompat.getInsetsController(window, window.decorView) ?: return
  windowInsetsController.systemBarsBehavior =
      WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
  windowInsetsController.hide(WindowInsetsCompat.Type.statusBars())

https://developer.android.com/training/system-ui/immersive

在此处输入图像描述

4. 隐藏状态栏和状态栏底部导航栏

API 级别 30:

SystemUiVisibility 标志已弃用。请改用 WindowInsetsController。

与3.相同,只需使用 WindowInsetsCompat.Type.systemBars()

    val actionBar: ActionBar? = supportActionBar
        if (actionBar != null) actionBar.hide()

    val windowInsetsController =
        WindowCompat.getInsetsController(window, window.decorView) ?: return
    windowInsetsController.systemBarsBehavior =
        WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
    windowInsetsController.hide(WindowInsetsCompat.Type.systemBars())

https://developer.android.com/training/system-ui/immersive

< img src="https://i.sstatic.net/PcmLFl.png" alt="在此处输入图像描述">

将此代码放在哪里?

   override fun onCreate(savedInstanceState: Bundle?) {

        /*  Put above code here ..... */
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_slider)
   }

注意

  • 我在 Pixel 3A 模拟器中检查了这段代码
  • 也许自定义 android 操作系统不支持
  • 设置样式

For AndroidX

1. Transparent Statusbar

    window?.decorView?.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN)
    window.statusBarColor = Color.TRANSPARENT

enter image description here

2. Transparent Statusbar & Bottomnav bar

    window.setFlags(
        WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
        WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
    );

enter image description here

3. Hide Statusbar

Recommended Compat solution for API 30+ (inclusive backwards compatibility)

  val windowInsetsController =
      WindowCompat.getInsetsController(window, window.decorView) ?: return
  windowInsetsController.systemBarsBehavior =
      WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
  windowInsetsController.hide(WindowInsetsCompat.Type.statusBars())

https://developer.android.com/training/system-ui/immersive

enter image description here

4. Hide Statubar & Bottomnav bar

API level 30:

SystemUiVisibility flags are deprecated. Use WindowInsetsController instead.

Same as 3., just use WindowInsetsCompat.Type.systemBars()

    val actionBar: ActionBar? = supportActionBar
        if (actionBar != null) actionBar.hide()

    val windowInsetsController =
        WindowCompat.getInsetsController(window, window.decorView) ?: return
    windowInsetsController.systemBarsBehavior =
        WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
    windowInsetsController.hide(WindowInsetsCompat.Type.systemBars())

https://developer.android.com/training/system-ui/immersive

enter image description here

Where to put this code ?

   override fun onCreate(savedInstanceState: Bundle?) {

        /*  Put above code here ..... */
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_slider)
   }

Note

  • I checked this code in Pixel 3A emulator
  • Maybe customise android OS not support
  • set style <style name="Theme.FullScreen" parent="Theme.MaterialComponents.DayNight.NoActionBar">

如果您使用 AppCompat 和 ActionBarActivity,请使用此

getSupportActionBar().hide();

If your using AppCompat and ActionBarActivity, then use this

getSupportActionBar().hide();

征﹌骨岁月お 2024-09-09 07:16:17

请注意,

requestWindowFeature(Window.FEATURE_NO_TITLE);

如果您使用任何方法设置操作栏,如下所示:

getSupportActionBar().setHomeButtonEnabled(true);

它将导致空指针异常。

Be careful with

requestWindowFeature(Window.FEATURE_NO_TITLE);

If you are using any method to set the action bar as the follow:

getSupportActionBar().setHomeButtonEnabled(true);

It will cause a null pointer exception.

使用 style.xml 中的 appcompat 尝试此操作。它为所有平台提供支持。

<!-- Application theme. -->
<style name="AppTheme.FullScreen" parent="AppTheme">
    <item name="android:windowFullscreen">true</item>
</style>


<!-- Application theme. -->
<style name="AppTheme" parent="@style/Theme.AppCompat.Light.NoActionBar" />

Try this with appcompat from style.xml. It provides support for all platforms.

<!-- Application theme. -->
<style name="AppTheme.FullScreen" parent="AppTheme">
    <item name="android:windowFullscreen">true</item>
</style>


<!-- Application theme. -->
<style name="AppTheme" parent="@style/Theme.AppCompat.Light.NoActionBar" />

使用Android Studio(当前版本是2.2.2)可以非常轻松地添加全屏活动。

查看步骤:

  1. 右键单击您的java主包>选择“新建”>选择“活动”>然后,单击“全屏活动”。

第一步

  1. 自定义活动(“活动名称”、“布局名称”等)并单击“完成”。

第二步

完成!

现在您已经轻松制作了一个全屏活动(请参阅 java 类和活动布局以了解其工作原理)!

Using Android Studio (current version is 2.2.2 at moment) is very easy to add a fullscreen activity.

See the steps:

  1. Right click on your java main package > Select “New” > Select “Activity” > Then, click on “Fullscreen Activity”.

Step one

  1. Customize the activity (“Activity Name”, “Layout Name” and so on) and click “finish”.

Step two

Done!

Now you have a fullscreen activity made easily (see the java class and the activity layout to know how the things works)!

原野 2024-09-09 07:16:17

首先,您必须使用“NoActionBar”设置应用程序主题,如下所示,

<!-- Application theme. -->
<style name="AppTheme" parent="@style/Theme.AppCompat.Light.NoActionBar" />

然后在全屏活动中添加这些行。

public class MainActiviy extends AppCompatActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                                  WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main);
    }
}

它将隐藏全屏活动中的操作栏/工具栏以及状态栏

First you must to set you app theme with "NoActionBar" like below

<!-- Application theme. -->
<style name="AppTheme" parent="@style/Theme.AppCompat.Light.NoActionBar" />

Then add these lines in your fullscreen activity.

public class MainActiviy extends AppCompatActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                                  WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main);
    }
}

It will hide actionbar/toolbar and also statusbar in your fullscreen activity

I. 您的主应用程序主题是Theme.AppCompat.Light.DarkActionBar

用于隐藏 ActionBar / StatusBar
style.xml

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    ...
</style>

<style name="FullScreenTheme" parent="AppTheme">
    <!--this property will help hide the ActionBar-->
    <item name="windowNoTitle">true</item>
    <!--currently, I don't know why we need this property since use windowNoTitle only already help hide actionbar. I use it because it is used inside Theme.AppCompat.Light.NoActionBar (you can check Theme.AppCompat.Light.NoActionBar code). I think there are some missing case that I don't know-->
    <item name="windowActionBar">false</item>
    <!--this property is used for hiding StatusBar-->
    <item name="android:windowFullscreen">true</item>

</style>

<style name="FullScreenTheme" parent="AppTheme">
    <!--don't need any config for hide ActionBar because our apptheme is NoActionBar-->
    <!--this property is use for hide StatusBar-->
    <item name="android:windowFullscreen">true</item> // 
</style>

隐藏系统导航栏

类似Theme.AppCompat.Light.DarkActionBar

演示

AndroidManifest.xml

<activity ...
          android:theme="@style/FullScreenTheme"
    >
</activity>

I. Your main app the theme is Theme.AppCompat.Light.DarkActionBar

For hide ActionBar / StatusBar

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    ...
</style>

<style name="FullScreenTheme" parent="AppTheme">
    <!--this property will help hide the ActionBar-->
    <item name="windowNoTitle">true</item>
    <!--currently, I don't know why we need this property since use windowNoTitle only already help hide actionbar. I use it because it is used inside Theme.AppCompat.Light.NoActionBar (you can check Theme.AppCompat.Light.NoActionBar code). I think there are some missing case that I don't know-->
    <item name="windowActionBar">false</item>
    <!--this property is used for hiding StatusBar-->
    <item name="android:windowFullscreen">true</item>
</style>

To hide the system navigation bar

public class MainActivity extends AppCompatActivity {

    protected void onCreate(Bundle savedInstanceState) {
        getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
        setContentView(R.layout.activity_main)
        ...
    }
 }

II. Your main app theme is Theme.AppCompat.Light.NoActionBar

For hide ActionBar / StatusBar
style.xml

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    ...
</style>

<style name="FullScreenTheme" parent="AppTheme">
    <!--don't need any config for hide ActionBar because our apptheme is NoActionBar-->
    <!--this property is use for hide StatusBar-->

感谢您的回答@Cristian 我收到错误

android.util.AndroidRuntimeException:必须调用 requestFeature()
添加内容之前

我使用以下方法解决了这个问题

@Override
protected void onCreate(Bundle savedInstanceState) {

    requestWindowFeature(Window.FEATURE_NO_TITLE);

    super.onCreate(savedInstanceState);

    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.activity_login);

    -----

}

thanks for answer @Cristian i was getting error

android.util.AndroidRuntimeException: requestFeature() must be called
before adding content

i solved this using

@Override
protected void onCreate(Bundle savedInstanceState) {

    requestWindowFeature(Window.FEATURE_NO_TITLE);

    super.onCreate(savedInstanceState);

    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

在 styles.xml 中添加此

<item name="android:windowFullscreen">true</item>

示例 -

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="android:windowFullscreen">true</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

并使用以下代码

android:theme="@style/AppTheme"

示例更改 AndroidManifest 文件 -

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:theme="@style/AppTheme"
    android:supportsRtl="true">

Add this in styles.xml

<item name="android:windowFullscreen">true</item>

Example -

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="android:windowFullscreen">true</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

And change AndroidManifest file with bellow code

android:theme="@style/AppTheme"

Example -

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"

            View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    //| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                    //| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                    | View.SYSTEM_UI_FLAG_IMMERSIVE);
}

然后,您重置为默认状态:

在此处输入图像描述

public static void showSystemUI(Activity activity) {
    View decorView = activity.getWindow().getDecorView();
    decorView.setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}

您可以在 onCreate 中调用上述函数:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.course_activity);
    UiUtils.hideSystemUI(this);
}

Here is an example code. You can turn on/off flags to hide/show specific parts.

enter image description here

public static void hideSystemUI(Activity activity) {
    View decorView = activity.getWindow().getDecorView();
    decorView.setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    //| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                    //| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                    | View.SYSTEM_UI_FLAG_IMMERSIVE);
}

Then, you reset to the default state:

enter image description here

public static void showSystemUI(Activity activity) {
    View decorView = activity.getWindow().getDecorView();
    decorView.setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}

You can call the above functions from your onCreate:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.course_activity);
    UiUtils.hideSystemUI(this);
}

    window?.also {
        WindowCompat.setDecorFitsSystemWindows(it, !isFullScreen)
        WindowCompat.getInsetsController(it, it.decorView).apply {
            systemBarsBehavior =
                if (isFullScreen)
                    WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
                else
                    WindowInsetsControllerCompat.BEHAVIOR_SHOW_BARS_BY_TOUCH
            if (isFullScreen)
                hide(WindowInsetsCompat.Type.systemBars())
            else
                show(WindowInsetsCompat.Type.systemBars())
        }
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {

                    WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES
                else
                    WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_DEFAULT
        }
    }
}

just call this fun :

private fun changeScreenSystemUiController(isFullScreen: Boolean) {
    window?.also {
        WindowCompat.setDecorFitsSystemWindows(it, !isFullScreen)
        WindowCompat.getInsetsController(it, it.decorView).apply {
            systemBarsBehavior =

                    WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
                else
                    WindowInsetsControllerCompat.BEHAVIOR_SHOW_BARS_BY_TOUCH
            if (isFullScreen)
                hide(WindowInsetsCompat.Type.systemBars())
            else

我想使用我自己的主题而不是使用@android:style/Theme.NoTitleBar.Fullscreen。但它并不像这里的一些帖子提到的那样工作,所以我做了一些调整来解决这个问题。

在 AndroidManifest.xml 中:

<activity
    android:name=".ui.activity.MyActivity"
    android:theme="@style/MyTheme">
</activity>

在 styles.xml 中:

<style name="MyTheme">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
</style>

注意:在我的例子中,我必须使用 name="windowActionBar" 而不是 name="android:windowActionBar" 才能工作适当地。所以我只是使用两者来确保以后需要移植到新的 Android 版本。

I wanted to use my own theme instead of using @android:style/Theme.NoTitleBar.Fullscreen. But it wasn't working as some post on here had mentioned, so I did some tweaking to figure it out.

In AndroidManifest.xml:

<activity
    android:name=".ui.activity.MyActivity"
    android:theme="@style/MyTheme">
</activity>

In styles.xml:

<style name="MyTheme">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
</style>

Note: in my case I had to use name="windowActionBar" instead of name="android:windowActionBar" before it worked properly. So I just used both to make sure in the case I need to port to a new Android version later.

一念一轮回 2024-09-09 07:16:17

要使您的活动全屏显示,请执行以下操作:

    // add following lines before setContentView
    // to hide toolbar
                if(getSupportActionBar()!=null)
                    getSupportActionBar().hide();
    //to hide status bar
                getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);

这将隐藏工具栏和状态栏。

但在某些情况下,您可能希望显示具有透明背景的状态栏,在这种情况下,请执行以下操作:

// add following lines before setContentView
// to hide toolbar
if(getSupportActionBar()!=null)
   getSupportActionBar().hide();
// to make status bar transparent
getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

其他一些替代方法来隐藏工具栏而不是
getSupportActionBar().hide()

  1. 通过更改应用主题的父级来删除工具栏:

  1. 如果您只想从一个 Activity 中删除工具栏,请转到清单,在 Activity 标签下添加以下内容: android:theme="@style/Theme.AppCompat.Light.NoActionBar"

For kotlin爱好者,为什么不使用扩展函数:

第一种情况:

fun AppCompatActivity.makeItFullScreenStatusBarVisible(){
    supportActionBar?.hide()
    window.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
}

setContentView 之前调用:

makeItFullScreenStatusBarVisible()

对于第二种情况:

fun AppCompatActivity.makeItFullScreenStatusBarHidden(){
    supportActionBar?.hide()
    window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN)
}

setContentView 之前调用:

makeItFullScreenStatusBarHidden()

To make your activity full screen do this:

    // add following lines before setContentView
    // to hide toolbar
                if(getSupportActionBar()!=null)
                    getSupportActionBar().hide();
    //to hide status bar
                getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);

This will hide the toolbar and status bar.

But In some case, you may want to show status bar with a transparent background, in that case, do this:

// add following lines before setContentView
// to hide toolbar
if(getSupportActionBar()!=null)
   getSupportActionBar().hide();
// to make status bar transparent
getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

Some other alternate to hide toolbar instead of
getSupportActionBar().hide():

  1. Remove toolbar by changing the app theme's parent:

<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">

  1. If you want to remove the toolbar from only one activity then go to manifest, under activity tag add this: android:theme="@style/Theme.AppCompat.Light.NoActionBar"

For kotlin lovers, why not use extension functions:

For first case:

fun AppCompatActivity.makeItFullScreenStatusBarVisible(){
    supportActionBar?.hide()
    window.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
}

And call this before setContentView:

makeItFullScreenStatusBarVisible()

For Second One:

fun AppCompatActivity.makeItFullScreenStatusBarHidden(){
    supportActionBar?.hide()
    window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN)
}

And call it before setContentView:

makeItFullScreenStatusBarHidden()

提示:使用 getWindow().setLayout() 可能会搞乱您的全屏显示!请注意此方法的文档说:

设置窗口的宽度和高度布局参数...
您可以将它们更改为...绝对值以创建非全屏的窗口。

http://developer.android.com/参考/android/view/Window.html#setLayout%28int,%20int%29

出于我的目的,我发现我必须使用带有绝对参数的 setLayout 来正确调整全屏窗口的大小。大多数时候,这工作得很好。它由 onConfigurationChanged() 事件调用。然而,有一个小问题。如果用户退出应用程序,更改方向,然后重新输入,则会导致触发包含 setLayout() 的代码。在此重新进入时间窗口期间,我的状态栏(被清单隐藏)将重新出现,但在任何其他时间 setLayout() 都不会导致这种情况!解决方案是在具有硬值的调用之后添加一个额外的 setLayout() 调用,如下所示:

       public static void setSize( final int width, final int height ){
//DO SOME OTHER STUFF...
            instance_.getWindow().setLayout( width, height );
            // Prevent status bar re-appearance
            Handler delay = new Handler();
            delay.postDelayed( new Runnable(){ public void run() {
                instance_.getWindow().setLayout(
                    WindowManager.LayoutParams.FILL_PARENT,
                    WindowManager.LayoutParams.FILL_PARENT );
            }}, FILL_PARENT_ON_RESIZE_DELAY_MILLIS );
        }

然后窗口正确地重新调整大小,并且无论触发此事件的事件如何,状态栏都不会重新出现。

TIP: Using getWindow().setLayout() can screw up your full screen display! Note the documentation for this method says:

Set the width and height layout parameters of the window...
you can change them to ... an absolute value to make a window that is not full-screen.

http://developer.android.com/reference/android/view/Window.html#setLayout%28int,%20int%29

For my purposes, I found that I had to use setLayout with absolute parameters to resize my full screen window correctly. Most of the time, this worked fine. It was called by an onConfigurationChanged() event. There was a hiccup, however. If the user exited the app, changed the orientation, and reentered, it would lead to firing off my code which included setLayout(). During this re-entry time window, my status bar (which was hidden by the manifest) would be made to re-appear, but at any other time setLayout() would not cause this! The solution was to add an additional setLayout() call after the one with the hard values like so:

       public static void setSize( final int width, final int height ){
//DO SOME OTHER STUFF...
            instance_.getWindow().setLayout( width, height );
            // Prevent status bar re-appearance
            Handler delay = new Handler();
            delay.postDelayed( new Runnable(){ public void run() {
                instance_.getWindow().setLayout(
                    WindowManager.LayoutParams.FILL_PARENT,
                    WindowManager.LayoutParams.FILL_PARENT );
            }}, FILL_PARENT_ON_RESIZE_DELAY_MILLIS );
        }

The window then correctly re-sized, and the status bar did not re-appear regardless of the event which triggered this.

这对我有用。

if (Build.VERSION.SDK_INT < 16) {
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
    } else {
        View decorView = getWindow().getDecorView();
        int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
        decorView.setSystemUiVisibility(uiOptions);
    }

It worked for me.

if (Build.VERSION.SDK_INT < 16) {
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
    } else {
        View decorView = getWindow().getDecorView();
        int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
        decorView.setSystemUiVisibility(uiOptions);
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_login)
        window.decorView.systemUiVisibility =
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE or
                View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or
                View.SYSTEM_UI_FLAG_FULLSCREEN

    }
}

沉浸模式

沉浸模式适用于用户将与屏幕进行大量交互的应用。例如游戏、查看图库中的图像或阅读分页内容,例如书籍或演示文稿中的幻灯片。为此,只需添加以下几行:

View.SYSTEM_UI_FLAG_HIDE_NAVIGATION or
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION

粘性沉浸式

在常规沉浸式模式中,每当用户从边缘滑动时,系统都会显示系统栏 - 您的应用程序甚至不会意识到该手势发生了。因此,如果用户实际上可能需要从屏幕边缘滑动作为主要应用程序体验的一部分(例如在玩需要大量滑动的游戏或使用绘图应用程序时),您应该启用“粘性”沉浸式模式。

View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY

详细信息:启用全屏模式

有关 键盘,有时会出现键盘出现时状态栏也显示的情况。在这种情况下,我通常将其添加到我的样式 xml

styles.xml

<style name="FullScreen" parent="AppTheme">
    <item name="android:windowFullscreen">true</item>
</style>

中,并将这一行添加到我的清单中

<activity
        android:name=".ui.login.LoginActivity"
        android:label="@string/title_activity_login"
        android:theme="@style/FullScreen">

With kotlin this is the way I did:

class LoginActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_login)
        window.decorView.systemUiVisibility =
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE or
                View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or
                View.SYSTEM_UI_FLAG_FULLSCREEN

    }
}

Immersive Mode

The immersive mode is intended for apps in which the user will be heavily interacting with the screen. Examples are games, viewing images in a gallery, or reading paginated content, like a book or slides in a presentation. For this, just add this lines:

View.SYSTEM_UI_FLAG_HIDE_NAVIGATION or
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION

Sticky immersive

In the regular immersive mode, any time a user swipes from an edge, the system takes care of revealing the system bars—your app won't even be aware that the gesture occurred. So if the user might actually need to swipe from the edge of the screen as part of the primary app experience—such as when playing a game that requires lots of swiping or using a drawing app—you should instead enable the "sticky" immersive mode.

View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY

For more information: Enable fullscreen mode

In case your using the keyboard, sometimes happens that StatusBar shows when keyboard shows up. In that case I usually add this to my style xml

styles.xml

<style name="FullScreen" parent="AppTheme">
    <item name="android:windowFullscreen">true</item>
</style>

And also this line to my manifest

<activity
        android:name=".ui.login.LoginActivity"
        android:label="@string/title_activity_login"
        android:theme="@style/FullScreen">

只需将此代码粘贴到 onCreate() 方法中

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

Just paste this code into onCreate() method

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

在 onCreate() 中的 setContentView 之后使用此方法,并通过 getWindow() 传递 Window 对象。

    public void makeActivityFullScreen(Window window){
    View decorView = window.getDecorView();
    //        int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
       window.getAttributes().layoutInDisplayCutoutMode = WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES;
    }
    decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE
            | View.SYSTEM_UI_FLAG_FULLSCREEN
            | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
    );
}

此代码也适用于凹口屏幕。要检查刘海屏全屏,您需要 Android P,但如果您有刘海屏手机,请转到设置-->显示设置-->应用程序显示比例-->选择您的应用程序 - --> 将有两个安全选项:显示和全屏,请选择全屏并运行应用程序,您也可以在刘海中看到全屏无需 Android Pie

Use this method after setContentView in onCreate() and pass the Window object by getWindow().

    public void makeActivityFullScreen(Window window){
    View decorView = window.getDecorView();
    //        int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
       window.getAttributes().layoutInDisplayCutoutMode = WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES;
    }
    decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE
            | View.SYSTEM_UI_FLAG_FULLSCREEN
            | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
    );
}

This code will work for notch screen also. To check the notch fullscreen you require android P but if You have a notch display phone then go to setting-->Display setting -->app display ratio --->select your app --->there will be two options safe are display and full screen , please select the full screen and run the app, you can see the fullscreen in notch also without having android Pie

输入图片此处描述

getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS); if (getSupportActionBar() != null){ getSupportActionBar().hide(); }

enter image description here

getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS); if (getSupportActionBar() != null){ getSupportActionBar().hide(); }
