TabWidget白色前景色?

发布于 2024-08-26 21:42:56 字数 163 浏览 10 评论 0原文

我不知道我做了什么,但有一段时间我的 TabWidget 有白色选项卡,看起来非常漂亮。我从来没有在我的项目中设置主题或背景/前景色。下次我编译它时,它又恢复为灰色选项卡。我的应用程序使用默认的深色主题。即使我将应用程序主题设置为浅色,选项卡仍然是灰色的。很明显,是其他东西改变了标签的颜色。有人知道该怎么做吗?

I don't know what I did but for a period of time my TabWidget had white colored tabs which looked really nice. I never set a theme or background/foreground color in my project at all. The next time I compiled it it reverted back to the gray tabs. My application is using the default dark theme. Even if I set the application theme to light, the tabs are still gray. So obviously it was something else that changed the tabs' color. Anyone know how to do this?

由于 Android 1.6 的浅色主题中的错误(选项卡指示器文本为白色),我遇到了问题。我能够按如下方式覆盖默认主题:

  1. 我创建了一个从默认主题继承的自定义主题:

styles.xml

<style name="MyTheme" parent="@android:style/Theme.Light">
    <item name="android:tabWidgetStyle">@style/LightTabWidget</item>
</style>

<style name="LightTabWidget" parent="@android:style/Widget.TabWidget">
    <!-- set textColor to red, so you can verify that it applied. -->
    <item name="android:textColor">#f00</item>
</style>

然后我只需通过添加android将该主题应用到我的应用程序: theme="@style/MyTheme" 到我的 AndroidManifest.xml 元素。

I was having a problem due to a bug in Android 1.6's light theme (tab indicator text is white). I was able to override the default theme as follows:

  1. I created a custom theme that inherited from the default theme:

styles.xml:

<style name="MyTheme" parent="@android:style/Theme.Light">
    <item name="android:tabWidgetStyle">@style/LightTabWidget</item>
</style>

<style name="LightTabWidget" parent="@android:style/Widget.TabWidget">
    <!-- set textColor to red, so you can verify that it applied. -->
    <item name="android:textColor">#f00</item>
</style>

Then I just apply that theme to my application by adding android:theme="@style/MyTheme" to the <application /> element of my AndroidManifest.xml.

检查我的这个答案:选项卡小部件中的背景忽略缩放

也可以参考android.graphics.drawable package

在您的代码中,您可以像这样设置选项卡的背景:

tabHost.getTabWidget().getChildAt(0).setBackgroundResource(
            android.R.color.white);

Check this answer of mine: Background in tab widget ignore scaling

You can also refer to the android.graphics.drawable package

In your code, you can set the background for your tabs like this:

tabHost.getTabWidget().getChildAt(0).setBackgroundResource(
            android.R.color.white);

public void onCreate(Bundle savingInstanceState)

           `tabHost = getTabHost();
            tabHost.setOnTabChangedListener(this);
    tabHost.setCurrentTab(0);
    setTabColor();`

比在侦听器中:

public void onTabChanged(String tabId) {
设置选项卡颜色();

最后是设置前景和背景的函数:

public void setTabColor() {
    // set foreground color:
    for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) {
        RelativeLayout rl = (RelativeLayout) tabHost.getTabWidget().getChildAt(i);
        ImageView imageView = (ImageView) rl.getChildAt(0);// change it if you want it
        TextView textView = (TextView) rl.getChildAt(1);//          
        textView.setTextColor(Color.parseColor("#FFFFFF"));
    }

    // set background color:
    for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) {
        tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#010101")); // unselected
    }
    tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#121288")); // selected
}

in the public void onCreate(Bundle savedInstanceState)

           `tabHost = getTabHost();
            tabHost.setOnTabChangedListener(this);
    tabHost.setCurrentTab(0);
    setTabColor();`

than in the listener:

public void onTabChanged(String tabId) {
setTabColor();

finally the function, which set the foreground and the background too:

public void setTabColor() {
    // set foreground color:
    for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) {
        RelativeLayout rl = (RelativeLayout) tabHost.getTabWidget().getChildAt(i);
        ImageView imageView = (ImageView) rl.getChildAt(0);// change it if you want it
        TextView textView = (TextView) rl.getChildAt(1);//          
        textView.setTextColor(Color.parseColor("#FFFFFF"));
    }

    // set background color:
    for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) {
        tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#010101")); // unselected
    }
    tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#121288")); // selected
}

在 onCreated() 中:

    tabHost.setCurrentTab(0);

// Set tabs text color to white:
TabWidget tabWidget = tabHost.getTabWidget();
int whiteColor = getResources().getColor(R.color.white);
int someOtherColor = getResources().getColor(R.color.someOtherColor);
for(int i = 0; i < tabWidget.getChildCount(); i++){
    View tabWidgetChild = tabWidget.getChildAt(i);
    if(tabWidgetChild instanceof TextView){
        ((TextView) tabWidgetChild).setTextColor(whiteColor);
    } else if(tabWidgetChild instanceof Button){
        ((Button) tabWidgetChild).setTextColor(whiteColor);
    } else if(tabWidgetChild instanceof ViewGroup){
        ViewGroup vg = (ViewGroup)tabWidgetChild;
        for(int y = 0; y < vg.getChildCount(); y++){
            View vgChild = vg.getChildAt(y);
            if(vgChild instanceof TextView){
                ((TextView) vgChild).setTextColor(whiteColor);
            }
        }
        vg.setBackgroundColor(someOtherColor);
    }
}

In onCreated() :

    tabHost.setCurrentTab(0);

// Set tabs text color to white:
TabWidget tabWidget = tabHost.getTabWidget();
int whiteColor = getResources().getColor(R.color.white);
int someOtherColor = getResources().getColor(R.color.someOtherColor);
for(int i = 0; i < tabWidget.getChildCount(); i++){
    View tabWidgetChild = tabWidget.getChildAt(i);
    if(tabWidgetChild instanceof TextView){
        ((TextView) tabWidgetChild).setTextColor(whiteColor);
    } else if(tabWidgetChild instanceof Button){
        ((Button) tabWidgetChild).setTextColor(whiteColor);
    } else if(tabWidgetChild instanceof ViewGroup){
        ViewGroup vg = (ViewGroup)tabWidgetChild;
        for(int y = 0; y < vg.getChildCount(); y++){
            View vgChild = vg.getChildAt(y);
            if(vgChild instanceof TextView){
                ((TextView) vgChild).setTextColor(whiteColor);
            }
        }
        vg.setBackgroundColor(someOtherColor);
    }
}
