即使在杀死应用程序后，如何保持黑暗模式？

这是我在stay.java类中的代码。我已经实现了这样的设置课。我想在杀死该应用程序的情况下以深色为主题，也必须在那里存在，并且必须遵守切换。

现在我已经成就了黑暗。但是当我杀死该应用程序并再次来时，它消失了。切换也可以关闭。

public class settings extends AppCompatActivity {
    SwitchCompat switchCompat;
    ImageView backbtn;
    Button button;    
    @SuppressLint("WrongViewCast")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_settings);
        if (AppCompatDelegate.getDefaultNightMode() == AppCompatDelegate.MODE_NIGHT_YES) {
            setTheme(R.style.Base_ThemeOverlay_AppCompat_Dark);
        } else {
            setTheme(R.style.Base_Theme_MaterialComponents_Light);
        }
            backbtn = findViewById(R.id.goingback);
        LoadingDialod loadingDialod = new LoadingDialod(settings.this);

        backbtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(getApplicationContext(), MainActivity.class);
                startActivity(intent);
            }
        });
        switchCompat.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
                if (isChecked) {
                    loadingDialod.startloadinganimation();

                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {                             AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);
                            Intent intent = new Intent(getApplicationContext(), settings.class);
                            startActivity(intent);
                        }
                    }, 800);

                } else {
                    AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);

                }
            }
        });
    }
}

This is my code in settings.java class. I have implemented my settings class like this. I want to make dark theme on and after killing the app it has to be present there as well and toggle has to be trued on.

Now I have achieved to make it dark. But when I kill the app and come again it gets disappeared. Toggle is also get turns off.

public class settings extends AppCompatActivity {
    SwitchCompat switchCompat;
    ImageView backbtn;
    Button button;    
    @SuppressLint("WrongViewCast")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_settings);
        if (AppCompatDelegate.getDefaultNightMode() == AppCompatDelegate.MODE_NIGHT_YES) {
            setTheme(R.style.Base_ThemeOverlay_AppCompat_Dark);
        } else {
            setTheme(R.style.Base_Theme_MaterialComponents_Light);
        }
            backbtn = findViewById(R.id.goingback);
        LoadingDialod loadingDialod = new LoadingDialod(settings.this);

        backbtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(getApplicationContext(), MainActivity.class);
                startActivity(intent);
            }
        });
        switchCompat.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
                if (isChecked) {
                    loadingDialod.startloadinganimation();

                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {                             AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);
                            Intent intent = new Intent(getApplicationContext(), settings.class);
                            startActivity(intent);
                        }
                    }, 800);

                } else {
                    AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);

                }
            }
        });
    }
}

我已经给出了有关此但是我也在这里提供：

创建一个名为preverences Manager
的类
粘贴此代码的类
粘贴此代码

I have already given an answer about this here but I am giving it here also:

Create a class named Preferences Manager
Paste this code in the class

????

public final SharedPreferences sharedPreferences;

public PreferenceManager(Context context){
    sharedPreferences=context.getSharedPreferences( "PREFS",Context.MODE_PRIVATE );
}
public void putBoolean(String key,Boolean value){
    SharedPreferences.Editor editor = sharedPreferences.edit();
    editor.putBoolean( key,value );
    editor.apply();
}
public Boolean getBoolean (String key,Boolean defaultValue){
    return sharedPreferences.getBoolean( key,defaultValue );
}

public void clear(){
    SharedPreferences.Editor editor = sharedPreferences.edit();
    editor.clear();
    editor.apply();
}

Then in the fragment make an object named preferences manager like this.
PreferencesManager preferencesManager = new PreferencesManager(getActivity());
Then add value to it like this

if night mode is set to on.

preferencesManager.putBoolean("NightMode",true);

if night mode is off

preferencesManager.putBoolean("NightMode",false);

and then later to check if night mode if on or off, use this code

if (preferencesManager.getBoolean("NightMode")){
    //night mode is on ,do some magic
}else {
    //night mode is off ,do some magic
}

Edit

Alternatively you can also use my library here to store the data. To store and retrieve, see the README.md file

该答案提供了Android的适应深夜模式。深色主题适用于Android 10（API级别29）且更高。这是一个先决条件。

对于API 29 -API 30 ，

如果要在应用程序中全球启用Dark Night模式，则需要满足以下条件：

相应的活动应从AppCompatactivity继承。

在适当的位置调用以下代码，以在应用程序中启用全局暗模式。

  appcompatdelegate.setdefaultnightnightmode（appcompatdelegate.mode_night_yes）

对于API 31及以上的API ，

如果您想在应用程序中全球启用深夜模式，则需要满足以下条件：

获取UimodeManager。
在
GetSystemService（UI_Mode_Service）作为UimodeManager
}
在适当的位置调用以下代码，以在应用程序中启用全局暗模式。
```
  uimanager.setapplicationnightnightmode（uimodemanager.mode_night_yes）
 
```

This answer provides Android's adaptation to dark night mode. The dark theme is suitable for Android 10 (API level 29) and higher. This is a prerequisite.

For API 29 - API 30

If you want to enable dark night mode globally within the app, you need to meet the following conditions:

The corresponding Activity should inherit from AppCompatActivity.
Call the following code at the appropriate place to enable global dark mode in the application.
```
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES)
```

For API 31 and above

If you want to enable dark night mode globally within the app, you need to meet the following conditions:

Get UiModeManager .

private val uiManager: UiModeManager by lazy {
     getSystemService(UI_MODE_SERVICE) as UiModeManager
}

Call the following code at the appropriate place to enable global dark mode in the application.
```
uiManager.setApplicationNightMode(UiModeManager.MODE_NIGHT_YES)
```
