Implement night mode in your application.

1. Create a folder app --> res --> values-night

2. Copy and paste from colors.xml and styles.xml from values folder

3. Make changes in styles and colors

colors.xml :

    <?xml version="1.0" encoding="utf-8"?>
    <resources>
        <color name="colorPrimary">#008577</color>
        <color name="colorPrimaryDark">#00574B</color>
        <color name="colorAccent">#D81B60</color>

        <color name="colorWhite">#FFFFFF</color>
        <color name="colorBlack">#000000</color>
    </resources>

styles.xml (use DayNight theme Theme.AppCompat.DayNight.DarkActionBar)

      <resources>

          <style name="AppTheme" parent="Theme.AppCompat.DayNight.DarkActionBar">
              <item name="colorPrimary">@color/colorPrimary</item>
              <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
              <item name="colorAccent">@color/colorAccent</item>
              <item name="android:windowBackground">@color/colorBlack</item>
              <item name="android:textColorPrimary">@color/colorWhite</item>
              <item name="android:textColorSecondary">@color/colorWhite</item>
          </style>

      </resources>

4. Create Application class and add into manifest file. this application class will handle to app scrren

         public class MyApplication extends Application {

          @Override
          public void onCreate() {
              super.onCreate();
              // AppCompatDelegate.MODE_NIGHT_NO,   AppCompatDelegate.MODE_NIGHT_YES, AppCompatDelegate.MODE_NIGHT_AUTO
              AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_AUTO);
          }
      }

5. To implement special in Activity write code in activity otherwise write code on application.

AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_AUTO);

before super().

Example :

      public class MainActivity extends AppCompatActivity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {

            // AppCompatDelegate.MODE_NIGHT_NO,   AppCompatDelegate.MODE_NIGHT_YES, AppCompatDelegate.MODE_NIGHT_AUTO
            AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);

            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);


        }
    }
