require

• support appcompat 23.2.0 or above
• activity extends AppCompatActivity
• follow Android official nigh model guidance

use

1. set NightModel in Application

   public class AppApplication extends Application {
   
   @Override
   public void onCreate() {
       super.onCreate();
       NightModelManager.getInstance().init(this);
       ...
   }
   }
   
   

2. attach and detach in Activity which need refresh, not every Activity

   public class MainActivity extends AppCompatActivity {
    @Override
   protected void onCreate(Bundle savedInstanceState) {
   		// must before super.onCreate
       NightModelManager.getInstance().attach(this);
       super.onCreate(savedInstanceState);
   }
   
   ...
   
   @Override
   protected void onDestroy() {
       NightModelManager.getInstance().detach(this);
       super.onDestroy();
   }
   }
   

3. call night/day method

   private void changeNightModel() {
   if (NightModelManager.getInstance().isCurrentNightModel(this)) {
   	NightModelManager.getInstance().applyDayModel(this);
   } else {
   	NightModelManager.getInstance().applyNightModel(this);
    	}
   }
   

warn

1. this lib used for resolving the problem that official night model can not refresh started Activities. So, only attach and detach in Activities that need refresh. It's a supplementary lib for official night model.

2. When create View dynamically in attached Activity with code, you should write like this:

   View view = LayoutInflater.from(MainActivity.this).inflate(R.layout.item_layout, parentView, false);
   

   because the lib need cache this View, use LayoutInflater.from(MainActivity.this) will use the proxy LayoutInflaterFactory create this View and cache it

3. style:@style/xx just support TextView (android:textColor or android:textSize) now
