Android make transition on activity recreate()

Question

I would like to put a transition on activity recreate() after changing theme, is it possible?

I tried: @android:anim/fade_in @android:anim/fade_out but it didn't work, and that will also affect the transition when I open and close activity, but I don't want that

Completing @Yaro's answer,

Inside onCreate, if savedInstanceState is null, try the intent extras. The state of the views will be properly restored only if you call super.onCreate with a bundle.

public class ExampleActivity extends Activity {      @Override     protected void onCreate(@Nullable Bundle savedInstanceState) {         //setTheme(whatever);         super.onCreate(savedInstanceState != null ? savedInstanceState : getIntent().getBundleExtra("saved_state"));     }      protected void transitionRecreate(){         Bundle bundle = new Bundle();         onSaveInstanceState(bundle);         Intent intent = new Intent(this, getClass());         intent.putExtra("saved_state", bundle);         intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);         startActivity(intent);         overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);     }  } 

Worked for me, you can use finish() instead of the CLEAR_TOP flag
