如何捕获通过单击android活动右上角的X引起的事件

Question

I'd like to know what event Android issues when clicking on the top-right X of an Activity. I've tried onStop() and onDestroy() , but they don't get called at all.

Please note that I'm using AppTheme.NoActionBar as app theme, and my Activity extends AppCompatActivity.

Also, is it possible to remove the top-right X button (but keep drop-down menu)?

Looking at that image ,you are at "recently used" (or whatever it's called) section of your device. If you are at that screen , onStop() is already called for your activity and when you click the X (close app) button , onDestroy() will be called.

Override those lifecycle methods , onPause onStop etc and place Log statements inside them. Like this : Log.d("lifecycle","onStopCalled"); and check your logcat whats happening
