Android - How to animate an activity transition when the default back button is pressed

android, animation, back, button, transition

Solution

maybe you can do this work in onBackPressed() method in the activity.

@Override
public void onBackPressed() {
    super.onBackPressed();
    overridePendingTransition(R.anim.comming_in, R.anim.comming_out);   
}

Problem

In my activity, I have a button with the following click listener that is working great: ``` final ImageButton startOverButton = (ImageButton) findViewById(R.id.start_over_button); startOverButton.setOnClickListener(new View.OnClickListener(){ @Override public void onClick(final View v) { finish();//go back to the previous Activity overridePendingTransition(R.anim.comming_in, R.anim.comming_out); } }); ``` It animates the return to the previous activity the way I want. However, when the user presses the Android default back button, the animation is not triggered. My question is: where should I put the animation code overridePendingTransition(R.anim.comming_in, R.anim.comming_out); so that this animation will be triggered both when the user clicks on my button and in the default Android back button? As a naive try, I have tried to put the overridePendingTransition(R.anim.comming_in, R.anim.comming_out); line of code in the onDestroy() method but it did not work. Thank you in advance!
