Custom Back Button Animation

Question

The default animation when the Back button is pressed is a slide from left to right. I\'d like to replace that with a custom animation. I\'m currently thinking

Answer 1

I think you shouldn't use finish() because the data stored by the Views will be erased

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

Answer 2

Figured it out. I wasn't finshing the current activity. The following code does the trick.

@Override
public void onBackPressed() {
  [This Activity].this.finish();
  overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
}

Answer 3

I wouldn't use onBackPressed() since it's a hack when we use Fragments and we need to handle the stack, for instance. I proposed a more elegant solution here:

Answer 4

if you want no animation

follow the code in Activity

@Override
public void onBackPressed() {
    super.onBackPressed();
    overridePendingTransition(0,0);
}
