Make activity animate from top to bottom

Question

I am writing an Android app where I want the activity to appear by animating in from the bottom of the screen to the top. I am able to do this with code from here:

Answer 1

Two ways of doing this:

1. Using styles

Assuming you wish to implement this for all activities, in your base theme define the following entry:

@style/ActivityAnimations

Then define the following style:

Where @anim/hold can be something like this:

2. Using overridePendingTransition()

Override finish():

  @Override
  public void finish() {
    super.finish();
    overridePendingTransition(R.anim.hold, R.anim.disappear_to_bottom);
  }

Override onBackPressed():

  @Override
  public void onBackPressed() {
    finish();
  }

Override onOptionsItemSelected():

  @Override
  public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
      case android.R.id.home:
        finish();
        return true;
    }
    return super.onOptionsItemSelected(item);
  }
