Make new activity appear behind old one during transition

Question

What I\'m trying to achieve is to override the start activity animation.

The animation should give the impression that the old activity is on top of the new activity

Answer 1

Actually, I've found a property called android:zAdjustment in the animation files.

If I put android:zAdjustment="bottom" in hold.xml (screen 2) and android:zAdjustment="top" in push_down_out.xml (screen 1) then I can get the desired effect.

This gets around the z order issue (I assumed it was an issue with animation timings so I was barking up the wrong tree).

Answer 2

The solution that works for me:

R.anim.exit_slide_down

<set xmlns:android="http://schemas.android.com/apk/res/android" 
     android:zAdjustment="top">  

    <translate android:fromYDelta="0" 
               android:toYDelta="100%p" 
               android:duration="600" />
</set>

...and then

Intent intent = new Intent(activity, SecondActivity.class);
startActivity(intent);
activity.overridePendingTransition(0, R.anim.exit_slide_down);

I've been trying to solve your solution in a sample project and I got it working with this code:

Call the animation with:

startActivity(new Intent(this, Activity2.class));
overridePendingTransition(R.anim.push_down_in,R.anim.push_down_out);

R.anim.push_down_in:

<?xml version="1.0" encoding="utf-8"?>  
<set xmlns:android="http://schemas.android.com/apk/res/android">  
  <translate android:fromYDelta="-100%p" android:toYDelta="0" android:duration="300"/>
</set>  

R.anim.push_down_out:

<?xml version="1.0" encoding="utf-8"?>  
<set xmlns:android="http://schemas.android.com/apk/res/android">  
  <translate android:fromYDelta="0" android:toYDelta="100%p" android:duration="300"/>
</set>
