Make New Activity Appear Behind Old One During Transition

Make new activity appear behind old one during transition

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).

Android new fragment appears below old one during fragment animation

If fragment appears below another one is because the fragment container is not the good container type

You need to put fragment inside FrameLayout or RelativeLayout, if you want to test you can paste your fragment layout code at the bottom of the fragment container for have a preview

How to change the way a new activity starts in android?

You can use the overridePendingTransition()method in Activity class to change the transition.Here are a good tutorial for this topic, the link.
But I should mention the point that animation can be disable in phone setting and in this situation your animation transition wont show.

Can I change the Android startActivity() transition animation?

In the same statement in which you execute finish(), execute your animation there too. Then, in the new activity, run another animation. See this code:

fadein.xml

<set xmlns:android="http://schemas.android.com/apk/res/android" 
     android:fillAfter="true">
     <alpha android:fromAlpha="1.0" 
            android:toAlpha="0.0"
            android:duration="500"/> //Time in milliseconds
</set>

In your finish-class

private void finishTask() {
    if("blabbla".equals("blablabla"){
        finish();
        runFadeInAnimation();
    }
}

private void runFadeInAnimation() {
    Animation a = AnimationUtils.loadAnimation(this, R.anim.fadein);
    a.reset();
    LinearLayout ll = (LinearLayout) findViewById(R.id.yourviewhere);
    ll.clearAnimation();
    ll.startAnimation(a);   
}

fadeout.xml

<set xmlns:android="http://schemas.android.com/apk/res/android"
           android:fillAfter="true">
  <alpha android:fromAlpha="0.0"
         android:toAlpha="1.0"
         android:duration="500"/>
</set>

In your new Activity-class you create a similiar method like the runFadeAnimation I wrote and then you run it in onCreate and don't forget to change the resources id to fadeout.

Add animation to new Activity

The problem was my phone, I had disable this option:

Settings->Developer options -> Transition animation scale

How to override onBackPressed() with overridePendingTransition() animation

According to documentation, the first argument to overridePendingTransition is the animation used for the incoming activity, ie. your MainActivity. And the second argument is used for the outgoing activity, ie. your PlayPanel.

play_panel_close_background.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:zAdjustment="top">
    <translate
        android:fromYDelta="0%"
        android:toYDelta="100%"
        android:duration="600"
        />
</set>

@Override
public void onBackPressed() {
    //super.onBackPressed();
    startActivity(new Intent(this, MainActivity.class));
    overridePendingTransition(
            0,
            R.anim.play_panel_close_background
    );
}
