How do I get rid of this black bar during animation?

Question

I'm trying to perform a custom animation on an Activity transition. The activity is supposed to slide smoothly upward instead of from the side. It works, but the view has a black bar (the same size as the status bar) on the top of the view. How can I get rid of the black bar? Here is the code I'm using:

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  requestWindowFeature(Window.FEATURE_NO_TITLE);
  overridePendingTransition(R.anim.upin, R.anim.upout);
  setContentView(R.layout.screen_login);
}

the animation upin:

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromYDelta="100%" android:toYDelta="0%" android:duration="500" />
</set>

the animation upout:

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromYDelta="0%" android:toYDelta="0%" android:duration="500" />
</set>

EDIT: If I make all the Activities fullscreen it works perfectly. Of course, I don't WANT all the Activities to be fullscreen.

Okay, found a way of doing this. In the activity that you are animating to, override your onCreate method. Before you call setContentView (I don't know if this is necessary, but it's the order in which I did it), add this code snippet:

ColorDrawable colorDrawable = new ColorDrawable( Color.TRANSPARENT );
getWindow().setBackgroundDrawable( colorDrawable );

This worked like a charm for me and I haven't seen any other side effects as of yet.

I actually ran into the same issue and stumbled upon your question. Hope you find this helpful.

You can also get the same effect by setting your activity's theme to `Theme.Translucent` in the manifest. Like here: http://stackoverflow.com/a/6468734/483708 – Theo Jan 20 '12 at 18:58
I did something simlar but I have a background picture on my layout. I used the following code to handle that: getWindow().setBackgroundDrawableResource(R.drawable.picture); – MinceMan Jan 22 '12 at 05:24
Turns out that setting Theme.Translucent interferes with overridePendingTransition animations (in my case the exit animation was not being played). The OP's solution has no such issues. – Theo Mar 11 '12 at 01:26
In my case I have another Activity come on top of one. So setting the background to be transparent doesnt work. Will post once I have a solution – Zen Apr 06 '14 at 16:20
@groomsy This is making the entire activity transparent except for the black bar, which is gray now, – the_prole Oct 07 '15 at 11:10

I know this question is pretty old, but I ran into the same problem (black bar/space at the top of the activity) and this fixed it for me:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    getWindow().setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,
            WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

    setContentView(R.layout.your_layout);
}

Hopefully this will help somebody who stumbles upon this question :)

Okay, I tried a few things, like making the deltas relative to the parent, etc. I think the core problem is that the activity has extra space at the top, which is that black bar. There's not really anything to be done about it as far as I can see except to pull it out of the activity and make it a view.

Placing that view into a ViewAnimator and then setting the in and out transitions to those I already listed works like a charm. I'm fairly convinced that there is no other way to do this. If anyone ever figures one out, let me know, but this solves my problem.

What do you mean "pull it out of the activity and make it a view" — the_prole, Oct 08 '15 at 06:50
