how to remove Black background between start new activity during slide_left animation?

Question

When I call new activity by animation the background gets black.
How can I remove remove the black background?

For the animation I'm using:

getWindow().setBackgroundDrawableResource(R.drawable.mainbg_);  overridePendingTransition (R.anim.push_up_in,0); 

Answer 1

Setting the Theme didn't work for me, but adding an exit animation did.

overridePendingTransition (R.anim.push_up_in,R.anim.hold); 

For the exit animation, I just used an animation that does nothing.

<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android">     <translate android:fromYDelta="0%p" android:toYDelta="0%p" android:duration="2000"/> </set> 

Answer 2

All you really need, especially if you already got a theme set to the activity and don't want to use the Theme.Translucent suggested is add the following to your activity/app's theme:

<item name="android:windowIsTranslucent">true</item>
