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

Question

when i call new activity by animation the background make black so i want to remove black back ground so how can i achieve this? ? For animation i use

 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.
