Android change background image with fade in/out animation

Question

I wrote code which can change background image random every 5 second.now i want to use fade in/out animation to change background image,but I do not know how I can use this

Answer 1

You can use relativeLayout, and add one layer of background view which set both height and width match_parent. All other UI element should put on top of this view. In your code. Define fadeOut and fadeIn animation. Find that background view by id, then do this:

 xxxBackground.startAnimation(fadeOut);
 xxxBackground.setBackgroundResource(R.drawable.your_random_pic);
 xxxBackground.startAnimation(fadeIn);

You can use some interpolator to tune the performance.
