How to make android browse to redraw its background? / Maybe the animation blocks its operation

Question

Is there any way to get android view to redraw its background? I set a flexible shape with a gradient as the background, which works great, but after changing the height of the view, you can see these ugly gradient steps.

What can I do? I tried view.invalidate()and view.refreshDrawableState()without visible differences.

Thank!

// EDIT: Here are a few more details and my code: After your answers, I think the bandages are the result of my probably bad code. That's what I'm doing:

• View scaling
• setting a new width and height, because the scaled view does not accept user input in other areas, and then the "old" (see android strange (at least for me) control behavior after scaling / does not accept input in the entire area )
• trying to set the background again (which contains a gradient and a rounded rectangle)

Here is my code:

public void onAnimationEnd(Animation animation)
{
    MyView view = (MyView) ((ExtendedScaleAnimation) animation).getView();
    view.getLayoutParams().width = toWidth;
    view.getLayoutParams().height = toHeight;
    view.clearAnimation();
    view.requestLayout();
    view.refreshBackground(); // background will be changed
}

On the device, you can see that the background image can be changed, but there is a flicker that seems to me like changing the background before the animation ends. Programmatically, it must be finished! Or am I wrong?

Thanks again!
