问题 I'm trying to set an image as background of the Sherlock Action Bar, but even if the it's 720 x 112 px, it seems like the image doesn't stretch.

You can do something like this, assuming your newColors Array is an int Array with the resource ids? String colorId = "tColor"; Resources resources = getResources(); for (int i = 0; i < numTrails; i++) {
