I am troubled by how the Android OS is handling resizing on an app of mine. Basically I have a background image that is 480x800 (so 480px wide) and an image that goes at the bottom, also 480px wide.

On the Galaxy S (480x800 screen) everything looks fine, as shown below:



On the Galaxy S3 (720x1280), however, the background is getting stretched to 720px wide but the image at the bottom only to 640px wide, as shown below:



I tried to create a xhdpi folder with larger images, but same thing happens (background stretched to 720px, image only to 640px). I also tried to play with "ScaleType", but no luck so far.

Does anyone know why the OS would re-size the two images with a different scale, and how to fix it?
