XML drawable Bitmap tileMode bug?

Question

I'm having issues where my drawable resource uses the tileMode repeat. In some cases the image is just stretched and sometimes it is properly repeated.

The following are the xml files I use to create the button states:

Answer 1

This is a known bug, partially fixed in Android 3.0 and completely fixed in ICS.

Answer 2

We were having a similar problem writing for 3.2 on Sony's Google TV device. We noticed some very similar background-striping stemming from using android:tileMode="repeat" on a bitmap as a background image.

In this case, the fix was to turn off hardware acceleration on the view that contained the bitmap like so (from a function in our Activity):

View tile_holder = this.findViewById(R.id.tile_holder);
tile_holder.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
