Android - Setting both TileMode and Gravity

问题

I have a ListView in an XML-layout. I want to set a new background to this view by using the following code:

BitmapDrawable TileMe = new BitmapDrawable(BitmapFactory.decodeResource(getResources(), R.drawable.bg_skyline));
TileMe.setGravity(Gravity.BOTTOM); // Bottom
TileMe.setTileModeX(Shader.TileMode.REPEAT);
ListView test = getListView();
test.setBackgroundDrawable(TileMe);

The problem is that if I leave both the Gravity and the TileMode lines uncommented, only TileMode will work. If i comment the TileMode line, the Gravity line will work.

Am I doing something wrong or is Android messing with my head?

回答1:

Gravity is ignored when the tile mode is enabled. Link
