I am trying to tile a 20x20 background onto my Custom View but for some reason I am unable too.

 BitmapDrawable background; background = new BitmapDrawable(BitmapFactory.decodeResource(getResources(), R.drawable.back)); background.setTileModeXY(Shader.TileMode.REPEAT, Shader.TileMode.REPEAT); background.draw(canvas);

Does anyone have an idea why it isn't working?

Don't set the bounds to the size of the tile: set them to the total area to be tiled. In your case:

background.setBounds(0, 0, myView.getWidth(), myView.getHeight());

You forgot to give your drawable bounds. You need to call drawable.setBounds() at least once before drawing it.

What bounds should I set if I want the image to be tiled all over the screen though? Setting to (0, 0, 20, 20) gives me the same problem, it doesn't appear.

I seem to have fixed this problem with the following code

//background Bitmap _back_bmp = BitmapFactory.decodeResource(context.getResources(), R.drawable.background); BitmapDrawable backTiled = new BitmapDrawable(_back_bmp); backTiled.setTileModeXY(Shader.TileMode.REPEAT, Shader.TileMode.REPEAT); backTiled.setBounds(0, 0, this.getWidth(), this.getHeight()); this.back_bmp = backTiled.getTileModeX(); this.setBackgroundDrawable(backTiled);

But I have my own problem now. Nothing can be drawn to the canvas?
