Answer 1

ScaleDrawable not only allows you to scale a drawable, it also allows you to control the scale using setLevel on the ScaleDrawable itself. But the ScaleDrawable doesn't change the intrinsic width and height of the drawable As @m039 pointed out, the ScaleDrawable source actually does a strange thing: when the original drawable's level is set to 0, the scaleDrawable itself won't draw.

To take effect of the scale, you have to do something like this:

ScaleDrawable scaleDrawable = (ScaleDrawable) imageView.getDrawable();
scaleDrawable.setLevel(10000);
or 
scaleDrawable.setLevel(5000);
