有两种:
setCompoundDrawables 画的drawable的宽高是按drawable.setBound()设置的宽高，
所以才有The Drawables must already have had setBounds(Rect) called，即使用之前必须使用Drawable.setBounds设置Drawable的长宽。
而setCompoundDrawablesWithIntrinsicBounds是画的drawable的宽高是按drawable固定的宽高，
所以才有The Drawables' bounds will be set to their intrinsic bounds.即通过getIntrinsicWidth()与getIntrinsicHeight()获得。
