手工设置文本与图片相对位置时,常用到如下方法:
setCompoundDrawables(left, top, right, bottom);
setCompoundDrawablesWithIntrinsicBounds(left, top, right, bottom)
意思是设置Drawable显示在text的左、上、右、下位置。
(Textview、Button都可以)
但是两者有些区别:
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.
意思是说使用之前必须使用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,
即通过getIntrinsicWidth()与getIntrinsicHeight()获得,所以才有
