setCompoundDrawables和setCompoundDrawablesWithIntrinsicBounds区别
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。
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.
使用之前必须使用Drawable.setBounds设置Drawable的长宽。
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,
