手工设置文本与图片相对位置

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，
