support-lib
这个库为我们提供了什么呢?
<li>两种布局:
<pre>PercentRelativeLayout,PercentFrameLayout,他们继承自FrameLayout和RelativeLayout两个容器类;</pre>
<li>支持的属性有:
<pre>
占宽比,占高比
layout_widthPercent
layout_heightPercent
左上右下,开始,结束,外边距比例
layout_marginLeftPercent
layout_marginTopPercent
layout_marginRightPercent
layout_marginBottomPercent
layout_marginStartPercent
layout_marginEndPercent
</pre>
也就是说,只要在开发过程中使用PercentRelativeLayout、PercentFrameLayout替换FrameLayout、RelativeLayout即可。
