Android(安卓)百分比布局

看到一片博客关于android的百分比布局，自己动手写了一下，效果还可以。博客地址： http://blog.csdn.net/lmj623565791/article/details/46767825

1、在APP - build.gradle中添加如下代码

2、布局示例 <RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android"
xmlns: tools = "http://schemas.android.com/tools"
android :layout_width= "match_parent"
android :layout_height= "match_parent"
tools :context= ".MainActivity" >

<android.support.percent.PercentRelativeLayout
xmlns: android = "http://schemas.android.com/apk/res/android"
xmlns: app = "http://schemas.android.com/apk/res-auto"
android :layout_width= "match_parent"
android :layout_height= "200dip" >

<View
android :id= "@+id/top_left"
android :layout_width= "0dp"
android :layout_height= "0dp"
android :layout_alignParentTop= "true"
android :background= "#ff0000"
app :layout_heightPercent= "30%"
app :layout_widthPercent= "70%" />

<View
android :id= "@+id/top_right"
android :layout_width= "0dp"
android :layout_height= "0dp"
android :layout_alignParentTop= "true"
android :layout_toRightOf= "@+id/top_left"
android :background= "#00ff00"
app :layout_heightPercent= "30%"
app :layout_widthPercent= "30%" />

<View
android :id= "@+id/centre"
android :layout_width= "match_parent"
android :layout_height= "0dp"
android :layout_below= "@+id/top_left"
android :background= "#0000ff"
app :layout_marginLeftPercent= "10%"
app :layout_marginRightPercent= "20%"
app :layout_marginTopPercent= "10%"
app :layout_marginBottomPercent= "10%"
app :layout_heightPercent= "40%" />

<View
android :layout_width= "match_parent"
android :layout_height= "0dp"
android :id= "@+id/bottom"
android :layout_below= "@+id/centre"
android :background= "#00f0ff"
android :layout_alignParentLeft= "true"
android :layout_alignParentStart= "true"
app :layout_heightPercent= "10%" />
</android.support.percent.PercentRelativeLayout>

</RelativeLayout>
