概述

• 谷歌官方推出这个百分比库对android的屏幕适配肯定有很大的帮助，当然具体好不好用还得根据不同的使用场景来分析。
• 这个支持包里的内容有：百分比相对布局PercentRelativeLayout，百分比帧布局PercentFrameLayout，百分比线性布局PercentLinearLayout。

先跑demo

• 赶紧来尝鲜吧。我先对原来的工程做了拆分： 
  
  1. lib库工程，仅包含百分比控件的源代码和必要的资源。完整代码路径：https://github.com/cheyiliu/test4XXX/tree/master/androidSupportPercent
  2. demo工程(基于百分比库)，同时去掉了原工程对v7 support包的依赖，完整路径：https://github.com/cheyiliu/test4XXX/tree/master/test4androidSupportPercentLayout

代码分析和使用

库的实现

• 自定义属性，支持的属性包括：百分比宽高和百分比margin

• 继承现有控件并应用自定义属性。android view的布局和绘制要大致经历onMeasure onLayout onDraw几步，那百分比属性的应用肯定是在onMeasure过程中了。以PercentRelativeLayout为例简单过下代码。

<code class="hljs java has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined;

box-sizing: border-box;">1.</span>类PercentLayoutInfo用来存储自定义的百分比属性，可理解为百分比属性model。<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">2.</span>类LayoutParams，继承原有的layoutparam并持有百分比属性model类。在构造时完成对model的赋值。    <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">public</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">static</span> <span class="hljs-class" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136);

       <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">public</span> <span class="hljs-title" style="box-sizing: border-box;">LayoutParams</span>(Context c, AttributeSet attrs) {            <span class="hljs-keyword" style="color: rgb(0, 0, 136);

box-sizing: border-box;">int</span> heightMeasureSpec) {        mHelper.adjustChildren(widthMeasureSpec, heightMeasureSpec);        <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">super</span>.onMeasure(widthMeasureSpec, heightMeasureSpec);        <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">if</span> (mHelper.handleMeasuredStateTooSmall()) {            <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">super</span>.onMeasure(widthMeasureSpec, heightMeasureSpec);        }    }</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238);

使用库

• 首先建立和库工程的依赖关系
• 在layout文件中使用

<code class="hljs xml has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined;
