使用CoordinatorLayout

CoordinatorLayout是在 Google IO/15 大会发布的，遵循Material 风格，包含在 support Library中，结合AppbarLayout, CollapsingToolbarLayout等 可 产生各种炫酷的效果

简单的一个例子

库 compile 'com.android.support:design:24.2.1'

直接使用布局

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
