rawerLayout是Library包中实现了侧滑菜单效果的控件，drawerLayout分为侧边菜单和主内容区两部分，侧边菜单可以根据手势展开与隐藏（drawerLayout自身特性），
一定要导入包
布局
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:id="@+id/draw"
android:layout_width="match_parent"
android:layout_height="match_parent"

fragment.xml 里面写一个pullToRefreshListView
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
