drawerLayout其实是一个布局控件，跟LinearLayout等控件是一样的，但是drawerLayout带有滑动的功能。只要按照drawerLayout的规定布局方式写完布局，就能有侧滑的效果。
1）在DrawerLayout中，第一个子View必须是显示内容的view，并且设置它的layout_width和layout_height属性是match_parent.
2)第二个view是抽屉view,并且设置属性layout_gravity="left|right",表示是从左边滑出还是右边滑出。设置它的layout_height="match_parent"
ActionBarDrawerToggle就是DrawerLayout事件的监听器。
ActionBarDrawerToggle有3个方法可以被复写，分别用来实现DrawerLayout打开，关闭，滑动的事件监听：
drawerLayout布局代码：
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/drawer_layout"
>
//主内容
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:gravity="center"
android:id="@+id/drawer_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="123"/>
</FrameLayout>
//侧滑菜单
<ListView
android:id="@+id/left_drawer"
android:layout_width="40dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#111" />
</android.support.v4.widget.DrawerLayout>
