DrawerLayout实现双向侧滑

1.首先来欣赏下效果图

2.先看看activity_main的布局，DrawerLayout里第一个布局时主内容，第二个布局是左侧，第三个布局是右侧。

 1 <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
 2     xmlns:tools="http://schemas.android.com/tools"
 3     android:id="@+id/id_drawerLayout"
 4     android:layout_width="match_parent"
 5     android:layout_height="match_parent"
 6     android:background="@drawable/img_frame_background" >
 7 
 8     <RelativeLayout
 9         android:layout_width="match_parent"
10         android:layout_height="match_parent"
11         android:background="@drawable/qq" >
12 
13         <Button
14             android:layout_width="40dp"
15             android:layout_height="30dp"
16             android:layout_marginTop="10dp"
17             android:layout_alignParentRight="true"
18             android:background="@drawable/youce"
19             android:onClick="OpenRightMenu" />
20     </RelativeLayout>
21 
22     <fragment
23         android:id="@+id/id_left_menu"
24         android:name="com.watson.lv.drawerlayoutdemo.MenuLeftFragment"
25         android:layout_width="200dp"
26         android:layout_height="match_parent"
27         android:layout_gravity="left"
28         android:tag="LEFT" />
29 
30     <fragment
31         android:id="@+id/id_right_menu"
32         android:name="com.watson.lv.drawerlayoutdemo.MenuRightFragment"
33         android:layout_width="100dp"
34         android:layout_height="match_parent"
35         android:layout_gravity="right"
36         android:tag="RIGHT" />
37 
38 </android.support.v4.widget.DrawerLayout>

3.layout_menu是左侧布局

  1 <?xml version="1.0" encoding="utf-8"?>

  6 
  7     <LinearLayout
  8         android:layout_width="match_parent"
  9         android:layout_height="wrap_content"
 10         android:layout_centerVertical="true"
 11         android:orientation="vertical" >
 12 
 13         <RelativeLayout
 14             android:layout_width="match_parent"
 15             android:layout_height="wrap_content" >
 16 
 17             <ImageView

 24                 android:src="@drawable/img_1" />
 25 
 26             <TextView

4.menu_layout_right是右侧布局。

 1 <?xml version="1.0" encoding="utf-8"?>

5.最后展示出MainActivity
