1、概述

之前写了一个Android 高仿 QQ5.0 侧滑菜单效果 自定义控件来袭 ，恰逢QQ5.2又加了一个右侧菜单，刚好看了下DrawerLayout，一方面官方的东西，我都比较感兴趣；另一方面，这玩意用起来的确方便，于是简单写了个demo，高仿QQ5.2双向侧滑，分享给大家。

首先看看效果图：

DrawerLayout用起来真的很方便，下面一起看看用法~

2、DrawerLayout的使用

直接将DrawerLayout作为根布局，然后其内部第一个View为内容区域，第二个View为左侧菜单，第三个View为右侧侧滑菜单，当前第三个是可选的。

第一个View的宽高应当设置为match_parent，当然了，这也理所当然。

第二、三个View需要设置android:layout_gravity="left"，和android:layout_gravity="right"且一搬高度设置为match_parent，宽度为固定值，即侧滑菜单的宽度。

按照上面的描述写个布局文件，然后设置给Activity就添加好了左右侧滑了，是不是很简单~~~

比如我们的布局文件：

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"      xmlns:tools="http://schemas.android.com/tools"      android:id="@+id/id_drawerLayout"      android:layout_width="match_parent"      android:layout_height="match_parent"      android:background="@drawable/img_frame_background" >        <RelativeLayout          android:layout_width="match_parent"          android:layout_height="match_parent"          android:background="@drawable/qq" >            <Button              android:layout_width="40dp"              android:layout_height="30dp"               android:layout_marginTop="10dp"              android:layout_alignParentRight="true"              android:background="@drawable/youce"              android:onClick="OpenRightMenu" />      </RelativeLayout>        <fragment          android:id="@+id/id_left_menu"          android:name="com.zhy.demo_zhy_17_drawerlayout.MenuLeftFragment"          android:layout_width="200dp"          android:layout_height="match_parent"          android:layout_gravity="left"          android:tag="LEFT" />        <fragment          android:id="@+id/id_right_menu"          android:name="com.zhy.demo_zhy_17_drawerlayout.MenuRightFragment"          android:layout_width="100dp"          android:layout_height="match_parent"          android:layout_gravity="right"          android:tag="RIGHT" />    </android.support.v4.widget.DrawerLayout>

菜单用的两个Fragment，左侧为200dp，右侧为100dp；

好了，看了我们的布局文件，接下来看下我们的详细代码。

3、代码是最好的老师

3、MainActivity

MainActivity的布局文件已经贴过了~~
