Android简单的自定义抽屉布局（DrawerLayout）

采用DrawerLayout的方法实现抽屉布局的效果，抽屉布局有两个部分，第一个部分为主内容区，如图中的包含底部菜单栏的部分。第二部分为侧边栏部分，左边部分。

对应xml布局如下：

其中的RelativeLayout布局所包含的内容即为主内容，其中第一个include进的布局为标题栏，类似于actionbar，第二个include进的为底部菜单栏，其中的FrameLayout用来填充fragment，点击对应的底部菜单后添加对应的fragment。

LinearLayout布局则对应的是侧边栏，include进来的是一个自定义布局，包括头像，名字，功能列表等。其中layout_gravity属性的值设为start则表示侧边栏从左往右滑动开启，设置为end则表示从右往左滑动开启。

由于不知道什么原因，如果你用activity直接继承OnClickListener()的方式监听点击事件的话并没有效果，因此本人采用直接设置监听器的方式来监听点击事件。
