如果你的NavigationDrawer里面的Item没有响应，Drawer不能左滑关闭

如果你的NavigationDrawer里面的Item没有响应，Drawer不能左滑关闭，应该是因为你没有把主要内容放在DrawerLayout标签下的第一位。

The main content view (the FrameLayout above) must be the first child in the DrawerLayout because the XML order implies z-ordering and the drawer must be on top of the content.

比如把CoordinatorLayout放在NavigationDrawer的第一位。

The main content view (the FrameLayout above) must be the first child in the DrawerLayout because the XML order implies z-ordering and the drawer must be on top of the content.
The main content view is set to match the parent view's width and height, because it represents the entire UI when the navigation drawer is hidden.
The drawer view (the ListView) must specify its horizontal gravity with the android:layout_gravity attribute. To support right-to-left (RTL) languages, specify the value with "start" instead of "left" (so the drawer appears on the right when the layout is RTL).
The drawer view specifies its width in dp units and the height matches the parent view. The drawer width should be no more than 320dp so the user can always see a portion of the main content.

1、显示界面主要内容的View (上面的 FrameLayout ) 必须为DrawerLayout的第一个子View， 原因在于 XML 布局文件中的View顺序为Android系统中的 z-ordering顺序，而Navigation Drawer必须出现在内容之上。
2、显示界面内容的View宽度和高度设置为和父View一样，原因在于当Navigation Drawer不可见的时候，界面内容代表整个界面UI。
3、Navigation Drawer (上面的 ListView) 必须使用android:layout_gravity属性设置水平的 gravity值 .如果要支持 right-to-left (RTL，从右向左阅读)语言 用 "start" 代替 "left" (当在 RTL语言运行时候，菜单出现在右侧)。
4、抽屉菜单的宽度为 dp 单位而高度和父View一样。抽屉菜单的宽度应该不超过320dp，这样用户可以在菜单打开的时候看到部分内容界面。
