Navigation

##Navigation:列表组件

用法：导依赖

添加头布局：headerlayout：“头布局文件”

添加列表：新建Menu文件

设置title；

设置icon；

这些放在group里面

布局中添加列表：Menu=“列表文件”

Activity中：

getHeaderView（布局id）/findbyid（）；获得头文件的控件

setNavigationLinstener（）：列表布局的监听

布局文件：

// An highlighted block
android:id="@+id/main_drawer"
android:layout_
android:layout_>
android:id="@+id/main_navi"
android:layout_
android:layout_
android:layout_gravity="left"
app:menu="@menu/navimenu"
app:headerLayout="@layout/headerview"
>
android:layout_
android:layout_>
android:id="@+id/main_list"
android:layout_
android:layout_>




Menu文件

// An highlighted block
