<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:app="http://schemas.android.com/apk/res-auto"
     android:id="@+id/drawer_layout"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:fitsSystemWindows="true">
     <!-- Your contents -->
     <android.support.design.widget.NavigationView
         android:id="@+id/navigation"
         android:layout_width="wrap_content"
         android:layout_height="match_parent"
         android:layout_gravity="start"
         app:headerLayout="@layout/drawer_header"
         app:itemTextColor="@color/item_text_color"
         app:menu="@menu/drawer" />
 </android.support.v4.widget.DrawerLayout>

app:itemTextColor、 app:itemBackground分别设置item字体和背景颜色

    <item android:color="@color/primary" android:state_checked="true" />
    <item android:color="@color/black" />
</selector>

其中最重要的就是这两个属性：

app:headerLayout
app:menu

通过这两个属性，我们可以非常方便的指定导航界面的头布局和菜单布局。

    //设置头像，布局app:headerLayout="@layout/drawer_header"所指定的头布局
    View view = navigationView.inflateHeaderView(R.layout.drawer_header);
    TextView userName = (TextView) view.findViewById(R.id.userName);
    userName.setText(R.string.author);
    //View mNavigationViewHeader = View.inflate(MainActivity.this, R.layout.drawer_header, null);
    //navigationView.addHeaderView(mNavigationViewHeader);//此方法在魅族note 1，头像显示不全
    //菜单点击事件
    navigationView.setNavigationItemSelectedListener(new NavigationItemSelected());
}
