添加導航抽屜以空白活動

Question

我已經在空白活動（Android Studio）上創建了整個項目。我想添加一個導航抽屜而不妨礙我以前的代碼。是否有一種方法可以將導航抽屜添加到空白活動中，如果是的話請引導。

Answer 1

第1步：將導航視圖包含到您的xml文件中，這將通過創建時的yor活動進行膨脹。

<?xml version="1.0" encoding="utf-8"?> 

<include 
    layout="@layout/app_bar_main" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" /> 

<android.support.design.widget.NavigationView 
    android:id="@+id/nav_view" 
    android:layout_width="wrap_content" 
    android:layout_height="match_parent" 
    android:layout_gravity="start" 
    android:fitsSystemWindows="true" 
    app:headerLayout="@layout/nav_header_main" 
    app:menu="@menu/activity_main_drawer" /> 

第二步：初始化觀點

private NavigationView navigationView; 
private DrawerLayout drawer; 

第三步：發送事件的抽屜關閉和打開

ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.openDrawer, R.string.closeDrawer) { 

     @Override 
     public void onDrawerClosed(View drawerView) { 
      // Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank 
      super.onDrawerClosed(drawerView); 
     } 

     @Override 
     public void onDrawerOpened(View drawerView) { 
      // Code here will be triggered once the drawer open as we dont want anything to happen so we leave this blank 
      super.onDrawerOpened(drawerView); 
     } 
    }; 

    //Setting the actionbarToggle to drawer layout 
    drawer.setDrawerListener(actionBarDrawerToggle); 

    //calling sync state is necessary or else your hamburger icon wont show up 
    actionBarDrawerToggle.syncState(); 
} 

希望這有助於設置導航抽屜。
