工具欄 - 重力無法找到抽屜式視圖LEFT

我的工具欄上有3個選項卡，有一個問題。它適用於我的應用程序的所有其他頁面，但由於某種原因，當我嘗試點擊此頁面上的菜單時會崩潰。工具欄 - 重力無法找到抽屜式視圖LEFT

以下是錯誤：

java.lang.IllegalArgumentException: No drawer view found with gravity LEFT

下面是佈局的xml：

     <fragment

      app:layout="@layout/fragment_navigation_drawer" /> 




</android.support.design.widget.AppBarLayout> 

</android.support.v4.widget.DrawerLayout>

感謝，希望有人能幫助我！

你不能把DrawerFragment DrawerLayout的子視圖中，您必須提供抽屜佈局或抽屜片段抽屜佈局的子視圖。解決您的問題只需將AppletLayout外部的Fragment。就像這樣：

 <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" 
               xmlns:app="http://schemas.android.com/apk/res-auto" 
               xmlns:tools="http://schemas.android.com/tools" 
               android:id="@+id/main_content" 
               android:layout_width="match_parent" 
               android:layout_height="match_parent" 
               android:fitsSystemWindows="true" 
               > 


    <android.support.v4.widget.DrawerLayout 
     android:id="@+id/drawer_layout" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 

    <android.support.design.widget.AppBarLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:paddingTop="0dp"> 

     <include android:id="@+id/app_bar" 
       layout="@layout/toolbar" /> 


     <android.support.design.widget.TabLayout 
      android:id="@+id/tab_layout" 
      android:layout_width="match_parent" 
      android:layout_height="48dp"/> 

     <android.support.v4.view.ViewPager 
      android:id="@+id/view_pager" 
      android:layout_below="@id/tab_layout" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent"/> 







    </android.support.design.widget.AppBarLayout> 

      <fragment 
       android:name="com.bestworkouts.sheikoworkout.NavigationDrawerFragment" 
       android:id="@+id/fragment_navigation_drawer" 
       tools:layout="@layout/fragment_navigation_drawer" 
       android:layout_width="280dp" 
       android:layout_height="match_parent" 
       android:layout_gravity="start" 
       app:layout="@layout/fragment_navigation_drawer" /> 


    </android.support.v4.widget.DrawerLayout> 
</android.support.design.widget.CoordinatorLayout>

你缺少有CoordinatorLayout結束標記底：</android.support.design.widget.CoordinatorLayout>

但是，請注意，DrawerLayout應該是一個頂級佈局。

從技術文檔：

To use a DrawerLayout, position your primary content view as the first child with a width and height of match_parent. Add drawers as child views after the main content view and set the layout_gravity appropriately. Drawers commonly use match_parent for height with a fixed width.

所以我認爲你不應該把它（DrawerLayout）一CoordinatorLayout內。

Android DrawerLayout - No drawer view found with gravity
