在为android中的DrawerLayout添加Relativelayout后，为什么我的应用程序强制关闭？

标签： android listview relativelayout drawerlayout

我正在尝试为滑块Listview获取阴影效果。我试图将一个RelativeLayout与阴影图像放在ListView下面。我已经在我的xml文件中完成了以下操作但是因为以下错误而关闭了force。请指导我一步一步做什么以及我哪里出错。

我的xml文件

<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"

android:layout_height="match_parent">


<FrameLayout
    android:id="@+id/content_frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent" 


   >




</FrameLayout>


     <FrameLayout
        android:layout_width="250dp"
        android:layout_height="match_parent"
         > 

   <ListView
    android:id="@+id/left_drawer"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:choiceMode="singleChoice"
    android:divider="#656565"
    android:dividerHeight="0.01dp"
     android:fadingEdgeLength="10dp"

    android:background="@color/list_background"
    android:listSelector="@drawable/list_selector"
   />

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

显然你在FrameLayout里面有你的listView。如果你删除它，一切都会好起来的。

否则在xml

中将id设置为2nd frameLayout 
android:id="@+id/framelayout"

然后获取FrameLayout

的实例 
FrameLayout frameLayout = (LinearLayout) findViewById(R.id.frameLayout);

将FrameLayout的实例传递给mDrawerLayout.closeDrawer(frameLayout);。

希望这能解决问题。
