DrawerLayout背景的ListView

Question

我已经在我的DrawerLayout如下：

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

<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" 
    android:background="@drawable/background_main"> 

    <!-- Framelayout to display Fragments --> 
    <FrameLayout 
     android:id="@+id/frame_container" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 

    <!-- Listview to display slider menu --> 
    <ListView 
     android:id="@+id/list_slidermenu" 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:layout_gravity="start" 
     android:background="@drawable/background" 
     android:choiceMode="singleChoice" 
     android:divider="@color/transparent" 
     android:dividerHeight="0dp" /> 

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

我想有一个背景图像我ListView用在它上面的黑色认为具有一定的不透明度。对于我的iPhone应用程序来说，这非常简单 - 我只有UIImageView，顶部有UIView，背景为黑色，透明度为.4，一切正常。

有没有办法在Android中做到这一点？此外，这个图像将从服务器上下载...所以我也需要适应这个约束。

我试着按下面的第一个答案，并得到了以下错误：

Process: com.mounzaapp, PID: 17534

     at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1087) 
     at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2148) 

做时，我得到的错误：drawerLayout.closeDrawer(listLayout);。 listLayout是包含ListView的RelativeLayout。

打开了所有我需要做的就是从我的Android设备上删除应用程序，然后重建。一切工作！

您只能在DrawerLayout内放置两个子视图，但您可以将ListView置于RelativeLayout之内。就像这样：

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

<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" 
    android:background="@drawable/background_main"> 

    <!-- Framelayout to display Fragments --> 
    <FrameLayout 
     android:id="@+id/frame_container" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 

    <!-- RelativeLayout to display slider menu --> 
    <RelativeLayout 
     android:id="@+id/drawer_container" 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:layout_gravity="start" 
     android:background="@drawable/background" > 

     <ListView 
      android:id="@+id/list_slidermenu" 
      android:layout_width="wrap_content" 
      android:layout_height="match_parent" 
      android:background="@drawable/background" 
      android:choiceMode="singleChoice" 
      android:divider="@color/transparent" 
      android:dividerHeight="0dp" /> 

     <!-- Whatever view you want inside the RelativeLayout --> 

    </RelativeLayout> 

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