DrawerLayout背景ListView

Question

我的DrawerLayout有以下内容

<?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>

我想为我的ListView提供一个背景图像，上面有一个黑色的视图，具有一些不透明度。对于我的iPhone应用程序来说，这很容易--我只是有一个顶部有一个UIView的UIImageView，它有一个黑色的背景和.4的不透明度，一切都很好用。

在Android系统中有办法做到这一点吗？另外，这个映像也将从我需要的server...so下载，以适应这个约束。

我按照下面的第一个答案试了一下，得到了以下错误：

我在执行时会得到错误：drawerLayout.closeDrawer(listLayout);。listLayout是包含ListView的RelativeLayout。

原来我所要做的就是从我的android设备上删除这个应用程序，然后重建。其他的都起作用了！

您只能在DrawerLayout中放置两个子视图，但可以将ListView放在RelativeLayout中。如下所示：

<?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>

Only two child view in DrawerLayout reference
