Question

如果我在DrawerLayout里添加三个view

如果我在DrawerLayout里添加三个view，代码如下
<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">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- android:layout_gravity="start" tells DrawerLayout to treat
this as a sliding drawer on the left side for left-to-right
languages and on the right side for right-to-left languages.
The drawer is given a fixed width in dp and extends the full height of
the container. A solid background is used for contrast
with the content view. -->
<ListView
android:id="@+id/left_drawer_1"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
<ListView
android:id="@+id/left_drawer_2"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
</android.support.v4.widget.DrawerLayout>
我想要的是打开抽屉listview1,然后在listview1里面打开listview2，可是打开listview1后，listview1可以打
开listview2，并且点击阴影部分或者按手机的back键可以关闭listview2返回到listview1，但是这时点击阴影部分却不能关闭
listview1而且按back键也没有响应。求大神门解答

可以用一个布局文件比如LinearLayout，但记得要加上android:layout_gravity="start"这个属性，不然会报错。
LinearLayout里面就可以写你想要的东西了。
