导航抽屉内扩展列表视图没有达到系统栏的底部 [英] Expandable Listview inside Navigation Drawer not reach bottom of system bar

问题描述

我想实现展开列表视图导航抽屉里像下面的图片。有4个组，每个组有许多儿童。我的问题是，可扩展列表视图的高度为短。我怎样才能让这个高度达到系统栏的底部就像使用列表视图与4组数据的正常航行抽屉里？

I am trying to implement 'Expandable Listview' inside Navigation Drawer like in the picture below. There are 4 groups, and each group has many children. My problem is, the height of expandable listview is "short". How can I make this height reach the bottom of system bar just like a normal navigation drawer using listview with 4 groups data?

这是我的main_activity.xml：

this is my main_activity.xml :

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

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

<ExpandableListView
    android:id="@+id/left_drawer"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:choiceMode="singleChoice"
    android:divider="@android:color/black"
    android:dividerHeight="1dp" 
    android:indicatorRight="430dp"/>

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

任何帮助将大大AP preciated。

推荐答案

设置背景色为 ExpandableListView 以及

<ExpandableListView
android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/black"
android:dividerHeight="1dp" 
android:indicatorRight="430dp"
android:background="#fff"/>

我觉得你的扩展列表是match_parent但它没有背景，只有4项。

I think your expandable list is match_parent but it has no background and only 4 items.
