Android listview里面的相对布局

Question

有人实现ExpandableListView里面布局吗？我试图做到这一点，我有高度问题。我想使它成为“wrap_content”，以便在展开时查看完整展开的View。但不幸的是，对于“wrap_content”参数，我无法实现此结果。有人可以帮忙吗？

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="wrap_content" 
android:layout_height="fill_parent" > 

<ScrollView 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"> 

<RelativeLayout 
    android:layout_width="wrap_content" 
    android:layout_height="fill_parent" > 

<TextView 
    android:id="@+id/user" 
    android:layout_width="match_parent" 
    android:layout_height="100dp" 
    android:layout_alignParentTop="true" 
    android:layout_below="@+id/rl" 
    android:layout_toRightOf="@+id/user" 
    android:paddingLeft="3dp" 
    android:text="Top User" 
    android:textColor="#000000" 
    android:textSize="22dp" /> 

<ExpandableListView 
    android:id="@+id/elvMain" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/user" 
    android:layout_above="@+id/about" > 
</ExpandableListView> 

<TextView 
    android:id="@+id/about" 
    android:layout_width="match_parent" 
    android:layout_height="100dp" 
    android:layout_alignParentBottom="true" 
    android:text="Bottom About" 
    android:textColor="#6f6f6f" 
    android:textSize="24dp" 
    android:textStyle="bold" /> 
</RelativeLayout> 
</ScrollView> 
    </RelativeLayout> 

组一行ExpandableListView：

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

    <TextView android:id="@+id/groupname" 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:textStyle="bold" 
    android:textSize="20dp" 
    android:paddingLeft="40dp" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:minHeight="?android:attr/listPreferredItemHeight" 
    android:textAppearance="?android:attr/textAppearanceLarge" 
    android:background="@drawable/expanded_upper_selector" 
    android:gravity="center_vertical"/> 

子行

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:background="@drawable/ingredients_selector"> 



<TextView android:id="@+id/ingredients_second_layer_text" 
    android:textStyle="bold" 
    android:textSize="20dp" 
    android:paddingLeft="50dp" 
    android:paddingRight="50dp" 
    android:textColor="@color/dark_orange" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:minHeight="?android:attr/listPreferredItemHeight" 
    android:textAppearance="?android:attr/textAppearanceLarge" 
    android:gravity="center_vertical"/>

试试你的XML编辑一些-多少：

Your_XYZ_Ma in_XML ::

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent"

     android:layout_centerVertical="true" 
     android:background="#000000" > 

     <LinearLayout

看看这个链接 - http://about-android.blogspot.in/2010/04/steps-to-implement-expandablelistview.html

这里只添加一个自定义文本。以类似的方式添加第二个。试试这个，如果有任何查询，你可以随意问。希望这会帮助你。
