<ExpandableListView
     android:id="@+id/expandableListView1"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:layout_weight="1" >
 </ExpandableListView>

和组的自定义布局

<LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:paddingBottom="5dip"
        android:paddingTop="5dip"
        android:tag="tank" >

        <TextView
            android:id="@+id/textView1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:paddingLeft="6dip"
            android:text="123" />

        <TextView
            android:id="@+id/textView2"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="1000" />
    </LinearLayout>

和 listView 的自定义布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >

<TextView
    android:id="@+id/text1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center_horizontal"
    android:layout_weight="1"
    android:text="TextView" />

<TextView
    android:id="@+id/text2"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:text="TextView" />

如何使用扩展 BaseExpandableListAdapter 的自定义类来填充它？

public class ExpandableListAdapter extends BaseExpandableListAdapter{

@Override
public Object getChild(int groupPosition, int childPosition) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public long getChildId(int groupPosition, int childPosition) {
    // TODO Auto-generated method stub
    return 0;
}

@Override
public View getChildView(int groupPosition, int childPosition,
        boolean isLastChild, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public int getChildrenCount(int groupPosition) {
    // TODO Auto-generated method stub
    return 0;
}

@Override
public Object getGroup(int groupPosition) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public int getGroupCount() {
    // TODO Auto-generated method stub
    return 0;
}

@Override
public long getGroupId(int groupPosition) {
    // TODO Auto-generated method stub
    return 0;
}

@Override
public View getGroupView(int groupPosition, boolean isExpanded,
        View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public boolean hasStableIds() {
    // TODO Auto-generated method stub
    return false;
}

@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
    // TODO Auto-generated method stub
    return false;
}}

用于LayoutInflater膨胀并返回您想要的组getGroupView()布局和您想要的孩子布局getChildView()。
