ScrollView中的可扩展列表视图有问题。我的应用程序中有此布局:

 <?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ScrollView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true" >

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

    <TextView
        android:id="@+id/carType"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:text=" "
        android:textAppearance="?android:attr/textAppearanceMedium" />

    <TableLayout
        android:id="@+id/infoTable"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/carType"
        android:stretchColumns="*" >

        <TableRow>

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:gravity="right"
                android:paddingBottom="5dp"
                android:paddingRight="5dp"
                android:paddingTop="5dp"
                android:text="@string/tire_replacement"
                android:textStyle="bold" />

            <TextView
                android:id="@+id/tirereplacement"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:clickable="true"
                android:text="@string/add_date" />
        </TableRow>

           //...rows...

    </TableLayout>

    <ExpandableListView
        android:id="@+id/listView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/infoTable" >
    </ExpandableListView>
</RelativeLayout>

看起来像这样:
但我看不到整个可扩展列表视图。只有一个组标题行可见(shloud有两个),如果我展开它,就看不到子项。如果删除android:layout_below="@+id/infoTable,则有整个可展开列表视图:
你知道,哪里会有问题?是吗?
