问题描述
我添加两个列表视图在一个滚动视图，因为我的两个列表视图（S）将包含数据，但我现在面临的问题是，当我添加列表视图（S）的滚动视图，它只显示一个项目每个列表视图。
I am adding two list view in one scroll view, as my both listview(s) will contains data, but the problem I am facing is that when I add listview(S) in scroll view, it only shows one item of each list view.
下面是图像，
中的XML code是：
The XML code is :
<ScrollView
android:id="@+id/scrollView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="@+id/layoutFooter7"
android:layout_below="@+id/linArrange" >
<RelativeLayout
android:id="@+id/linListViews"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ListView
android:id="@+id/lstviewUnBlockVenues"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#00000000"
android:divider="#00000000"
android:dividerHeight="0dp"
android:fadeScrollbars="false" >
</ListView>
<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/lstviewUnBlockVenues"
android:background="#ABCDEF"
android:orientation="vertical" >
<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Blocked Venues"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#061218" />
</LinearLayout>
<ListView
android:id="@+id/lstviewBlockedVenues"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/linearLayout1"
android:cacheColorHint="#00000000"
android:divider="#00000000"
android:dividerHeight="0dp"
android:fadeScrollbars="false" >
</ListView>
</RelativeLayout>
</ScrollView>
我要的是滚动视图应该向下滚动，如果列表视图中包含更多的项目，因为在这一刻两个列表视图显示一个项目只有：（
All I want is that scroll view should scroll down if the list view contains more items, as at this moment both list views are displaying one item only :(

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ListView
android:id="@+id/list1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<View
android:layout_width="fill_parent"
android:layout_height="5dp"
android:background="#ff0000" />
<ListView
android:id="@+id/list2"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<View
android:layout_width="fill_parent"
android:layout_height="5dp"
android:background="#ff0000" />
<ListView

android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<View
android:layout_width="fill_parent"
android:layout_height="5dp"
