Question

我在一个滚动视图中添加两个列表视图，因为我的两个列表视图将包含数据，但我面临的问题是当我在滚动视图中添加listview（S）时，它只显示一个项目每个列表视图。

这是图片，

enter image description here

XML代码是：

<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>

我想要的是，如果列表视图包含更多项目，滚动视图应向下滚动，因为此时两个列表视图仅显示一个项目：（

我使用了“arnp”的回答，并在scrollview中使用3 listView制作了示例。它工作正常。

布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    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:id="@+id/list3"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content" />

            <View
                android:layout_width="fill_parent"
                android:layout_height="5dp"
                android:background="#ff0000" />
        </LinearLayout>
    </ScrollView>

</RelativeLayout>

        ListView list1 = (ListView) findViewById(R.id.list1);

        ListView list3 = (ListView) findViewById(R.id.list3);


        String[] items1 = { "Alfa1", "Alfa2", "Alfa3", "Alfa4", "Alfa5", "Alfa6", "Alfa7", "Alfa8", "Alfa9", "Alfa10", "Alfa11", "Alfa12", "Alfa13", "Alfa14", "Alfa15", "Alfa16", "Alfa17"  };

            ViewGroup.LayoutParams params = listView.getLayoutParams();
            params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
            listView.setLayoutParams(params);
            listView.requestLayout();
        }

Answer 2

尝试使用 LinearLayout 和权重。你的问题是wrap_content不会使ListViews填满屏幕的50％。

这样的事情：

    <LinearLayout
        android:id="@+id/linListViews"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:weightSum="2"
        >

        <ListView
            android:id="@+id/lstviewUnBlockVenues"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_weight: 1;
            android:cacheColorHint="#00000000"
            android:divider="#00000000"
            android:dividerHeight="0dp"
            android:fadeScrollbars="false" >

        </ListView>


        <ListView
            android:id="@+id/lstviewBlockedVenues"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_weight="1"
            android:cacheColorHint="#00000000"
            android:divider="#00000000"
            android:dividerHeight="0dp"
            android:fadeScrollbars="false" >

        </ListView>
    </LinearLayout>

Answer 3

最好修改UI。

在Android中将一个滚动小部件放在另一个小部件中确实会产生很多问题。有一种解决方法，但这会让滚动成为用户的痛苦。
