在scrollview中使用此自定义列表视图组件。

package com.app.Settings;

import android.content.Context;
import android.util.AttributeSet;
import android.view.ViewGroup;
import android.widget.ListView;

public class ExpandableHeightListView extends ListView
{

boolean expanded = false;

public ExpandableHeightListView(Context context)
{
    super(context);
}

public ExpandableHeightListView(Context context, AttributeSet attrs)
{
    super(context, attrs);
}

public ExpandableHeightListView(Context context, AttributeSet attrs,int defStyle)
{
    super(context, attrs, defStyle);
}

public boolean isExpanded()
{
    return expanded;
}

@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
    // HACK! TAKE THAT ANDROID!
    if (isExpanded())
    {
        // Calculate entire height by providing a very large height hint.
        // But do not use the highest 2 bits of this integer; those are
        // reserved for the MeasureSpec mode.
        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);

        ViewGroup.LayoutParams params = getLayoutParams();
        params.height = getMeasuredHeight();
    }
    else
    {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }
}

public void setExpanded(boolean expanded)
{
    this.expanded = expanded;
}
}

如何使用XML？

 <yourPackageName.ExpandableHeightListView
        android:id="@+id/expandableHeightlist1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"   
        android:cacheColorHint="#00000000"
        android:fadingEdge="none"
        android:focusable="false"
        android:scrollbars="none"
        >
    </yourPackageName.ExpandableHeightGridView>

并设置

yourListView.setExpanded(true);

通过使用此自定义组件，您可以在scrollview中设置多个listview。我正在使用这个自定义组件。

Answer 2

永远不要在listview

中使用两个Scrollview

如果您拥有固定数量的观看次数，请不要尝试使用listview，而是使用LinearLayout。由于listview将有自己的滚动，这也不是一个好的用户体验。
