我把@DougW的实用程序转换成c#(在Xamarin中使用)。下面的代码对于列表中固定高度的项目很有效，如果只有一些项目比标准项目稍大一点，那么大多数项目都将很好，或者至少是一个良好的开端。

// You will need to put this Utility class into a code file including various
// libraries, I found that I needed at least System, Linq, Android.Views and 
// Android.Widget.
using System;
using System.Linq;
using Android.Views;
using Android.Widget;

namespace UtilityNamespace  // whatever you like, obviously!
{
    public class Utility
    {
        public static void setListViewHeightBasedOnChildren (ListView listView)
        {
            if (listView.Adapter == null) {
                // pre-condition
                return;
            }

            int totalHeight = listView.PaddingTop + listView.PaddingBottom;
            for (int i = 0; i < listView.Count; i++) {
                View listItem = listView.Adapter.GetView (i, null, listView);
                if (listItem.GetType () == typeof(ViewGroup)) {
                    listItem.LayoutParameters = new LinearLayout.LayoutParams (ViewGroup.LayoutParams.MatchParent, ViewGroup.LayoutParams.WrapContent);
                }
                listItem.Measure (0, 0);
                totalHeight += listItem.MeasuredHeight;
            }

            listView.LayoutParameters.Height = totalHeight + (listView.DividerHeight * (listView.Count - 1));
        }
    }
}

谢谢@DougW，当我不得不使用其他人的代码时，这让我摆脱了困境。: -)

不是把listview放在Scrollview里面，而是把其余的内容放在listview和Scrollview的开头之间，作为一个单独的视图，并将该视图设置为listview的头部。所以你最终将只有列表视图负责滚动。

在ScrollView中使用ListView有两个问题。

ListView必须完全展开到它的子节点高度。这个ListView解决这个问题:

public class ListViewExpanded extends ListView
{
    public ListViewExpanded(Context context, AttributeSet attrs)
    {
        super(context, attrs);
        setDividerHeight(0);
    }

    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
    {
        super.onMeasure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST));
    }
}

分隔高度必须为0，在行中使用填充代替。

2- ListView消耗触摸事件，所以ScrollView不能像往常一样滚动。这个ScrollView解决了这个问题:

public class ScrollViewInterceptor extends ScrollView
{
    float startY;

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

    @Override
    public boolean onInterceptTouchEvent(MotionEvent e)
    {
        onTouchEvent(e);
        if (e.getAction() == MotionEvent.ACTION_DOWN) startY = e.getY();
        return (e.getAction() == MotionEvent.ACTION_MOVE) && (Math.abs(startY - e.getY()) > 50);
    }
}

这是我发现的最好的方法!

虽然建议的setListViewHeightBasedOnChildren()方法在大多数情况下都可以工作，但在某些情况下，特别是对于许多项，我注意到最后一个元素不显示。所以我决定模仿一个简单版本的ListView行为，以便重用任何适配器代码，这里是ListView的替代方案:

import android.content.Context;
import android.database.DataSetObserver;
import android.util.AttributeSet;
import android.util.Log;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.ListAdapter;

public class StretchedListView extends LinearLayout {

private final DataSetObserver dataSetObserver;
private ListAdapter adapter;
private OnItemClickListener onItemClickListener;

public StretchedListView(Context context, AttributeSet attrs) {
    super(context, attrs);
    setOrientation(LinearLayout.VERTICAL);
    this.dataSetObserver = new DataSetObserver() {
        @Override
        public void onChanged() {
            syncDataFromAdapter();
            super.onChanged();
        }

        @Override
        public void onInvalidated() {
            syncDataFromAdapter();
            super.onInvalidated();
        }
    };
}

public void setAdapter(ListAdapter adapter) {
    ensureDataSetObserverIsUnregistered();

    this.adapter = adapter;
    if (this.adapter != null) {
        this.adapter.registerDataSetObserver(dataSetObserver);
    }
    syncDataFromAdapter();
}

protected void ensureDataSetObserverIsUnregistered() {
    if (this.adapter != null) {
        this.adapter.unregisterDataSetObserver(dataSetObserver);
    }
}

public Object getItemAtPosition(int position) {
    return adapter != null ? adapter.getItem(position) : null;
}

public void setSelection(int i) {
    getChildAt(i).setSelected(true);
}

public void setOnItemClickListener(OnItemClickListener onItemClickListener) {
    this.onItemClickListener = onItemClickListener;
}

public ListAdapter getAdapter() {
    return adapter;
}

public int getCount() {
    return adapter != null ? adapter.getCount() : 0;
}

private void syncDataFromAdapter() {
    removeAllViews();
    if (adapter != null) {
        int count = adapter.getCount();
        for (int i = 0; i < count; i++) {
            View view = adapter.getView(i, null, this);
            boolean enabled = adapter.isEnabled(i);
            if (enabled) {
                final int position = i;
                final long id = adapter.getItemId(position);
                view.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        if (onItemClickListener != null) {
                            onItemClickListener.onItemClick(null, v, position, id);
                        }
                    }
                });
            }
            addView(view);

        }
    }
}
}

你不应该把ListView放到ScrollView中因为ListView已经是一个ScrollView了。这就像把一个ScrollView放到一个ScrollView中。

你想要完成什么?

它有一个内置的设置。在ScrollView中:

android:fillViewport="true"

在Java中,

mScrollView.setFillViewport(true);
