以下是对@djunod的回答的小修改，我需要使它完美地工作:

public static void setListViewHeightBasedOnChildren(ListView listView)
{
    ListAdapter listAdapter = listView.getAdapter();
    if(listAdapter == null) return;
    if(listAdapter.getCount() <= 1) return;

    int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.AT_MOST);
    int totalHeight = 0;
    View view = null;
    for(int i = 0; i < listAdapter.getCount(); i++)
    {
        view = listAdapter.getView(i, view, listView);
        view.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
        totalHeight += view.getMeasuredHeight();
    }
    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
    listView.setLayoutParams(params);
    listView.requestLayout();
}

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?

这肯定会工作............ 你必须替换你的<ScrollView ></ScrollView>在布局XML文件与这个自定义ScrollView像<com.tmd.utils。VerticalScrollview > </com.tmd.utils。VerticalScrollview >

package com.tmd.utils;

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;
import android.widget.ScrollView;

public class VerticalScrollview extends ScrollView{

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

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

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

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        final int action = ev.getAction();
        switch (action)
        {
            case MotionEvent.ACTION_DOWN:
                    Log.i("VerticalScrollview", "onInterceptTouchEvent: DOWN super false" );
                    super.onTouchEvent(ev);
                    break;

            case MotionEvent.ACTION_MOVE:
                    return false; // redirect MotionEvents to ourself

            case MotionEvent.ACTION_CANCEL:
                    Log.i("VerticalScrollview", "onInterceptTouchEvent: CANCEL super false" );
                    super.onTouchEvent(ev);
                    break;

            case MotionEvent.ACTION_UP:
                    Log.i("VerticalScrollview", "onInterceptTouchEvent: UP super false" );
                    return false;

            default: Log.i("VerticalScrollview", "onInterceptTouchEvent: " + action ); break;
        }

        return false;
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        super.onTouchEvent(ev);
        Log.i("VerticalScrollview", "onTouchEvent. action: " + ev.getAction() );
         return true;
    }
}

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!

我们可以将ListView用作ScrollView，而不是将ListView放在ScrollView中。必须在ListView中的东西可以放到ListView中。在ListView的顶部和底部的其他布局可以通过添加布局到ListView的页眉和页脚。整个ListView会给你滚动的体验。

这是我的解决方案。我对Android平台相当陌生，我确信这有点笨拙，特别是在直接调用.measure和设置LayoutParams的部分。直接使用Height属性，但它是有效的。

你所要做的就是调用Utility.setListViewHeightBasedOnChildren(yourListView)，它将被调整大小，以完全适应其项目的高度。

public class Utility {
    public static void setListViewHeightBasedOnChildren(ListView listView) {
        ListAdapter listAdapter = listView.getAdapter();
        if (listAdapter == null) {
            // pre-condition
            return;
        }

        int totalHeight = listView.getPaddingTop() + listView.getPaddingBottom();

        for (int i = 0; i < listAdapter.getCount(); i++) {
            View listItem = listAdapter.getView(i, null, listView);
            if (listItem instanceof ViewGroup) {
                listItem.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
             }

             listItem.measure(0, 0);
             totalHeight += listItem.getMeasuredHeight();
        }

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