不要在scrollview中使用listview。相反，你应该使用NestedScrollView作为父视图，并在....中使用RecyclerView因为它处理了很多滚动问题

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?

这是DougW、Good Guy Greg和Paul的答案组合。我发现当尝试使用自定义列表视图适配器和非标准列表项时，这都是需要的，否则列表视图会导致应用程序崩溃(也会导致Nex的答案崩溃):

public void setListViewHeightBasedOnChildren(ListView listView) {
        ListAdapter listAdapter = listView.getAdapter();
        if (listAdapter == null) {
            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);
    }

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();
}

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;
    }
}

以前这是不可能的。但是随着新的Appcompat库和Design库的发布，这可以实现。

你只需要使用NestedScrollView https://developer.android.com/reference/android/support/v4/widget/NestedScrollView.html

我不知道它将与Listview工作与否，但与RecyclerView工作。

代码片段:

<android.support.v4.widget.NestedScrollView 
android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.v7.widget.RecyclerView
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

</android.support.v4.widget.NestedScrollView>
