Android中ListView嵌套进ScrollView时高度很小的解决方案

package com.example.test.util;

import android.view.View;
import android.view.ViewGroup;
import android.view.ViewGroup.LayoutParams;
import android.widget.ListAdapter;
import android.widget.ListView;

public class UtilityUtil {
    /**
     * 手动设置listview的高度
     *
     * @param listView
     * @return void
     * @author Doraemon

     */
    public static 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);
            /**
             * listItem.measure(0,0) will throw a NPE if listItem is a ViewGroup
             * instance
             */
            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();
        // listView.getDividerHeight()获取子项间分隔符占用的高度
        // params.height最后得到整个ListView完整显示需要的高度
        params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
        listView.setLayoutParams(params);
    }

}

直接调用该方法  传入  yourListView   ，即可
