解决android中list在ScrollView当中只显示一行的问题

这属于list在ScrollView当中的适配

package com.ladongjiguang.meikuangwuziyunshu.PublicClass;

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

/**

//解决ListView在ScrollView中只能显示一行的问题
public class Utility {
public static void setListViewHeightBasedOnChildren(ListView listView) {

ListAdapter listAdapter = listView.getAdapter();

if (listAdapter == null) {

// pre-condition

return;

}

int totalHeight = 0;

for (int i = 0; i < listAdapter.getCount(); i++) {

View listItem = listAdapter.getView(i, null, listView);

listItem.measure(0, 0);

totalHeight += listItem.getMeasuredHeight();

}

ViewGroup.LayoutParams params = listView.getLayoutParams();

params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));

listView.setLayoutParams(params);

}

}


用法：
在list的构建代码中添加：

//获得ListView的高度
Utility.setListViewHeightBasedOnChildren(list);

即可
