解決android中list在ScrollView當中只顯示一行的問題

這屬於list在ScrollView當中的適配

package com.ladongjiguang.meikuangwuziyunshu.PublicClass;

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

/**

//解決ListView在ScrollView中只能顯示一行的問題
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的構建代碼中添加：

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

即可
