Android开发实现ScrollView中嵌套两个ListView的方法

import java.io.File;import android.content.Intent;import android.net.Uri;import android.view.View;import android.view.ViewGroup;import android.widget.ListAdapter;import android.widget.ListView;public class ListViewUtility {  // 是一个Scrollview 中 添加两个Listview的显示布局  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++) {//     Global.pos = 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);  }}

signListview.setAdapter(mYinggaoSignListAdapter);appListView.setAdapter(adapter);ListViewUtility.setListViewHeightBasedOnChildren(signListview);ListViewUtility.setListViewHeightBasedOnChildren(appListView);
