Android - 包含在 Listview 中的 MapView [英] Android - MapView contained within a Listview

问题描述

目前我正在尝试将 MapView 放置在 ListView 中.有没有人在这方面取得过任何成功?甚至有可能吗?这是我的代码:

Currently I am trying to place a MapView within a ListView. Has anyone had any success with this? Is it even possible? Here is my code:

            ListView myList = (ListView) findViewById(android.R.id.list);
        List<Map<String, Object>> groupData = new ArrayList<Map<String, Object>>();

        Map<String, Object> curGroupMap = new HashMap<String, Object>();
        groupData.add(curGroupMap);
        curGroupMap.put("ICON", R.drawable.back_icon);
        curGroupMap.put("NAME","Go Back");
        curGroupMap.put("VALUE","By clicking here");

        Iterator it = data.entrySet().iterator();
        while (it.hasNext()) 
        {
            //Get the key name and value for it
            Map.Entry pair = (Map.Entry)it.next();
            String keyName = (String) pair.getKey();
            String value = pair.getValue().toString();

            if (value != null)
            {
                //Add the parents -- aka main categories
                curGroupMap = new HashMap<String, Object>();
                groupData.add(curGroupMap);

                //Push the correct Icon
                if (keyName.equalsIgnoreCase("Phone"))
                    curGroupMap.put("ICON", R.drawable.phone_icon);
                else if (keyName.equalsIgnoreCase("Housing"))
                    curGroupMap.put("ICON", R.drawable.house_icon);
                else if (keyName.equalsIgnoreCase("Website"))
                    curGroupMap.put("ICON", R.drawable.web_icon);
                else if (keyName.equalsIgnoreCase("Area Snapshot"))
                    curGroupMap.put("ICON", R.drawable.camera_icon);
                else if (keyName.equalsIgnoreCase("Overview"))
                    curGroupMap.put("ICON", R.drawable.overview_icon);  
                else if (keyName.equalsIgnoreCase("Location"))
                    curGroupMap.put("ICON", R.drawable.map_icon);
                else
                    curGroupMap.put("ICON", R.drawable.icon);

                //Pop on the Name and Value
                curGroupMap.put("NAME", keyName);
                curGroupMap.put("VALUE", value);
            }
        }

        curGroupMap = new HashMap<String, Object>();
        groupData.add(curGroupMap);
        curGroupMap.put("ICON", R.drawable.back_icon);
        curGroupMap.put("NAME","Go Back");
        curGroupMap.put("VALUE","By clicking here");

        //Set up adapter
        mAdapter = new SimpleAdapter(
                mContext,
                groupData,
                R.layout.exp_list_parent,
                new String[] { "ICON", "NAME", "VALUE" },
                new int[] { R.id.photoAlbumImg, R.id.rowText1, R.id.rowText2  }
        );

        myList.setAdapter(mAdapter); //Bind the adapter to the list 

预先感谢您的帮助！！

推荐答案

在这种情况下，您可以像添加任何其他视图一样将 MapView 添加到列表中.这是关于如何创建一个快速教程自定义列表适配器.但我必须提醒您，MapView 是一个非常沉重的视图，如果您尝试在屏幕上显示一堆视图，您会注意到应用程序运行缓慢！您可以在列表项中添加一个按钮，将用户带到另一个包含更多信息(包括地图)的页面.

In that case you would add the MapView to the list just like you would any other view. Here's a quick tutorial on how to create a custom list adapter. But I have to caution you, a MapView is a pretty heavy view and if you try to get a bunch of them on the screen you're going to notice the app being sluggish! You may just add a button to the list item that takes the user to another page with more information including a map.
