Question

美好的一天。我正在开发一个Android应用程序，可以使用一些帮助。

我正在尝试找出在Google地图中搜索特定位置的正确语法。 IE，我位于（lat，lng），想找到所有名为＆＃34; Walmart＆＃34;的商店/商店。靠近那些坐标。

我做了一些研究，似乎有多人建议使用＆＃34; Google Places＆＃34;，但由于Google地图最近发生了巨大变化，我不确定它是否已被弃用。

根据建议更新了代码：

@SuppressWarnings("deprecation")
public double[] searchForStuff(){
    final String searchString = "Starbucks";

    final double[] placeLocations = new double[2];



    Thread backgroundThread = new Thread (new Runnable(){
        public void run(){
            try{

                final URL url = new URL("http://maps.googleapis.com/maps/api/geocode/json?address="
                        + URLEncoder.encode(searchString) + "&sensor=true");

                URLConnection conn = url.openConnection();
                InputStreamReader streamReader = new InputStreamReader(conn.getInputStream());

                BufferedReader br = new BufferedReader(streamReader);
                StringBuilder sb = new StringBuilder();
                String line = null;
                while ((line = br.readLine()) != null) {
                    sb.append(line);
                    sb.append("\n");
                }
                br.close();

                JSONObject mainObject = new JSONObject(sb.toString());
                JSONObject result = mainObject.getJSONArray("results").getJSONObject(0); // Array of location objects
                JSONObject geometry = result.getJSONObject("geometry");
                JSONObject location = geometry.getJSONObject("location");

                double latitude = location.getDouble("lat");
                double longitude = location.getDouble("lng");

                placeLocations[0] = latitude;
                placeLocations[1] = longitude;


            } catch (IOException e) {
                String error = e.toString();
            } catch (Exception e){
                String error = e.toString();
            }

        }   
    });// 


    backgroundThread.start();

    Toast.makeText(getActivity(), "Is this working? " + placeLocations[0], Toast.LENGTH_LONG); //Nope :(
    return placeLocations;



}

仍然有错误

尝试这种方式：

        URL url = new URL("http://maps.googleapis.com/maps/api/geocode/json?address="
                + URLEncoder.encode(address) + "&sensor=true");
        // address is a string variable, "Walmart" for example

        URLConnection conn = url.openConnection();
        InputStreamReader streamReader = new InputStreamReader(conn.getInputStream());

        BufferedReader br = new BufferedReader(streamReader);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = br.readLine()) != null) {
            sb.append(line);
            sb.append("\n");
        }
        br.close();

        JSONObject mainObject = new JSONObject(sb.toString());
        JSONObject result = mainObject.getJSONArray("results").getJSONObject(0); // Array of location objects
        JSONObject geometry = result.getJSONObject("geometry");
        JSONObject location = geometry.getJSONObject("location");

        double latitude = location.getDouble("lat");
        double longitude = location.getDouble("lng");

名为＆＃34的对象数组;结果＆＃34;是位置列表。
