android - 如何在 Android 中访问 Google Places API？

Question

我正在开发一个使用 google places API 的应用程序。

我为我的应用程序获得了 API key ，但问题是我从服务器得到的响应是 ZERO_RESULTS。

这是我使用 DefaultHttpClient 建立 http 连接的代码。谁能告诉我问题出在哪里？请帮助我被困在这里。

public class Splash extends Activity{
     private  String keystring="";
     //This is my request url 
    String requesturl="https://maps.googleapis.com/maps/api/place/search/json?" + 
      "location=17.739290150000002,83.3071201&radius=6000&" +
      "types=hospital&sensor=false&key=";
     private static byte[] key; 
     String signaturegot;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
          /*
            Here I am using default http client to establish 
            the connection for the request url
           */
           
            HttpClient client=new DefaultHttpClient();
            StringBuilder builder=new StringBuilder(requesturl);
            builder.append(URLEncoder.encode(keystring));
            HttpPost post=new HttpPost(requesturl);
            try {
                HttpResponse response=client.execute(post);
                HttpEntity entity=response.getEntity();
                if (entity != null) {
                    InputStream is = entity.getContent();
                    String val = StaticUtils.convertStreamToString(is);
                Log.e("",val);
                }
            } catch (ClientProtocolException e) {   
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
    }



Here is the response from the server
{
   "html_attributions" : [],
   "results" : [],
   "status" : "ZERO_RESULTS"
}

Answer 1

由于一些奇怪的原因，对于印度的位置，使用 names 而不是 types

https://maps.googleapis.com/maps/api/place/search/xml?&location=17.739290150000002,83.3071201&radius=6000&names=hospital&sensor=true&key=yourkeyhere

对于电话号码，您必须使用从上述 URL 获得的引用字符串请求详细信息:

https://maps.googleapis.com/maps/api/place/details/json?&reference=usethereferencestringfromtheaboveurl&sensor=true&key=yourkeyhere

输出将包含:

"formatted_phone_number" : "0891 123 0101",
      "geometry" : {
         "location" : {
            "lat" : 17.7060120,
            "lng" : 83.3104410
         }
      },
