我的版本是Android 2.2的谷歌API 8，我可是从模拟器中运行。我想尝试访问位置长期在这个JSON对象。我得到这个之后，我用

 的InputStream河道= entity.getContent（）;

 JSONObject的myAwway =新的JSONObject（convertStreamToString（河道））;
 

谷歌文档说，它返回一个数组，但与周围的花括号它看起来像一个对象。

我需要访问纬度和经度的位置字段和存储为双打。

香港专业教育学院搜查，但似乎只是寻求帮助与简单的文件。

解决方案

 的JSONObject位置= myAwway.getJSONArray("results").getJSONObject(0).getJSONObject("geometry").getJSONObject("location");
双纬度= location.getDouble（土地增值税）;
双LNG = location.getDouble（LNG）;
 

在'结果'JSONArray可能是数组谷歌文档建议。他们刚刚把它包在一个状态的JSONObject，这样你可以尝试工作，对返回值之前检查状态。

My build is Android 2.2 Google API 8 , Im running from the emulator. I am trying try access Location long in this JSON Object. I get this after I use

 InputStream instream = entity.getContent();

 JSONObject myAwway = new JSONObject(convertStreamToString(instream));

Google docs says it returns an array but with the surrounding curly braces It looks like an object.

I need to access lat and lon in the location field and store as doubles.

Ive searched but only seem to find help with simple files.

         },
         "types" : [ "postal_code" ]
      }
   ],
   "status" : "OK"
}

JSONObject location = myAwway.getJSONArray("results").getJSONObject(0).getJSONObject("geometry").getJSONObject("location");
double lat = location.getDouble("lat");
double lng = location.getDouble("lng");

The 'results' JSONArray is probably the array Google docs suggested. They had just wrapped it up in a JSONObject with a status, so that you could check the status before attempting to work on the returned value.
