型的org.json.JSONObject不能转换到JSONArray

解决方案

试试这样

 的JSONObject对象=新的JSONObject的（结果）;
JSONArray Jarray = object.getJSONArray（接触）;

的for（int i = 0; I＆LT; Jarray.length（）;我++）{
   的JSONObject Jasonobject = Jarray.getJSONObject（ⅰ）;

When I try in my localhost it work find. this is the JSON that provide by my localhost.
