Android parsing JSON strings with Gson

There is a protected response<result<t>> parsenetworkresponse (Networkresponse Response) {} function in the volley framework. The JSON string obtained from the server or in the cache is parsed in this function.

New String (Response.data, Httpheaderparser.parsecharset (Response.headers, HTTP. utf_8)    result<T> result = Gsonutil.getresult (jsonstring, Mtypetoken);

We can define a Gsonutil class. It writes some functional functions that Gson and JSON convert to each other. For example, the GetResult function is used. Use this function to get the result<t> of this javabean. That is, the specification returned, which is negotiated by front-end developers and background developers. Now that I get the JavaBean, then I'm going to get the data in the JSON as simple as getting a data from a class.

 public  static  <T> T getresult (String jsondata, Typetoken<t> type) {Gson Gson  = new   Gsonbuilder (). Excludefieldswithoutexposeannotation (). Create ();  return   (T) Gson.fromjson (Jsondata,    Type.GetType ()); }

Result<t> class: For example: (the JSON string returned in the background such as: {"err": "Success", "errno": 1, "rsm{" UserId ":" 1 "," email ":"? "," Password ":"? "," FirstName ":" hu "," LastName ":" ann "," Gender ":" 1 "," Photo ":"/picture/userphoto/ 1422624411423.PNG "," Autograph ":" "," Introduce ":" "," Createtime ":" 4 days ago "}} failed to return {" Err ":" user does not exist ! ", errno": 0} )
