Android uses Gson to parse JSON

Gson is an object parsing json, very useful, introduce a site http://json.parser.online.fr/can help us see a string is not JSON

For JSON files

{"  id": "3232",  "data": {    "data1": {      "name": "Xiaoming",      "age": "  " "}}}

If you use Gson to parse, define the corresponding class with this JSON node, we use MyData to represent the parsed JSON object, data to represent the object that resolves the data node, DATA1 class to represent the object of the Data1 node

public class MyData {int <strong>id</strong>;D ata <strong>data</strong>;} public class Data {Data1 <strong>data1</strong>;} public class Data1 {String <strong>name</strong>; String <strong>age</strong>;}

Note that the name of the member variable must be the same as the name of the node (bold characters)

We put the JSON file under the assets, and when we parse it, we write:

public void Parseassertdata () {InputStream was = null;try {is = This.getassets (). Open ("Ss.json", context.mode_private); int length = is.available (); byte[] buffer = new Byte[length];is.read (buffer); String temp = new string (buffer); Reader response = new StringReader (temp.tostring ()); Gson Gson = new Gson (); MyData MyData = Gson.fromjson (Response,mydata.class); System.out.println ("===age=" +mydata.data.data1.age); catch (IOException ex) {ex.printstacktrace ();}}

The ability to download this very easy sample (including Gson's jar package) in http://download.csdn.net/detail/baidu_nod/7643643
