android用jsonReader来解析json

对于这个json:

{  "id" : "3232",  "data" : [{    "data1" : "555",    "data2" : "3243"    },    {     "data1" : "888",     "data2" : "777"    }]  }

我们可以这样来解析:

import java.io.IOException;import java.io.InputStream;import java.io.Reader;import java.io.StringReader;import com.google.gson.stream.JsonReader;import android.app.Activity;import android.content.Context;import android.os.Bundle;public class TestActivity1 extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);parseAssertData();}public void parseAssertData() {InputStream is = 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());parseResponse(response);} catch (IOException ex) {ex.printStackTrace();}}private void parseResponse(Reader response) throws IOException {JsonReader reader = new JsonReader(response);reader.beginObject();while (reader.hasNext()) {String name = reader.nextName();if ("id".equals(name)) {String id = reader.nextString();System.out.println("===id="+id);} else if (name.equals("data")) {reader.beginArray();while (reader.hasNext()) {  reader.beginObject();        String name1;        while (reader.hasNext()) {        name1 = reader.nextName();            if (name1.equals("data1")) {            String s1 = reader.nextString();            System.out.println("===s1="+s1);            } else if (name1.equals("data2")) {            String s2 = reader.nextString();            System.out.println("===s2="+s2);            }  else {                reader.skipValue();            }        }        reader.endObject();}reader.endArray();}else {reader.skipValue();}}reader.endObject();reader.close();}}
