实现android上解析Json格式数据功能，该源码转载于安卓教程网的，http://android.662p.com ，个人感觉还不错的，大家可以看看一下吧。

package com.practice.json;



import org.json.JSONArray;

import org.json.JSONException;

import org.json.JSONObject;



import android.app.Activity;

import android.os.Bundle;

import android.util.Log;



public class JsonDemo extends Activity {

    /*

     * 解析JSON的例子，str保存的是JSON代码，解析后的数据在LogCat里输出 

    */

        

        String TAG = "Json message";

        

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        detectJSON();

    }

    

    private void detectJSON() {

            String str = "{"+

            

                  "\"日期\" : \"2011-06-06\","+



                  //Like 是 JSONObject

                  "\"Like\" : {"+

                    "\"Name\" : \"加内特\","+

                  "},"+
