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" : {"+
