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\","+
                    "\"Height\" : \"2.11cm\","+
                    "\"Age\" : 35"+
                  "},"+

                  //LikeList 就是一个 JSONObject
                  "\"LikeList\":" +
                          "{\"List\": " +
                          "["+
                                    //这里也是JSONObject

                        Log.d(TAG, dataJson.getString("日期"));

                        JSONObject nbaJson = dataJson.getJSONObject("Like");

                        JSONArray arrayJson = listJson.getJSONArray("List");

                        for(int i=0;i<arrayJson.length();i++) {

                                JSONObject tempJson = arrayJson.optJSONObject(i);
