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儲存的是JSON代碼，解析後的資料在LogCat裡輸出     */        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\" : \"加內特\","+            "\"Height\" : \"2.11cm\","+             "\"Age\" : 35"+          "},"+                  //LikeList 就是一個 JSONObject          "\"LikeList\":" +              "{\"List\": " +              "["+                    //這裡也是JSONObject                  "{"+                    "\"Name\" : \"Rose\","+                    "\"Height\" : \"190cm\","+                     "\"Age\" : 23"+                  "},"+                  //這裡也是JSONObject                  "{"+                    "\"Name\" : \"科比\","+                    "\"Height\" : \"198cm\","+                     "\"Age\" : 33"+                  "}"+              "]"+              "}"+          "}";                try {            JSONObject dataJson = new JSONObject(str);            Log.d(TAG, dataJson.getString("日期"));                        JSONObject nbaJson = dataJson.getJSONObject("Like");                    Log.d(TAG, nbaJson.getString("Name"));            Log.d(TAG, nbaJson.getString("Height"));            Log.d(TAG, nbaJson.get("Age").toString());                        JSONObject listJson = dataJson.getJSONObject("LikeList");            JSONArray arrayJson = listJson.getJSONArray("List");                        for(int i=0;i<arrayJson.length();i++) {                                JSONObject tempJson = arrayJson.optJSONObject(i);                                Log.d(TAG, tempJson.getString("Name"));                Log.d(TAG, tempJson.getString("Height"));                Log.d(TAG, tempJson.getString("Age").toString());                }                                } catch (JSONException e) {            System.out.println("Something wrong...");            e.printStackTrace();        }    }}
