Android編程解析Json格式數據的方法

本文實例講述了Android編程解析Json格式數據的方法。分享給大家供大家參考，具體如下：

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代碼，解析後的數據在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();
  }
 }
}

希望本文所述對大家Android程序設計有所幫助。
