안드로이드 JSONObject, JSONArray

●안드로이드 JSON

- 안드로이드에서는 별도로 라이브러리를 추가할 필요없이 JSONObject, JSONArray 클래스를 사용하면 된다.

●예제

- MainActivity.java

package com.example.exam; import org.json.JSONArray; import org.json.JSONException; import org.json.JSONObject; import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.view.MenuItem; import android.widget.Toast; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main);            //JSON만들기 JSONObject jobj = new JSONObject();         try {  jobj.put("이름", "호랑이");        jobj.put("나이", "10");        jobj.put("직업", "동물"); } catch (JSONException e1) { // TODO Auto-generated catch block e1.printStackTrace(); }         JSONArray maglist = new JSONArray();         maglist.put(jobj);         maglist.put(jobj);         maglist.put(jobj); JSONObject jobj2 = new JSONObject(); try { jobj2.put("arr",maglist); } catch (JSONException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } System.out.println("jobj:"+jobj); System.out.println("maglist:"+maglist); System.out.println("jobj2:"+jobj2); //JSON 해석하기 JSONObject obj; try { obj = new JSONObject(jobj2.toString()); JSONArray array = obj.getJSONArray("arr"); JSONObject dataObj = array.getJSONObject(0); String friendName = dataObj.getString("이름"); String friendAge = dataObj.getString("나이"); System.out.println("friendName:"+friendName); System.out.println("friendAge:"+friendAge); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
