提取從JSON對象中的值到的意圖

Question

目的據我已示出的代碼示例，responseJson返回姓的值。我想從responseJson中獲得該值，因爲我想將它傳遞給下一個活動。任何幫助將不勝感激。

@Override 
     protected void onPostExecute(JSONObject result) { 
      // TODO Auto-generated method stub 
      super.onPostExecute(result); 

      String myResJson; 
      try { 

       myResJson = responseJson.getString("Status"); 
       String test = myResJson; 
       if (test.equals("200")) { 
        Intent intent = new Intent(contxt, ActivityMenu.class); 

        intent.putExtra("FirstName", firstname); 
        contxt.startActivity(intent); 
       } else { 
        Toast.makeText(contxt, 
          "Login Error, invalid Email or Password", Toast.LENGTH_SHORT) 
          .show(); 
       } 
      } catch (JSONException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 

     } 

這是我的responseJson值{"LastName":"A","UserID":"1","Status":"200","FirstName":"P"}

Answer 1

變化

intent.putExtra("FirstName", firstname); 

到

intent.putExtra("FirstName", responseJson.getString("FirstName")); 

OR

firstname=responseJson.getString("FirstName"); 

if(firstname!=null) 
    intent.putExtra("FirstName", firstname);
