Android开发-数组运用-List点击通过数组传递Key-AndroidStudio

解析Json，并添加到List，如何在onClick的时候，把Json的某个key传递出去呢，我利用了数组。如果有更好的办法，请告诉我，谢谢！

/**
 * 数组 用于存放taskId
 * 数组赋值 taskIdArray[i] 在解析Json并list.add时赋值
 * 数组取值 taskIdArray[position] 在onItemClick并data.setTaskId时取值
 */
String[] taskIdArray = new String[100];

/**
 * JSONArray
 * 解析Json中的标题 并设置到 list
 * 以下对应 http://125.208.12.227/appceshi/Api
 */
try {
   JSONArray jsonArray = new JSONArray(result.toString());
   System.out.println("jsonArray.toString() = " + jsonArray.toString());
   System.out.println("jsonArray.length() = " + jsonArray.length());
   for(int i=0;i<jsonArray.length();i++)
   {
      JSONObject jsonObject = jsonArray.getJSONObject(i);
      Log.e("TAG", jsonObject.getString("id"));
      String taskId = jsonObject.getString("id");
      Log.e("TAG", jsonObject.getString("renwu"));
      String renwu = jsonObject.getString("renwu");
      list.add("taskId =  " + taskId + " , renwu = " + renwu);
      taskIdArray[i]=taskId;
   }
   taskAdapter = new TaskAdapter();
   listViewTask.setAdapter(taskAdapter);
} catch (JSONException e) {
   e.printStackTrace();
}

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

   MyData data = new MyData();
   data.setPosition(position);
   data.setTaskId(taskIdArray[position]);
   Intent intent = new Intent();
   intent.putExtra(key, data);
   //用于发送消息给Fragment two
   getTargetFragment().onActivityResult(requestCode, Activity.RESULT_OK, intent);

   mainActivity.showTwoFragment();
}
