請張貼一些代碼。 – 2014-11-21 13:10:42

pDialog = new ProgressDialog(QR.this); pDialog.setMessage("Loading. Please wait..."); pDialog.setIndeterminate(false); pDialog.setCancelable(false); 把它放在onCreate方法和簡單的調用pDialog.show（）在Preexecute和pDialog.dismiss（）onPostExecute（），並沒有必要改變OnStop（）

我改變了建議的代碼，但我仍然有同樣的錯誤 – miman 2014-11-21 13:46:29
