如何關閉後這個進程對話框中執行的Android

我做了一個自定義進度對話框，我婉關閉它在我的postExecute方法，我下面試過，但我不知道怎麼打發它。我已經嘗試如下，誰能請告訴我，我怎麼能關閉那些定製對話框如何關閉後這個進程對話框中執行的Android

CAQNùTELL哪裏PRE在程序Execute方法?? –

您已評論pdialog.show（）; –

所以如何將ü駁回後上時pdialog.show（）已經執行評論???你可以解釋嗎？ –

它很容易嘗試： pDialog.dismiss（）;

請看到我的編輯的代碼......它是一種對自定義對話框，我想dismis它onPostExecute（）方法 –

STEP 1

申報進度上面的對話框上創建

私人ProgressDialog pDialog;

STEP 2

定義preExecute方法

protected void onPreExecute() { 
    super.onPreExecute(); 
    pDialog = new ProgressDialog(context); 
    pDialog.setTitle("Please wait"); 
    pDialog.setMessage("Processing..."); 
    pDialog.setIndeterminate(false); 
    pDialog.setCancelable(true); 
    pDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); 


    pDialog.setButton(DialogInterface.BUTTON_NEGATIVE, "Cancel", new DialogInterface.OnClickListener() { 
     @Override 
     public void onClick(DialogInterface dialog, int which) { 
      dialog.dismiss(); 
     } 
    }); 

    pDialog.show(); 
}

步驟3

//Your back ground task as it is

步驟4

地址postExecute方法

protected void onPostExecute() 

     { 
    pDialog.dismiss(); 

    }

我想要一個簡單的對話框，你給的代碼給了我異常 –

據只有簡單的你發現它複雜嗎？ –

你需要就叫dismiss()方法ProgressDialog。像

protected void onPostExecute(){ 

    pDialog.dismiss(); 

}

你有progressBar變量保存在您的佈局進度條的引用。要隱藏它，叫

progressBar.setVisibility(View.GONE);

的RelativeLayout你放置在ProgressBar是不必要的。還要考慮包括ProgressBar靜態的佈局，只是它的可見性設置爲必要VISIBLE/GONE。
