Android - 無法調整AlertDialog

Question

我正在嘗試調整AlertDialog的大小，我之前完成了這個操作，但不記得我是如何做到的。以下是我使用的代碼，但它只是工作。有人能夠指出我做錯了什麼。

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(getActivity()); 
    alertDialogBuilder 
      .setMessage(R.string.checkout_journey_selector_popup_title) 
      .setPositiveButton(R.string.checkout_journey_selector_popup_paylater_button, 
        new DialogInterface.OnClickListener() { 
         public void onClick(DialogInterface dialog, int id) { 
          CheckoutHelper.startReservationJourney(getActivity(), 
            collectibleItems); 
         } 
        }) 
      .setNegativeButton(R.string.checkout_journey_selector_popup_paynow_button, 
        new DialogInterface.OnClickListener() { 
         public void onClick(DialogInterface dialog, int id) { 
          CheckoutHelper.startPrepayCollectionJourney(getActivity(), 
            collectibleItems); 
         } 
        }).create().show(); 



    Dialog alert = alertDialogBuilder.create(); 
    WindowManager.LayoutParams lp = new WindowManager.LayoutParams(); 
    lp.copyFrom(alert.getWindow().getAttributes()); 

    lp.height = 100; 
    lp.width = 50; 
    alert.getWindow().setAttributes(lp); 

在此先感謝

Answer 1

此時應更換此

Dialog alert = alertDialogBuilder.create(); 
WindowManager.LayoutParams lp = new WindowManager.LayoutParams(); 
lp.copyFrom(alert.getWindow().getAttributes()); 
lp.height = 100; 
lp.width = 50; 
alert.getWindow().setAttributes(lp); 

隨着

WindowManager.LayoutParams lp = new WindowManager.LayoutParams(); 
lp.copyFrom(alertDialogBuilder.getWindow().getAttributes()); 
lp.height = 100; 
lp.width = 50; 
alertDialogBuilder.getWindow().setAttributes(lp); 

或者試試這個

alertDialog.getWindow().setLayout(600, 400); after alertDialog.show(); 

先嚐試，並給我反饋

Answer 2

做這樣

代替alert.getWindow().setAttributes(lp);
