Android - 无法调整AlertDialog的大小

Question

我正在尝试调整我之前做过的AlertDialog,但是不记得我是怎么做到的.下面是我使用的代码,但它只是工作.是否有人能够指出我做错了什么.

   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);

提前致谢

你应该替换它

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);

同

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

或试试这个

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

先试试并给我反馈
