java - Android-无法调整AlertDialog的大小

我正在尝试调整AlertDialog的大小，这是我以前做过的，但记不起我是怎么做的。下面是我使用的代码，但它只是在工作。有人能指出我做错了什么吗？

   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);

提前谢谢

最佳答案

你应该把这个换掉

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);

用

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

或者试试这个

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