Question

当我在stackoverflow中搜索吐司时，我发现了许多与我的问题有关的东西。但是他们都没有解决我的问题。在我的Android应用程序中，我应该在彼此之后显示许多祝酒词。但是当我尝试这样做时，接下来的吐司等待当前的吐司完成。即使我使用取消吐司，在我看来它永远不会奏效。请给我一个确切的解决方案。谢谢你..

inflater = getLayoutInflater();
    backgForToast=(ViewGroup) findViewById(R.id.toast_layout_root);
    layout = inflater.inflate(R.layout.toastbackground,backgForToast);
    textForToast = (TextView) layout.findViewById(R.id.text);

    textForToast.setText(toastMessage);
    toast.setGravity(Gravity.TOP|Gravity.LEFT, toastX2-90,toastY2-90);
    toast.setView(layout);
    toast.show();

    Handler handler = new Handler();
    long delay = 500;

    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            toast.cancel();
        }
    }, delay);

Answer 1

您需要先使用Toast创建一个Toast.makeText对象，然后才能cancel()。

Answer 2

这是取消DateTime timeUtc = DateTime.UtcNow; try { TimeZoneInfo cstZone = TimeZoneInfo.FindSystemTimeZoneById("Central Standard Time"); DateTime cstTime = TimeZoneInfo.ConvertTimeFromUtc(timeUtc, cstZone); Console.WriteLine("The date and time are {0} {1}.", cstTime, cstZone.IsDaylightSavingTime(cstTime) ? cstZone.DaylightName : cstZone.StandardName); } catch (TimeZoneNotFoundException) { Console.WriteLine("The registry does not define the Central Standard Time zone."); } catch (InvalidTimeZoneException) { Console.WriteLine("Registry data on the Central STandard Time zone has been corrupted."); }：
