private Toast mToastToShow;
  public void showToast(View view) {
 // Set the toast and duration
 int toastDurationInMilliSeconds = 10000;
 mToastToShow = Toast.makeText(this, "Hello world, I am a toast.",  Toast.LENGTH_LONG);

 // Set the countdown to display the toast
 CountDownTimer toastCountDown;
 toastCountDown = new CountDownTimer(toastDurationInMilliSeconds, 1000 /*Tick duration*/) {
  public void onTick(long millisUntilFinished) {
     mToastToShow.show();
  }
  public void onFinish() {
     mToastToShow.cancel();
     }
    };

    // Show the toast and starts the countdown
     mToastToShow.show();
     toastCountDown.start();
      }

我知道我有点晚了，但我取了Regis_AG的答案，并将其包装在一个助手类中，它工作得很好。

public class Toaster {
  private static final int SHORT_TOAST_DURATION = 2000;

  private Toaster() {}

  public static void makeLongToast(String text, long durationInMillis) {
    final Toast t = Toast.makeText(App.context(), text, Toast.LENGTH_SHORT);
    t.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL, 0, 0);

    new CountDownTimer(Math.max(durationInMillis - SHORT_TOAST_DURATION, 1000), 1000) {
      @Override
      public void onFinish() {
        t.show();
      }

      @Override
      public void onTick(long millisUntilFinished) {
        t.show();
      }
    }.start();
  }
}

在你的应用代码中，就像这样做:

    Toaster.makeLongToast("Toasty!", 8000);

简单地使用SuperToast在任何情况下都可以做出优雅的吐司。让你的吐司颜色鲜艳。编辑你的字体颜色和大小。希望这对你来说都是一体的。

不，这里列出的大多数/所有黑客都不再适用于android 9。但有一个更好的解决方案:如果你的消息需要挂着，使用对话框。

(new AlertDialog.Builder(this)).setTitle("Sorry!")
.setMessage("Please let me know by posting a beta comment on the play store .")
.setPositiveButton("OK", null).create().show();

吐司持续时间可以使用专门运行吐司的线程来破解。这是有效的(运行吐司10秒，修改睡眠和ctr到你的喜欢):

final Toast toast = Toast.makeText(this, "Your Message", Toast.LENGTH_LONG);

Thread t = new Thread(){
    public void run(){
          int ctr = 0;
          try{
               while( ctr<10 ){
                    toast.show();
                    sleep(1000);
                    ctr++;
               }
          } catch (Exception e) {
               Log.e("Error", "", e);
          }
     }
 };
 t.start();

  private Toast mToastToShow;
  public void showToast(View view) {
 // Set the toast and duration
 int toastDurationInMilliSeconds = 10000;
 mToastToShow = Toast.makeText(this, "Hello world, I am a toast.",  Toast.LENGTH_LONG);

 // Set the countdown to display the toast
 CountDownTimer toastCountDown;
 toastCountDown = new CountDownTimer(toastDurationInMilliSeconds, 1000 /*Tick duration*/) {
  public void onTick(long millisUntilFinished) {
     mToastToShow.show();
  }
  public void onFinish() {
     mToastToShow.cancel();
     }
    };

    // Show the toast and starts the countdown
     mToastToShow.show();
     toastCountDown.start();
      }
