将吐司设置为以毫秒为单位的特定时间段:

public void toast(int millisec, String msg) {
    Handler handler = null;
    final Toast[] toasts = new Toast[1];
    for(int i = 0; i < millisec; i+=2000) {
        toasts[0] = Toast.makeText(this, msg, Toast.LENGTH_SHORT);
        toasts[0].show();
        if(handler == null) {
            handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {
                    toasts[0].cancel();
                }
            }, millisec);
        }
    }
}

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。

一个自定义背景和视图的祝酒词对我来说很管用。我在nexus 7平板电脑上测试了它，我注意到在循环过程中没有淡入淡出动画。实现如下:

public static void customToast(Context context, String message, int duration) {

    for (int i = 0; i < duration; i++) {
        Toast toast = new Toast(context);
        toast.setDuration(Toast.LENGTH_LONG);
        toast.setGravity(Gravity.CENTER, 0, 0);
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.toast_layout, null);
        TextView textViewToast = (TextView) view
                .findViewById(R.id.textViewToast);
        textViewToast.setText(message);
        toast.setView(view);
        toast.show();
    }

}

下面是上面代码中使用的自定义textview:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/textViewToast"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/fragment_background"
android:padding="8dp"
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="@color/blue" />

@drawable/fragment_background正在使我的吐司有圆角，就像kitkat版本一样。您还可以在该文件中添加其他视图。任何改进和评论的修改都是鼓励的，因为我计划在我的live应用程序中实现这一点。

  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);

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();
