Can an Android Toast be longer than Toast.LENGTH_LONG?

Question

If you dig deeper in android code, you can find the lines that clearly indicate, that we cannot change the duration of Toast message.

 NotificationManagerService.scheduleTimeoutLocked() {
    ...
    long delay = immediate ? 0 : (r.duration == Toast.LENGTH_LONG ? LONG_DELAY : SHORT_DELAY);
    }

and default values for duration are

private static final int LONG_DELAY = 3500; // 3.5 seconds
private static final int SHORT_DELAY = 2000; // 2 seconds

The values of LENGTH_SHORT and LENGTH_LONG are 0 and 1. This means they are treated as flags rather than actual durations so I don't think it will be possible to set the duration to anything other than these values.

If you want to display a message to the user for longer, consider a Status Bar Notification. Status Bar Notifications can be programmatically canceled when they are no longer relevant.

You may want to try:

for (int i=0; i < 2; i++)
{
      Toast.makeText(this, "blah", Toast.LENGTH_LONG).show();
}

to double the time. If you specify 3 instead the 2 it will triple the time..etc.

If you want a Toast to persist, I found you can hack your way around it by having a Timer call toast.show() repeatedly (every second or so should do). Calling show() doesn't break anything if the Toast is already showing, but it does refresh the amount of time it stays on the screen.
