What is the duration of a Toast LENGTH_LONG and LENGTH_SHORT

Question

I need the exact duration of LENGTH_LONG and LENGTH_SHORT in milliseconds (ms). Also I need to know if the duration of Toast message with LENGTH_LONG will have the same duration in any phone and with any API version.

Does someone know where is the duration defined ?, I mean defined in ms . I know that LENGTH_LONG is some int const with value 1. But I could not find where is the actual duration defined.

Answer 1

Answered here. Like you mentioned Toast.LENGTH_SHORT and Toast.LENGTH_LONG are not in ms but 0 or 1.

The actual durations are:

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

Answer 2

The Toast.LENGTH_SHORT and Toast.LENGTH_LONG are just flags.
You can find here the official android source where these flags are defined:

public class NotificationManagerService extends SystemService {

    static final int LONG_DELAY = PhoneWindowManager.TOAST_WINDOW_TIMEOUT;
    /** Amount of time (in milliseconds) a toast window can be shown. */
    //public static final int TOAST_WINDOW_TIMEOUT = 3500; // 3.5 seconds
    static final int SHORT_DELAY = 2000; // 2 seconds

    private void scheduleDurationReachedLocked(ToastRecord r)
    {
       mHandler.removeCallbacksAndMessages(r);
       Message m = Message.obtain(mHandler, MESSAGE_DURATION_REACHED, r);
       int delay = r.duration == Toast.LENGTH_LONG ? LONG_DELAY : SHORT_DELAY;
       //....
       mHandler.sendMessageDelayed(m, delay);
     }
}

Answer 3

its true that we are not allowed to change the duration of the Toast. But if you are searching for an alternative and you really need to do this with a Toast, then you can try this.

Keep another duplicate toast in the next line

Ex:

Toast.makeText(this, "Hello StackOverFlow", Toast.LENGTH_LONG).show();
Toast.makeText(this, "Hello StackOverFlow", Toast.LENGTH_LONG).show();

The user won't detect any change in transitions between 2 toasts.

Thanks.

Answer 4

You need set the duration override, with setDuration in the action, example:

int s = 6000; // milisegundo    
Snackbar.make(coordinatorLayout, "This is my Snackbar", Snackbar.LENGTH_LONG).setDuration(s)
.show();

Answer 5

I am wondering that why do you not use method setDuration() supported in Toast.java class???

 /**
 * Set how long to show the view for.
 * @see #LENGTH_SHORT
 * @see #LENGTH_LONG
 */
public void setDuration(@Duration int duration) {
    mDuration = duration;
}

Answer 6

Through trial and error I have found Toast.LENGTH_LONG lasts very close to 2500ms

Answer 7

LENGTH_SHORT & LENGTH_LONG are mapped to time interval of 1 Second (1000mS) & 5 Seconds (5000mS) respectively,

To see this you need to dig into AOSP source code of Toast. in Toast class time interval is decided based on the FLAG

mParams.hideTimeoutMilliseconds = mDuration == Toast.LENGTH_LONG ? LONG_DURATION_TIMEOUT : SHORT_DURATION_TIMEOUT;

where

  static final long SHORT_DURATION_TIMEOUT = 5000;
  static final long LONG_DURATION_TIMEOUT = 1000;
