What is the duration of a Toast LENGTH_LONG and LENGTH_SHORT
AndroidTimeToastDurationMillisecondsAndroid Problem Overview
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.

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
Solution 2 - Android
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);
}
}

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.

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();

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;
}

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;

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