Android Support Library Snackbar with indefinite length

The latest version of the Android Support Library (22.2.1), now includes LENGTH_INDEFINITE.

The following will show the Snackbar until it is dismissed or another Snackbar is shown.

Snackbar.make(view, "Your Snackbar", Snackbar.LENGTH_INDEFINITE)        .setAction("Your Action", null).show();

UPDATE: As mentioned this is now possible with the release of Android support library 22.2.1, use the LENGTH_INDEFINITE flag

It is not possible to set an indefinite display of a Snackbar when using the official implementation from the Android Design Support library.

While doing this may violate the Material Design philosophy of a Snackbar, there are 3rd party Snackbar implementations that do allow this. Here is an example:

https://github.com/nispok/snackbar

This project allows the following values for duration of display:

LENGTH_SHORT: 2sLENGTH_LONG: 3.5s (default)LENGTH_INDEFINTE: Indefinite; ideal for persistent errors

Beware that this project is no longer being developed due to the release of the official Snackbar implementation.

I am using com.android.support:appcompat-v7:26.1.0 and Snackbar.LENGTH_INDEFINITE works just as it should be. A sample could be like the following:

private HashMap<Long, Snackbar> mTokenSnackbarMap = new LinkedHashMap<>();private void dropPoint(@NonNull Location location) {    final Long token = SystemClock.elapsedRealtime();    // <submitPoint> is the callback to be executed    // at a time in the future, if the "cancel" button    // of the Snackbar isn't clicked until that time.    Runnable submitPoint = () -> {        Snackbar bar = mTokenSnackbarMap.get(token);        if (bar != null) {            // "cancel" button of the Snackbar wasn't clicked,            // but our time is up. Dismiss the Snackbar.            bar.dismiss();            mTokenSnackbarMap.remove(token);            Log.i(TAG, "dropPoint: dismiss snackbar");        }        mDatabase.add(Point.Factory.create(uid, location));        Log.i(TAG, "dropPoint: addPoint");    };    // The indefinite Snackbar allowing arbitrary cancellation.    Snackbar snackbar = Snackbar.make(mMainView, R.string.point_pending, Snackbar.LENGTH_INDEFINITE)        .setAction(R.string.cancel, (v) -> {                    mTokenSnackbarMap.remove(token);                    mUiHandler.removeCallbacks(submitPoint, token);                    Log.i(TAG, "dropPoint: cancel snackbar");                });    mTokenSnackbarMap.put(token, snackbar);    mUiHandler.postAtTime(submitPoint, token,                SystemClock.uptimeMillis() + Constants.POINT_DELAY_MILLIS);    Log.i(TAG, "dropPoint: postAtTime");    snackbar.show();}
