How to dismiss a Snackbar using it's own Action button?

Question

Android design support library now includes support for Snackbar.

I\'ve used the following code to create one:

Snackbar.make(findViewById(R.id.root_l

Snackbar (from 'com.android.support:design:23.2.1') support many types of dismiss action. You can create a simple filter by using event, such as in this example:

Snackbar.make(view, wornMessage, Snackbar.LENGTH_LONG).setActionTextColor(context.getResources().getColor(R.color.primary))
    .setCallback(new Snackbar.Callback() {
        @Override
        public void onShown(Snackbar snackbar) {
            super.onShown(snackbar);
        // when snackbar is showing
        }

        @Override
        public void onDismissed(Snackbar snackbar, int event) {
            super.onDismissed(snackbar, event);
            if (event != DISMISS_EVENT_ACTION) {
               //will be true if user not click on Action button (for example: manual dismiss, dismiss by swipe
            }
        }
    })
    .setAction("Undo, view1 -> {
        // if user click on Action button
}).show();

Snackbar's dismiss types:

/** Indicates that the Snackbar was dismissed via a swipe.*/
public static final int DISMISS_EVENT_SWIPE = 0;
/** Indicates that the Snackbar was dismissed via an action click.*/
public static final int DISMISS_EVENT_ACTION = 1;
/** Indicates that the Snackbar was dismissed via a timeout.*/
public static final int DISMISS_EVENT_TIMEOUT = 2;
/** Indicates that the Snackbar was dismissed via a call to {@link #dismiss()}.*/
public static final int DISMISS_EVENT_MANUAL = 3;
/** Indicates that the Snackbar was dismissed from a new Snackbar being shown.*/
public static final int DISMISS_EVENT_CONSECUTIVE = 4;

P.S. In sample code used lambda expressions (by RetroLambda)
