Add a callback in your snackbar like this:

sb.addCallback(new Snackbar.Callback() {

    @Override
    public void onDismissed(Snackbar snackbar, int event) {
        if (event == Snackbar.Callback.DISMISS_EVENT_TIMEOUT) {
            // finish your activity here
        }
    }

    @Override
    public void onShown(Snackbar snackbar) {
        ...
    }
});

Thank you. may i question? in your code, where should sb.show() be located? in onShow()? or.. in front of sb.addCallback? – ybybyb Nov 15 '20 at 18:50
After adding the callback, show the SnackBar like this: `Snackbar sb = Snackbar.make(wc, "SAVE", Snackbar.LENGTH_SHORT).setDuration(3000); sb.addCallback(){}; sb.show();` – Soumik Bhattacharjee Nov 15 '20 at 18:52
