@Override
    public void onClick(View v) {

        if (v == btnAtGlanceBack) {
            Intent backIntent = new Intent(this, Dashboard.class);
            startActivity(backIntent);

        } else if (v == btnAtGlanceLogOut) {
            Intent logoutIntent = new Intent(this, GlobalScholarLogin.class);
            logoutIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(logoutIntent);

        }
    }
