Android 动作栏中的图标闪烁

我想为我的应用程序创建一个显示闪烁徽标的操作栏。我想每两秒钟显示一次图像，当图像隐藏时，显示片段标题

toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        //getSupportActionBar().setLogo(R.drawable.logo_nuevo);

       /* getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setDisplayShowTitleEnabled(false);
        getSupportActionBar().setIcon(R.drawable.logo_nuevo); */

        mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);

        drawerToggle = new ActionBarDrawerToggle(this, mDrawer, toolbar, R.string.drawer_open, R.string.drawer_close);

        mDrawer.addDrawerListener(drawerToggle);
        nvDrawer = (NavigationView) findViewById(R.id.nvView);
        nvDrawer.inflateHeaderView(R.layout.nav_header);
        setupDrawerContent(nvDrawer);
