    }

    //Method for the navigation bar screen select
    @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem item) {
        Fragment fragment = null;

        int itemId = item.getItemId();

        //Will navigate to correct activity based on selected destination
        if (itemId == R.id.menu_add) {
            fragment = new AddFragment();
        } else if (itemId == R.id.menu_remove) {
            fragment = new RemoveFragment();
        } else if (itemId == R.id.menu_home) {
            fragment = new HomeFragment();
        } else if (itemId == R.id.menu_search) {
            fragment = new SearchFragment();
        } else if (itemId == R.id.menu_settings) {
            fragment = new SettingsFragment();
        }
        return loadFragment(fragment);
    }

    //Used to load the selected fragment
    private boolean loadFragment(Fragment fragment) {
        //switching fragment
        if (fragment != null) {
            getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,fragment).commit();
            return true;
        }
        return false;
    }

}

我正在努力让活动图标改变颜色。当我选择每一个时它都有效，唯一的问题是我希望主页图标在我启动应用程序时成为活动图标。现在，当应用程序启动时，添加图标是活动的。有没有办法在设计中做到这一点，还是需要以编程方式关闭？
