 private void SetFragment(Fragment fragment){
        if(fragment != null) {
            String backStateName = fragment.getClass().getName();
            FragmentManager manager = getSupportFragmentManager();
            boolean fragmentPopped = manager.popBackStackImmediate(backStateName, 0);
            if (!fragmentPopped) {
                FragmentTransaction fragmentTransaction = manager.beginTransaction();
                fragmentTransaction.replace(R.id.frameLayout, fragment, backStateName);
                fragmentTransaction.addToBackStack(backStateName);
                fragmentTransaction.commit();
            }
        }
    }
