Hak akses user untuk menu di android studio

Ass, saya ingin membuat hak akses user untuk 1 menu pada aplikasi android saya.. pada php dan di database saat login user sudah ada 1 flag yang dinamakan flag "claim" menandakan bahwa user ini boleh mengakses menu ini atau tidak..bila di database user login ini flag claim nya "Y" maka user boleh masuk ke menu ini, sebaliknya bila flag claim nya "N" user tersebut tidak bisa masuk ke menu tsb. untuk menu nya sendiri sudah ada. tinggal bagaimana cara agar hak akses user nya bisa berjalan.. berikut adalah script di homeactivity.java...dimana menu R.id.nav_claim yg akan di setting privilege nya..
public class HomeActivity extends AppCompatActivity
        implements NavigationView.OnNavigationItemSelectedListener, PolicyFragment.OnFragmentInteractionListener {

    TextView navAgentName, navAgentCode;
    String AgentHolder, AgentNameHolder;
    TextView textMain;
    LinearLayout layoutHome;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        Intent intent = getIntent();
        Bundle extras = intent.getExtras();
        AgentHolder = extras.getString("KodeAgent");
        AgentNameHolder = extras.getString("AgentName");

        /*FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });*/

Saat user berhasil login, simpan status "claim" yang dari database ke sharedPreference android. Lalu di HomeActivity lakukan pengecekan "claim" yang disimpan di sharedPreference tadi, kalau "N" disabled/hidden menu claim agar tidak bisa diakses dan sebaliknya.
