        super.onCreate(savedInstanceState);

        // Checking for first time launch - before calling setContentView()
        Setpref = new SetPreferences(this);
        if (!Setpref.IsLoggined()) {
            gotoMain();
            finish();
        }

        setContentView(R.layout.activity_home);
        ButterKnife.bind(this);

        mSubscriptions = new CompositeSubscription();
        initSharedPreferences();

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

Answer 1

Update These lines of code works for me.. after update clean and rebuild Project.

  NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);
    navigationView.bringToFront();

Here is a simple solution to address this issue. You can just link your HomeActivity methods to the menu items (whichever you want to). Now just create your methods and go to the menu layout. In the menu layout just add the android:onClick inside the item tag and put the particular method name inside it. And you are done. Let me know if this was useful.
