ActionView set to an item in support NavigationView not showing

Question

I\'m using the support NavigationView in my navigation drawer to display menu of items.

Answer 1

I can change the text of the counter easily enough. However, The text view that I use is within a LinearLayout, and it has an android:id as well (I tried this without the LinearLayout without issue):

Given that, I am able to see, access and modify the text view within the main activity using the following :

TextView countText = (TextView)findViewById(R.id.textCounter);

countText.setText("6");

Of course, I'm using a trivial method to calculate the value, just setting it to the value "6", but, I don't know what your counter structure actually looks like, and those are not the main concern of your question.

The issue with your ability to view the counter number remains a mystery. See my questions above and we'll hammer out that element as well.

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

        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();
            }
        });

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.setDrawerListener(toggle);
        toggle.syncState();

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