Android NavigationView drawer not closing

Question

Implementing a NavigationView drawer - I am able to generate the drawer and see it, but cannot close it with swiping. Additionally, the NavigationItemSelectedListener does not appear to be set up correctly, as I cannot detect click events on the items.

MainActivity.java

private NavigationView navigationView;
private DrawerLayout navDrawerLayout;
private ListView navDrawerList;
private ArrayList<NavDrawerItem> navDrawerItemList;
private ActionBarDrawerToggle navDrawerToggle;

    private void setupNavDrawer() {
    this.navigationView = (NavigationView) findViewById(R.id.navigation_view);
    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(MenuItem item) {
            Utility.showDebugToast(String.valueOf(item.getItemId()));
            if(item.isChecked()) {
                item.setChecked(false);
            } else {
                item.setChecked(true);
            }
            navDrawerLayout.closeDrawers();
            return true;
        }
    });
    this.navDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    this.navDrawerList = (ListView) findViewById(R.id.left_drawer);
    this.navDrawerItemList = new ArrayList<>();
    this.navDrawerItemList.add(new NavDrawerItem("NAME", NavDrawerItemType.NAME));
    this.navDrawerItemList.add(new NavDrawerItem("Create Mesh", NavDrawerItemType.CREATE_MESH));
    this.navDrawerList.setAdapter(new NavDrawerAdapter(this, R.layout.drawer_item, R.id.drawer_tab_text, this.navDrawerItemList));

    this.navDrawerToggle = new ActionBarDrawerToggle(this, navDrawerLayout, R.string.accept, R.string.accept) {

        @Override
        public void onDrawerClosed(View view) {
            super.onDrawerClosed(view);
        }
        @Override
        public void onDrawerOpened(View view) {
            super.onDrawerOpened(view);
        }
    };

    this.navDrawerLayout.addDrawerListener(navDrawerToggle);
    navDrawerToggle.syncState();
}

Why can't I slide the Drawer in and out?

Answer 1

With regards to the drawer closing behaviour, I expect this is to do with the structure of your activity.xml.

As per the guidance here:

To use a DrawerLayout, position your primary content view as the first child with a width and height of match_parent. Add drawers as child views after the main content view and set the layout_gravity appropriately.

So this is saying that in your case where you have a content section and one drawer, the DrawerLayout should have two children; first the content, then the drawer. In your xml currently, the DrawerLayout only has one child, everything is in the CoordinatorLayout.

Try moving your NavigationView outside of the CoordinatorLayout so your activity looks something like this:

<DrawerLayout>
    <CoordinatorLayout>
        content
    </CoordinatorLayout>

    <NavigationView>
        drawer stuff
    </NavigationView>
</DrawerLayout>
