Get selected menu item's index value in the navigation drawer

Question

I have implemented navigation drawer, it is working fine. The only problem that I have to make selected item to deselect when the navigationdrawer closes. I wonder how could I able to get the index value of selected menu item.

navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
  @Override
  public boolean onNavigationItemSelected(MenuItem menuItem) {
      menuItem.setChecked(false);
   }
)}

Answer 1

One way to do is store menu item ID in variable e.g checkedItemID

navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
  @Override
  public boolean onNavigationItemSelected(MenuItem menuItem) {
      menuItemID=menuItem.getItemId();
   }
)}

Then on implement

mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
            R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close) {

        public void onDrawerClosed(View view) {
            super.onDrawerClosed(view);
            // Do whatever you want here

         navigationView.getMenu().findItem(menuItemID).setChecked(false);
        }

        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
            // Do whatever you want here
        }
    };
// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);

Make a variable position of int datatype. Firstly set its value to 0 and onNavigationItemSelected change its value to menuItem index(like 0 or 1 or 2 and so on).Now this position will provide you the index of selected menuItem.

int position = 0;
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
    @Override
    public boolean onNavigationItemSelected(MenuItem menuItem) {
        switch (menuItem.getItemId()) {
           case R.id.first:
                position = 0;
                break;
           case R.id.second:
                position = 1;
                break;
           case R.id.third:
                position = 2;
                break;
        }
        return true;
    }
});
