You can handle it in fragments onAttach
method. Set the visibility of perticular item according to your need.
@Override
public void onAttach(Context context) {
super.onAttach(context);
YourActivity activity = (YourActivity)context;
NavigationView navigationView = (NavigationView) activity.findViewById(R.id.yournavigationviewid);
navigationView.getMenu().findItem(R.id.youritemid).setVisible(false);
}
inside your setNavigationItemSelectedListener where you get the selected menuItem, you can implement the code. Also you require to store the instance of the hidden menu item to make it visible later
MenuItem prevMenuItem;
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
if(prevMenuItem != null) prevMenuItem.setVisible(true) //making visible the previously hidden item.
menuItem.setVisible(false);
prevMenuItem = menuItem //storing the instance of currently hidden item to make it visible later.
return true;
}
});
In your public onNavigationItemSelected(MenuItem item) if you are setting one fragment then automatically drawer will hide. I'm doing like this :
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
toolbar.setTitle(item.toString());
int id = item.getItemId();
if (id == R.id.dashboard) {
fragment = new DashboardFragment();
} else if (id == R.id.manage_users) {
}else{
}
setFragmentLayout(fragment);
return true;
}
Set your fragment according to your requirements.
You can hide the drawer using mDrawerLayout.closeDrawers()
in onNavigationItemSelected
Listener like this:
mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
menuItem.setChecked(true);
switch (menuItem.getItemId()) {
case R.id.navigation_item_shop:
//do your stuffs or attach fragment
mDrawerLayout.closeDrawers();
return true;
default:
return true;
}
}
}
on the fragments overide the onAttach
method. Set the visibility of for items your don't need.
@Override
public void onAttach(Context context) {
super.onAttach(context);
MainActivity activity = (MainActivity)context;
NavigationView navigationView = (NavigationView) activity.findViewById(R.id.navmenu);
// hide the menu items not related to this fragment
Menu m = navigationView.getMenu();
m.findItem(R.id.first).setVisible(false);
m.findItem(R.id.second).setVisible(false);
m.findItem(R.id.therd).setVisible(false);
//and so on
