Adding items to ActionBar in a Fragment

Question

I'm trying to figure out how to add items to the ActionBar menu through a Fragment. My application's MainActivity is inheriting ActionBarActivity and I want to be able to change the items on the ActionBar based on which Fragment is currently showing.

public class LoginFragment : BaseFragment
{
    //...

    public override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);
        SetHasOptionsMenu(true);
        // this.Activity.MenuInflater.Inflate(Resource.Menu.something, ???);
    }
}

Sure, but I'm having trouble figuring out how to access the objects I need to manipulate. `OnCreateOptionsMenu` for my `MainActivity` requires an argument of `IMenu`. Where does that come from? — Jared Price, Oct 20 '14 at 17:55
you can create a custom function and just make a global refrence in activity and it will be initialize in onCreateMenu — Danial Hussain, Oct 20 '14 at 17:57
you need to simply call that function from anywhere in activity — Danial Hussain, Oct 20 '14 at 17:58

Copied From here

   1. Remove or comment any onOptionsItemSelected() ,onMenuItemSelected() even onPrepareOptionMenu() and leave in Activity onCreateOptionsMenu() only:

    @Override
    public boolean onCreateOptionsMenu(Menu menu){
    MenuInflater inflater=getMenuInflater();
    inflater.inflate(R.layout.menu, menu);
    return true;
    }

In Fragment class, in onCreateView(), put:
```
setHasOptionsMenu(true);
```

In Fragment class add :

@Override
 public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
 super.onCreateOptionsMenu(menu,inflater);      
 }

@Override
 public boolean onOptionsItemSelected(MenuItem item){           
         switch(item.getItemId()){
         case R.id.action_insert:
            //doing stuff
         return true;
         }
         return false;
     }

Tested and worked on Android 4.4

Ahh, I was trying to find the override for onCreateOptionsMenu. I didn't realize it returned void for Fragments. — Jared Price, Oct 20 '14 at 18:13
