Add onOptionsItemSelected calling in Fragment

Question

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //no inspection SimplifiableIfStatement
    if (id == R.id.action_filter) {
        FragmentManager fm = getSupportFragmentManager();
        if (userType.equals("İş Arayan"))
            filterDialogTitle = "İş İlanları Filtre";
        else if (userType.equals("Hizmet Arayan"))
            filterDialogTitle = "Hizmet İlanları Filtre";
        FilterDialogFragment editNameDialogFragment = FilterDialogFragment.newInstance(filterDialogTitle);
        editNameDialogFragment.show(fm, "fragment_edit_name");
        return true;
    }

    return super.onOptionsItemSelected(item);
}

In Fragment you have to call setHasOptionsMenu(true)

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setHasOptionsMenu(true);
    ...
}

Then suppose you have to handle menu_item_to_handle_in_fragment item click

For Fragment class

  @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {

        case R.id.menu_item_to_handle_in_fragment:
            // Do onlick on menu action here
            return true;
        }
    return false;
}

For Activity class

 @Override
        public boolean onOptionsItemSelected(MenuItem item) {
            switch (item.getItemId()) {

            case R.id.menu_item_to_handle_in_fragment:
                return false;
            }
        return false;
    }

what if implementation need to be done in both activity and fragment? — Azlan Jamal, Mar 22 '19 at 10:29
@AzlanJamal feel free to just override this event in both activity and fragment — Roland, Aug 16 '20 at 00:07
`setHasOptionsMenu(true)` also works great in the (kotlin) handler `onViewCreated`. +1 — Roland, Aug 16 '20 at 00:08

You need to add setHasOptionMenu(true) in your onCreate of fragment.
When you add this option the fragment lifecycle will calls the onCreateOptionMenu() and onOptionItemSelected().

Follow this steps:

Add setHasOptionsMenu(true) method in onCreate() of your Fragment.
Override onCreateOptionsMenu(Menu menu, MenuInflater inflater) and onOptionsItemSelected(MenuItem item) methods in your Fragment.
Inside your onOptionsItemSelected(MenuItem item) Activity's method, make sure you return false when the menu item action would be implemented in onOptionsItemSelected(MenuItem item) Fragment's method.

Steps to create Option Menu in fragment

1.

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

2.

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle item selection
    switch (item.getItemId()) {
        case android.R.id.home:
            //call function as per your requirement
            return true;
        default:
            return false;
    }
}

Don't forget to add "setHasOptionsMenu(true);" in onCreate() — MontDeska, Jun 16 '20 at 00:33

Ok, many answers and none of the above shows how to actually call Frarment.

This is the whole example tested and working.

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        //activate menu on the top to show icons or menu
        supportActionBar!!.setDisplayHomeAsUpEnabled(true)


        //this part we need to show back arrow on top so user could use backstack
        setupActionBarWithNavController(findNavController(R.id.fragmentContainer))
        //setupActionBarWithNavController(findNavController(R.id.fragmentContainer))

    }

    override fun onSupportNavigateUp(): Boolean {
        val navController = findNavController(R.id.fragmentContainer)
        return navController.navigateUp() || super.onSupportNavigateUp()
    }


    //show icons in top menu
    override fun onCreateOptionsMenu(menu: Menu?): Boolean {
        //inflate our menu our menu situated in res menu menu.xml so R.menu.menu(our menu)
        menuInflater.inflate(R.menu.menu, menu)
        return true
    }

    //if item in menu selected do ......
    override fun onOptionsItemSelected(item: MenuItem): Boolean {

        val navController = findNavController(R.id.fragmentContainer)
        when (item.itemId) {
            **R.id.iconAbout -> navController.navigate(R.id.aboutFragment)**

        }
        return super.onOptionsItemSelected(item)
    }
}
