OnCreateOptionsMenu() not called in Fragment

I have an app which got one activity with 2 fragments placed horizontally.

In my activity I inflated menu using onCreateOptionsMenu() using which I am able to display actionbar options menu. But when I try to update the action bar menu items from one of my fragment, the onCreateoptionsmenu() is not called. So, I'm not able to update the action bar options menu.

The code in my activity is as below:

myActivity.java

package com.andr.androidtablelist;

import java.io.IOException;

import android.app.ActionBar;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.widget.Toast;

import com.andr.fragments.ListLeftFragment;
import com.andr.utils.DBHelper;

      public class TabletActivity extends Activity {
    ActionBar actionBar = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        DBHelper dbhelper;
        dbhelper = new DBHelper(this);
        try {
            dbhelper.createDatabase();
        } catch (IOException ex) {
            ex.printStackTrace();
        }
        setContentView(R.layout.activity_tablet);
        actionBar = getActionBar();
        actionBar.setDisplayHomeAsUpEnabled(false);
        getFragmentManager().beginTransaction()
                .replace(R.id.master, ListLeftFragment.newInstance()).commit();
    }

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

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case android.R.id.home:
            Toast.makeText(
                    getApplicationContext(),
                    "Back Stack Count::"
                            + getFragmentManager().getBackStackEntryCount(),
                    Toast.LENGTH_LONG).show();
            if (getFragmentManager().getBackStackEntryCount() == 1) {
                actionBar.setDisplayHomeAsUpEnabled(false);
            }
            if (getFragmentManager().getBackStackEntryCount() > 1) {
                getFragmentManager().popBackStack();

            }
            return true;

        }
        return super.onOptionsItemSelected(item);
    }

}

In your fragment's onCreateView() method, you need to call setHasOptionsMenu(true) to tell the host activity that your fragment has menu options that it wants to add.


If you are using a theme that does not support ActionBar, then OnCreateOptionsMenu() will not be called automatically, even you wrote all Java codes properly.

You can open AndroidManifest.xml, change the value of android:theme to "@android:style/Theme.Holo.Light.DarkActionBar", or any other themes that support ActionBar.


this worked for me

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    setHasOptionsMenu(true);
    View view = inflater.inflate(R.layout.sample, null);
}
