Implementing an option menu in Android Studio

Question

How do I implement an option menu in my android application? I tried code from Android Developer but I get errors. Such as these: Element menu must be declared.

Answer 1

In your java code, add this onCreateOptionsMenu to show optionMenu,

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.option_menu, menu); //your file name
        return super.onCreateOptionsMenu(menu);
    }

Keep your under res\menu\option_menu folder,

Now, if you want to set onOptionsItemSelected i.e onClick event for that ou can use,

@Override
    public boolean onOptionsItemSelected(final MenuItem item) {

        switch (item.getItemId()) {
            case android.R.id.new_game:
                //your code
                // EX : call intent if you want to swich to other activity 
                return true;
            case R.id.help:
                //your code
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }
    }
