Answer 1

You can use openOptionsMenu to programmatically open the options menu.

If you have a Button, you can do:

button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        openOptionsMenu();
    }
});

or else set android:onClick="myOnClickMethod" on your Button in xml and then have:

public myOnClickMethod(View v) {
    openOptionsMenu();
}

in your activity.

Warning -- this is completely insufficient in terms of cross-version and <Application /> configuration requirements. It is not this simple once you start considering Honeycomb, ActionBars, ICS, 4.3 bugs, etc. – Peritonitis

@CoryTrese please tell some senarios where this can fail. If possible, giving solution to those problems will be remarkably thankful. – Fulmer

My project is completely on single activity with all fragments supporting version 2.3 onwards, not using android provided action bar, made my own layout header and using it as a action bar. – Fulmer

what happens with the activity when openOptionsMenu() is called? does it stop? does it pause? thx – Sublease

I can say this much: openOptionsMenu() is failing on a Samsung Tab S 10.5 LTE running 5.0.2. It works on my other devices. – Alcoran
