Options menu in an Android application

Question

I want to open up the options menu by clicking on my own created button; is this possible?

Answer 1

If you don't want to use the button of the phone, you have to do the following :

define a listener on your button:

openMenuButton = (Button) findViewById(R.id.yourButton);
    openMenuButton .setOnClickListener(this);

and then in the method onClick(), add :

openOptionsMenu()

Answer 2

Use the openOptionsMenu() method of your Activity to open the Menu programatically.

Still, what Nikola said is right - you'd be better conforming with Android's guidelines.
