Menu button´s activity programming
<p>I want to do a button that when I click it does the same what the menu button of the telephone would do.</p>

<p>I know for example that if I use <code>onBackPressed();</code> it does the same that the <kbd>back</kbd> button of the telephone would do.</p>

<p>Anybody knows how to do that for the menu button? </p>

<p>Thank you</p>
