Android: How to add listener to hardware menu button?

Question

I'm currently trying to add a click listener to the menu hardware button. Currently I'm just putting my onclick logic into the onCreatePanelMenu-method and return false. But that just feels wrong.

Is there a more clean way?

The code currently looks like that:

@Override public boolean onCreatePanelMenu(int featureId, Menu menu) {     Toast.makeText(this, "HALLO!", Toast.LENGTH_SHORT).show();     return false; }
