Question

I want a menu (the one that is triggered by the Menu button on the device) to work from a click on a normal button (an on screen one, of course)..
in a way to “replace” the Menu button on the device on one that is on screen.

Any ideas?

Answer 1

Easily

public void onClick(View v){
    openOptionsMenu(); 
}

Then to override the menu buttons behavior (this is not really reccomended) you can do something like this

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ( keyCode == KeyEvent.KEYCODE_MENU ) {
        Log.d(TAG, "MENU pressed");
        return false;
    }
    return super.onKeyDown(keyCode, event);
}
