Android reusable button wiring

Prior to android 1.6, button wiring in android was a process of building out your event listeners and wiring programmatically.  1.6 introduced declarative button wiring in the xml for the ui.

Earlier on, I was trying to build something that loosely resembled the phone dialer but of course NOT the phone dialer. About 15 buttons each having the differentiation from one another nothing more than having a value of a diff number.

I quickly got frustrated writing switch cases and if's for something that was simply taking the value and passing it directly on. I instead I realized I could do the following...

...

And for my click handler...

public void dialerButtonClick(View target) {
doSomethingWithButtonClick(Integer.parseInt(target.getTag().toString()));
}

Is this going to make sense in every case? No... probably not. getTag almost definitely is more of a hit, than simply comparing R.id's, but it seemed to work pretty good for what I wanted it for.

Until next time.
