Droid: How to get button id from onClick method described in XML?

Following the dev guide, I can add a method to a button using in the XML. This calls the 'buttonPress' method in my activity. If I apply the same method to multiple buttons, how can I determine the identity of the button that has been clicked?

Use getId() method. It returnes the int id that you can compare to the id from resources.

It is very convenient to use switch statement like this:

public void buttonPress(View v) {
    switch (v.getId()) {
        case R.id.button_one:
            // do something
            break;
        case R.id.button_two:
            // do something else
            break;
        case R.id.button_three:
            // i'm lazy, do nothing
            break;
    }
}
