    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
            case R.id.button_two:
                // do something else
            case R.id.button_three:
                // i'm lazy, do nothing
