If you look in the Android Developers documentation for EditText (TextBox) and Button, you will see that they are all subclasses of TextView (Label), so technically, Button = TextView.
There might be a Clock solution for this, but when your app gets bigger and bigger, you don't want to check text changed events for 10 times or have 10 Clocks in your app.
