title: TimePickerDialog cancel button
body: <p>I have an activity - TimePickerActivity - which creates a TimePickerDialog.  I have a onTimeSetListener which responds to the Set button at the end of which it calls finish() and returns to the activity that called the TimePickerActivity.   I want it to finish and return if the Cancel button is clicked but can't find any way to do this.   I have googled and tried out severall suggestions but none of them seem to work.  Any simple way to do this?   </p>
