Here's how I did it:

  DatePickerDialog dialog = new DatePickerDialog(this,               mDateSetListener,               year, month, day);    dialog.setButton(DialogInterface.BUTTON_NEGATIVE, getString(R.string.cancel), new DialogInterface.OnClickListener() {     public void onClick(DialogInterface dialog, int which) {        if (which == DialogInterface.BUTTON_NEGATIVE) {           // Do Stuff        }     }   });

If you want to perform a different action depending on whether the user selected a date or not you can use an onDismiss handler. Be sure to set a Boolean (e.g., "isDataSet") to indicate whether the user selected a date or not. Here's an example:

// Date Picker Dialog    public void showDatePickerDialog(View view) {    int year, month, day;    isDataSet = false;  // this is used by the onDismiss handler  // Set initial time period in DatePicker to current month    calendarCurrent = Calendar.getInstance();     month = calendarCurrent.get(Calendar.MONTH);    day =   calendarCurrent.get(Calendar.DAY_OF_MONTH);    year =  calendarCurrent.get(Calendar.YEAR);     DatePickerDialog datePickerDialog = new DatePickerDialog(YourActivity.this, dateSetListener, year, month, day );    datePickerDialog.setOnDismissListener(mOnDismissListener);    datePickerDialog.show();    datePickerDialog_visible=true;  //indicate dialog is up  } // [END showDatePickerDialog]   //onDismiss handler private DialogInterface.OnDismissListener mOnDismissListener =         new DialogInterface.OnDismissListener() {             public void onDismiss(DialogInterface dialog) {                 datePickerDialog_visible=false;  //indicate dialog is cancelled/gone                 if (isDataSet) {  // [IF date was picked                     //do something, date now selected                 } else {                     //do someething else, dialog cancelled or exited                 }                }         };
