Add this where you want to Trigger TimePicker::>

int hour,minute;
TimePickerDialog mTimePicker = new TimePickerDialog(mContext, 
    new TimePickerDialog.OnTimeSetListener() {
  @Override
  public void onTimeSet(TimePicker timePicker,int selectedHour, int selectedMinute) {
hour = selectedHour;
    minute = selectedMinute;
 }


}, hour, minute, false);// Yes 24 hour time
mTimePicker.setTitle("Select Time");
hour = c.get(Calendar.HOUR);
minute = c.get(Calendar.MINUTE);
mTimePicker.updateTime(hour, minute);
mTimePicker.show();
