TimePickerDialog - 15 Minutes Interval

Default TimePickerDialog having 1 minute interval changes, how make this by 15 or 30 minutes.
in a very simple way, just create a customize TimePickerDialog class and override the onTimeChanged method of dialog
see below sample code

public class TimePickerDialogs extends TimePickerDialog{

 public TimePickerDialogs(Context arg0, OnTimeSetListener callBack, int hourOfDay, int minute, boolean is24HourView) {
  super(arg0, callBack, hourOfDay, minute, is24HourView);
  // TODO Auto-generated constructor stub
 }

 @Override
 public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
  // TODO Auto-generated method stub
  //super.onTimeChanged(arg0, arg1, arg2);
  if (mIgnoreEvent)
            return;
        if (minute%TIME_PICKER_INTERVAL!=0){
            int minuteFloor=minute-(minute%TIME_PICKER_INTERVAL);
            minute=minuteFloor + (minute==minuteFloor+1 ? TIME_PICKER_INTERVAL : 0);
            if (minute==60)
                minute=0;
            mIgnoreEvent=true;
            view.setCurrentMinute(minute);
            mIgnoreEvent=false;
        }
 }

 private final int TIME_PICKER_INTERVAL=15;
 private boolean mIgnoreEvent=false;
 
}

and called this class by this line of code in your activity class

new TimePickerDialogs(this, new TimePickerDialog.OnTimeSetListener(){

  @Override
  public void onTimeSet(TimePicker view, int selectedHour, int selectedMinute) {
  // TODO Auto-generated method stub
  StringBuilder output = new StringBuilder().append(selectedHour).append(":").append(selectedMinute);
         System.out.println(output.toString());
                }}, hour, minute, true).show();
