  @PubuduGayan
  first I'm working with time picker and timer together and I want to store the time I selected and start timer , when the time equals 00:00:00 I want to set the time I selected before etc..

  here my code

  Main Activity.cs ;-

  Timer _timer; int _countsecond = 1; TextView textview; int seconds = 59; int minutes; int hours; string _t; Button _btnpick; Button _start;
  `textview = FindViewById(Resource.Id.tvTimeCount);
  _btnpick = FindViewById(Resource.Id.pickTime);
  _start = FindViewById(Resource.Id.startcount);
  _start.Click += delegate
  {
  _timer = new Timer();
  _timer.Interval = 1000;
  _timer.Elapsed += _timer_Elapsed;
  _timer.Enabled = true;
  _timer.Start();
  };
  _btnpick.Click += delegate
  {
  TimePickerDialog _tp = new TimePickerDialog(this, TimePickerCallback, hours, minutes, true);
  _tp.Show();
  };

          hours = DateTime.Now.Hour;
          minutes = DateTime.Now.Minute;`
  

  private void _timer_Elapsed(object sender, ElapsedEventArgs e) { CountDownTimer(); }

  private void UpdateTime() { _t = string.Format("{0}:{1}:{2}", hours, minutes, seconds.ToString().PadLeft(2, '0')); textview.Text = _t; }

  ` private void TimePickerCallback(object sender, TimePickerDialog.TimeSetEventArgs e)
  {
  hours = e.HourOfDay;
  minutes = e.Minute;
  UpdateTime();

      }`
  

  `private void CountDownTimer()
  {
  if (seconds != 0)
  {
  RunOnUiThread(() => {seconds--;

                  UpdateTime();
              });
  
          }
          else if (seconds == 0 && minutes != 0)
          {
              RunOnUiThread(() => {minutes = minutes -= 1;
                  seconds = 60;
                  _countsecond--;
                  UpdateTime();
              });
  
          }
          else if (seconds == 0 && minutes == 0 && hours != 0)
          {
              RunOnUiThread(() =>
          {
                  hours = hours -= 1;
              minutes = 59;
              seconds = 60;
              _countsecond--;
                  UpdateTime();
          });
          }
          else if(seconds == 0 && minutes == 0 && hours == 0)
          {
              RunOnUiThread(() =>
              {
                  Toast.MakeText(this, "hello", ToastLength.Short).Show();
                  UpdateTime();
                  textview1.TextChanged += (object sender, Android.Text.TextChangedEventArgs e) =>
                  {
                      textview.Text = e.Text.ToString();
                  };
              });
          }

  i'm sorry in CountDownTimer() the last condition I put textview1.TextChanged += (object sender, Android.Text.TextChangedEventArgs e) =>
  {
  textview.Text = e.Text.ToString();
  };
  it just was try to copy the textview in another textview but field and I removed
