Make a dynamically following textview with counter

So, i am making a stopwatch app right now. And now i need to make a text view that follow the tick of the stopwatch

The conditions are: stopwatch already exist, there are two textviews (one for second and one for minute) that will follow the numbers of the stopwatch that is counting and checkboxes that corresponds with the visibility of the textview. The textview is used as minute view and second view (literally) of the stopwatch What should i do so that everytime the textview is shown, it will follow the digit of stopwatch as it goes on?
