listview + timer problem?

moppest

There is a list of numbers in the listview, select a row and press the 'start' button, and it will decrease in seconds according to time.
The same is true for the other rows selected, and multiple rows can be decremented by seconds at the same time.
Select a line and press the 'Stop' button to stop the selected line.

Does the number displayed on your ListView also change in real time with the clock
