This is a small example of learning the chronometer control. paste your own code and communicate with you.
Effect:
Implementation ideas:
Use the chronometer control to operate the meter. Set the initial time by setting setbase (long base), and then add a setonchronometerticklistener (chronometer. onchronometerticklistener L) event to determine whether the time has arrived, and then call its stop () method to stop timing.
Implementation Code:
Main.
Let me talk about myself first, a small programmer in a second-tier city (mainly outsourcing) who has been working for many years and earned a monthly income of 5-6 K.
