Timer Accuracy & Reliability

Question

I need a timer that will execute a piece of code that updates my UI at certain intervals. However, I also need to know when exact 1 second intervals occur. I have heard that if the interval is set to be too frequent, it will sometimes be skipped. My basic goal is to update a clock-like UI, so I need to update the visual circular part at <1 second intervals, but only update the digital part at 1 second intervals. Of the different timers I have been able to find, none of them had a property for the amount of time elapsed since starting it. What would you suggest?

Hello,​

Welcome to our Microsoft Q&A platform!

My basic goal is to update a clock-like UI

Hi, njsokalski. To display a clock-like UI, try using TextClock control. It supports to display the time value and update the value automatically.

   <TextClock  
       android:id="@+id/clock"  
       android:layout_width="match_parent"  
       android:layout_height="wrap_content"  
       android:gravity="center_horizontal"  
       android:format12Hour="dd:MM:yyyy--hh:mm:ss a"/>  

none of them had a property for the amount of time elapsed since starting it. What would you suggest

You could create a parameter to record the start point and then get current time to caculate the the amount of time elapsed.

Best Regards,
