I'm looking for a way to make the Chronometer in Android (preferably 1.6 and upwards) show 10ths of a second while counting up.
Is it possible to do this? If not, is there a free (and preferably open source) library that does the same? Failing that I'll write my own, but I'd rather use someone else's!
Android's default chronometer widget does not support millisecond formatting.
I have modified the Chronometer widget source code in order to show milliseconds. Download it from github.
Is it possible to do this?
Not really. You could pass a format string that shows tenths of a second, but the Chronometer
itself only updates every second. The update frequency is baked into the code.
If not, is there a free (and preferably open source) library that does the same?
The Chronometer
source is available under the Apache License 2.0, so you can modify it to suit. Find all occurrences of 1000
and change them to 100
, and you're probably most of the way there.
Bear in mind that this Chronometer
can be used in an activity but not an app widget, since customized View
classes are not supported by the app widget framework.
I created an instance of a class that I built inside the Activity
. This new class was an extension of the Android CountDownTimer
class(add the implemented methods)
Here in the constructor you can add the duration in milliseconds and the interval to be 1/10 of a second, that is 100 milliseconds. In the onTick
method, the commands are executed every 1/100th of a second for the given duration. That should work.
