Hello!
I tried modifying the code so that a sweeping second hand effect could be achieved, similar to expensive watches like Rolex have. I know that I should animate the second hand, but don't quite know how to implement it.
First I tried setting the delay in:
public void setTime(Calendar calendar) { mCalendar = calendar; invalidate(); if (autoUpdate) { new Handler().postDelayed(new Runnable() { @Override public void run() { setTime(Calendar.getInstance()); } }, 1000); } }
to 250 instead of 1000 and modifying the updateHands() slightly so that second hand would update more often. Obviously 250ms was little bit too much and the second hand jumped weirdly.
I realized that animation is a better idea.
I looked at this example: https://stackoverflow.com/questions/13719890/how-to-make-android-sweeping-second-hand-on-analog-clock
but realized this widget is using canvas instead of ImageView and found out that a good way would be to use Matrix while animating. Something similar to this:

Unfortunately I can't quite get it to work.
Any suggestions or pointers?
