chronometer

What I took some time to work on is a program showing time elapsed, or time remaining, from where the user clicks the start button, much like a stopwatch or a chronometer which measures time until you stop and reset. Other examples of measuring time elapsed are those lap times in racing games and time limits, with milliseconds, in other games. I'm running into some trouble, though, because my own stopwatch is not running at the same rate as actual time. It takes longer than one second for my timer to run one second down or up. The code is right here: (the GUI works perfectly; I'm more

I'm doing this way to save the state and restore it after rotation when the chronometer is running. Android_Chronometer pause When I stop the timer at Xsec and then after Y seconds I change the orientation the chronometer marks X+Y seconds. I'd like to leave the time of a stopped chronometer as it was before rotation, no matter how much time has passed. How should I do? I had a similar question about the Chronometer class and how to survive orientation changes. While there are several useful posts and examples, none that I found addressed the total question. This was a helpful post here

What I want is to measure time with milliseconds, but using Chronometer has the problem that it has no accuracy (its most resolution is seconds) I've seen this: Show miliseconds with Android Chronometer But I haven't been able to make it work. Maybe I should use another Object? Any idea? Ok, this is the easiest way: When you want to start the chrono: StartTime=System.currentTimeMillis(); // I've defined StartTime as a double Then, you just have to do compare current time with StartTime: millis=System.currentTimeMillis()-StartTime; // Millis is a double too // If you'd want seconds, add seconds

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! 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

I've got an issue with starting chronometer from the specific time. There is a Date object I want my chronometer start from: Date d = new Date(); //now, just for example chronometer.setBase(d.getTime()); //long value of d Log.d("Date: " , "d.getTime() time is [" + d.getTime() +"]"); Log.d("Chron: " , "chronometer.getBase() is [" + chronometer.getBase() +"]"); //let's print out elapsedRealtime from official sample Log.d("Chron: " , "SystemClock.elapsedRealtime() is [" + SystemClock.elapsedRealtime() +"]"); Output: 06-02 13:35:23.025: D/Date:(928): d.getTime() time is [1338644123032] 06-02 13:35

I want to pause chronometer and after I click the button I want to continue chromoneter to count... I search but couldn't a function related this.. how can do it? You are gonna need a variable that keeps track on the time that has passed since the Chronometer was started: long timeWhenStopped = 0; Update the value of the variable when you stop the chronometer like this: timeWhenStopped = mChronometer.getBase() - SystemClock.elapsedRealtime(); mChronometer.stop(); We will also use this variable to adjust the chronometer before starting it: mChronometer.setBase(SystemClock.elapsedRealtime() +
