Countdown Timer sometime, counts 2 seconds before the actual time

I have tried to make an countdown timer in a list veiw implementation. Each list item has a separate countdown timer that can be started or stopped. However I have noticed that if I add the first timer in list and set its time. When I start the timer it starts two seconds less than the actual time. e.g If I added a count down of 12 seconds. Then it will start counting from 10. But when the countdown is taking place and I add another new timer and set its time, it starts on the exact given time. The new counter starts at the wrong time only when either there is no other counter in the list or when all counters are already stopped and not counting down. Similarly it will only start the right time only when other timers are counting down. Would really appreciate if someone can help me figure out where is the problem. I have been looking at the code for days.
Here's my Adapter class

}
}
}
};
public CustomAdapterCounter(Context context, List<CounterData> l) {
super(context, 0, l);
this.context = context;
lstHolders = new ArrayList<>();
list = l;
mInflater = LayoutInflater.from(context);
for(int i=0; i<list.size(); i++) {
CounterData[] array = list.toArray(new CounterData[list.size()]);
if(!array[i].isStopped)

}

}
public void setCounterID(int id) {

}
public int getCounterID() {

}
}
And I add the time from number pickers of Hour, Minute and Second.
case R.id.counterStartStopButton:
long hour = TimeUnit.HOURS.toMillis(numberPickerHour.getValue());
long minute = TimeUnit.MINUTES.toMillis(numberPickerMinute.getValue());
long second = TimeUnit.SECONDS.toMillis(numberPickerSecond.getValue());
// if(getListSharedPreferences()) {

list.add(new CounterData(hour + minute + second, counterID));
saveCounterIDSharedPreferences(counterID);
}
else {
counterID = 1;
list.add(new CounterData(hour + minute + second, counterID));
saveCounterIDSharedPreferences(counterID);
}
UPDATE
Here's the shared preferences code
public void saveCounterIDSharedPreferences(int id) {
SharedPreferences sharedPreferences = this.getSharedPreferences("com.example.app", Context.MODE_PRIVATE);
sharedPreferences.edit().putInt("Counter ID123", id).commit();
}
public boolean getCounterIDSharedPreferences() {
SharedPreferences sharedPreferences = this.getSharedPreferences("com.example.app", Context.MODE_PRIVATE);
if (sharedPreferences.getInt("Counter ID123", -1) != -1) {
counterID = sharedPreferences.getInt("Counter ID123", -1);
return true;
}
else
return false;
}

What turned out to work for me was changing the timer task as following:
private void startUpdateTimer() {
Timer tmr = new Timer();
tmr.schedule(new TimerTask() {
#Override
public void run() {
mHandler.post(updateRemainingTimeRunnable);
}
}, 500, 500);
}

Android Chronometer - Save time

I´m using a Chronometer in my Android App. I can start it, stop it and continue counting after pushing the start button again:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_projektbeschreibung, container, false);
if (savedInstanceState != null){
stoppedmillis = savedInstanceState.getLong(STATE_TIME);
hh = savedInstanceState.getString(STATE_HH);
mm = savedInstanceState.getString(STATE_MM);
ss = savedInstanceState.getString(STATE_SS);
}
mChronometer = (Chronometer) rootView.findViewById(R.id.chronometer2);
mChronometer.setText(hh + ":" + mm + ":" + ss);
mChronometer.setOnChronometerTickListener(new Chronometer.OnChronometerTickListener() {
#Override
public void onChronometerTick(Chronometer cArg) {
long time = SystemClock.elapsedRealtime() - cArg.getBase() ;
int h = (int) (time / 3600000);
int m = (int) (time - h * 3600000) / 60000;
int s = (int) (time - h * 3600000 - m * 60000) / 1000;
hh = h < 10 ? "0" + h : h + "";
mm = m < 10 ? "0" + m : m + "";
ss = s < 10 ? "0" + s : s + "";
cArg.setText(hh + ":" + mm + ":" + ss);
}
});
((Button) rootView.findViewById(R.id.startbutton)).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//if first start
if(stoppedmillis == 0) {
mChronometer.setBase(SystemClock.elapsedRealtime());
} else {//Point A
long pausetime = (SystemClock.elapsedRealtime() - stoppedmillis);
mChronometer.setBase(mChronometer.getBase() + pausetime);
}
mChronometer.start();
}
});
((Button) rootView.findViewById(R.id.stopbutton)).setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view) {
mChronometer.stop();
stoppedmillis = SystemClock.elapsedRealtime();
}
});
After a screen rotation (so the Activity restarts) the chronometer starts counting from the point of 00:00:00 again. My first try was to save the stoppedmillis with a onSaveInstanceState method like the following:
public void onSaveInstanceState(Bundle savedInstanceState){
savedInstanceState.putLong(STATE_TIME, stoppedmillis);
savedInstanceState.putString(STATE_HH, hh);
savedInstanceState.putString(STATE_MM, mm);
savedInstanceState.putString(STATE_SS,ss);
super.onSaveInstanceState(savedInstanceState);
}
Now, I can get the value of the stoppedmillis after a restart, but I don't know how to set the Base for the Chronometer with the help of the stoppedmillis. At Point A in the Code you can see how it works with stopping the Chronometer with a button but this part of code does not working after a screen rotation.

I know that this is old. Although, I have created a simple application using a chronometer and done the following and it has kept counting across screen rotation. It is spot on with Andrew's original answer. Here is how I outlined it:
Chronometer mChronometer; // this is a global variable
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mChronometer = (Chronometer)findViewById(R.id.chronometer);
if(savedInstanceState != null){
mChronometer.setBase(savedInstanceState.getLong("ChronoTime"));
mChronometer.start();
}
}
Now set up onSaveInstanceState:
#Override
public void onSaveInstanceState (Bundle savedInstanceState){
super.onSaveInstanceState(savedInstanceState);
savedInstanceState.putLong("ChronoTime", mChronometer.getBase());
}

Fast solution, using this class:
https://github.com/ahmedrizwan/ChronometerPersist/blob/master/chronometerpersist/src/main/java/library/minimize/com/chronometerpersist/ChronometerPersist.java
ChronometerPersist chronometerPersist = ChronometerPersist.getInstance(chronometer, sharedPreferences);
//Starting the chronometer
startChronometer();
//Stoping the chronometer
stopChronometer();
//Pausing the chronometer
pauseChronometer();
I have lost much time trying to restore the current time with the android chronometer widget.

This is how i solved saving the state of the Chronometer.
private static final int TIME_MULTIPLIER = 60;
Step 1: Convert time to Seconds:
NOTE: If you don't like my method of converting time to second you could do your ways.
private static int convertTimeToSeconds(Long... time) {
int seconds = 0;
if (time.length == 2) {
seconds += time[0] * TIME_MULTIPLIER + time[1];
} else if (time.length == 3) {
seconds += (time[0] * TIME_MULTIPLIER) + (time[1] * TIME_MULTIPLIER) + (time[2]);
}
return seconds;
}
Step 2: Setting and starting time of Chronometer
NOTE: I'm saving the data in a custom object persist that object with any database / SharedPreference / your wish.
public static void setAndStartTime(final Chronometer chronometer) {
long second = 0;
// i have multiple time saved into map. You could save just 1 time and reuse that time.
for (DailyData data : DailyData.DailyDataHolder.getDailyDataMap().values()) {
second += data.getDailyTimeSpent();
}
chronometer.setBase(SystemClock.elapsedRealtime() - (second * 1000));
chronometer.start();
}
Step 3: Saving Time:
public static void saveTime(String timeText) {
String[] timeParts = timeText.split("[:]");
long savedTime = 0;
if (timeParts.length == 2) {
savedTime = convertTimeToSeconds(Long.parseLong(timeParts[0]), Long.parseLong(timeParts[1]));
} else if (timeParts.length == 3) {
savedTime = convertTimeToSeconds(Long.parseLong(timeParts[0]), Long.parseLong(timeParts[1]), Long.parseLong(timeParts[2]));
}
DailyData.DailyDataHolder.getDailyData().setDailyTimeSpent(savedTime);
}
Calling the saved method:
ChronoHelper.saveTime(chronometer.getText().toString());
COMPLETE CLASS:
public class ChronoHelper {
private static final int TIME_MULTIPLIER = 60;
public static void setAndStartTime(final Chronometer chronometer) {
long second = 0;
for (DailyData data : DailyData.DailyDataHolder.getDailyDataMap().values()) {
second += data.getDailyTimeSpent();
}
chronometer.setBase(SystemClock.elapsedRealtime() - (second * 1000));
chronometer.start();
}
public static void saveTime(String timeText) {
String[] timeParts = timeText.split("[:]");
long savedTime = 0;
if (timeParts.length == 2) {
savedTime = convertTimeToSeconds(Long.parseLong(timeParts[0]), Long.parseLong(timeParts[1]));
} else if (timeParts.length == 3) {
savedTime = convertTimeToSeconds(Long.parseLong(timeParts[0]), Long.parseLong(timeParts[1]), Long.parseLong(timeParts[2]));
}
DailyData.DailyDataHolder.getDailyData().setDailyTimeSpent(savedTime);
}
private static int convertTimeToSeconds(Long... time) {
int seconds = 0;
if (time.length == 2) {
seconds += time[0] * TIME_MULTIPLIER + time[1];
} else if (time.length == 3) {
seconds += (time[0] * TIME_MULTIPLIER) + (time[1] * TIME_MULTIPLIER) + (time[2]);
}
return seconds;
}
public static String secondsToTimeText(DailyData dailyData) {
long savedSeconds = dailyData.getDailyTimeSpent();
long minutes = savedSeconds / TIME_MULTIPLIER;
long seconds = savedSeconds % TIME_MULTIPLIER;
long hours = minutes / TIME_MULTIPLIER;
return hours + ":" + minutes + ":" + seconds;
}
}

Save the base time of the chronometer in onSaveInstanceState and set it back in onRestoreInstanceState like this:
public void onSaveInstanceState(Bundle savedInstanceState) {
savedInstanceState.putLong("ChronoTime", mChronometer.getBase());
super.onSaveInstanceState(savedInstanceState);
}
public void onRestoreInstanceState(Bundle savedInstanceState){
if((savedInstanceState !=null) && savedInstanceState.containsKey("ChronoTime"))
mChronometer.setBase(savedInstanceState.getLong("ChronoTime"));
super.onRestoreInstanceState(savedInstanceState);
}

CountDownTimer not working properly

for (int i=0; i<HisXArray.size(); i++) {
ycoord2 = HisYArray.get(i);
major2 = HisMajorArray.get(i);
xcoord2 = HisXArray.get(i);
minor2 = HisMinorArray.get(i);
time3 = TimeArray.get(i);
timer = new CountDownTimer(time3, 1000) {
#Override
public void onFinish() {
Log.e("Timer", xcoord2 + " " + ycoord2 + " " + time3);
mView.mFadePaint.setColor(Color.BLACK);
mView.drawOval(mView.mCanvas, xcoord2, ycoord2, 2*major2, 2*minor2, mView.mFadePaint);
mView.invalidate();
}
#Override
public void onTick(long millisUntilFinished) {
// TODO Auto-generated method stub
}
}.start();
When I'm trying to draw something using timer, onFinish called only when time3 = 0 and when i = HisXArray.size() - 1, i.e. the last.

Implement any intermediate steps in onTick(). By design, onFinish() is only called when the countdown is complete.

Settext Method of Textview

I am working on implementing a stopwatch by using a Chronometer and a Textview. The problem i am facing is that the Settext method refreshes the UI which disturbs the offsettopandbottom method i am using for animation on my ListView.
Is there any way that the Settext method only refreshes the Textview or does not disturb my Listview.
Code for the chronometer
stopwatch.setOnChronometerTickListener(new OnChronometerTickListener() {
#Override
public void onChronometerTick(Chronometer arg0) {
int countup = (int) ((SystemClock.elapsedRealtime() - arg0
.getBase()) / 1000);
String asText = (countup / 60) + ":" + (countup % 60);
tvtimer.setText("Time Elapsed :- " + asText);
}

Create a handler and use that as to set your TextView's text.
Handler handler = new Handler(){
#Override
public void handleMessage(Message msg) {
// TODO Auto-generated method stub
String message = (String) msg.obj.toString();
// Set your UI mods here
tvtimer.setText("Time Elapsed :- " + message);
super.handleMessage(msg);
}
};
// Then in your TickListener, do this:
stopwatch.setOnChronometerTickListener(new OnChronometerTickListener() {
#Override
public void onChronometerTick(Chronometer arg0) {
int countup = (int) ((SystemClock.elapsedRealtime() - arg0
.getBase()) / 1000);
String asText = (countup / 60) + ":" + (countup % 60);
// Send a message to your handler
Message msg = new Message();
msg.obj = asText;
handler.sendMessage(msg);
}
Hope it helps :)

Android saved activity state in onResume?
