I don't know why the last tick is not working but you can create your own timer with Runable , for example.
class MyCountDownTimer {
private long millisInFuture;
private long countDownInterval;
public MyCountDownTimer(long pMillisInFuture, long pCountDownInterval) {
this.millisInFuture = pMillisInFuture;
this.countDownInterval = pCountDownInterval;
}
public void Start()
{
final Handler handler = new Handler();
Log.v("status", "starting");
final Runnable counter = new Runnable(){
public void run(){
if(millisInFuture <= 0) {
Log.v("status", "done");
} else {
long sec = millisInFuture/1000;
Log.v("status", Long.toString(sec) + " seconds remain");
millisInFuture -= countDownInterval;
handler.postDelayed(this, countDownInterval);
}
}
};
handler.postDelayed(counter, countDownInterval);
}
}
and to start it,
new MyCountDownTimer(10000, 2000).Start();
EDIT FOR GOOFY'S QUESTION
you should have a variable to hold counter status (boolean) . then you can write a Stop() method like Start().
EDIT-2 FOR GOOFY'S QUESTION
actually there is no bug on stopping counter but there is a bug on start again after stop(resume).
I'm writing a new updated full code that I had just tried and it's working. It's a basic counter that show time on screen with start and stop button.
class for counter
public class MyCountDownTimer {
private long millisInFuture;
private long countDownInterval;
private boolean status;
public MyCountDownTimer(long pMillisInFuture, long pCountDownInterval) {
this.millisInFuture = pMillisInFuture;
this.countDownInterval = pCountDownInterval;
status = false;
Initialize();
}
public void Stop() {
status = false;
}
public long getCurrentTime() {
return millisInFuture;
}
public void Start() {
status = true;
}
public void Initialize()
{
final Handler handler = new Handler();
Log.v("status", "starting");
final Runnable counter = new Runnable(){
public void run(){
long sec = millisInFuture/1000;
if(status) {
if(millisInFuture <= 0) {
Log.v("status", "done");
} else {
Log.v("status", Long.toString(sec) + " seconds remain");
millisInFuture -= countDownInterval;
handler.postDelayed(this, countDownInterval);
}
} else {
Log.v("status", Long.toString(sec) + " seconds remain and timer has stopped!");
handler.postDelayed(this, countDownInterval);
}
}
};
handler.postDelayed(counter, countDownInterval);
}
}
