what should i take timer or what?
elapsetime = (TextView)findViewById(R.id.txtElapsedTime);
elapsetime.setText(" "+hour+" h "+min+" m");
any suggestions?
Use CountDownTimer.
Use this : Example of showing a 30 second countdown
new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
}
public void onFinish() {
mTextField.setText("done!");
}
}.start();
stop the Counter we use the countDownTimer.cancel()
if you want to Pause and Resume the timer refer below link

I am trying to make a Global countdown timer.
Could you tell how to make it working?
I haven't tried this myself, but some quick searching found a CountDownTimer class in Android that looks like it might work for you.
The example code they give looks pretty straightforward:
new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
}
public void onFinish() {
mTextField.setText("done!");
}
}.start();
Ive been working hard this week at learning android, and one thing I cant find a good
example for is timers, so if someone could maybe take the time to write asimple timer that counts down and displays in a textview, i would be eternally grateful, thanks a lot!
Following code will start from 30sec and end when it reaches 1 sec. Please note that timer uses milliseconds instead for seconds.
1 sec = 1000 milliseconds
Thus, 30 sec = 30x1000 milliseconds
mTextField is your regular TextView, replace it with your own TextView.
new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
}
public void onFinish() {
mTextField.setText("done!");
}
}.start();
how to use chronometer end to starting time? ineed 00:59 to 00:00 how can i use the code?

If you are looking for a cowntdown, try implementig the CountDownTimer android class. Here's a quick example:
new CountDownTimer(30000, 1000) { //the timer runs for 30 seconds in this case
public void onTick(long millisUntilFinished) {
mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
}
public void onFinish() {
mTextField.setText("done!");
}
}.start();
Hope this helps!
Can anyone demonstrate how to display only the seconds part of the digital clock widget.
Schedule a countdown until a time in the future, with regular notifications on intervals along the way. Example of showing a 30 second countdown in a text field:
new CountdownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
}
public void onFinish() {
mTextField.setText("done!");
}
}.start();
