I have developed a Count Down Timer and I am not sure how to pause and resume the timer as the textview for the timer is being clicked. Click to start then click again to pause and to resume, click again the timer's text view.
This is my code:
Timer = (TextView) this.findViewById(R.id.time); //TIMER
Timer.setOnClickListener(TimerClickListener);
counter = new MyCount(600000, 1000);
}//end of create
private OnClickListener TimerClickListener = new OnClickListener() {
public void onClick(View v) {
updateTimeTask();
}
private void updateTimeTask() {
if (decision == 0) {
counter.start();
decision = 1;
} else if (decision == 2) {
counter.onResume1();
decision = 1;
} else {
counter.onPause1();
decision = 2;
}//end if
}
;
};
class MyCount extends CountDownTimer {
public MyCount(long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
}//MyCount
public void onResume1() {
onResume();
}
public void onPause1() {
onPause();
}
public void onFinish() {
Timer.setText("00:00");
p1++;
if (p1 <= 4) {
TextView PScore = (TextView) findViewById(R.id.pscore);
PScore.setText(p1 + "");
}//end if
}//finish
public void onTick(long millisUntilFinished) {
Integer milisec = new Integer(new Double(millisUntilFinished).intValue());
Integer cd_secs = milisec / 1000;
Integer minutes = (cd_secs % 3600) / 60;
Integer seconds = (cd_secs % 3600) % 60;
Timer.setText(String.format("%02d", minutes) + ":"
+ String.format("%02d", seconds));
///long timeLeft = millisUntilFinished / 1000;
/}//on tick
}//class MyCount
protected void onResume() {
super.onResume();
//handler.removeCallbacks(updateTimeTask);
//handler.postDelayed(updateTimeTask, 1000);
}//onResume
@Override
protected void onPause() {
super.onPause();
//do stuff
}//onPause
I have a simple solution. All you have to do is add an extra variable which stores the current time. The only addition is currentMillis at top and in onTick(). Use cancel() to pause.
PS: I'm using butterknife library, it's used to avoid using findviewbyid and setonclicklisteners. If you do not want to use it then you can just use the basic way of setting listeners and findviewbyid.
}
You can try using a library I created, Hourglass
Use
hourglass.startTimer();
to start the timer.It has helper methods which allow to pause and resume the timer.
AND
A nice and simple way to create a Pause/Resume for your CountDownTimer is to create a separate method for your timer start, pause and resume as follows:
The timerStart has a long parameter as it will be reused by the resume() method below. Remember to store your milliTillFinished (above as milliLeft) so that you may send it through in your resume() method. Pause and resume methods below respectively:
Here is the code for the button FYI:
Well there are no API to pause or resume it. What you should do is
cancel()
the timer and store the time remaining in a variable. When the resume button is hit again, restart the timer with the value from the variable.You know Chronometers may be of interest to you.
