I have to restart a CountDownTimer. I read a lot of question here but no one of the answer helped me.
When I use the following code
if(Const.counter != null){
Const.counter.cancel();
Const.counter = null;
}
Const.counter = new CustomTimerTask(Const.currentLevel.timeGoal * 1000,1000);
Const.counter.start();
I started a new counter but the old one also continues work. Please help me solve it.
You can realize it by cancelling and restarting. The following example should work.
CountDownTimer mCountDownTimer = new CountDownTimer(500, 1000) {
#Override
public void onTick(long millisUntilFinished) {}
#Override
public void onFinish() {
isCounterRunning = false;
}
};
boolean isCounterRunning = false;
private void yourOperation() {
if( !isCounterRunning ){
isCounterRunning = true;
mCountDownTimer.start();
}
else{
mCountDownTimer.cancel(); // cancel
mCountDownTimer.start(); // then restart
}
}
I did some different trick here. Hope this will help you.
if (myCountDownTimer != null) {
myCountDownTimer.cancel();
}
myCountDownTimer = new MyCountDownTimer(10000, 500);
myCountDownTimer.start();
coutdown timer for quiz
if(countDownTimer!=null)
{
countDownTimer.cancel();
countDownTimer.start();
}
else {
countDownTimer = new CountDownTimer(30000, 1000) {
public void onTick(long l) {
mtimer.setText("remaining time" + l / 1000);//mtime is a textview
}
public void onFinish() {//here mnext is the button from which we can get next question.
mnext.performClick();//this is used to perform clik automatically
}
}.start();
Just call again the start() method:
CountDownTimer cdt = new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
}
public void onFinish() {
this.start(); //start again the CountDownTimer
}
};
private fun startTimer() {
var timeInMilliSeconds = 11000L
val countDownTimer: CountDownTimer = object : CountDownTimer(timeInMilliSeconds, 1000) {
override fun onFinish() {
Timber.d("Times Up!")
setupResult("")
this.cancel()
timeInMilliSeconds = 11000L
this.start()
}
override fun onTick(p0: Long) {
val seconds = (p0 / 1000) % 60
Timber.d("Timer: $p0")
timer?.text = "$seconds"
}
}
countDownTimer.start()
}

where should I edit this code, that i can stop the CountDown ?
How to delete the old one before I start the next new CountDown ?
public void MyCounter1(){
new CountDownTimer(60000, 1000) {
public void onTick(long millisUntilFinished) {
txt_timer.setText("Left time : " + millisUntilFinished / 1000);
}
public void onFinish() {
txt_timer.setText("done");
}
}.start();
}
here is code:
CountDownTimer timer= null;
public void MyCounter1(){
timer =new CountDownTimer(60000, 1000) {
public void onTick(long millisUntilFinished) {
txt_timer.setText("Left time : " + millisUntilFinished / 1000);
}
public void onFinish() {
txt_timer.setText("done");
}
};
timer.start();
}
// To stop & start new timer check not null of timer instance first then cancel existing timer & start new one
if(timer != null){
timer.cancel();
MyCounter1();
}
also if you want to cancel first instance and start new one you can add above lines in onFinish method which will be get called when timer finish his time.
check this:
CountDownTimer timer= null;
public void MyCounter1(){
timer =new CountDownTimer(60000, 1000) {
public void onTick(long millisUntilFinished) {
txt_timer.setText("Left time : " + millisUntilFinished / 1000);
}
public void onFinish() {
txt_timer.setText("done");
if(timer != null){
timer.cancel();
MyCounter1();
}
}
};
timer.start();
}
I did these 2 lines. I works at the time fine:
public void MyCounter1(){
CountDownTimer countDownTimer = new CountDownTimer(60000, 1000) {
public void onTick(long millisUntilFinished) {
if(my_condition=1){ //1- just make my_condition<>1 to stop the counter
txt_timer.setText("Left time : " + millisUntilFinished / 1000); }
}
public void onFinish() {
countDownTimer.cacel(); // 2- delete old one
txt_timer.setText("done");
}
}.start();
}
private int time = 10; //example 10 min.
CountDownTimer(60000 * time, 1000)
#Override
public void onFinish() {
txt_timer.setText("done");
cancel();
time = 0;
I try to do app which show elements. Each element should start showing when the before element was hidden. Each element is showing 2 seconds.
Code:
public void gameStart()
{
do
{
data = random.nextInt(6) + 1;
if (data == 1)
{
CountDownTimer cdt = new CountDownTimer(2000, 1000)
{
#Override
public void onTick(long millisUntilFinished)
{
element1.setVisibility(View.VISIBLE);
}
#Override
public void onFinish()
{
element1.setVisibility(View.GONE);
}
}.start();
{
CountDownTimer cdt = new CountDownTimer(2000, 1000)
{
#Override
public void onTick(long millisUntilFinished)
{
element2.setVisibility(View.VISIBLE);
}
#Override
public void onFinish()
{
element2.setVisibility(View.GONE);
}
}.start();
} else if (data == 3)
{
CountDownTimer cdt = new CountDownTimer(2000, 1000)
{
#Override
public void onTick(long millisUntilFinished)
{
element3.setVisibility(View.VISIBLE);
}
#Override
public void onFinish()
{
element3.setVisibility(View.GONE);
}
}.start();
} else if (data == 4)
{
CountDownTimer cdt = new CountDownTimer(2000, 1000)
{
#Override
public void onTick(long millisUntilFinished)
{
element4.setVisibility(View.VISIBLE);
}
#Override
public void onFinish()
{
element4.setVisibility(View.GONE);
}
}.start();
} else if (data == 5)
{
CountDownTimer cdt = new CountDownTimer(2000, 1000)
{
#Override
public void onTick(long millisUntilFinished)
{
element5.setVisibility(View.VISIBLE);
}
#Override
public void onFinish()
{
element5.setVisibility(View.GONE);
}
}.start();
} else if (data == 6)
{
CountDownTimer cdt = new CountDownTimer(2000, 1000)
{
#Override
public void onTick(long millisUntilFinished)
{
element6.setVisibility(View.VISIBLE);
}
#Override
public void onFinish()
{
element6.setVisibility(View.GONE);
}
}.start();
}
id = id + 1;
text.setText("cos " + id);
} while (id < 3);
All elements are being shown in the same time. And I try add
Thread.sleep(2500);
But this stoped the action in window. I try add this after code:
Timer timer = new Timer();
timer.schedule( new TimerTask() {
public void run() {
}
}, 0, 60*1000);
But loop wasn't stay. I try do it with notify() and wait(), but it also don't work.
Don't suggest me to do do next action in onFinish() because this must be repeat a lot.
Anybody have another idea?
EDIT
I also use Handler but it don't work
I would recommend you not to implement this code in the main thread.
Create an async task, which hides a button and on postExequte calls itself.
I was doing a basic test on "CountDownTimer" and after a particular sec i want to stop
the countdowntimer completely. i used the method cancel but its not working the way i want
please help me out.
below is the complete code
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
display = (TextView)findViewById(R.id.txtView);
startTimer();
}
public void startTimer()
{
countDownTimer = new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
secondsLeft = millisUntilFinished / 1000;
display.setText("seconds remaining: " + secondsLeft );
if(secondsLeft == 10)
{
display.setText("CountDownTimer Canceled");
countDownTimer.cancel();
}
}
public void onFinish() {
display.setText("done!");
}
}.start();
}
Try following code, worked for me
if(TimeUnit.MILLISECONDS.toMinutes( millisUntilFinished)==0<put min here> && TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) -
TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished))==50<put your seconds here>)
{
display.setText("CountDownTimer Canceled");
countDownTimer.cancel();
}
Hope this will help
Ive been looking to see a method to see if a CountDownTimer is running or not, but I cant find a way to, any help would be greatly appreciated
if (position == 0) {
mCountDown = new CountDownTimer((300 * 1000), 1000) {
public void onTick(long millisUntilFinished) {
mTextField.setText("seconds remaining: "
+ millisUntilFinished / 1000);
}
public void onFinish() {
mTextField.setText("0:00");
String path = "/sdcard/Music/ZenPing.mp3";
try {
mp.reset();
mp.setDataSource(path);
mp.prepare();
mp.start();
} catch (IOException e) {
Log.v(getString(R.string.app_name),
e.getMessage());
}
}
}.start();
}
For that how can I check if mCountDown is currently running?
Just put a boolean flag which indicate that by following code
boolean isRunning = false;
mCountDown = new CountDownTimer((300 * 1000), 1000) {
public void onTick(long millisUntilFinished) {
isRunning = true;
//rest of code
}
public void onFinish() {
isRunning= false;
//rest of code
}
}.start();
onTick is your callback for a running process, you can either set a property to track the status.
isTimerRunning =false;
After start -> make it true;
Inside OnTick -> make it true (not actually required, but a double check)
Inside OnFinish -> make it false;
use the isTimerRunning property to track the status.
Check if the CountDownTimer is Running and also if the app is running in the background.
#Override
protected void onCreate(Bundle savedInstanceState) {
...
myButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
myButton.setText("Button clicked");
countDownTimer = new CountDownTimer( 3000, 1000) {
#Override
public void onTick(long millisUntilFinished) {
//After turning the Smartphone the follow both methods do not work anymore
if (!runningBackground) {
myButton.setText("Calc: " + millisUntilFinished / 1000);
myTextView.setText("Calc: " + millisUntilFinished / 1000);
}
}
#Override
public void onFinish() {
if (!runningBackground) {
//Do something
}
mTextMessage.setText("DONE");
runningBackground = false;
running = false;
}
};
//timer started
countDownTimer.start();
running = true;
}
});
}
#Override
protected void onResume() {
super.onResume();
runningBackground = false;
}
#Override
protected void onPause() {
runningBackground = true;
super.onPause();
}
Basically my aim is to have this timer reset whenever the user presses button b. I've tried a few methods such as if( i==true && bIsPressed()) but no luck, any ideas?
//2 buttons
Button =b;
TextView = time;
//countdown code
CountDownTimer Count = new CountDownTimer(11000, 1000) {
public void onTick(long millisUntilFinished) {
time.setText(""+millisUntilFinished / 1000);
}
public void onFinish() {
time.setText("Finished");
}
}; Count.start();
Haven't tested it, but I would do something along the lines of:
private void setupTimerResetButton()
{
mTimerResetButton.setOnClickListener(new OnClickListener(){
public void onClick(){
resetTimer();
}
});
}
private void resetTimer()
{
if(mTimer != null){
mTimer.cancel();
mTimer = null;
}
mTimer = new CountDownTimer(11000, 1000) {
public void onTick(long millisUntilFinished) {
mTimerTextView.setText(""+millisUntilFinished / 1000);
}
public void onFinish() {
mTimerTextView.setText("Finished");
}
};
mTimer.start();
}
