I am trying to run the downcounter in a loop that is after 5seconds the counter starts counting again from 5 to 0.
I have tried this code
countDownTimer.cancel();
countDownTimer.start();
bt this does not work. The value in textview does not reset. Posted below is the complete code.
Regards!
private void timee() {
for (int j = 5; j > 0; j--) {
countDownTimer = new MalibuCountDownTimer(5000, 1000);
if (j == 4)
countDownTimer.start();
else {
countDownTimer.cancel();
countDownTimer.start();
}
}
}
// CountDownTimer class
public class MalibuCountDownTimer extends CountDownTimer {
public MalibuCountDownTimer(long startTime, long interval) {
super(startTime, interval);
}
#Override
public void onFinish() {
Toast.makeText(getApplicationContext(), "Done", Toast.LENGTH_SHORT).show();
// takeImage();
}
#Override
public void onTick(long millisUntilFinished) {
tt.setText("Time remain:" + millisUntilFinished / 1000);
}
}
Replace your timee() method and CountDownTimer class with following code
private void timee(){
MalibuCountDownTimer countDownTimer=new MalibuCountDownTimer(5000, 1000);
countDownTimer.start();
}
public class MalibuCountDownTimer extends CountDownTimer {
public MalibuCountDownTimer(long startTime, long interval) {
super(startTime, interval);
}
#Override
public void onFinish() {
Toast.makeText(getApplicationContext(), "Done", Toast.LENGTH_SHORT).show();
j++;
if(j<=5)
start();
}
#Override
public void onTick(long millisUntilFinished) {
m_tv_emp.setText("Time remain:" + millisUntilFinished / 1000);
}
}
note: take j as class varieble

I make a timer with a count time of 5 seconds, then when I press the exit button the counter automatically stops?
Here is my timer code:
public void startTimer(final long finish, long tick) {
CountDownTimer t;
t = new CountDownTimer(finish, tick) {
public void onTick(long millisUntilFinished) {
long remainedSecs = millisUntilFinished / 1000;
textTimer.setText("" + (remainedSecs / 60) + ":" + (remainedSecs % 60));// manage it accordign to you
}
public void onFinish() {
textTimer.setText("00:00");
Toast.makeText(FloatingVideoWidgetShowService.this, "Waktu Habis", Toast.LENGTH_SHORT).show();
long seek = videoView.getCurrentPosition();
videoView.setKeepScreenOn(false);
stopSelf();
WritableMap args = new Arguments().createMap();
args.putInt("index", index);
args.putInt("seek", (int) seek);
args.putString("url", playingVideo.getString("url"));
args.putString("type", "close");
sendEvent(reactContext, "onClose", args);
onDestroy();
cancel();
}
}.start();
}
And this is my code when pressing the stop / exit button :
floatingWindow.findViewById(R.id.btn_deny).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
long seek = videoView.getCurrentPosition();
videoView.setKeepScreenOn(false);
stopSelf();
WritableMap args = new Arguments().createMap();
args.putInt("index", index);
args.putInt("seek", (int) seek);
args.putString("url", playingVideo.getString("url"));
args.putString("type", "close");
sendEvent(reactContext, "onClose", args);
onDestroy();
}
});
How so when btn_deny is clicked Cuntdowntimer stops and does not force close?
Thanks.
You can't use onDestroy() to close your activity or fragment. Instead, you need to call finish().
To close the CountDownTimer, you need to make it a class scope variable. Prepare the timer at your startTimer then stop the timer by calling t.cancel() like the following code:
public class YourActivity extends Activity {
// Declare the variable to be accessed later.
CountDownTimer t;
...
public void startTimer(final long finish, long tick) {
t = new CountDownTimer(finish, tick) {
...
}.start();
}
private void yourOtherMethod() {
floatingWindow.findViewById(R.id.btn_deny).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(t != null) t.cancel();
...
}
});
}
}
I'm a beginner in Android programming. I'm trying to display a timer for an upgrade in my game to show how long the upgrade will be activated for. In my collision flag I call Looper.prepare and start my thread class as the logcat suggested I do. How would I get this to run on one looper?
Here is the snippet that starts the thread.
BigGapUpgrade.java
public boolean playerCollectUpgrade(Player player){
if(Rect.intersects(rectangle, player.getRectangle())){
Looper.prepare();
bigGapUpgradeHandler.start();
}
return Rect.intersects(rectangle, player.getRectangle());
}
And here is my thread class
BigGapUpgradeHandler.java
public class BigGapUpgradeHandler extends Thread {
TimerTask scanTask;
Timer timer = new Timer();
#Override
public void run() {
Looper.prepare();
scanTask = new TimerTask() {
public void run() {
}
};
timer.schedule(scanTask, 0, 4000);
CountDownTimer countDownTimer = new CountDownTimer(4000, 100) {
#Override
public void onTick(long l) {
Log.i(TAG, "onTick: ");
}
#Override
public void onFinish() {
timer.cancel();
Log.i(TAG, "onFinish: ");
}
}.start();
Looper.loop();
}
}
After running it I get this error
W/System.err: java.lang.RuntimeException: Only one Looper may be created per thread
--Edit
Here is the solution I came up with.
-- Solution
new Handler(Looper.getMainLooper()).post(new Runnable() {
#Override
public void run() {
CountDownTimer countDownTimer = new CountDownTimer(5000,100) {
#Override
public void onTick(long millisUntilFinished) {
millis = millisUntilFinished/100;
}
#Override
public void onFinish() {
}
}.start();
}
});
OK, So what you can do is just use a TimerTask. That creates it's own background thread for you do stuff:
// This TimerTask Updates the UI so it needs a reference to the Activity.
static class PowerUpTimerTask extends TimerTask
{
WeakReference<AppCompatActivity> mActivity;
long mInterval;
long mPeriod;
public PowerUpTimerTask(AppCompatActivity activity, long period, long interval)
{
mActivity = new WeakReference<>(activity);
mInterval = interval;
mPeriod = period;
}
#Override
public void run()
{
AppCompatActivity activity = mActivity.get();
if (activity != null)
{
final TextView timerTextView = activity.findViewById(R.id.timerTextView);
mPeriod -= mInterval;
if (mPeriod > 0)
{
// Set time remaining
activity.runOnUiThread(new Runnable()
{
#Override
public void run()
{
timerTextView.setText(String.valueOf(mPeriod));
}
});
}
else
{
// Out of time...clear the Text and stop the timer task.
activity.runOnUiThread(new Runnable()
{
#Override
public void run()
{
timerTextView.setText("");
}
});
Log.d(TAG, "Timer done. Canceling.");
cancel();
}
}
else
{
// Cancel this timer task since we don't have a reference to
// the Activity any more.
Log.d(TAG, "Lost reference to Activity. Canceling.");
cancel();
}
}
}
Then you can start your Timer task like so:
...
// Will count down from 10 by 1s.
mPowerUpTimerTask = new PowerUpTimerTask(this, powerUpTime, 1);
// Schedule for every second.
Timer t = new Timer();
t.scheduleAtFixedRate(mPowerUpTimerTask, 1000, 1000);
...
Here is a link to this running sample:
https://github.com/didiergarcia/TimerTaskExample
I think you have to use LocalBroadcastManager for the timing to continuously in loop. Please check below code for for that :-
private void startTimer() {
countDownTimer = new CountDownTimer(Constant.getInstance().ANSWER_TIME_IN_SECOND * 1000, 1000) {
public void onTick(long millisUntilFinished) {
remaininTimeInMillies = millisUntilFinished;
tvTimer.setText(getTime(Integer.parseInt(String.valueOf(millisUntilFinished))));
}
public void onFinish() {
Intent intent = new Intent(Constant.getInstance().TIMER_RECEIVER);
LocalBroadcastManager.getInstance(PatientDetailActivity.this).sendBroadcast(intent);
}
};
countDownTimer.start();
}
private String getTime(int milliSec) {
int minut = 0, second = 0;
minut = milliSec / 60000;
second = (milliSec - (minut * 60000)) / 1000;
String strMinute = "", strSecond = "";
if (minut < 10) {
strMinute = "0" + String.valueOf(minut);
} else {
strMinute = String.valueOf(minut);
}
if (second < 10) {
strSecond = "0" + String.valueOf(second);
} else {
strSecond = String.valueOf(second);
}
return strMinute + ":" + strSecond;
}
#Override
protected void onResume() {
LocalBroadcastManager.getInstance(this).registerReceiver(timerBroadcast, new IntentFilter(Constant.getInstance().TIMER_RECEIVER));
super.onResume();
}
#Override
protected void onDestroy() {
LocalBroadcastManager.getInstance(this).unregisterReceiver(timerBroadcast);
super.onDestroy();
}
Thanks and Hope that will help you
So I want certain action to be performed X number of times, depends on how many times user wants it. User selection will be selected from a TextView string which is set up with this code:
homeScreenPlus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dodajInterval();
homeScreenMinus.setEnabled(counter > 0);
}
});
homeScreenMinus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
oduzmiInterval();
homeScreenMinus.setEnabled(counter > 0);
}
});
}
private void oduzmiInterval() {
counter--;
brojIntervala.setText(Integer.toString(counter));
}
private void dodajInterval() {
counter++;
brojIntervala.setText(Integer.toString(counter));
}
Those are basicly two buttons that increment or decrement value of TextView.
The action I want to perform X times is this:
public void homeScreenStart(View view) {
linearniLayoutSetup.setVisibility(View.GONE);
new CountDownTimer(seekBarTimerDelay.getProgress() * 1000 + 100, 1000) {
#Override
public void onTick(long millisUntilFinished) {
updateTimer((int) millisUntilFinished / 1000);
}
#Override
public void onFinish() {
textViewTimerVrijeme.setText("00:00");
countDownTimerTrci();
karticaTimera.setBackgroundColor(getResources().getColor(R.color.kartica_trci));
textViewTimerTrciHodajBlaBla.setText(getResources().getString(R.string.timer_trci));
}
}.start();
}
private void countDownTimerTrci() {
toolbar.setBackgroundColor(getResources().getColor(R.color.kartica_trci));
new CountDownTimer(seekBarIntervaliVisokogIntenziteta.getProgress() * 1000 + 100, 1000){
#Override
public void onTick(long millisUntilFinished) {
updateTimer((int) millisUntilFinished / 1000);
}
#Override
public void onFinish() {
textViewTimerVrijeme.setText("00:00");
karticaTimera.setBackgroundColor(getResources().getColor(R.color.kartica_hodaj));
imageViewTimerSlika.setImageResource(R.drawable.ic_timer_niski_intenzitet);
textViewTimerTrciHodajBlaBla.setText(getResources().getString(R.string.timer_hodaj));
countDownTimerHodaj();
}
}.start();
}
private void countDownTimerHodaj(){
toolbar.setBackgroundColor(getResources().getColor(R.color.kartica_hodaj));
new CountDownTimer(seekBarIntervaliNiskogIntenziteta.getProgress() * 1000 + 100, 1000){
#Override
public void onTick(long millisUntilFinished) {
updateTimer((int) millisUntilFinished / 1000);
}
#Override
public void onFinish() {
textViewTimerVrijeme.setText("00:00");
karticaTimera.setBackgroundColor(getResources().getColor(R.color.colorAccent));
textViewTimerTrciHodajBlaBla.setText("Done!");
}
}.start();
}
So it is combination of 3 seekbars, or timers, one running after another and then they should run as many times as user selects.
The problem is, I have no idea how to set this up, and I need that first block of code in timers to run just once, and those 2 methods below it to run X times.
How can I do it?
Unless I am missing something couldn't you just wrap your code in the action in a loop that references the current counter? You may need to block input so that the user can not modify the counter (unless you want them to) after execution has begun but that should be it.
public void homeScreenStart(View view) {
linearniLayoutSetup.setVisibility(View.GONE);
CountDownTimer firstCountDown = new CountDownTimer(seekBarTimerDelay.getProgress() * 1000 + 100, 1000) {
#Override
public void onTick(long millisUntilFinished) {
updateTimer((int) millisUntilFinished / 1000);
}
#Override
public void onFinish() {
textViewTimerVrijeme.setText("00:00");
countDownTimerTrci();
karticaTimera.setBackgroundColor(getResources().getColor(R.color.kartica_trci));
textViewTimerTrciHodajBlaBla.setText(getResources().getString(R.string.timer_trci));
}
}
CountDownTimer secondCountDown = new CountDownTimer(seekBarIntervaliVisokogIntenziteta.getProgress() * 1000 + 100, 1000){
#Override
public void onTick(long millisUntilFinished) {
updateTimer((int) millisUntilFinished / 1000);
}
#Override
public void onFinish() {
textViewTimerVrijeme.setText("00:00");
karticaTimera.setBackgroundColor(getResources().getColor(R.color.kartica_hodaj));
imageViewTimerSlika.setImageResource(R.drawable.ic_timer_niski_intenzitet);
textViewTimerTrciHodajBlaBla.setText(getResources().getString(R.string.timer_hodaj));
countDownTimerHodaj();
}
}
CountDownTimer thirdCountDown = new CountDownTimer(seekBarIntervaliVisokogIntenziteta.getProgress() * 1000 + 100, 1000){
#Override
public void onTick(long millisUntilFinished) {
updateTimer((int) millisUntilFinished / 1000);
}
#Override
public void onFinish() {
textViewTimerVrijeme.setText("00:00");
karticaTimera.setBackgroundColor(getResources().getColor(R.color.kartica_hodaj));
imageViewTimerSlika.setImageResource(R.drawable.ic_timer_niski_intenzitet);
textViewTimerTrciHodajBlaBla.setText(getResources().getString(R.string.timer_hodaj));
countDownTimerHodaj();
}
}
for (int i = 0; i < counter; i++) {
firstCountDown.start();
toolbar.setBackgroundColor(getResources().getColor(R.color.kartica_trci));
secondCountDown.start();
thirdCountDown.start();
}
}
Should work for you
I have a countdown timer, I have a button that pause it, but I need that when you click on button, continue to countdown. I search but couldn't a function related this. How can do it? This is my code, I only managed to restart it, but not continue:
private TextView cuentaRegresiva;
private Button btnEmpezar;
private CountDownTimer countDownTimer;
private boolean timerHasStarted = false;
private long startTime = 30 * 1000;
private final long interval = 1 * 1000;
private long restante;
#Override
protected void onCreate(Bundle savedInstanceState) {
...
btnEmpezar.setOnClickListener(iniciar);
}
OnClickListener iniciar=new OnClickListener() {
#Override
public void onClick(View arg0) {
if (!timerHasStarted && !pausado) {
countDownTimer.start();
timerHasStarted = true;
btnEmpezar.setText("Pause");
pausado=false;
}
else if(timerHasStarted && !pausado){
countDownTimer.cancel();
timerHasStarted = false;
btnEmpezar.setText("Restart");
pausado=true;
}
else if(!timerHasStarted && pausado){
countDownTimer2.start();
timerHasStarted = true;
btnEmpezar.setText("Pause");
pausado=false;
}
}
};
public class MyCountDownTimer extends CountDownTimer {
public MyCountDownTimer(long startTime, long interval) {
super(startTime, interval);
}
#Override
public void onFinish() {
cuentaRegresiva.setText("Tiempo!");
}
#Override
public void onTick(long millisUntilFinished) {
cuentaRegresiva.setText("" + millisUntilFinished / 1000);
}
}
public class MyCountDownTimer2 extends CountDownTimer {
public MyCountDownTimer2(long restante, long interval) {
super(restante, interval);
}
#Override
public void onFinish() {
cuentaRegresiva.setText("Tiempo!");
}
#Override
public void onTick(long millisUntilFinished) {
cuentaRegresiva.setText("" + millisUntilFinished / 1000);
}
}
I thought about taking millisUntilFinished to a variable, but didn't work. Anyway I guess the way is close to that.
You can try saving the seconds until finish, and then you can start the new countdown timer with that seconds.
// -----------------------
Cuando presionas el boton de pausa, guarda los segundos que le faltan al timer para que termine. Entonces, cuando volves a apretar play, creas un nuevo CountDownTimer con esos segundos que te faltaban.
UPDATE
I did an example:
public class MainActivity extends Activity {
private static final int TIMER_TIME = 10000; // in millis
private Button btnCountdown;
private TextView tvTimeUntilFinish;
private boolean mIsPaused = true;
private long mMillisUntilFinish;
private CountDownTimer mTimer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mMillisUntilFinish = TIMER_TIME;
btnCountdown = (Button) findViewById(R.id.btnCountdown);
tvTimeUntilFinish = (TextView) findViewById(R.id.tvTimeUntilFinish);
btnCountdown.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
if (mIsPaused) {
btnCountdown.setText("Pause");
initTimer();
} else {
btnCountdown.setText("Play");
cancelTimer();
}
mIsPaused = !mIsPaused;
}
});
}
private void cancelTimer() {
if (mTimer != null) {
mTimer.cancel();
mTimer = null;
}
}
private void initTimer() {
mTimer = new CountDownTimer(mMillisUntilFinish, 1000) {
public void onTick(long millisUntilFinished) {
tvTimeUntilFinish.setText("seconds remaining: " + millisUntilFinished / 1000);
mMillisUntilFinish = millisUntilFinished;
}
public void onFinish() {
}
}.start();
}
}
This question already has an answer here:
Restart Countdown Timer with new time android
(1 answer)
Closed 8 years ago.
how to restart a timer in every button click? here given a sample code for timer setting
new CountDownTimer(3000, 1000) {
public void onTick(long millisUntilFinished) {
//getSelectedAlphabet.setText(selectedIndex.getText());
}
public void onFinish() {
//mTextField.setText("done!");
getSelectedAlphabet.setVisibility(View.INVISIBLE);
Log.d("Counter", "Finished....");
}
}.start();
Try this
CountDownTimer cdt;
cdt = new CountDownTimer(3000, 1000) {
public void onTick(long millisUntilFinished) {
//getSelectedAlphabet.setText(selectedIndex.getText());
}
public void onFinish() {
//mTextField.setText("done!");
getSelectedAlphabet.setVisibility(View.INVISIBLE);
Log.d("Counter", "Finished....");
}
}.start();
// to restart
cdt.cancel(); // to cancel
cdt.start(); //to start
final CountDownTimer remainingTimeCounter = new CountDownTimer(3000, 1000) {
public void onTick(long millisUntilFinished) {
}
public void onFinish() {
Log.d("Counter", "Finished....");
}
}.start();
findViewById(R.id.button1).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
remainingTimeCounter.cancel();
remainingTimeCounter.start();
}
});
final CounterClass timer = new CounterClass(180000,1000);
button.setOnclickListener(new OnClickListener() {
#Override
public void onClick(View view) {
timer.start();
}
};
CounterClass-
public class CounterClass extends CountDownTimer {
public CounterClass(long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
}
#Override
public void onFinish() {
System.out.println("finished");
}
#Override
public void onTick(long millisUntilFinished) {
long millis = millisUntilFinished;
String hms = String.format(
"%02d:%02d:%02d",
TimeUnit.MILLISECONDS.toHours(millis),
TimeUnit.MILLISECONDS.toMinutes(millis)
- TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS
.toHours(millis)),
TimeUnit.MILLISECONDS.toSeconds(millis)
- TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS
.toMinutes(millis)));
System.out.println(hms);
}
}
