Android - CountDownTimer will not use a variable as the first parameter - android

I'm trying to pass the countdowntimer a variable and use that variable as the amount of milliseconds to count down. If I simply enter the value the countdown works properly, but if I pass it a long variable it just runs the onFinish function.
Here's the actual code:
public CountDownTimer countDown = new CountDownTimer(respawnTime, 1000) {
#Override
public void onTick(long millisUntilFinished) {
timer =(Integer)(int) millisUntilFinished / 1000;
if(timer < 31)
timerText.setTextColor(Color.parseColor("#FF0000"));
timerText.setText(timer.toString());
}
#Override
public void onFinish() {
timerText.setTextColor(Color.parseColor("#00FF00"));
timerText.setText("UP");
}
};
At this point I have respawnTime set to equal 360000 hoping for a 360 second countdown, but like I said it just immediately runs the onFinish. Simply changing the first parameter to a literal instead of a variable fixes everything but I need to use a variable here. Thanks in advance for the help!

Change
#Override
public void onTick(long millisUntilFinished) {
to
#Override
public void onTick(long respawnTime) {
use the variable you are sending in the constructor in onTick().
Edit
Here is one of mine
private class MyCountDown extends CountDownTimer
{
long duration, interval;
public MyCountDown(long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
// TODO Auto-generated constructor stub
duration = millisInFuture;
interval = countDownInterval;
start();
}
#Override
public void onFinish() {
secs = 10;
Intent intent = new Intent(CalibrationTimeoutScreen.this, CalibrationTakeTempScreen.class);
intent.addCategory(Intent.CATEGORY_DEFAULT);
startActivity(intent);
CalibrationTimeoutScreen.this.finish();
}
#Override
public void onTick(long duration) {
cd.setText(String.valueOf(secs));
secs = secs - 1;
}
}

You did not run start(). Simply add .start() after the last '}' or add a new line calling countDown.start().

Android: Get passed time of a normal CountDownTimer?

Is there a way to save the exact passed time (either milliseconds, seconds or minutes is fine) of a CountDownTimer?
new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
}
public void onFinish() {
mTextField.setText("done!");
}
}.start();
I tried increasing a variable in onTick(), but the problem is, my timer is cancel and restartable over a Button, and onTick() gets called everytime I start the timer, no matter if a second passed or not. So if I click the Button multiple times in 1 second, onClick() gets called every single click, rather than once per second.
You can use System.currentTimeMillis(), is this what you are after?
public class MyCountDownTimer extends CountDownTimer {
long timeStart;
public MyCountDownTimer(long x, long y) {
super(x, y);
timeStart = System.currentTimeMillis();
}
#Override
public void onTick(long millisUntilFinished) {
long timeLapsed = System.currentTimeMillis() - timeStart;
/// your code
}
#Override
public void onFinish() {
/// your code
}
}

Close and go to an activity after user downtime

I want to make a method (service, alarm, etc.) that can be calculated after x downtime user with the app
Which closes the current activity
and will send the initial activity (login)
Thank you very much
http://androidbite.blogspot.in/2012/11/android-count-down-timer-example.html
new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
//here you can have your logic to set text to edittext
}
public void onFinish() {
mTextField.setText("done!");
}
}.start();
Refer this link and some examples on countdown timer if you want to use this.
I answer
code is
private long startTime=15*60*1000; // 15 MINS IDLE TIME
private final long interval = 1 * 1000;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
countDownTimer = new MyCountDownTimer(startTime, interval);
}
#Override
public void onUserInteraction(){
super.onUserInteraction();
//Reset the timer on user interaction...
countDownTimer.cancel();
countDownTimer.start();
}
public class MyCountDownTimer extends CountDownTimer {
public MyCountDownTimer(long startTime, long interval) {
super(startTime, interval);
}
#Override
public void onFinish() {
//DO WHATEVER YOU WANT HERE
// CIERRA LA APP MATANDO EL PROCESO Y VUELVE A ABRIRLO.
android.os.Process.killProcess(android.os.Process.myPid());
}
#Override
public void onTick(long millisUntilFinished) {
}
}
use
act.finishAffinity();
act.startActivity(new Intent(act, actMain.class));

CountDownTimer not accurate

I have an Android service running in the background.
I want to be notified after a specific period of time (22 seconds), so I wrote:
private CountDownTimer mCountDownTimer = new CountDownTimer(22*1000,22*1000) {
public void onTick(long millisUntilFinished) {}
public void onFinish() {
doSomething();
}
};
I run this, and get the notification after 40 seconds, and even 50 seconds. Am I doing something wrong? How can this be done?
Actually you are putting interval time as wll 22000, what this you are doing wrong. Second parameter is the interval.So , Do this :
CountDownTimer alertTimer = new CountDownTimer(22*1000, 1000) {
#Override
public void onTick(long millisUntilFinished) {
// Do here what you want
}
#Override
public void onFinish() {
}
}.start();

CounDownTimer how to set it for counting 2 times?

I'm doing an app which will use CountDownTimer
I would like to use 1 countdowntimer for 2 count downs.
If the time finishes, then a new time starts immediately, and so on.
For now I have something like this:
cdt = new CounDownTimer(time,1000) {
public void onTick(…) {
//code
}
public void onFinish() {
//and here I'm thinking to add a new time, but it doesn't work
}
};
How to do that? Or maybe is there other easier option to solve that problem?
Thanks for help!
Somewhere in your class newMyCountdownTimer(time, interval).start();
private class MyCountdownTimer extends CountDownTimer
{
public MyCountdownTimer(long millisInFuture, long countDownInterval)
{
super(millisInFuture, countDownInterval);
}
#Override
public void onFinish()
{
if (somecondition is satisfied) // be carefull otherwise the countdown keeps running
{
// newTime and newInterval are variables in the outer class
new MyCountdownTimer(newTime, newInterval).start();
}
}
#Override
public void onTick(long millisUntilFinished)
{
// TODO Auto-generated method stub
}
}

TimerTask in Android? [duplicate]

I have got an application where I need to show counter from 3 to 1 then quickly switch to another activity. Will TimerTask will be suitable for doing this? Can anybody show me an example of exactly how to do it?
CountDownTimer Worked. Code for showing timer for 3 seconds is.
new CountDownTimer(4000, 1000) {
public void onTick(long millisUntilFinished) {
Animation myFadeOutAnimation = AnimationUtils.loadAnimation(countdown.this, R.anim.fadeout);
counter.startAnimation(myFadeOutAnimation);
counter.setText(Long.toString(millisUntilFinished / 1000));
}
public void onFinish() {
counter.setText("done!");
}
}.start();
I would better use a CountDownTimer.
If you want for example your counter to count 3 seconds:
//new Counter that counts 3000 ms with a tick each 1000 ms
CountDownTimer myCountDown = new CountDownTimer(3000, 1000) {
public void onTick(long millisUntilFinished) {
//update the UI with the new count
}
public void onFinish() {
//start the activity
}
};
//start the countDown
myCountDown.start();
Use CountDownTimer as shown below.
Step1: create CountDownTimer class
class MyCount extends CountDownTimer {
public MyCount(long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
}
public void onFinish() {
dialog.dismiss();
// Use Intent to Navigate from this activity to another
}
#Override
public void onTick(long millisUntilFinished) {
// TODO Auto-generated method stub
}
}
Step2: create an object for that class
MyCount counter = new MyCount(2000, 1000); // set your seconds
counter.start();
