countdowntimer

问题 I have a CountdownTimer that counts down from 60 seconds. This CountdownTimer works by setting a textView to the remaining milliseconds, but whenever i rotate my device, the CountdownTimer gets reset. I know this happens because the Activity gets restarted on rotation. So i tried saving the time remaining in a bundle and then restoring it, after the Activity was restarted. long transferValue; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);

问题 I have an app with multiple timers; when I start one, I can see it counting down in Logcat in Eclipse. When I hit the Back button, onStop() is called in the app but the timer continues to countdown in logcat (the onTick() is continuing to tick away). What I would like is when onResume() is called, I want to get that timer which is still counting down and continue it. Is this possible? Here are my buttons that start the countdown: //Button1 Timer final CountDown button1 = new CountDown(420000

问题 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

问题 What I want to do in my app: 1. When the user opens the app, he will be able to see an already running countdown timer. So in that case I want to show the countdown numbers in a textview that will always update each second. 2. The user will be able to stop it. 3. The user can leave the application, but the countdown should still go on and show updated time when he comes back to the application UI. So based on the above points, I understand I need to implement Service that does work in the

问题 I've been using an android countdown timer sample to create a countdown to a certain date. Time TimerSet = new Time(); TimerSet.set(20, 8, 2012); //day month year TimerSet.normalize(true); long millis = TimerSet.toMillis(true); Time TimeNow = new Time(); TimeNow.setToNow(); // set the date to Current Time TimeNow.normalize(true); long millis2 = TimeNow.toMillis(true); long millisset = millis - millis2; //subtract current from future to set the time remaining final int smillis = (int) (millis)

问题 have a question about CountDownTimer. I have to make an application that allows the user to increment the time time by +1, for every click of the button. Then after the button stops being clicked it waits for three seconds, then starts to countdown. I pasted my code below. My Issue is: I can't seem to get the Incrementing of the number working correctly, however it seems that after I stop Incrementing the number (onStop()) it directly goes to (onFinish()). Instead of going to the OnTick() and

问题 This question already has answers here : Closed 6 years ago . Possible Duplicate: Stop timer with conditional only works first time? I'm very confused as to how to make a timer using the swing and not util timer. I am making a game where users have to answer questions in a 30 second time limit. I have a PlayFrame, where the time is shown, and a method inside PlayFrame called startTimer which contains all the timer stuff. public static void startTimer() { int elapsedSeconds = 0; javax.swing

问题 I am new to Android Development and trying to make little Game. CountDownTimer.cancel() is not working for me. Any Idea? Thank Your for your Answer! CountDownTimer cdt = new CountDownTimer(120000, 1000) { public void onTick(long millisUntilFinished) { maxTime = (int) (millisUntilFinished / 1000); timer.setText(String.valueOf(maxTime)); } public void onFinish() { } }; if (startTimer == true) { cdt.start(); } else { cdt.cancel(); } 回答1: I have to do an assumption right here because the code

问题 When writing : CountDownTimer timer = new CountDownTimer(1000, 100) { @Override public void onTick(long l) { } @Override public void onFinish() { }; }.start(); are we actually starting a new thread that handles ticks? If not, what is really happening? 回答1: CountDownTimer 's implementation uses Handler and sendMessageDelayed() , so no background thread is needed. This does mean that the timer will not update if you are tying up the main application thread elsewhere in your code. 回答2:
