timer

问题 I am using a timer that is canceled and restarted on a listener event. It all works fine except that the the timer thread leaks the whole outer class. My timer implementation is as follows: if(timer != null) { timer.cancel(); timer = null; timer = new Timer(); } timer.schedule(new TimerTask() { // Thread leaks!!!! @Override public void run() { mCallback.onHeaderMoving(newToolbarTranslationY ); } } , 150); I used MAT Analyser to track down the problem and ended up there. I also commented out

问题 I need for my personal project counting pulse and direction with timer. With this code I can count only one direction. Any suggestion are welcome for correct code (this code is pretesting) pulse count to PA_9 and direction input to PA_8 #include "mbed.h" #include "stm32f4xx.h" #include "stm32f4xx_hal_tim_ex.h" TIM_HandleTypeDef timer; TIM_Base_InitTypeDef inizializza; TIM_IC_InitTypeDef startclock; TIM_ClockConfigTypeDef ClockConfig; TIM_SlaveConfigTypeDef sSlaveConfigure; TIM

问题 When I try to use the Windows SetTimer function, it generate a IDEvent for the timer even if I have specified one! This: SetTimer(0,999,10000,@timerproc); In: procedure timerproc(hwnd: HWND; uMsg: UINT; idEvent: UINT_PTR;dwTime: DWORD); stdcall; begin KillTimer(0, idEvent); showmessage(inttostr(idevent)); end; Return: Random Number! Is it possible to manage my timers by myself instead of Windows choosing for me? Thank you very much! 回答1: If you want to handle multiple timer events in a single

问题 Okay, so basically what I'm trying to create a timer that counts up and down. I need the program to activate just one timer at any one time. There are two timers, one causing a variable to increment, the other to decrement. I can't seem to get it right, when I press the increment, the variable increments but never stops, even when I press the decrement button. How do I go about doing this? Also, another quick question : How do I return a value which is within a keypress method? Keypress are

问题 I want to stop a timer but in the middle of the tick, before the tick finishes. But when I use a button to stop the timer, it only stops it after the tick finishes all his functions. I'm using 4 radiobuttons and a timer that keeps changing the selected radiobutton. When I press the Stop button, my timer stops and I need to know what radiobutton is selected, but the timer just stops after the tick finishes, so the selected radiobutton changes. The code is: namespace teste_bola { public partial

问题 I have a System.Timer setup to trigger an event every day at 2AM. If the process the timer starts fails then I want the timer to be reset to run every 15 minutes until the process completes succesfully. // this is how the timer is set up. // this is working correctly. double startTime = milliseconds_of_hour_to_start. Timer = new System.Timers.Timer( startTime); Here is the code to reset the timer on success or failure of the event handler. NOTE the timer is not being stopped, just the

问题 I am testing the Angular Timer and have found myself wondering about how to get the current time inside my controller in order to use it to whatever purpose I might have. For instance, I want to set the font color of the timer to red when it reaches a specifict amount of minutes , but I was completely unable to do this. I tried the following: $scope.startTimer = function (deadline) { $scope.$broadcast('timer-start'); $scope.timerRunning = true; if ($scope.minutes == deadline) $scope.turnRed()

问题 I'd like to, essentially, have a high-priority thread, that runs at a given interval (here 0.5 ms) and interrupts "everything", executes a short task, and then goes back to 'sleep'; using Ubuntu 11.04 and perl v5.10.1. The problem is, while I'm getting some sort of results, I am not sure whether it's possible to get "tight timing". I have made three test scripts, in which the 'loop' is basically increasing a counter 10 times, taking timestamps - and then it terminates, and the timestamps are

问题 C++, XCode 4.6.3, OSX 10.8.2, deploying on iOS I am trying to create a timed event. My thought process was to create a thread, do the timing in it and then at the end have it call another function. This is working however it is pausing the rest of the program. //Launch a thread std::thread t1(start_thread); //Join the thread with the main thread t1.join(); void start_thread() { std::cout << "thread started" << std::endl; auto start = std::chrono::high_resolution_clock::now(); std::this_thread

问题 How do I get a timer event to fire one at a time. For example I have a timer that raises an event every 10 minutes. The event that is raised takes 10 or more minutes to finish executing. I would like the timer to reset AFTER the event has finished. In other words I do not want to raise more than 1 instance of the event at any one time. 回答1: Usually what I do is have my event stop the timer when it's raised and then restart the timer when the event process completes: private void timerHandler
