timer

问题 I'm looking to create a 60 second countdown timer bar. I've already got a text timer that counts back from 60, but I'd also like to have a visual green bar that reduces as time ticks down. I'm including two graphics to show what I'm trying to create. Can anyone point me in the right direction? Whether it's some raw code to work with or an online tutorial, it would be tremendously helpful, as I'm a bit stuck on this part of my project. Thank you kindly! 回答1: Since this is related to a previous

问题 Consider you have the following code implementation of a timer in a net game: public void DefineTimer() { Action updateClockAction = new AbstractAction() { public void actionPerformed(ActionEvent e){ //System.out.println(javax.swing.SwingUtilities.isEventDispatchThread()); JPanelMainGame.this.jLabelSeconds.setFont(new java.awt.Font("Lucida Handwriting", 1, 36)); JPanelMainGame.this.jLabelSeconds.setForeground(Color.red); JPanelMainGame.this.jLabelSeconds.setText(Integer.toString

问题 I am making a SpriteKit game in Swift. While gameState = inGame , I want the score to increase every second. How and where would I calculate and display something like this? The other answers I have found are outdated and not very helpful. There might be one I am not aware of that already exists, so I would be greatly appreciative if you could point me in that direction. Thanks for the help. 回答1: Here is a very simple way of incrementing and displaying a score every second, as you have

问题 I have already searched all day for a solution. Unfortunately, have not found anything that can help me. I have to change every 15 minutes ago values​​. I would not do in my main activity, but now a different class. I thought something like that would be no problem, but I am stuck. I wanted to print a test message, but there's something wrong with the given context. Possibly I have a general problem with my "timer". Heres my Code: Main Activity: tm = new TimerLoerg(this.getApplicationContext(

问题 I've no real idea how to do this and I have tried messing with a timer but to no avail so far. So what am I trying to do? I have a label that is blank. When a certain event is triggered I want the label to say "Competition successfully setup" for a period of 5 seconds after which I want it to return to being blank. Surely this can be done?? Can it? I have played around with a timer but I seem to be well off the mark. Any help would be most welcome. My feeble attempt is below. private void

问题 The code on the host is like this: #include<time.h> clock_t start,finish; start=clock(); ret = clEnqueueNDRangeKernel(.........); finish=clock(); double time = (double)(finish-start)/(double)(CLOCK_PER_SEC); Why is finish - start always 0? Is it because of low resolution, or is there something wrong with my timer code? 回答1: Enqueue-ing a kernel is very cheap, since the function call can return before the kernel is executed. You could use the event generated by the clEnqueueNDRangeKernel to

问题 I simply want this program to wait for a timer. All I want is for the program to pause for two seconds. I want this program to do is display "Start," wait for two seconds until the timer has finished, then display "Start, Finished Waiting, Finished." How can I make this program wait for the timer to finish? I believe that it currently creates the timer in a separate thread, not pausing the main thread, so it displays,"Start, Finished" then waits for two seconds and then displays "Start,

问题 I have an android countdown timer that is really inconsistent, and doesn't update the GUI regularly or correctly. public boolean bTimerRunning = false; public CountDownTimer timer; private long currentTime = 180000; public void onTimerTap(View v) { if (bTimerRunning) { //stop timer timer.cancel(); bTimerRunning = false; } else { //start timer final TextView etTime = (TextView) findViewById(R.id.tvTimer); //initalize Timer timer = new CountDownTimer(currentTime, 1000) { int secondsLeft = 0;
