animated

问题 I'm trying to create an animated sticky menu. User loads up the page and the navigation is stationary. User then scrolls down the page and after like 500 pixels (scrolling over the original navigation), the navigation animates into the page stuck to the top using fixed positioning. I have it working now (see codepen: http://codepen.io/chrisyerkes/pen/uoFKl) however, once I scroll back up and it resets the menu's position, the next time I scroll down the page, it no longer animates in, just

问题 I have an animated GIF that loops three times. I have noticed in Firefox and Chrome (haven't checked others) that I can view the GIF once and then if I reload the page, the cached GIF is not animated at all. Is there a solution to this? Is there something about the animated GIF that I could change to prevent this from occurring? 回答1: Its a super ugly solution but you could use this if your calling the image inline, not pretty but it works! <img src="filename.gif?rand=<?=rand(1,1000);?>" alt="

问题 is there a way how to determine if the current mouse cursor is animated ? I was looking for a way how to save the current cursor some time ago. I found the DrawIconEx function which perfectly suits to my purpose. Unfortunately I don't know how do I determine if the current cursor is animated. I was hoping that if I set the istepIfAniCur parameter to 1 in case of static cursor DrawIconEx returns False but it really ignores that parameter and returns True what disallows me to use it in the loop

问题 any idea how to play a fade in animation when image loads? Now it just blinks into place. I am using NetworkImageView from the Volley toolkit. Also, is there a way to set loading and error bitmaps on the network image view without using the ImageLoader.get( .. ) ? Thanks! //EDIT : Okay, thanks to you all, but if we want to be perfectionists, we should only animate if loading from disk cache, overriding setImageBitmap would case animation to go off even if pulled from memcache what you want to

问题 I'm looking for a way to slide the keyboard into view from the right, like what happens in the Contacts application when you edit a note. My problem is that when I call [someTextView becomeFirstResponder] in viewWillAppear, the keyboard immediatly pops up with no animation. And when I call it in viewDidAppear, the view first slides in from the right (UINavigationController does the sliding), and then the keyboard slides in from the bottom. Is it possible to have the keyboard slide in from the

问题 I have two views that need to be shown modally, one after the other. This doesn't work if we dismiss and show consecutively, like this: [rootController dismissModalViewControllerAnimated: YES]; [rootController presentModalViewController: psvc animated: YES]; The second modal view simply doesn't show up. I've seen a fix that was something like this: [rootController dismissModalViewControllerAnimated: YES]; [[UIApplication sharedApplication] beginIgnoringInteractionEvents]; [self

问题 I'd like to draw an animated (geodesic) polyline in google maps, a bit like this: http://planefinder.net/route/SFO/ I found many tutorials on how to animate a symbol along a polyline, but nothing about animating the polyline itself from the source to the destination. Any hints ? Where should I start ? Any help is really appreciated. 回答1: I've had some success with the following: var departure = new google.maps.LatLng(dept_lat, dept_lng); //Set to whatever lat/lng you need for your departure
