animation

问题 I am trying to create a drop-down animation. When the user taps on a specified button @+id/btnToHideView , I would like a view @+id/relativeLayoutControls to drop down/slide up ( VISIBLE / GONE ). Here is how the layout file looks: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <Button android:id="@+id/btnToHideView" android:layout_width="25dp" android

问题 Can some one please tell me why this is not animating? I feel that the code is all perfect but the animate function is not working. The button is jumping instantly from side to side but like i said it isn't animating... func moveResetButton( constraint : NSLayoutConstraint, isOffScreen : Bool) { if isOffScreen { //animate the button onto the screen UIView.animate(withDuration: 3.0, delay: 0.0, options: .curveLinear, animations: { constraint.constant += 120 }, completion: nil) } else { /

问题 I am using an artist animation method with 5 subplots. There is one static plot on the left, with 3 smaller animated imshow plots to the right (the colorbar is the 5th). I have successfully used ConnectionPatch to connect subplots to show where the data is coming from, but only on static plots. No matter what I try, I can't seem to get the patches to show up on the animation. I've tried to include the patch in the image artist list, tried to update the figure with the artist instead of the

问题 I want to do an animation in which an image continuously keeps moving from top to bottom after every 3 seconds. I have achieved this using the following code My XML file <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_gravity="left|top" android:baselineAligned="false" android:background="#ffffff"> <RelativeLayout android:layout_width="match_parent"

问题 On my little testing html page, I have 4 elements. These elements play a CSS animation when hovered over, but I would like the animation to go reverse when the user stops hovering over them. -webkit-animation-direction:alternate; didn't work. My current code is as follows: <style> div:hover{ -webkit-animation: animationFrames ease 1s; -webkit-animation-iteration-count: 1; -webkit-transform-origin: 0% 0%; -webkit-animation-fill-mode:forwards; /*Chrome 16+, Safari 4+*/ -webkit-animation

问题 In my game i have 12 different animations and each animation consist of 10 bitmaps and each bitmap is 200x150 pixel. Every time user touches to the screen(virtual gamepad) one of the animations will play. Normally this is an easy job but performance wise i am having trouble. Loading all bitmaps on an array from the beginning of the game cause to crash game because of VM memory budget problem. It seems my other option is to recreate bitmaps everytime i need and then recyle them, but this might

问题 I have this idea, in which I'd like to animate a pair of robot eyes, similar to Anki's Cozmo, but instead of displaying on a LED screen, I would like to run this in a python application, while still have a similar feel/effect (slight flickering, look pixelated). The problem here is that I have not a clue where to start. Must I have all the animation sprites for all the expressions (sad, happy, angry...) and transitions, then using tkinter or pygame. Or can I just draw directly from a set of

问题 Hello All and Merry Christmas, Could someone please explain me how the following sample of code works (http://matplotlib.sourceforge.net/examples/animation/random_data.html) ? import numpy as np import matplotlib.pyplot as plt import matplotlib.animation as animation timeline = [1,2,3,4,5,6,7,8,9,10] ; metric = [10,20,30,40,50,60,70,80,90,100] ; fig = plt.figure() window = fig.add_subplot(111) line, = window.plot(np.random.rand(10)) def update(data): line.set_ydata(data) return line, def data

问题 From doing research and asking for help I have so far built an animation moving from left to right using the code in the JSFiddle below. This loops every 20 seconds. http://jsfiddle.net/a9HdW/3/ However now I need a second image that moves from right to left and for this to automatically trigger straight after the first image has completed its animation. If you could do this that would be amazing. Thanks In Advance <canvas id="canvas" width="1600" height="300"></canvas> <script> window
