问题 I've been stuck on this for a while now, and though I found a workaround I don't quite understand why it works and I should to implement it properly! There also seems to be a dearth of information on the ZoomButtonsController out there. Per other articles here, I've implemented "swipe" gesture functionality in my app. However, on a single tap, I also wanted the zoom buttons to appear programmatically. I had the GestureDetector-based OnTouchListener already for this ScrollView, and so I added

问题 I've seen that since the latest update (Windows Fall Creators Update) there exists a collection of Swipe Classes, but in the current stable release of VS ( 15.4.1 ) there isn't a way to make it work. I'm currently running the latest W10 update (1709) with Visual Studio 2017 Enterprise ( 15.4.1 ) and there's no way to make it work. I've tried to make the following example work but with no luck: https://channel9.msdn.com/Events/Windows/Windows-Developer-Day-Fall-Creators-Update/WinDev015

问题 I have a swipe functionality on my mobile page, and I want to used touchstart, touchend, and touchmove to track the swipe functionality across the device without affecting the scrolling. Here is my code. jQuery('.first-frame').bind('touchmove', function(event) { _gaq.push(['_trackEvent', 'Landing-Page', 'Swipe-Toggle-Color', '0259_2190']); }); 回答1: If it's possible to only monitor the swipeleft and swiperight events in jQuery Mobile instead, do so. Otherwise, you can set a global variable on

问题 Does the Android API expose facilities for generating touch events, for example, repeatedly simulating different gestures on the screen for testing? 回答1: Doesn adb commands will work for u or u need some kind of monkay testing tool commands ??? For adb commands u can use below shell commands... adb shell input tap x y and also adb shell sendevent /dev/input/event0 3 0 5 adb shell sendevent /dev/input/event0 3 1 29 adb shell sendevent /dev/input/event0 1 330 1 adb shell sendevent /dev/input

问题 I am trying for recognizing swipe down gesture on an imageview. I tried GestureDetector but it's deprecated now. Sample code I am using is below. But, it's not going inside onFling() method. GestureDetector gestureDetector; gestureDetector = new GestureDetector(new GestureListener()); view.findViewById(R.id.imageView).setOnTouchListener(new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (gestureDetector.onTouchEvent(event)) { System.out.println("DONE-------");

问题 Why using "pan" after rotate makes view go opposite way? It seems these two gesture are use diffrent coordinate system? Rotation use the one is rotated,and pan use the normal one? And if the view is rotated nearby 0' or 360 ',pan will be normal,and if the view is rotated more colse to 180',the "pan" will make view go opposite more. Thanks. 回答1: The point is that in your handRotate method you are assigning a rotation transformation to your view. This entails a permanent (until you modify the

问题 I am currently developing some gesture recognition in C# with Kinect SDK.So far so good, the only problem being that the gesture recognition is instant. For example: i am using a messageBox to announce when i raise my hand above my head.And if i hold the hand for 2 seconds, it will open dozens of messageBoxes announcing the gesture. Is there a way to stop this? 回答1: Darren says the truth. You need to implement a stop mechanism. Kinect is analyzing everything in real time whole time so when

问题 I have a little web gallery that I added swipe navigation to for mobile browsers. I did it with pretty simple touchstart/touchmove/touchend event tracking. The problem is that when I try to pinch zoom in the browser window it fails if any finger starts in the element I added the touch event handlers to, I'm guessing from the calls to preventDefault. Is there a way I can track the touch events for navigating my images without blocking the zoom in and out feature of the browser? I don't mind

问题 I have a question to draw a line or circle indicator after user has pan gesture (i.e. user touches and drags their finger) on iPhone. However, UIGraphicsGetCurrentContext() always returns nil, does anyone know how to implement this on iPhone? Thanks, clu @interface MyView : UIView <UIGestureRecognizerDelegate> { CGPoint location; PanIndicator *panIndicator; } @implementation MyView - (id)init { if (self = [super init]) { UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc]
