gestures

问题 In Google Glass XE16 GestureDetector can detect several gestures like LONG_PRESS, SWIPE_DOWN, THREE_LONG_PRESS, TWO_SWIPE_DOWN , TWO_TAP & SOME OTHER GESTURES. In glass TWO_SWIPE_DOWN is like shortcut option to cancel everything and go to black screen. After that black screen it comes "ok glass" . But I need to override the TWO_SWIPE_DOWN TAP so that user can not go outside the application in this way. I want to show the user specific message in the time of tapping TWO_SWIPE_DOWN. I have code

问题 I've (along with many others) have noticed that Apple changed the appearance of the popover controller to use a "slider" window rather than the usual "popover" tableview that I've used. While I'm okay with the new appearance, like others I'm having issues with the swipe gesture that is introduced: iOS 5.1 swipe gesture hijacked by UISplitViewController - how to avoid? The fix for this seems to be to set the split view controller method "presentWithGesture" to "NO." UISplitViewController

问题 I wanted to know how I would make a whole symbol (an image) scrollable? I have found out how to do the multi-touch pinch to zoom but I can't find any code samples that will let me make the image scroll vertically only with one finger. So all I want to do is make an image scroll up and down with a single finger input. Are there any simple methods or sample code anyone could give me? 回答1: There are two ways to make an image scrollable in an AS3 mobile project: using the Pan gesture (two fingers

问题 I am relatively new to Android Animation and Gestures. I have 15 images that I want to slide around. Only one image shows up on the screen at a time and when I slide L->R on the first image, the 2nd image shows up and so on - like a slideshow. I looked at the Android Gallery tutorial but I don't want the thumbnails to be shown. My understanding is to use an ImageView and keep changing the images. Is this the right way or is there a better approach to this? 回答1: That way you wont see the fling

问题 What I need to achieve here is as following 1) superimpose a transperent "dot" on the PNG image ; where user has clicked. 2) superimpose a transperent "Big circle", when user is holding touch for long. 3) upon Doble click "Clear the screen" Primarily I am using "onTouchEvent" for click-event detection... and "geastureDetector" for doubleTap detection... but not getting the desired result. These are the 2 implementations I am trying out This first approach works fine ... But the click event

问题 I want to create system overlay view, which detect gestures without blocking other apps. How can i do it (apps like OmniSwipe, Easy Swipe detect gestures without blocking anything)? Below code, which blocking other apps cause of system overlay view. package com.carxsing.anglelockscreen.GestureDetector; public class GestureService extends Service implements GestureOverlayView.OnGesturePerformedListener{ private WindowManager windowManager; private GestureOverlayView GestureOverlay,

问题 The scenario I am trying to solve is I have several UIViews as subviews of a master UIView. What I want to be able to do is highlight a views rect by lets say changing its border as a finger slides across the view..similar to what happens when you move/drag your mouse cursor over a hypertext link. 回答1: You can get the location of the touch inside your touchesMoved: method, then ask the master UIView which view was touched: - (void)touchesMoved: (NSSet *)touches withEvent:(UIEvent *)event {

问题 I have a vertically-scrolling scroll view that has a single subview. This subview has a couple of collection views. I want them to scroll horizontally. It doesn't work because they are inside the scroll view. The problem is that the pan/scrolling gesture is working just for the scroll view and it doesn't propagate to the collection views. I just see the scroll view scrolling. There is the same problem with tapping on a collection cell. This event just doesn't happen. I already tried adding

问题 I'm mocking up a wp7 app in Expression Blend and looking for set up an event handler in response to certain gestures. Some Bing-ing shows some people recommending to use "on click" or something and check the time between taps oneself, but it seems like there should be an easier way. Is there an event for Silverlight controls that fires for gestures (or specific types of gestures?) 回答1: Silverlight for Windows Phone 7 doesn't natively contain any support for gestures. However, there are a
