gestures

问题 I'm trying to get unity to recognize that I am swiping left to right, I have solved that but my issue is that it doesn't understand this till I lift my finger off the screen. My question is how would i make it so that it knows i went right and then left and then right again all without ever taking my finger of the screen Here is the code I have so far using UnityEngine; using System.Collections; public class Gestures : MonoBehaviour { private Vector2 fingerStart; private Vector2 fingerEnd;

问题 In the Android Developers gesture design section, the term "swipe" is used. In the developer section, the term "fling" is used. Are these terms synonymous? From what I have found, I believe they are, but nowhere is it explicitly said one way or the other. That said, if I want to implement functionality for a "swipe," should I implement onFling in GestureDetector ? 回答1: onFling() will get executed when a user makes a "fling" motion, and said motion has a velocity with it to determine the type

问题 I am using a mac trackpad.How to prevent the page going back and next to visited pages on horizontal scroll ?. I tried to prevent the wheel events but it doesn't works most of the time. container.addEventListener('wheel', function(ev) { ev.preventDefault(); ev.stopPropagation(); return false; }, {passive: false, capture: true}); even I tried blocking with mousewheel event which also leads to page navigation. 回答1: It has nothing to do with a webpage nor its events; this is specific system

问题 I have a parent PanResponder with a child TouchableOpacity. What happens is that the TouchableOpacity doesn't respond to clicks because the PanResponder takes the click. I have tried to follow this guide but no success: http://browniefed.com/blog/react-native-maintain-touchable-items-with-a-parent-panresponder/ this is my code: this._panResponder = PanResponder.create({ onStartShouldSetPanResponder: (evt, gestureState) => true, onStartShouldSetPanResponderCapture: (evt, gestureState) => false

问题 I would like to pinch in and out to zoom in my web view page in Flutter. I did some researches online and I found this somewhere: "Although pinch and zoom are built-in to WebView (Android) and UIWebView (iOS), they need to be "switched-on". In Android, the plugin needs to call the following: this.webView.getSettings().setBuiltInZoomControls(true); this.webView.getSettings().setSupportZoom(true); to allow pinch/zoom. In iOS, the plugin needs to call the following: self.webview.scalesPageToFit

问题 I need to handle 3 types of gestures in my app: points, lines and circles. Circles and lines are vectored (may be drawn in different directions, like in windows 8 picture password). Now I'm looking for a better way for it - read about GestureOverlayView , but, how I understood, those gestures should be given initially, and my lines will be at different angles, and circles at different diameters. Is there any easy way to do it, or better to use onTouchEvent and detect gestures mathematically?

问题 I am using the .net 4 beta 2 touch libraries, and Im trying to implement a zooming feature in my WPF application. I can get the zooming working just fine, but what I want is to zoom in on the center of the pinch gesture, and I cannot see anything in the API's about how to accomplish this. Is there some methods or properties that expose the 2 contacts being using in the pinch gesture so that I can get the center of them? EDIT: I just investigated using the GetIntermediateTouchPoints method of

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" .
