Many of the front-end events are common on the PC and browser side, but some events are only generated on the mobile side, such as touch-related eventsThis article deals with some of the common events on mobile, including native-supported click, Touch, tab, swipe events, and defined gesture gesture events (currently just a concept that needs to be encapsulated wh
This article adds: Many online gesture articles say that Android supports gestures only from SDK 1.6 (that is, API 4), but I can also identify them using SDK1.5 simulators !. (I wanted to test the support effects of lower sdks, but I didn't have sdks earlier than version 1.5... my mobile SDK 2.2-,), so I checked the Api and found that:
Android. view. GestureDetector. OnGestureListener; since api-1,
Android. view. GestureDetector; since api-1,

In iOS, you can use the system's built-in gesture recognition (Gesturerecognizer), or you can create your own gestures. Gesturerecognizer converts low-level to high-level execution behavior, the object you bind to the view, and when a gesture occurs, the view object that is bound to it responds and determines whether the action corresponds to a particular g
Today brings a right swipe to destroy the activity, activtiy with the movement of the finger to destroy, sliding destruction activity mainly Using Gesturedetector to achieve this effect, when the gesture on the screen on the slide, will fall off with the Onfling method, so, in this method to do the judgment and operation can achieve the effect we want. First look at the final effect of the implementation:6

From the API, from the beginning of the api-1 has supported the gesture and gesture listener, so many say api-4 to support this sentence is also true! Because:Android. gestureThis class is fromApi-4Is supported. This classInput Method Gesture RecognitionWill be used in
We know that in a touchscreen phone, gestures can be used to create actions. Especially with Ubuntu phones, gesture manipulation takes a lot of use. So how can you detect gestures in a QML application? I used to detect a gesture in my Flickr application. Today we use a Web-based example to do an example. This routine is more reusable.

Gesture recognition is one of the important input methods of HoloLens interaction. HoloLens provides the underlying API and high-level API to meet different gesture customization needs. The underlying API gets the position and speed information of the hand, and the high-level API uses the gesture recognizer to identify preset gestures (including, click, double-ta

adds a gesture monitoring to self. view;
PanRecognizer. maximumNumberOfTouches = 1;
PanRecognizer. delegate = self;
[PanRecognizer release];
}
Other gestures are similar.
Its core is to set the delegate and use addGestureRecognizer on the view for gesture monitoring to add the specified gesture monitoring.
Of course, remember to add

Called when the recognition of one of Gesturerecognizer or Othergesturerecognizer would is blocked by the otherReturn YES to allow both to recognize simultaneously. The default implementation returns no (by default No. Gestures can be recognized simultaneously)That means, return yes, allow both to handle gesture interaction, (if it is webview, you can add a click gesture, but do not affect the webview scrol
