I. Gesture recognizersGesture recognizers is an object introduced in iOS3.2 that can be used to identify gestures and simplify custom view event handling. The base class of Gesture recognizers is Uigesturerecognizer, an abstract base class that defines the programming interface for implementing the underlying gesture recognition behavior. 6 specific

That is, the more times you use Alipay clients, the more secure you will be.

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,
From the
. gesturedetector. ongesturelistener; Since api-1,
Android. View. gesturedetector; Since api-1,
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

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
