Event Distribution Function Public void dispatchTouchEvent (MotionEvent ev )

This paper briefly introduces the basic concept of gesture recognition and the basic method of gesture recognition, and uses the wave in eight gestures as an example to explain how to use the algorithm to identify the gesture, and then continue to introduce how to build a hand tracking class library, and on this basis, The common gestures in the remaining 7 are i

The problem of switching the interface between the left and right sides of the interface with ListView cannot be solved through the gesture. The listview gesture The interface with ListView cannot slide left or right through a gesture to switch the interface. Solution Problem description: This problem occurs when the OnGestureListener sliding window is switched.

When a drag gesture conflicts with a sweep gesture (when UIPanGestureRecognizer conflicts with UISwipeGestureRecognizer), pangesturerecognizer The story occurs in this situation: Add a drag gesture to the entire controller, and then add a left slide cleaning gesture to each Cell on the control. Then the problem arises:

Interacting with other user interface controlsUicontrol subclasses will overwrite Parentview's gesture. For example, when a user clicks on UIButton, UIButton accepts a touch event, and its parentview is not received. This applies only to the control of the default action for gesture recognition overlap, including: One finger click action: UIButton, Uiswitch, Uistepper, Uisegmentedcontrol, and Uipag

The Windows Mobile 6.5 developer kit was available in early June. It brings new features to the majority of technology enthusiasts, including widgets and gesture API. Some developers have made explorations and attempts on the widgets application, including guojing, Jack Ma, and Jack. net. Let's take a look at the example of gesture API in TDK. Before you start, you need to pay attention to the following t

This paper analyzes the application of gesture gesture recognition by Android. Share to everyone for your reference. Specifically as follows: It's nice to see the gesture recognition feature in the Android1.6 SDK, and I've been wondering how to control the role of the game by using gestures (and, more accurately, gestures) in Android for an NDS game.
