Android Touch gesture distribution and androidtouch gesture
In the Touch distribution in android, we often see ACTION_DOWN-> ACTION_MOVE-> ACTION_UP. When we don't know how it is distributed, we always feel confused, therefore, it is necessary to understand its overall distribution process, so it is necessary to keep a good record.
Event Distribution Function

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 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

Preface
Gestures are important for some effects. They are widely used in canvas and interaction. Let's take a look at the small program gestures.
Demo
To check whether the applet supports multiple fingers, you need to use touchstart, touchmove, and touchend.
// index.wxml
//index.jstouchstartFn: function(event){
The applet implements the gesture pattern lock function and gesture lock screen function.
Examples of this article share the code for the screen lock of the gesture pattern of the applet for your reference. The details are as follows:
