Embodiment Construction

[0029] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0030] In the prior art, the Linux system defines a variety of multi-touch events, such as: a touch start event (such as: TouchBegin), a touch update event (such as: Touch Update) and a touch end event (such as: Touch End), etc., wherein, The touch start event represents the trigger event generated when the screen is touched, the touch update event represents the event generated when the touch point moves, and the touch end event represents the event generated when the touch point disappears. Generally speaking, in addition to some basic properties of the event, each type of touch event also has three properties: touches, targetTouches and changedTouches. Each property may contain multiple touch objects (Touch objects), and each Touch object contains Contact position, size, shape, pressure and other information.

[0031]In addition, events on the Android ...

Abstract

The invention discloses a method and device for a Linux platform to support multi-point touch of an Android system, and the method comprises the steps: distributing an identification number for a contact obtained by the Linux system, judging whether the contacts are the same or not according to the position relation, judging the change condition of the contacts according to the information of an event, and displaying the change condition of the contacts. And then sending the current state of the contact to the Android system in the form of an event message of the Android system, so that accurate response of the Android system to the multi-point touch event of the Linux system is realized.

Description

technical field [0001] The invention belongs to the technical field of developing mobile applications running on a desktop operating system, and in particular relates to a method and a device for supporting multi-touch of an Android system on a Linux platform. Background technique [0002] Android compatible environment for desktop operating systems such as Linux or Windows (hereinafter referred to as Android compatible environment) is a technology for running Android applications (Apps) on Linux or Windows operating systems, which is of great significance for enriching the application ecology of operating systems. For example, an Android compatible environment running on a Linux system is generally composed of a Host and a Guest. The Host runs on a Linux system and mainly includes an Android container and a user interaction window. The role of the Android container is to isolate part of the kernel from the Linux system. Resources to support the operation of the Guest side. ...
