Multi-input device interaction method, device and medium for dual-screen different display in android system

Abstract

The invention discloses a multi-input device interaction method, device and medium for dual-screen differential display in an Android system. The distinction of the display screen; after obtaining the input device information through the system input layer, add the device type identification corresponding to the two custom bustype types in the first function, and add the event binding identification information in the event structure; monitor the underlying device Add event information, when it is judged as a peripheral input device, a pop-up window will be prompted, and the peripheral configuration will be updated to the system input layer synchronously; after the system enters the different display mode, the current same and different display modes will be updated to the system input layer at the same time ; When an event is reported by the input device of the display screen, the event is judged, and the corresponding application is started and displayed on the corresponding display screen. The present invention can support independent control on the display of the secondary screen while the secondary screen is controlled by the main screen application.

Description

technical field [0001] The invention relates to the technical field of embedded devices, in particular to a multi-input device interaction method, device and medium for dual-screen different display in an Android system. Background technique [0002] With the continuous development of technology, multi-screen entertainment and multi-screen office are becoming more and more popular, and there are more and more application scenarios of multi-screen. For example, users can connect multiple display screens in the office or home, such as computer screens, mobile phone screens, TV screens, or projector screens, to realize wireless connection between multiple display devices through a local area network. Display is also one of the connection methods, and one device is connected to two display devices at the same time, so that the two display devices can display different interactive interfaces respectively. [0003] However, in the process of research and practice of the prior art...

Problems solved by technology

[0003] However, in the process of research and practice of the prior art, the inventors of the present invention found that the original system in the prior art did not fully support the different display scenarios of dual-screen multi-input devices, and lacked a unified standard ; and the existing dual-screen different display scene is mainly used for the dual-screen scene where the main screen is responsible for display and operation, and the secondary screen is responsible for displaying the dual-screen scene. The secondary screen device is controlled by the mode of the primary screen device, and the secondary screen does not have autonomy. Part of the content displayed on the screen of the main screen device cannot be fully controlled and operated independently
