Problems solved by technology

[0003] There are roughly two types of dual-screen Android models currently on the market: one is to connect an external multimedia device through HDMI (High Definition Multimedia Interface) or WIFI (Wireless Fidelity) connection methods (such as a TV) is connected to an Android smartphone, and then through the HDMI output function, WIFI Display function, DLAN function (DIGITALLIVING NETWORK ALLIANCE, Digital Living Network Alliance) provided by the Android operating system, the multimedia content is transmitted to an external multimedia device for playback, but The functions it can realize are limited. External multimedia devices can only perform multimedia playback or simple operation functions, and cannot perform complex functions of the Android system such as running complete applications. The other is to directly use two Android devices to control two Screen, two devices are connected through USB (Universal Serial Bus, Universal Serial Bus) or network, etc. for data interaction. This solution requires two Android devices, and its cost is relatively high

Embodiment 1

[0075] Please refer to figure 1 Shown, embodiment one of the present invention is:

[0076] A method for controlling multi-screen display provided by the present invention comprises the following steps:

[0077] S1: Create a plurality of activity stacks, and the plurality of activity stacks are in one-to-one correspondence with a plurality of display screens;

[0078] S2: Obtain multiple activities corresponding to the control information on each display screen;

[0079] S3: the activity stack corresponding to the display screen manages the life cycles of the multiple activities;

[0080] The S3 is specifically:

[0081] Create a plurality of task stacks in the activity stack;

[0082] According to the type of the application program, the multiple activities are classified to obtain all activities corresponding to each application program;

[0083] The plurality of task stacks are in one-to-one correspondence with a plurality of application programs, and one task stack ma...

Embodiment 2

[0090] The difference between the second embodiment and the first embodiment is that a method for controlling multi-screen display further includes:

[0091] The default Android device establishes communication connections with multiple display screens through the multi-screen SDK interface;

[0092] Obtain the control information on each display screen through the manager of the Android device;

[0093] Judging whether different control information needs to share the same component in the Android device;

[0094] If necessary, control different control information through the Android focus and process them one by one, and then send corresponding drawing commands to the display control objects of the corresponding display screens in sequence;

[0095] If not, after processing the different control information at the same time, and sending corresponding drawing instructions to the display control objects of the corresponding display screens;

[0096] Create multiple Android s...

Embodiment 3

[0100] In the present invention, activities are managed by creating a plurality of activity stacks Activity Stack in an Android device, and the plurality of activity stacks are in one-to-one correspondence with a plurality of display screens, and an activity stack ActivityStack maintains a corresponding display screen. a plurality of activity activities; obtain a plurality of activity activities corresponding to the control information on each display screen; create a plurality of task stack tasks in the activity stack; the plurality of activity activities are based on the corresponding application type Different classifications are carried out to obtain all activities corresponding to each application; the life cycle of all activities of an application is managed through a task stack,

[0101] The plurality of task stacks are in one-to-one correspondence with a plurality of application programs, and one of the task stacks manages the life cycle of all activities corresponding ...

Abstract

The invention relates to the technical field of computers, in particular to a multi-screen display control method and system. The method comprises the following steps of creating a plurality of activity stacks, wherein the activity stacks are in one-to-one correspondence with a plurality of display screens; obtaining a plurality of Activities corresponding to control information on each display screen; managing life cycles of the Activities by the activity stacks corresponding to the display screens; and drawing Activity windows, corresponding to the Activities with the life cycles in running states, in display control objects corresponding to the display screens, thereby enabling the display screens to perform corresponding display. According to the method and the system, any Android application can be compatible without performing any change on a third-party application, and basically complete functions and operations of an Android operation system can be provided without multiple Android devices, so that the usage cost is reduced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a control method and system for multi-screen display. Background technique [0002] As one of the most popular operating systems in the world today, Android has gained a large number of applications due to its openness and complete application ecosystem, and is used on different hardware in different fields such as mobile phones, smart home appliances, and vehicle systems. However, on hardware devices with multiple physical screens (such as dual-screen cash registers, one screen facing the cashier and one screen facing consumers), most of the operating systems used are the Android system. [0003] There are roughly two types of dual-screen Android models currently on the market: one is to connect an external multimedia device to (such as a TV) is connected to an Android smartphone, and then through the HDMI output function, WIFI Display function, DLAN function (DIGITALLIVING N...
