Below in conjunction with the accompanying drawings the present invention is described in further detail.
According to an aspect of the invention, it is provided a kind of vehicle mounted guidance multi-screen display method.Wherein, vehicle electronic device
Including but not limited to：The smart machines such as onboard navigation system, smart mobile phone, panel computer, vehicle-carrying notebook computer.
In one embodiment, above-mentioned vehicle mounted guidance multi-screen display method can be used in smart machine, needs explanation
It is that described smart machine is only for example, if other existing or network equipments being likely to occur from now on and user equipment are suitable for
In the present invention, within also should being included in the scope of the present invention, and it is incorporated herein with way of reference.
Refer to Fig. 1, Fig. 1 is the vehicle mounted guidance multi-screen display method of the offer according to a preferred embodiment of the invention,
The method is completed by vehicle electronic device, as shown in figure 1, comprising the steps：
Step S101, acquisition need the multiple tasks run；
Multiple tasks in above-mentioned steps S101 can be：Vehicle mounted guidance task, vehicle mounted guidance is (complete using vehicle GPS
Ball alignment system) cooperation electronic chart carrying out, it can conveniently and accurately tell driver go to destination the shortest or
Person's the fastest path, is the good assistant of driver.
Automobile GPS navigation system is made up of two parts：
A part is made up of the GPS being arranged on automobile and display device；Another part is by computer controls
The heart forms, and two parts are contacted by position location satellite.
Computer controlling center is by department of motor vehicles mandate and to set up, and it is responsible for observing local specifying at any time
The dynamic and traffic conditions of the automobile of monitoring, therefore whole auto-navigation system has two big functions at least：One is automotive trace
Control function, as long as encoded GPS receiver device is arranged on automobile, no matter this automobile travels anywhere can
Indicate its place orientation by the electronic chart of computer controlling center；Another is to drive guide function, and car owner is permissible
Each regional traffic route electronic chart is stored on floppy disk, as long as onboard inserting floppy disk in reception device, on display screen
The position of this car location and current traffic behavior will be shown immediately, both can input destination to be gone, and compile in advance
Make optimal travel route, and the instruction of accepting computation machine control centre, select route and the direction of running car.
Certainly above-mentioned task can for example support the media such as radio, MP3, HD video with multimedia recreation.
Certainly above-mentioned task can also be navigation warning, meter status early warning etc..
Step S102, activate the plurality of task, and multiple tasks are added to task stack carry out registration management；
One Android function of application would generally be split as multiple Activity, and between each Activity
It is attached by Intent, and android system, the Activity of whole APP, the element at stack bottom is preserved by stack architecture
It is the promoter of whole task stack.One rational task scheduling stack is not only the guarantee of performance, even more provides the basis of performance.
When an APP starts, if there is not the task stack of this APP in current environment, then system will create one
Individual task stack.Hereafter, the Activity that this APP is started will be managed in this task stack, and this stack is also just claimed
For Task, that is, represent the set of several Activity, they are grouped together into a Task.In addition, it is necessary to special note
Meaning, the Activity in a Task can come from different APP, and the Activity of same APP is likely to not one
In individual Task.
When an Actitity starts another Activity, the new Activity starting will be as task
The top of stack, and being active, although and start its Activity and retire from political life after winning tremendous successes, be still retained in task stack,
It is in halted state, when user presses return key or calls finish () method, system can remove top Activity,
The Activity allowing below reactivates state.
Step S103, task stack is added to window manager, travels through all of task stack, be multiple tasks distribution display
ID and viewing area；
When window manager comes into operation, interaction between X server and client, window management can be re-directed to
Device.Whenever will showing a new window, this request will be redirected to window manager, and it can determine the first of window
Beginning position.Additionally, the newer window manager of major part can change the kinship of window it will usually add mark at window top
Topic row, and add ornamental framework in thereabout.This two parts all to be controlled by window manager, rather than other journey
Formula.Therefore, when user is clicked on or pulled those elements, window manager can carry out suitable action (as mobile or change
The size of window).
Window manager also is responsible for processing diagram,.When user is by window graphic, window manager can cancel window
Mapping (make its invisible), and complete suitable action, window changed and is shown as diagram.Some window managers are not supported
Diagram function.
The main target of window manager, just as its name, is used to manage window.Many window managers provide attached
Plus function, such as process click in root window for the mouse, present pane and other visualization element, process button
(such as Alt-F4 can close window), judges which application executes on startup.
The window management of Android is based on C/S model, and client is exactly application program, and service end is exactly Window
Manager services.
After Activity sets up a main window, when main window is added to Window Manager, first have to build
The agent object of vertical Window Manager, and open a Session (session：Session；Realize IWindowSession
AIDL interface), and maintain this session (Activity will be set up by this session and Window Manager and contact, this
Session is the basis of C/S system).Client by this Session, window is added in Window Manager.
One complete window concept contains View, ViewRoot, Window Manager Service, Window,
Decor View, IWindow, ISession, WindowState.
It is right that the Activity at Client end is set up by IWindowSession session and Window ManagerService
Words, and Window Manager Service passes through IWindow interface accessing Client, is delivered to Client end,
By message distribution channel, it is delivered to specific message processing function.(operation such as user input is to window pipe at first
Reason service, issues active window by window management service, then is delivered to focus step by step).
Step S104, by above-mentioned viewing area Display on the same screen multiple tasks main interface.
Multiple tasks all can be shown by the method for split screen display available by the technical scheme that the present invention provides in same display screen
Homepage, so it has the advantages that to improve user experience.
Refer to Fig. 2, Fig. 2 is the vehicle mounted guidance split screen display available side of the offer according to another preferred embodiment of the present invention
Method, the method is completed by vehicle electronic device, as shown in Fig. 2 comprising the steps：
Step S201, acquisition need the multiple tasks run；
Multiple tasks in above-mentioned steps S201 can be：Vehicle mounted guidance task, vehicle mounted guidance is (complete using vehicle GPS
Ball alignment system) cooperation electronic chart carrying out, it can conveniently and accurately tell driver go to destination the shortest or
Person's the fastest path, is the good assistant of driver.
