By adopting the technology, by introducing the preset components, a developer can complete the flexible configuration of the interface of the vehicle-mounted instrument by using the preset components, so that the professional requirement of the development of the interface of the vehicle-mounted instrument on the developer is reduced; by creating interface objects to store each interface and path information thereof separately and creating basic objects to store state information of all interfaces, the calculation amount of interface instantiation is reduced, and the development efficiency of the vehicle-mounted instrument interface is improved; the interface interaction of the vehicle-mounted instrument is carried out by introducing the stack structure workflow, complex user interaction logic can be easily realized, the man-machine interaction capability of the vehicle-mounted instrument is improved, and the requirement of diversified functions of a user is met.
As one possible implementation, the plurality of components may include an image component, a text component, a button component, a layout component, and an event component; based on this, the step S102 (i.e. configuring a plurality of man-machine interaction interfaces provided by the vehicle instrument based on a plurality of preset components) may include:
(1) Based on the image components, image attributes of each human-computer interaction interface are configured.
The image attributes may include padding, scaling, tiling, and the like, which are not limited.

By configuring the animation effect of each man-machine interaction interface, the man-machine interaction experience of the user and the man-machine interaction interface provided by the vehicle-mounted instrument can be improved.
(4) Based on the layout component, the UI element layout of each human-computer interaction interface is configured.
Wherein the UI element layout includes a position and a size of the UI element. The layout components may include horizontal layout components, vertical layout components, and the like, which are not limited. For example, the UI Scale Mode attribute of a canvas (i.e., a container for accommodating UI elements) may be modified by way of writing and executing scripts, thereby adjusting the minimum and maximum positions of UI element anchors to ensure that the UI elements are properly adapted at different resolutions.
By configuring the UI element layout of each human-computer interaction interface, the human-computer interaction interface provided by the vehicle-mounted instrument can be adapted to UI element display under different screen resolutions, a developer does not need to manually calculate and adjust the position and the size of the UI element, and the interface development efficiency of the vehicle-mounted instrument is improved.
(5) Based on the event component, the interaction event and callback function of each man-machine interaction interface are configured.
The interaction event may be various events triggered by operations such as clicking and sliding performed by the user, which are not limited. A callback function is a function that passes as a parameter to another function and is called for execution when a specific interaction event occurs, i.e., the callback function is actually a function that is taken as a parameter.
By configuring the interaction event and callback function of each human-computer interaction interface, the human-computer interaction interface provided by the vehicle-mounted instrument can support the interaction function of various user operations, so that the human-computer interaction capability of the vehicle-mounted instrument is improved, the vehicle-mounted instrument can conveniently realize the user interaction logic by monitoring the interaction event, a developer does not need to manually perform related processing, and the interface development efficiency of the vehicle-mounted instrument is improved.
As a possible implementation manner, the human-computer interaction interface management method of the vehicle-mounted instrument may further include: when the vehicle-mounted instrument provides a human-computer interaction interface, the size of each UI element in the human-computer interaction interface provided by the vehicle-mounted instrument is adjusted based on the current display parameters of the vehicle-mounted instrument.
The display parameters may include, but are not limited to, a size, a resolution, and the like of the screen.
When the vehicle-mounted instrument performs interactive display of the human-computer interaction interface, the current resolution of the screen can be obtained, the current resolution is compared with the preset resolution of the human-computer interaction interface provided by the vehicle-mounted instrument, and then the size adjustment parameters (such as scaling parameters and the like) of all the UI elements in the human-computer interaction interface are determined according to the comparison result, so that the size of all the UI elements in the human-computer interaction interface is adjusted by using the size adjustment parameters, and the self-adaptive display of all the UI elements in the human-computer interaction interface under different resolutions is ensured.
As a possible implementation manner, the instantiating the human-computer interaction interfaces based on the human-computer interaction interfaces and the path information saved by the respective interface objects in the step S108 may include: analyzing corresponding human-computer interaction interfaces and path information from each interface object through a preset interface management object, loading the corresponding human-computer interaction interfaces based on the path information corresponding to each human-computer interaction interface, and then instantiating each loaded human-computer interaction interface to obtain an instantiated object corresponding to each human-computer interaction interface.
As a possible implementation manner, the storing the instantiation result of all the man-machine interaction interfaces in step S108 may include: and mapping the interface type and the instantiation object corresponding to each human-computer interaction interface into a corresponding dictionary through a preset interface management object for storage.
By the method of mapping the interface types and the instantiation objects into the dictionary for storage, when the human-computer interaction interface is instantiated, whether the instantiation object of the corresponding human-computer interaction interface exists in the dictionary or not can be rapidly judged by searching the dictionary, if yes, the fact that the corresponding human-computer interaction interface is instantiated before exists is indicated, and if not, the fact that the corresponding human-computer interaction interface is not instantiated before exists is indicated, the interface types of the human-computer interaction interface to be instantiated (i.e. the human-computer interaction interface which is not instantiated before) can be rapidly found by searching the dictionary, and then the corresponding human-computer interaction interface to be instantiated and state information and path information of the corresponding human-computer interaction interface to be instantiated are found from the basic object and the corresponding interface object according to the interface types, so that the human-computer interaction interface to be instantiated and an instantiation result is loaded. Therefore, the method for mapping the interface types and the instantiation objects into the dictionary for storage can avoid repeated instantiation of the human-computer interaction interface for a plurality of times, reduces redundant calculation of human-computer interaction interface instantiation, and is beneficial to improving the overall efficiency of human-computer interaction interface instantiation.
As a possible implementation manner, the saving, by the base object, the state information of all the human-computer interaction interfaces in the step S106 may include: saving all first interfaces called when the man-machine interaction interface is displayed through the basic object; saving all second interfaces which are called when the man-machine interaction interface is suspended through the basic object; saving all third interfaces called during the recovery of the human-computer interaction interface through the basic object; and saving the fourth interface which is called when all the man-machine interaction interfaces exit through the basic object.
Accordingly, the interface state switching of the man-machine interaction interface provided by the vehicle-mounted instrument based on the basic object according to the workflow with the preset stack structure in the step S110 may include: responding to the pop operation, calling a first interface to enable the current human-computer interaction interface provided by the vehicle-mounted instrument to be displayed, and calling a second interface to enable the last human-computer interaction interface corresponding to the current human-computer interaction interface provided by the vehicle-mounted instrument to be suspended; and in response to the push operation, calling the fourth interface to enable the current human-computer interaction interface provided by the vehicle-mounted instrument to exit, and calling the third interface to enable the last human-computer interaction interface corresponding to the current human-computer interaction interface provided by the vehicle-mounted instrument to be recovered.
By the state information storage mode and the interface state switching mode of the human-computer interaction interface, when various interaction events triggered by interaction operation between a user and the human-computer interaction interface occur, the vehicle-mounted instrument can rapidly and accurately execute complex user interaction logic without manually monitoring the interaction operation and triggering the interaction events by a developer, so that the interface development efficiency of the vehicle-mounted instrument is improved, the human-computer interaction capability of the vehicle-mounted instrument is improved, and the diversified function requirements of the user are met.
For ease of understanding, the operation of the human-computer interaction interface management method of the vehicle-mounted instrument is described herein by taking a specific application as an example as follows.
The man-machine interaction interface management method of the vehicle-mounted instrument can be written into corresponding executable scripts in advance, and the main operation flow of the man-machine interaction interface management method of the vehicle-mounted instrument is as follows, as shown in fig. 2:
step 1, a developer creates a Json file and a UIPanelType class to store the existing panel and the panel information thereof.
The panel is a man-machine interaction interface, the panel information comprises path information of the man-machine interaction interface, corresponding panels and panel information thereof can be saved by creating corresponding UIPanelType for each panel, and each created UIPanelType can be saved by creating a Json file (which can be named as UIPanelType. Json), so that needed data can be obtained from the corresponding UIPanelType of the Json file later.
And 2, starting a script by a developer, analyzing the panel and panel information thereof from the UIPanelType class of the Json file through a pre-developed UIM manager, so as to instantiate the panel and store an instantiation result.
Uimianage is the core of UI management, and a single instance mode can be used to implement uimianage with globally only one UI management class. Uimianager is used to: analyzing all panels and panel information thereof, loading the panels for instantiation to create instance objects, storing related information of all panels in a dictionary form and storing all the displayed panels in a stack structure management mode.
In order for the uimianager to manage and save all the displayed panels in a stack structure, a stack structure for storing the panels may be developed in advance for the uimianager, and a pop operation and a push operation may be defined.
And 3, storing interface states of the panels through the pre-developed BasePanel public base class.
The base classes (i.e., interface states) of the individual panels can be managed by developing a BasePanel common base class, and four functions are defined in the base class of each panel: the OnEnter function called when the panel is entered, the OnPause function called when the panel is stopped (e.g., the interaction of the mouse with the panel is stopped), the OnResume function called when the panel is restored to use (e.g., the interaction of the mouse with the panel is restored), and the OnExit function called when the panel is exited. All panels need to inherit the basePanel base class, and finally mutual jump among the panels is realized.
Based on the step 3, related interaction logic may also be defined for interface state switching. For example, the interaction logic may include: the mouse only allows interaction with one interface, and after one interface is displayed, the interaction with the mouse is stopped by the previous interface; performing Push operation (calling a Push function), displaying a current interface (calling an OnEnter function), stopping a previous interface (calling an OnPause function) and storing the previous interface to the top of the stack; and (3) carrying out a Pop operation (calling a Pop function), exiting the current interface (calling an OnExit function), taking the last interface out of the stack top and recovering the last interface (calling an OnResume function).
Referring to fig. 3, the main flow of interface state switching is as follows:
when the user operation triggers the display container to appear, calling the OnEnter function to display the current interface (recorded as interface 1); when the user operation triggers the exit event of the current interface to occur, invoking an OnExit function to remove the interface 1, and displaying the content of the interface 1 no longer by the container; when a stopping event of the user operation triggering interface 1 occurs, calling an OnPause function to pause the presentation of the current interface, and calling an OnResume function to resume the presentation of other interfaces (recorded as interface 2); when a user operation triggers a resume event of the current interface to occur, an OnResume function is invoked to resume presentation of the current interface, and an OnPause function is invoked to pause presentation of interface 2. The presentation, restoration and removal of the different interfaces forms a cyclic workflow.
The man-machine interaction interface management method of the vehicle-mounted instrument brings the following to development of the vehicle-mounted instrument
The beneficial effects are that:
1) And the UI design is simplified, and the UI development efficiency is improved. By adopting the idea of componentized design, the UI design is more flexible and efficient by abstracting various UI elements into components, and a developer can modify the behavior and appearance of the UI elements by adding, removing or modifying the components without rewriting or modifying a large amount of codes, thereby reducing complicated manual coding steps and accelerating the development speed.
2) And supporting the self-adaptive display of the multi-platform resources. The content display is carried out by adopting the fixed resolution ratio by the general vehicle-mounted HMI (Human Machine Interface) and the human-computer interface management method of the vehicle-mounted instrument, compared with the general vehicle-mounted HMI, the content display of the vehicle-mounted instrument can be ensured to be adaptive to different equipment and screen resolutions, and further, UI resources on different platforms can be ensured to be displayed in a self-adaptive mode through the vehicle-mounted instrument, so that the user experience of the vehicle-mounted instrument is improved.
3) Powerful interactive functions are supported. Through the relevant configuration of interaction events and interaction operations, the vehicle-mounted instrument can provide rich UI interaction functions, so that a developer can easily realize complex user interaction logic, the man-machine interaction capability is improved, and the diversified function requirements of users are met.
4) And the expandability is strong. A flexible UI architecture is provided for a developer, the developer is allowed to expand and customize according to specific project requirements, the UI architecture has good expansibility, and the developer can conveniently add new components or functions according to own requirements.
