As an optional implementation of the disclosure in the embodiment of the present invention, based on a set general data structure, fig. 7 shows an optional process of the map interface display method provided in the embodiment of the present invention, and referring to fig. 7, the process may include:
and S100, obtaining the map binding data of the target search service.
The target search service may be any one of a plurality of search services provided by a map navigation application, and the general data structure provided by the embodiment of the present invention is applicable to the target search service; for example, the general data structure set in the embodiment of the present invention is applicable to a plurality of search services to which a target search service belongs, and specifically, the attributes of the general data structure may include preset basic attributes representing the search services and field attributes corresponding to the basic attributes, where one basic attribute may represent at least one search service, and the field attribute corresponding to the basic attribute may describe a target data structure of map binding data of the represented search service, so that the target search service belongs to the search service represented by the preset basic attributes;
for example, the general data structure provided in the embodiment of the present invention may include at least basic attributes and corresponding field attributes of search services such as a search along the way, a search by way point, and a search by destination, and the target search service may be any one of the search services such as the search along the way, the search by way point, and the search by destination.
The map binding data of the target search service may be a search result of the target search service; executing the search logic of the target search service according to the search keyword to obtain the search result of the target search service; the search result of the target search service may include: POI information matched with the search key words and corresponding navigation information. According to the search keyword, the search mode of searching for the search result of the target search service can be, for example, a voice search mode, a manual search mode, and the like.
In an example, the map binding data of the target search service may be obtained by a component of the target search service through a voice search mode, for example, the component of the target search service may obtain a voice search request, analyze the voice search request, obtain a search keyword associated with the target search service, and then execute a search logic corresponding to the target search service according to the search keyword to obtain the map binding data of the target search service; after the component of the target search service obtains the map binding data of the target search service, the map binding data of the target search service can be transmitted to the general component arranged in the embodiment of the invention;
for example, taking a search for a gas station along the way as an example, fig. 8 shows a flow diagram of obtaining a map of a gas station by searching along the way and re-navigating based on the searched gas station, and can be referred to.
Optionally, the number of the map binding points of the target search service may be multiple, and one map binding point may correspond to one POI, that is, the search result of the target search service may include the map binding points of multiple POIs; for example, when searching along the way, multiple POIs along the navigation path may be searched, each POI may correspond to one map node data (the map node data of one POI may at least include the POI information and the corresponding navigation information), and then the map node data of multiple POIs along the navigation path may be acquired at this time.
Step S110, determining a target basic attribute representing the target search service from preset basic attributes representing the search service; one basic attribute represents at least one search service, and one basic attribute corresponds to a field attribute for describing a target data structure of map node data of the represented search service.
After the map binding data of the target search service is obtained, the basic attribute of the target search service can be determined from the basic attributes representing the search service preset by the general data structure, and for convenience of description, the basic attribute of the target search service can be called as the target basic attribute; in the embodiment of the present invention, a preset basic attribute may represent at least one search service;
with reference to the foregoing description of the generic data structure, the generic data structure provided by the embodiments of the present invention may include: the method comprises the steps of presetting basic attributes representing search services and field attributes corresponding to the basic attributes, wherein the field attributes are used for describing a target data structure of map binding data of the search services represented by the basic attributes; for example, the generic data structure may include: the method comprises the steps that basic attributes of the search along the way are represented, and field attributes corresponding to the basic attributes of the search along the way can be used for describing a target data structure of the map binding data of the search along the way; for a more specific description of the general data structure, reference is made to the above description, and no further description is given to the embodiments of the present invention.
And step S120, converting the map binding data of the target search service into target data corresponding to a target data structure described by the target field attribute according to the target field attribute corresponding to the target basic attribute.
After determining the target basic attribute representing the target search service, determining the target field attribute corresponding to the target basic attribute, so that the data structure of the map bundling point data of the target search service, which is described based on the target field attribute, is converted into a data structure corresponding to the target data structure described by the target field attribute, so as to obtain the target data corresponding to the map bundling point data of the target search service, and the map bundling point data of the target search service is organized in a field attribute form;
it should be noted that the data structure of the map binding data of the target search service obtained by the search may be different from the target data structure described in the field attribute form.
In an example, the field attribute may include a field attribute name and a field attribute type, and in the process of converting the map binding data of the target search service into the target data, the embodiment of the present invention may reorganize the data structure of the map binding data of the target search service by the field attribute name and the field attribute type of the target field attribute corresponding to the target basic attribute of the target search service, so as to organize the map binding data of the target search service in the form of the field attribute;
for example, map binding data of a target search service may have more data content, and in the embodiment of the present invention, data content matched with a field attribute name of a target field attribute may be determined from the map binding data of the target search service, so that a data type of the data content is converted according to a field attribute type of the target field attribute to obtain converted data content, and then target data is generated according to the field attribute name of the target field attribute and the converted data content;
with reference to fig. 6, the data structure of the searched map binding data of the search along the way may be different from that shown in fig. 6, and in the embodiment of the present invention, data content matching with each field attribute name shown in fig. 6 may be determined from the map binding data of the search along the way, for example, data content matching a data identifier (such as a data ID) of the data content in the map binding data with the field attribute name may be determined, so that the data type of the data content is converted according to the field attribute type corresponding to the field attribute name, and further, each field attribute name shown in fig. 6 and the corresponding converted data content may form target data, so as to organize the map binding data of the search along the way in the form of the field attribute.
It should be noted that the field attribute including the field attribute name and the field attribute type is only one optional form of the field attribute, and other forms of the field attribute may also be supported in the embodiment of the present invention, and the embodiment of the present invention is not limited to the form of the field attribute.
And step S130, displaying the target data on a map interface.
Optionally, displaying the target data on the map interface can be realized by displaying the texture corresponding to the target data on the map interface; for example, the embodiment of the present invention may define a texture (the defined texture may be a preset dynamic texture or a custom texture) for the target data to obtain the texture of the target data, so as to superimpose the texture of the target data on the map interface and display the target data on the map interface; overlaying the target data texture on the map interface may be adding Overlay logic (e.g., Overlay logic) to the target data texture, so as to Overlay the target data texture on the map interface in a manner of overlaying layers.
Optionally, the style of the target data texture may be a detail bubble, and the target data texture may be displayed on a map interface by the detail bubble including the content of the target data and displaying the detail bubble on the map interface.
According to the map interface display method provided by the embodiment of the invention, basic attributes representing search services and field attributes corresponding to the basic attributes can be preset, one basic attribute represents at least one search service, and the field attribute corresponding to the basic attribute can describe a target data structure of map binding data of the search service, so that the embodiment of the invention has the capability of organizing the map binding data of different data structures in the form of the field attributes; furthermore, after obtaining the map binding data of the target search service, the embodiment of the invention can determine the target basic attribute representing the target search service, and convert the data structure of the map binding data of the target search service into the data structure corresponding to the target data structure described by the target field attribute according to the target field attribute corresponding to the target basic attribute, so as to obtain the target data, so that the map binding data of the target search service can be organized in a general field attribute mode, and then the target data is displayed on a map interface, thereby realizing the display of the map binding of the target search service on the map interface.
The embodiment of the invention organizes and displays the map binding point data of different search services through a universal field attribute form, and can reduce the condition of respectively developing map binding point components matched with the data structure of the map binding point data of each search service, thereby achieving the effects of reducing the repeatability of code development and improving the universality of map binding point display and code reusability among a plurality of search services.
Based on the map interface display method provided by the embodiment of the invention, the general component can also be provided with a display effect control component for controlling the display effect of the target data texture; in the embodiment of the invention, the display effect control component is mainly used for avoiding excessive occupation of system resources and reducing display of useless information when the number of the map nodes of the search service to be displayed is excessive by setting the display avoidance logic; by way of example, fig. 9 shows another schematic diagram of general components provided by an embodiment of the present invention, which, as shown in fig. 9, may include a data control component and a display effect control component; further, the data control component may include a base class interface and a peer display control class corresponding to each search service.
The base class interface may define attributes of the generic data structure, such as a base attribute representing a search service, and a field attribute corresponding to the base attribute;
the node display control class corresponding to each search service can inherit the basic attribute and the corresponding field attribute of the corresponding search service defined by the base class interface, so that the data structure of the map node data of the corresponding search service is organized and display control is carried out in the field attribute form;
for example, after the target search service component searches and obtains the map binding data of the target search service, the binding display control class corresponding to the target search service can obtain the map binding data of the target search service, and according to the target field attribute corresponding to the target basic attribute of the inherited target search service, the data structure of the map binding data of the target search service is converted into the data structure corresponding to the target data structure described by the target field attribute, so as to obtain the target data; and defining texture for the target data to obtain the texture of the target data, and overlaying the texture of the target data on a map interface.
The display effect control component can preferentially display target data converted from the map binding data with higher priority conditions on the map interface according to the display avoidance logic when the map binding data of the search service is excessive, so that the data quantity displayed on the map interface is reduced;
for example, the embodiment of the present invention may set the display priority conditions of the map binding data for different search services, respectively, so that when the number of the map binding data of the target search service reaches a number threshold, it is considered that the map binding data of the target search service is excessive, and the target map binding data meeting the display priority conditions may be determined from the map binding data of the target search service according to the display priority conditions of the map binding data of the target search service, so as to preferentially display the target data obtained by converting the target map binding data; specifically, if the target data is obtained by converting the target map binding data, corresponding target data textures can be superimposed on the map interface, and if the target data is not obtained by converting the target map binding data, the corresponding target data textures can be cancelled from being superimposed on the map interface, so that excessive map binding points are prevented from being displayed on the map interface, and excessive occupation of system resources and display of useless information are reduced.
Optionally, the display priority conditions of the map binding data set for different search services may be different; in one example, the display priority condition of the map binding data of the target search service may be that the distance of the POI is closest and/or the arrival time is shortest; therefore, when the number of the map binding data of the target search service reaches the number threshold, the embodiment of the invention can determine the set number of the target map binding data with the shortest distance and/or the shortest arrival time of the POI from the map binding data of the target search service; when the target data is obtained by converting the target map binding data, superposing corresponding target data textures on a map interface; and when the target data is not converted from the target map binding data, canceling the superposition of corresponding target data textures on the map interface, so that the target map binding data meeting the display priority condition is preferentially displayed on the map interface.
Optionally, taking the search along the way as an example, the content of the target data may include: the mark number, the POI name, the time increase, the mileage increase and the content meeting the display priority condition; the display priority condition may be, for example, shortest arrival time, closest distance, etc.; if certain map binding point data simultaneously accords with a plurality of display priority conditions, the contents which have the highest priority order and accord with the display priority conditions can be displayed according to the priority order (such as the priority order with the shortest arrival time and the priority order higher than the priority order with the shortest distance) of the display priority conditions of different types; for example, when a gas station is searched along the way, and the arrival time of a certain gas station is shortest and the distance is shortest, when the map spot of the gas station is displayed, the content with the shortest arrival time can be displayed, but the content with the shortest distance is not displayed.
