Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals denote the same or similar parts in the drawings, and thus, a repetitive description thereof will be omitted.
Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details, or with other methods, components, devices, steps, and so forth. In other instances, well-known methods, devices, implementations or operations have not been shown or described in detail to avoid obscuring aspects of the invention.
The block diagrams shown in the figures are functional entities only and do not necessarily correspond to physically separate entities. I.e. these functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.
The flow charts shown in the drawings are merely illustrative and do not necessarily include all of the contents and operations/steps, nor do they necessarily have to be performed in the order described. For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.
In an electronic map application, under the scenes that a user clicks a Point Of Interest (POI) Point or searches and the like, some display forms Of a user interface exist in the interactive operation process Of the user, the display forms are often bound with certain specific places, and the display forms bound with characteristic places can be called follower layers. The map rendering engine of the electronic map application can be used for rendering each layer of the map, and the advantage of rendering the UI by using the map rendering engine is as follows: the following performance of the UI is very good when the user moves pictures, drags and the like.
In one technical scheme, a map engine provides a set of UI framework, and for a UI with a high following requirement, an API (Application Program Interface) provided by a map engine layer is used to design and realize UI information display. Referring to fig. 2, in order to ensure the followability of the UI, the UI frame provided by the map rendering engine is used to perform UI rendering, and an application developer needs to perform UI layout and content update according to the interface frame provided by the map rendering engine to control the display and hiding of the followability layer.
In step 210, an operation event of the geographic information point initiated by the user is received, and the operation event can be a map clicking operation or a searching operation.
In step 220, the application developer designs layout styles for displaying the information in advance, dynamically updates the displayed information content according to the information of the geographic information points, and transmits the information to the map rendering engine framework for processing.
However, rendering a UI using a map rendering engine has the following disadvantages: because the map engine needs to design a more complex UI framework to support the layout requirement of the complex UI, an application developer needs to learn the use of the UI framework of the map engine and realize the development and maintenance of the UI framework of the map rendering engine with higher difficulty. In the implementation of the electronic map application software, another set of rendering engines, namely, a UI rendering framework provided by an operating system, exists. The advantage of using the UI framework of the operating system is that the development and maintenance are simple, and an application developer can select new characteristics provided by using the UI framework according to the continuous iteration upgrade of the version of the operating system to develop a more attractive and easy-to-use map UI.
Based on the above, in an exemplary embodiment of the present invention, a layer display method is provided. Fig. 3 shows a flowchart of a layer display method according to some example embodiments of the present invention. Referring to fig. 3, the layer display method may include the following steps:
step S310, receiving a target layer display event initiated by a user;
step S320, generating a first layer through a graphical user interface of an operating system based on the target layer display event;
step S330, rendering the first layer through a map engine and generating a second layer; and
step S340, displaying the first layer and the second layer in an overlapping manner, where the first layer is located on an upper layer of the second layer.
According to the layer display method shown in fig. 3, on one hand, the first layer is generated through the graphical user interface of the operating system, and for the UI which needs to follow the map change, the application developer can design and develop according to the UI framework provided by the operating system, so that the development difficulty is reduced, and the flexibility and expansibility of the program design are enhanced; on the other hand, the map engine is used for rendering the first layer and generating the second layer, so that good following performance of the layer can be realized, and the design and maintenance cost can be reduced because the complex UI frame design of the map engine is not needed; on the other hand, the first layer is superposed on the second layer for superposition display, so that the event response can be realized through the first layer, and meanwhile, the good following performance of the layer can be realized.
Next, a layer display method in the exemplary embodiment of fig. 3 will be described in detail.
In step S310, a target layer display event initiated by a user is received.
In the example embodiment of fig. 3, when a user clicks on a geographic location point, such as a point of interest, on an electronic map, the electronic map client may receive a user-initiated point of interest click event. For example, when a user clicks on a certain building on an electronic map, the electronic map client receives the building click event initiated by the user.
The target layer display event is an event triggering the display of the target layer. It should be noted that the target layer display event may be not only an interest point click event, but also a search event, a long-press map event, a push message event of a long connection channel, such as background operation recommendation data, and may also be a layer display event of a type of interest point, such as a personal scenery point type layer display, a gourmet type layer display, a hotel type layer display, and the like, which is not particularly limited in this disclosure.
In step S320, a first layer is generated through a graphical user interface of an operating system based on the target layer display event.
After receiving the target layer display event, the electronic map client may generate a first layer through a graphical user interface of an operating system based on the target layer display event. The operating system may be an android operating system and an IOS operating system installed on the mobile terminal, may also be a Windows operating system and a Linux operating system installed on a notebook or a desktop, and may also be an embedded operating system such as a vehicle-mounted operating system, which is not particularly limited in this disclosure.
The graphical user interface of the operating system may be a user interface framework or a graphical user interface corresponding to the operating system, for example, in an android operating system, the graphical user interface is an android graphical user interface system, and in an IOS operating system, the graphical user interface is an IOS graphical user interface.
In step S330, the first layer is rendered by a map engine and a second layer is generated.
The map engine is a set of function libraries which can provide driving and managing geographic data and realize functions of rendering, querying and the like, and the electronic map is an application constructed on the map engine.
In the example embodiment of fig. 3, the first layer may be rendered and the second layer generated by a rendering engine interface of a map engine. Further, a bitmap of the first layer may be generated through a graphical user interface of the operating system, and the bitmap of the first layer is rendered through the map engine and the second layer is generated.
In step S340, the first layer and the second layer are displayed in an overlapping manner, where the first layer is located on an upper layer of the second layer.
In the example embodiment of fig. 3, the first layer and the second layer are displayed in an overlapping manner at the same screen position, and the first layer is located on the upper layer of the second layer. Further, the transparency of the first image layer may be set to be fully transparent, and the fully transparent first image layer may be superimposed on the second image layer for display.
In addition, a bitmap of the first layer can be generated through a graphical user interface of an operating system, and the bitmap of the first layer is rendered through a map engine to generate a second layer. Because the map rendering engine only needs to process drawing according to the incoming pictures, the design and maintenance cost of the map rendering engine is further reduced.
It should be noted that the layer display method in fig. 3 may be applied to electronic map software, and may also be applied to navigation software. The electronic map software or navigation software can be installed in a mobile terminal or a fixed terminal with a touch screen, such as a car navigator, a portable navigator, a mobile phone or a tablet computer, a desktop computer, and the like.
Fig. 4 is a flowchart illustrating a layer displaying method according to another embodiment of the present invention.
Referring to fig. 4, in step S410, a geographic location point click event or a search event initiated by a user is received, for example, the user clicks an interest point on an electronic map, for example, a tourist attraction, such as the beijing olympic park in fig. 7.
In step S420, a first UI of the information to be presented of the point of interest is generated through the UI framework of the operating system.
When a user clicks an interest point on an electronic map, basic information of the interest point, such as geographic location information and/or description information, the geographic location information may be latitude and longitude information, and the description information may be a description of a name, a level, a distance, and the like of the interest point, such as beijing olympic park, five star level, 8.2km, and the like in fig. 7.
After the information of the interest point is acquired, the longitude and latitude information of the interest point is converted into the coordinate information of a screen, and the description information of the interest point is displayed through a UI frame of an operating system based on the coordinate information. Further, the description information of the point of interest may also be added to the corresponding position of the first UI, e.g., the card in fig. 7, through an interface provided by the UI framework of the operating system.
In step S430, a bitmap of the first UI is generated through an interface provided by the UI framework of the operating system, and the bitmap and the coordinate information of the point of interest are transferred to the map engine.
In step S440, the transparency of the first UI is controlled to be set to a fully transparent display while the bitmap transferred to the map engine is displayed, and the first UI is displayed superimposed on the bitmap for display. After the display is superimposed, the receiving user may wait for an interaction event such as clicking on a point of interest.
It should be noted that, in the example embodiment of fig. 4, in step S440, the transparency of the first UI may not be specially set, that is, the transparency of the first UI may not be set to be a fully transparent display, and the first UI generated in step S420 may be directly displayed superimposed on the bitmap.
The example embodiments of fig. 3 and 4 demonstrate how an electronic map displays a following layer when in a static state using the layer display method of the example embodiments. The following describes in detail a process of implementing a follow-up layer display according to a layer display method in an example embodiment when a map operation event such as a map moving, a map dragging, and the like is performed on an electronic map according to fig. 5 and fig. 6.
Fig. 5 illustrates a flow diagram of a layer display method according to some embodiments of the invention.
Referring to fig. 5, in step S510, a map operation event initiated by a user is received, and the map operation event may include: a map move event, a drag map event, a zoom in event, a zoom out event, a rotate event, a slide event, and a pitch adjust event, among others.
In step S520, hiding a first layer of a target layer in response to the map operation event, where the target layer includes a first layer and a second layer, where the first layer is a layer generated through a graphical user interface of an operating system, the second layer is a layer generated by rendering the first layer through a map engine, and the first layer is located on an upper layer of the second layer.
According to the example embodiment of fig. 5, when the electronic map is operated, the display hiding relationship of the first layer changes accordingly, so that good follow-up display can be obtained.
Further, when the map operation event is finished, determining the display screen coordinates of the interest points corresponding to the target map layer; determining the display position of the first layer through a graphical user interface of an operating system based on the display screen coordinates; and displaying the first image layer based on the display position.
Fig. 6 is a flowchart illustrating a layer display method according to another embodiment of the present invention.

In step S620, the map engine notifies the UI framework of the electronic map application of the user operation start event.
In step S630, the UI framework of the electronic map application sets the first UI to a hidden state after receiving the notification of the start of the map operation event, and at this time, displays only the bitmap generated by the first UI on the electronic map, which is rendered and displayed by the map rendering engine together with other data of the map.
In step S640, upon the map operation event ending, the map engine notifies the UI frame of the electronic map application of the user that the map operation event ended.
In step S650, after receiving the notification of the end of the map operation event, the UI frame of the electronic map application recalculates the screen coordinates of the point of interest according to the longitude and latitude coordinates of the corresponding point of interest, resets the coordinate values of the display position of the first UI through the interface of the UI frame of the operating system, and displays the first UI on the upper layer.
Further, it may also wait to receive a further operation of the user, such as a favorite operation event on a point of interest, for example, clicking a favorite button to add the point of interest to the map favorite.

Referring to fig. 7, the upper layer of the card information shown in fig. 7 shows a first UI generated according to a UI framework of an operating system, and the lower layer shows a bitmap generated by the first UI rendered by a map engine, and the first UI and the bitmap of the first UI have the same display effect, so that the user feels like a card is displayed when the first UI and the bitmap of the first UI are displayed in a superimposed manner.
