Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be 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 scope of the disclosure to those skilled in the art.
The embodiment of the invention provides a display method of an application program interface, which is applied to an electronic device with a display screen, wherein an application program is installed in a system of the electronic device, the system of the electronic device can be an Android system (Android), after a user opens the application program, the interface of the application program is displayed through the display screen, and as shown in fig. 1, the method comprises the following steps:
step 101: a display area for displaying an application interface is determined.
Generally, a display area of an application program interface corresponds to a size of a display screen of an electronic device, and the display screen of the electronic device is the display area of the application program interface. In addition, a preset display area smaller than the actual size of the display screen can be pre-defined on the display screen of the electronic device, and the preset display area is used as a display area for displaying the application program interface.
Step 102: and judging whether the interface elements to be displayed in the display area in the application program interface at the current moment are all the interface elements of the application program interface.
Specifically, the application program interface is composed of a plurality of interface elements, and further, the types of the interface elements included in the application program interface may be the same or different. The type of the interface element may be a picture, a character, or another type for representing an application program interface, which is not limited in the present application. In a specific embodiment, the types of the interface elements in the application program interface may be both pictures, and in another specific embodiment, the application program interface includes not only the interface elements whose types are pictures, but also the interface elements whose types are texts. Generally, application interfaces include various types of interface elements.
After the display area is determined, whether the interface elements to be displayed in the display area at the current moment are all the interface elements of the application program interface is judged according to a layout file corresponding to the application program interface, wherein the layout file contains position information of all the interface elements of the application program interface, and the positions of the interface elements in the application program interface can be determined according to the position information of the interface elements. The layout file may be a file compiled using extensible markup Language (XML).
Step 103: if the interface elements to be displayed in the display area in the application program interface at the current moment are part of the interface elements of the application program interface, analyzing and instantiating the interface elements to be displayed in the display area at the current moment, and displaying the instantiated interface elements in the display area.
In the application, if all interface elements in the application program interface at the current time are not required to be displayed in the display area, that is, the interface elements to be displayed in the display area in the application program interface at the current time are part of the interface elements of the application program, only the interface elements to be displayed in the display area at the current time are analyzed and instantiated. For example, the application program interface includes an interface element a and an interface element B, the interface element a is displayed in the display area at a first time, the interface element B is not displayed in the display area, the interface element B is displayed in the display area at a second time after the first time through a sliding operation of the display screen by the user, if the current time is the first time, and the interface element to be displayed in the display area is only the interface element a at the current time, the interface element a is analyzed after the analysis, and the interface element a after the example is finally displayed in the display area, because the application only analyzes and instantiates the interface element a at the current time, and does not analyze and instantiate the interface element B, the time for analyzing and instantiating the interface element is saved, the loading speed of the application program interface is improved.
Further, after judging whether the interface elements to be displayed in the display area in the application program interface at the current moment are all the interface elements of the application program interface, if the interface elements to be displayed in the display area in the application program at the current moment are all the interface elements of the application program interface, analyzing and instantiating all the interface elements of the application program interface, and displaying the interface elements after the instantiating in the display area. For example, the application program interface includes an interface element C and an interface element D, and at the current time, the interface element C and the interface element D are both interface elements to be displayed in the display area, and then the interface element C and the interface element D are respectively analyzed and instantiated, and the instantiated interface element C and the instantiated interface element D are displayed in the display area.
In this application, after determining whether interface elements to be displayed in the display area in the application program interface at the current time are all interface elements of the application program interface, if the interface elements to be displayed in the display area in the application program interface at the current time are partial interface elements of the application program interface, the method further includes:
monitoring a sliding event in a display area;
when a sliding event is monitored, determining a newly added interface element to be displayed in the display area at the next moment of the current moment according to the sliding event;
and analyzing and instantiating the newly added interface element so that the newly added interface element after the instantiation can be displayed in the display area at the next moment of the current moment.
Specifically, if the interface elements to be displayed in the display area at the current time are only some interface elements in the application interface, the user may perform a sliding operation in the display area, and the remaining interface elements may be displayed in the display area at the next time of the current time. The sliding operation performed by the user in the display area corresponds to the sliding event in the display area, when the electronic device monitors that the sliding event exists in the display area, the electronic device indicates that the user performs the sliding operation in the display area, and then determines a new interface element to be displayed in the display area at the next moment of the current moment according to the sliding event. For example, the interface element to be displayed in the display area at the current time is interface element a, and it is determined that the newly added interface element to be displayed in the display area at the next time of the current time is interface element B according to the sliding event, then, the interface element B is analyzed and instantiated, and the instantiated interface element B will be displayed in the display area at the next time of the current time.
It should be noted that the newly added interface elements are interface elements different from the interface elements to be displayed at the current time in the interface elements to be displayed at the next time of the current time. Specifically, if the set of interface elements to be displayed at the current time is a first interface element set, and the set of interface elements to be displayed at the next time of the current time is a second interface element set, the newly added interface element is an interface element that belongs to the second interface element set and does not belong to the first interface element set. For example, the interface elements to be displayed in the display area at the next time of the current time are interface element E and interface element F, and the interface elements to be displayed in the display area at the current time are interface element E and interface element G, then the newly added interface element is interface element F. Wherein, the number of the newly added interface elements can be multiple. In addition, if no new interface element is added in the display area under the sliding operation of the user, the display content in the display area is kept unchanged.
Further, the method and the device can monitor the sliding event through a setOnScrolllingListener interface. Wherein the sliding event may be any one of an up sliding event, a down sliding event, a left sliding event and a right sliding event. For the listening of the sliding event, a specific implementation is as follows: and judging whether the sliding operation exists in the display area. When there is a slide operation, a slide trajectory corresponding to the slide operation is obtained, and the type of the slide event can be determined from the slide trajectory, specifically, the type of the slide event is determined from the coordinates of the start point and the coordinates of the end point in the slide trajectory, for example, the coordinates of the start point in the slide trajectory are (X1, Y1), the coordinates of the end point are (X2, Y2), the lower left corner of the display area is used as the origin, the right side of the display area is used as the positive X-axis direction, and the upper side of the display area is used as the positive Y-axis direction, if X1 is equal to X2 and Y1 is smaller than Y2, it is indicated that the slide event is an upward slide event, and the type of the slide event can be determined according.
In this application, for the parsing of the interface element, an parsing manner of a Document Object Model (DOM) may be adopted, specifically, before parsing and instantiating the interface element to be displayed in the display area at the current time, the layout file of the application program interface is first parsed into the Document object model, so that data information of each interface element to be displayed in the display area at the current time is respectively extracted by traversing the Document object model to realize parsing of the interface element to be displayed at the current time, and further, each interface element is instantiated according to the data information of each interface element. The document object model has a simple structure, so that the traversal is simple and the usability is strong.
Further, when the layout file of the application program interface is parsed into the document object model, the factory parser may be obtained through a system interface, document building factor.
