Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a method for realizing active paging, which inherits list data, page number data, each page data, whether a pull-down refreshing instruction exists or not and the like acquired in a subclass after a BaseRecyclerViewAdapter helper. BaseRecyclerViewAdapter helper: an adapter for loading a list for populating corresponding data into a reusable view in a swipe for display of the list.
Referring to fig. 1, a flow chart of an embodiment of a method for implementing active paging according to the present invention is shown, in which active paging is mainly performed on a subclass of a BaseRecyclerViewAdapterHelper, and the method includes:
step S10, automatically increasing the number of pages to obtain the current page data. Specifically, in page editing, a flag bit for identifying a page is added by one on the basis of the last time, new page data is formed after assignment, and the page code is used for specifying a code used in a request so as to avoid messy codes generated by the acquired data.
Step S20, the number of list data corresponding to the current page data is acquired. In the above steps, the re-edited page number, that is, the current page number data, is transmitted to the obtaining module, and the obtaining module obtains the number of the list data corresponding to the current page number according to the current page number.
In step S30, it is determined whether a pull-down refresh operation is performed. If yes, go to step S40, otherwise, go to step S50.
Judging whether refreshing exists, namely two conditions exist when the first page paging is requested, wherein the first condition is automatic refreshing, namely automatic loading when the page is opened, and the second condition is that the first page data is refreshed by pulling down, so as to judge whether refreshing exists.
The pull-down refresh is specifically to release the list after the pull-down list reaches a certain displacement, the list rebounds and reloads, whether a paging request exists is judged by judging whether the pull-down refresh exists, when the pull-down refresh exists, the paging request exists is judged, the current page code data and the number of the list data corresponding to the current page code data are received, if the pull-down refresh operation exists, namely the paging request exists, the step S40 is executed, otherwise, the step S50 is executed.
In an embodiment of the present invention, please refer to fig. 2, which is a flowchart illustrating another embodiment of a method for implementing active paging according to the present invention, wherein the step S30 of determining whether there is a pull-down refresh operation further includes:
if there is no pull-down refresh operation, step S31 is executed.
Step S31, judging whether the number of the list data corresponding to the acquired current page number is more than 0; if yes, indicating that the list data needs to be loaded, executing step S32, splicing and loading the list data corresponding to the current page code data;
otherwise, indicating that no list data needs to be loaded, step S50 is performed.
In the above embodiment of the present invention, the splicing adopts an Android system method.
Step S40, the list data corresponding to the current page data is loaded and acquired. In the above steps of the embodiment, if it is determined that there is a paging request, the list data corresponding to the current page code data is loaded.
Step S50, determining whether the number of list data corresponding to the acquired current page code data is less than the displayable data number of one page, if yes, executing step S60, otherwise, executing step S70.
In one embodiment of the present invention, the step of determining whether the number of list data corresponding to the acquired current page code data is less than the displayable number of one page includes:
the number of data which can be displayed on one page is set to be M in advance, and whether the number of list data corresponding to the acquired current page code data is less than M is judged. For example, if the number of data displayable on one page is 20, it is determined whether the number of list data corresponding to the current page number is less than 20, and if the number of data corresponding to the current page number is less than 20, it indicates that the current list data is less than one page of data, and the data can be displayed on one page.
Step S60, no more data is loaded for display. In the invention, if the number of the list data corresponding to the current page code data is less than the displayable data number of one page, the current list data is less than one page of data, and can be displayed in one page without loading and displaying more data.
Step S70, load display more data. In the above embodiment, if the number of the list data corresponding to the current page code data is greater than the number of data that can be displayed in one page, it indicates that the current list data is greater than one page of data, and the current list data cannot be displayed in one page, and more data needs to be loaded and displayed.
The invention provides a method for realizing active paging, which provides a subclass inherited to a BaseRecyclerViewAdapter helper and automatically judges paging logic according to current page code data, paging requests and whether pull-down refreshing exists in the subclass. Therefore, after the list page requests the list data, only the list data, the page code data, the paging requests, the paging data quantity and whether the pull-down refreshing is performed or not need to be transmitted to the subclasses, and the operation of automatically loading the pages in the subclasses can be realized. The complex logic of realizing paging in the list page is avoided, unnecessary code writing is reduced, and the code reuse rate is improved.
Referring to fig. 3, a schematic structural diagram of an apparatus for implementing active paging according to the present invention is shown, where the apparatus includes an obtaining module 10, a determining module 20, and an executing module 30, where,
an obtaining module 100, configured to obtain current page code data and obtain the number of list data corresponding to the current page code data;
the judging module 200 is configured to judge whether a pull-down refresh operation is performed and judge whether the number of list data corresponding to the acquired current page code data is smaller than the number of data displayable on one page;
the execution module 300 loads and acquires list data corresponding to the current page code data if a pull-down refresh operation exists; and if the quantity of the list data corresponding to the acquired current page code data is less than the quantity of the data which can be displayed on one page, no more data is loaded and displayed.
One embodiment of the present invention further provides a mobile terminal, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor, and when the computer program is executed by the processor, the steps of the method for implementing active paging according to any of the above embodiments are implemented.
One embodiment of the present invention further provides a computer readable storage medium, and the computer program, when executed by a processor, implements the steps of the method for implementing active paging according to any of the above embodiments.
