List view drawing method and device, terminal and storage medium

Abstract

The embodiment of the invention discloses a list view drawing method and device, a terminal and a storage medium. The method comprises the steps that generating a list view drawing request; obtainingan initial list item group according to the list view drawing request, the initial list item group comprising at least one list item, each list item comprising to-be-displayed data or null data, and an adjacent list item of the list item where the to-be-displayed data is located comprising null data; and drawing an initial list view corresponding to the initial list item group, wherein the empty data in the initial list item group is invisible in the initial list view. According to the embodiment of the invention, the empty data is set at the adjacent list item of the list item where the to-be-displayed data is located; therefore, the number of the list items in the list view and the structure of the list items cannot be changed when the list view is operated subsequently, the probabilityof collapse of the list view is reduced, and local operation of the list view can be achieved on the basis of guaranteeing the stability of the list view.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular to a method, device, terminal and storage medium for drawing a list view. Background technique [0002] The list view is the most common view on a smart terminal, especially on a mobile phone or a tablet computer. The data and style of the list view are often not fixed, and componentization is to make different styles into components. Different data corresponds to different components. Through the data array sent by the server, the smart terminal can be displayed as a list of corresponding components, so as to realize flexible arrangement and combination display. [0003] At present, there are mainly the following ways to operate the list view: 1) The page pulls down to refresh the component, clears all list data, and reuses the new data array returned by the server, but this method needs to refresh the entire list data and only at the head of ...

Problems solved by technology

[0003] At present, there are mainly the following ways to operate the list view: 1) The page pulls down to refresh the component, clears all list data, and reuses the new data array returned by the server, but this method needs to refresh the entire list data and only at the head of the list Refresh, and the scene is limited, only limited to entering the list page for the first time and pulling down to refresh the update list

2) Pull and refresh the component on the page, and add a new array behind the original array. For example, the original list view displays ABC. After loading more data DEF, the list data displays ABCDEF, but this method also needs to refresh the entire list The data is only appended at the end of the list, and the scene is also limited, limited to viewing more data

However, the disadvantages of this method are as follows: the number of array elements will change, and it is easy to cause a crash when drawing the list view (because when drawing the list view, the list view page will look up the array data according to the serial number subscript, and then draw to the component corresponding to the serial number Go up; if the elements of the array change during drawing, it is easy to cause errors in data and components, or the array overflows, for example, to draw the sixth component, but there are only 5 arrays, so it overflows, and the overflow will crash); Because the array elements have changed, the entire list view also needs to be refreshed, even if only one data is added to it
