Problems solved by technology

[0003] There are roughly two types of traditional list controls: one is that the content and format of the list items in the list control are fixed, and developers do not need to care about the display of the list item content. Fixed, usually limited to specific applications, poor scalability
Another implementation of the list control is to provide the drawing callback interface of the list item, and the developer can realize the drawing of the content of the list item, and the format of the list item is controlled by the developer. This kind of list control has high scalability, but increases developer workload

[0094] In the third embodiment of the present invention, a device for creating a list control, each list item in the list control contains at least one sub-control, such as Figure 12 As shown, the device includes:

[0095] 1) The control drawing module is used to draw all the list items contained in the list control on the current interface. Specifically, the control drawing module traverses and draws list items in the list control, and when drawing each list item, traverses and draws the sub-controls therein.

[0096] Optionally, before traversing and drawing the list items in the list control, it also includes: drawing the background of the list control; and / or, when drawing each list item, before traversing and drawing the sub-controls therein, it also includes: when the list Draws the background of the checked list item when the item is a checked list item.

[0097] 2) A control building module, configured to trigger the creation of corresponding sub-controls on the lis...

Abstract

The invention discloses a method and a device for creating a list control. The method comprises the following steps of: drawing sub-controls; and processing user interaction by dynamically creating the sub-controls to improve the working efficiency of the list control. By improvement of the conventional list control, contents of a list item are constructed by using the simple sub-controls, so the expansibility of the list control is improved, the configuration difficulty of the list item is reduced, and the working load of a developer is reduced.

Description

technical field [0001] The invention relates to the technical field of graphic user interface, in particular to a method and device for creating a list control. Background technique [0002] List-type interfaces are widely used on mobile phones. List-type controls, referred to as list controls, are often used in applications such as address book, call records, text messages, and photo albums. With the increasingly complex mobile application interface, the requirements for list controls are getting higher and higher. In addition to displaying traditional text and image information in list items, providing basic controls such as buttons and selection boxes that can interact with users has also become It is a relatively common requirement, and the content of list items in different applications is different, which puts forward higher requirements for the configurability of the list control. [0003] There are roughly two types of traditional list controls: one is that the cont...
