Problems solved by technology

[0003] The development tools provided by the Android system are only suitable for the display of 2-level lists. In order to achieve the purpose of multi-level display, most of the existing methods are to display multi-level lists by using ordinary system nesting. This display method is The multi-level list is nested and stored according to its own level. When displaying, all levels need to be traversed from top to bottom until the level to be displayed is found. This method reduces the speed and efficiency of display. At the same time, When it is necessary to modify the content of the multi-level list itself, the difficulty and complexity of the modification is greatly increased due to the nesting of levels

Abstract

The invention relates to a multilevel list display method for an Android system. The method includes the following steps of encapsulating and storing all to-be-displayed data in a multilevel list in a classified mode so as to obtain encapsulated data, a list data storage set, and a list data display set; updating the list data display set according to requirements of a user, and displaying the updated list data display set so as to achieve hierarchical list displaying which meets the user requirements. Compared with the prior art, the multilevel list display method has the advantages of being fast in displaying speed, high in displaying efficiency, convenient to implement and the like.

Description

technical field [0001] The invention relates to the field of system development, in particular to a multilevel list display method for an Android system. Background technique [0002] With the development of the Internet era, business needs emerge in an endless stream, and the existing controls on the APP side can basically not meet the current development needs. The content becomes more and more complex, so there are more and more multi-level presentation forms, and the levels can reach up to 5 or 6 levels. [0003] The development tools provided by the Android system are only suitable for the display of 2-level lists. In order to achieve the purpose of multi-level display, most of the existing methods are to display multi-level lists by using ordinary system nesting. This display method is The multi-level list is nested and stored according to its own level. When displaying, all levels need to be traversed from top to bottom until the level to be displayed is found. This ...
