A method for fast page loading of listview in android system

Abstract

The invention relates to a ListView quick page loading method in the Android system. The ListView page loading process is split into the three large parts of the achieving of the abstract parent class of the basic general paging logic, the acquisition of the inherited child class of the load parameters for different load modes, and the specific use of the Activity class on the ListView paging load; through this method the paging load of the resources by the ListView is achieved, while the user waiting time is reduced, and resource consumption is saved. In addition, the fast transplant of the ListView page load function is achieved through packaging, when the function is needed to be used in an application, only the instantiation objects and simple operations are needed, multiple repetitions and page logic additions are not needed, the extent of code complexity is simplified, the development speed is increased, and the use of ListView is more clearly, and the ListView is easily extensible, easy to maintain and improves system performance.

Description

technical field [0001] The invention relates to a method for fast page-by-page loading of ListView in an Android system, and belongs to the technical field of ListView list optimization in the Android system. Background technique [0002] In recent years, the Android operating system has continued to develop and evolve, and smart devices equipped with the Android operating system have gradually become an indispensable tool for ordinary people every day. Among the various ways for Android devices to interact with users, displaying information in a list is the most commonly used one. Therefore, ListView has become one of the most flexible and widely used controls in the Android system. Developers can display resources to users through ListView, including displaying text, pictures, data and other types of content. For example, commonly used contact lists, Weibo information, WeChat messages, etc. are all implemented using the ListView control. [0003] Under normal circumstance...

AI Technical Summary

Problems solved by technology

This method has the following defects: 1. When the ListView list control needs to be used in multiple places in the application, it is necessary to write paging logic for each control to achieve the desired effect. bad user experience

2. If the paging strategy provided by the server changes, a large number of modifications need to be made on the client software. The operations of different strategies are mixed together, and the code complexity will lead to inefficiency, and the application program is not easy to maintain
