摘要
基于存在Android系统控件不能完全满足开发人员需求的情况,提出一种自定义通用可视化控件,介绍了基于Android开发的UI设计原理和图表的实现方法,着重讨论了该自定义控件中使用的AsyncTask异步任务机制.控件包括圆形图、柱状图和折线图三个图表,其中圆形图可以动态地显示.应用实验表明,该控件修改简单,使用方便,具有较强的通用性.
Since Android system components cannot fully meet the needs of developers, this paper proposes a custom general visual component, introduces the UI design principles based on Android and the realization methods of tables, and mainly discusses the asynchronous task mechanism used in the custom component. This component includes a circular diagram, a histogram and a line chart, and the circular diagram can display dynamically. Experimental results show that the component is simple and easy to use, and also has a strong commonality.
