摘　　要：Android系统提供的组件不能完全满足开发人员的需求,很多组件需要通过重写View来实现。在数据可视化方面,动态折线图是一种常用的组件,它根据数据的不断变化来实时展现信息。基于此问题,提出了一种动态折线图的设计及实现方法,对数据模型、定时器、折线平滑、组件绘制等关键技术进行了详细论述。组件设计合理,使用方便,支持自定义,实时性效果良好,能满足大多数Android应用开发的需求,有一定的实际应用价值和创新性。The components provided by the Android system cannot fully meet the needs of developers,and many components need to be implemented by rewriting the View.In terms of data visualization,dynamic line graphs are a commonly used component that displays information in real-time based on the continuous changes of data.Based on this issue,a design and implementation method for dynamic line graphs is proposed,and key technologies such as data models,timers,line smoothing,and component drawing are discussed in detail.The component design is reasonable,easy to use,supports customization,and has good real-time performance.It can meet the needs of most Android application development and has certain practical application value and innovation.
