The Research Of Android Graphics Drawing In The Vehicle Real-time Information Display System

With the promotion and development of the Android platform, Android applicationsbecome more and more colorful, the requirement of graphics and image processing arealso showing the individuation and diversification in development. It also formed its ownunique style and characteristics gradually.This paper discusses the application framework of the graphics and image processing on Android platform, gives a geometry processing algorithm of the virtual dashboard and implements this algorithm; It implements drawing functions for line chart and bar chartbased on AChartEngine graphics framework; The image processing algorithm based onMatrix and screen switching technology based on ViewPage are studied.And also gives the methods of adaptation which in different specifications of mobile phone screen in thispaper. At the same time, all kinds of virtual car dashboard, driving distance line chart,3Dinterface switching effect, mobile phone screen adaptation of different models are realized with above achievements in the vehicle real-time information display system, defines and encapsulates the classes and interfaces, and tests the function with object-oriented method.The interface design of the system is user-centered and realized by XML technology,ensure the operability, interactivity and fluency of the interface, the effect of a variety ofinterface allows users to experience more richer.The vehicle real-time information display system is oriented to the new growth pointof automobile service market, based on mobile terminals, provides car users personalizedservice, it has good application and promotion value. Meanwhile, rich graphics and imageprocessing algorithms have stronger portability and technical reference for developers.
