摘　　要：BREW是一种嵌入式开发应用平台,它提供一个高效、低成本、可扩展的应用程序执行环境(AEE),在BREW平台上开发的应用程序可无缝植入任何手持设备。通过对一款运行于手机上的地理位置信息查询软件的介绍,说明在BREW平台实现显示控制的一种算法。该算法主要是根据所提供的关键字搜索地理信息数据,将可用的地理信息读取出来,然后进行显示控制,以便把不需要显示的部分裁减掉,从而达到节省系统资源的目的。BREW is a platform for embedded development and application. A high-efficiency, low-cost and extendable environment is provided in which applications is implanted into any handed-equipments. A self-designed querying software of geographical position information that is running in mobile telephone is introduced, the displaying control algorithm based on BREW platform is illustrated. The key idea of the algorithm is to search geographical information data according to the offered keywords, and to read the geographical information, and then to carry out displaying control so that needless displaying parts is cut down, thereby the system resource is saved.
