为适应当前移动设备用户界面可用性和可复用性需求, 解决移动设备用户界面描述语言 (UIDL) 未考虑移动设备的固有属性且对于大粒度的模式构件不能较好的支持等不足, 设计一种基于可扩展标记语言的移动设备用户界面描述语言PXMUL, 并给出基于模式组件的移动用户界面的实现框架, 从界面布局、逻辑和环境3个模块定义描述界面所需的属性, 在大粒度构件基础上实现用户界面的设计与开发.实例评估结果表明, PXMUL能够实现移动设备用户界面的可行性与有效性, 同时降低学习成本, 缩短开发周期.%In order to adapt to the current mobile device user interface usability and reusability requirements and colve the insufficency that the mobile device User Interface Description Language (UIDL) does not consider the inherent properties of the mobile device and does not support the large-grained mode components, this paper designs a mobile device user interface description language based on eXtensible Markup Language (XML) which is called PXMUL, and gives an implementation framework of mobile user interface based on pattern component.The attributes needed to describe the interface are defined from three modules of interface layout, logic and environment, and the design and development of user interface are realized on the basis of large-grained components.Example evaluation results show that PXMUL can reduce the learning cost and shorten the development cycle while ensuring the feasibility and effectiveness of interface implementation.
