摘要:针对在Android移动设备实现具有"多图层"管理功能的绘图软件的过程中,位图(BitMap)过度占用内存资源导致出现卡顿与尾随的现象,甚至出现OOM(Out Of Memory)错误,提出一种"三层"管理机制,不仅实现"多图层"管理功能而且确保绘图操作流畅。通过设计"画笔"类与内部数据结构,将包括坐标在内的用户绘图数据保存至XML格式的文件,达到跨平台共享数据的目的,不仅提高了互操作能力,同时改善了基于Android平台的移动学习系统性能。
During the process of implement ing drawing software with u mul ti-layer^ management on Android mobile devices, BitMap over-occupied memory resources results in caton and trailing phenomena, and even OOM (Out Of Memory) errors. Therefore, we presented a kind of “ tri-layer” management mechanism that not only to achieve the “multi-layer” management function, but also ensured the smooth operation of drawing operation. We designed the “brush” class and the internal data structure, including the coordinates of the user to save the data to the XML format file, so as to achieve the purpose of sharing data across platforms. Our approach can not only improves the interoperability, but also improves the performance of a mobile learning system based on Android platform.
