摘要
概述Android应用开发中代码层次上性能优化的常规机制,然后通过一个典型案例详细阐述对ListView组件进行性能优化的三种解决方案,其中包括性能瓶颈的分析、具体的优化步骤和优化结果的测试与分析,最后对其他一些特定场景下ListView组件的优化方法作简要的介绍。使用TraceView性能分析工具对优化前后的程序进行多次测试实验,实验结果表明优化方案的实施显著提高程序的性能,提升程序的运行效率。
Outlines the general mechanism of code level performance optimization in Android application development, and then elaborates the three solutions to the performance optimization of ListView components, including the analysis of the performance bottleneck, the specific optimization steps and the test and analysis of the optimization results, and finally gives a brief introduction to the optimization method of ListView components in some specific scenarios. Uses TraceView performance analysis tool to test the program. The experimental results show that the optimized scheme can significantly improve the performance of the program and improve the operating efficiency of the program.
