You need to understand your app's architecture first. 您需要首先了解应用程序的体系结构。 You need to analyse the flow of UI screens and the underlying logic they perform. 您需要分析UI屏幕的流程及其执行的基本逻辑。 If you want to navigate through your activities using Navigation Drawer, well, then converting all of them them into fragments isn't a solution! 好吧，如果您想使用导航抽屉浏览活动，那么将它们全部转换成片段不是解决方案！ First find out which screens can perform flawlessly if you replace them with fragments and then go ahead with it. 首先，找出用碎片替换屏幕后，哪些屏幕可以完美运行，然后继续进行操作。 If you are new to android programming then visit Udacity online and watch all of their android tutorial videos! 如果您不熟悉android编程，请在线访问Udacity并观看其所有android教程视频！ They have a bunch of comprehensive ones and the best part - it's free. 他们有一堆综合的东西和最好的部分-它是免费的。
