自从我在这个应用程序上工作以来已经过了几个月。在发布之前，一切都需要完美。 现在越来越多的functunallty被实现，这就是问题所在：现在活动开始达到1000行！为什么这样，你可能会问？ 这是因为需要以编程方式设置布局。
在我的应用程序的几乎所有活动中，我们都有一个滚动视图，可以从服务器下载内容，然后将其放入foreach循环中。这使得无法在xmls中设置大部分布局。只是为了吓唬你一点：

这只是一个类中两个方法的布局。甚至都不是。
这非常不方便。这个课程不仅篇幅很长，而且读起来也很混乱，因此可以防止出现问题。
现在我的问题：
在我的许多课程/活动中处理程序化布局的最佳方法是什么？
只有一个类有布局功能，然后在需要时来回发送数据？这将使布局脱离活动，但仍然无法阅读。而且，那一个班级很容易达到10k线，这只是荒谬的......
我希望你们在我开始移动所有布局文件然后意识到这是错误之前，能够以正确的方式暗示我。
