问题描述

现在的问题是，对于所有不同的活动，是否仅可能有一个XML布局文件（建议）。我个人看到以下问题：
- 每个布局文件中的底数均不相同。由于我在ConstraintLayout内部使用了ScrollView，所以我不知道如何识别布局。我必须在XML布局文件中为所有ImageButtoms手动设置约束
- 我没有在每个XML布局文件中使用普通的Buttoms，而是ImageButtons。创建XML布局文件时，我必须指定要在ImageButtons上显示的图片。我不知道如何动态地做到这一点
没有人知道这是否可行以及如何做这样的事情吗？
解决方法
您可以将Stuff添加到Layout中，并在运行时完全管理布局的参数（通常在OnCreate或OnCreateView中完成（取决于是Activity还是Fragment） 只需使用AppBar等进行基本布局，然后按代码添加图像按钮即可。
