它们之间的根本区别是什么?

What is the fundamental difference between them?

推荐答案

我将定义差异如下:

• 布局是通用的ViewGroups，直接处理图形视图.他们对可以管理什么样的孩子没有要求.
• 容器完成更具体的任务，这就是为什么他们对可以容纳多少个孩子以及哪些孩子有其他要求.因此，大多数容器都需要编写Adapter类才能表达这些要求.

• Layouts are general-purpose ViewGroups dealing directly with graphical views. They have no requirements on what kind of children they can manage.
• Containers fulfill more specific tasks, that's why they have additional requirements on how many and which kind of children they can accept. Because of that most containers require writing Adapter classes in order to express those requirements.
