Android 中的布局和容器有什么区别? [英] What is the difference between a layout and a container in Android?

问题描述

在android studio中，在设计部分，Layouts和Containers是分开分类的.

In android studio, in design section, Layouts and Containers are categorized separately.

它们之间的根本区别是什么?

What is the fundamental difference between them?

推荐答案

我将差异定义如下:

• Layouts 是直接处理图形视图的通用ViewGroups.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，这就是为什么它们对可以接受的孩子的数量和种类有额外的要求.因此，大多数容器都需要编写 Adapter 类来表达这些要求.

• 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.
