有可能是一个非常基本的解释，但我会AP preciate几个指针都是一样的。谢谢

推荐答案

活动是用于执行一些任务的用户界面，以及更接近你可能会觉得作为一个表格或窗口其他框架。 A 查看是窗口的自我控制的矩形截面的相互作用可发生在，并且是用户界面的很多低级别再presentation。这是更接近你可能会觉得当你听到控制或控件在不同的框架。

An activity is a user interface for carrying out some task, and is closer to what you might think of as a Form or Window in other frameworks. A View is a self-controlled rectangular section of a window that interaction can occur in, and is a much lower-level representation of UI. It's closer to what you might think of when you hear Control or Widget in a different framework.

一个窗口的视觉内容是由次，这是从基View类派生的对象层次结构提供。每个视图控制窗口内的矩形空间。父视图包含并组织其子项的布局;叶的观点，在层次结构的底部，实际绘制在他们控制的矩形，并响应用户的操作。因此，一个观点就是与用户活动的互动确实发生。

The visual content of a window is provided by a hierarchy of views, which are objects derived from the base View class. Each and every view controls a rectangular space within the window. A parent view contains and organizes the layout of its children; leaf views, at the bottom of the hierarchy, actually draw in the rectangles they control and respond to user actions. Thus, a view is where an activity's interaction with the user actually takes place.

您可能会想读 Android的基础 ;这是Android的文件中一个很好的起点。

You'll probably want to read Android Fundamentals; it's a good starting point in the Android documentation.
