Class Overview
Abstract base class for a top-level window look and behavior policy. An instance of this class should be used as the top-level view added to the window manager. It provides standard UI policies such as a background, title area, default key processing, etc.
The only existing implementation of this abstract class is android.policy.PhoneWindow, which you should instantiate when needing a Window. Eventually that class will be refactored and a factory method added for creating Window instances without knowing about a particular implementation
window是一个抽象基类，负责顶层窗口显示和行为的规则。这个类的一个实例必须被用作顶层的view加入到window manager中。它提供了标准UI规则，例如：背景，标题区域，默认的主进程等等。
这个抽象类的仅有的一个实现是android.policy.PhoneWindow。当你需要一个窗口window的时候，你需要实例化PhoneWindow。最后，PhoneWindow这个类会使用你不需要知道的特殊实现方式的重构方法进行重构，从而得到一个PhoneWindow对象，也即得到一个窗口。
