Now question is why this is needed.
现在的问题是为什么需要这样做。
Consider scenario where you have designed application which have ImageView with some image.The image carries message what it does.But there may be a blind person who can not see.So in that case if you have used contentDescription attribute then Text-To-Speech functionality will read the value so even blind person will come to for what purpose image is placed there even though he can't see it.
考虑一下您设计的应用程序的场景，其中包含带有一些图像的 ImageView。图像携带消息它的作用。但可能有一个看不见的盲人。所以在这种情况下，如果您使用了 contentDescription 属性，那么 Text-To-Speech功能将读取值，因此即使是盲人，即使他看不到图像，也会将图像放置在那里的目的。
contentDescriptiondefines text that briefly describes content of the view. This property is used primarily for accessibility. Since some views do not have textual representation this attribute can be used for providing such.
contentDescription定义简要描述视图内容的文本。此属性主要用于可访问性。由于某些视图没有文本表示，因此该属性可用于提供此类表示。
Widgets like ImageViews and ImageButtons should use the contentDescription attribute to specify a textual description of the widget such that screen readers Text-To-Speech and other accessibility tools can adequately describe the user interface.
像 ImageViews 和 ImageButtons 这样的小部件应该使用 contentDescription 属性来指定小部件的文本描述，这样屏幕阅读器 Text-To-Speech 和其他辅助工具可以充分描述用户界面。
