问题描述
一个为Android SDK插件在Eclipse的最新更新推出了很多新的警告你的布局和这样的。其中之一是，如果你没有在 Android的出现辅助功能警告：contentDescription 标记集。这导致我的项目之一警告的数百的，这自然使得很多困难，我发现其他更多的是的警告。
One of the latest updates for the Android SDK plugin in Eclipse introduced a lot of new warnings for your layouts and such. One of these is an accessibility warning that appears if you don't have the android:contentDescription tag set. This resulted in hundreds of warnings in one of my projects, and that naturally makes it a lot harder for me to find other more important warnings.
纵观official文档，似乎这个标签是pretty的从最终用户的角度来说毫无用处。下面是它的介绍：
Looking at the official documentation, it seems that this tag is pretty useless from an end-user's perspective. Here's the description of it:
定义文字简要介绍了视图的内容。此属性主要用于辅助功能。由于某些观点不具备文字重presentation这个属性可以用来提供这样的。
因此，基本上，我的问题是什么是标签的目的？它似乎只服用注意力从真正的错误/警告，我实在不明白怎么能说是一个辅助警告，如果它不影响用户的使用。
So basically, my question is what's the purpose of that tag? It only seems to be taking focus away from the "real" errors / warnings, and I don't really see how it can be an accessibility warning if it doesn't affect the user.

For some disabled people that tag almost similar to the "alt" tag in HTML, therefore it IS useful to the end user. Effectively it will allow a textual description to be presented to the user of what they may not be able to see clearly/interact with.
