本文介绍了如何解决在ADT16.0中使用ImageView时出现的[Accessibility]Missing contentDescription attribute on image警告。通过设置android:contentDescription属性为imageView提供描述性的文本，帮助屏幕阅读器和其他辅助工具更好地描述用户界面。

[Accessibility] Missing contentDescription attribute on image

今天使用了下ADT 16.0 在定义一个ImageVIew的时候总是提示这个[Accessibility] Missing contentDescription attribute on image警告，虽说可以不理但总是感觉怪怪的，在网上一搜发现原来这是ADT 16.0的新特性，在一些没有文本显示的控件里，如imageView和imageButton等，ADT会提示你定义一个android:contentDescription属性，用来描述这个控件的作用。英文原文如下，如有翻译的不对的地方，敬请批评指正。

Resolved this warning by setting attribute android:contentDescription for my ImageView

android:contentDescription="@string/desc"

Android Lint support in ADT 16 throws this warning to ensure that image widgets provide a contentDescription

This defines 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.

Non-textual widgets like ImageViews and ImageButtons should use the contentDescription attribute to specify a textual description of the widget such that screen readers and other accessibility tools can adequately describe the user interface.
