【Android】 使用ADT16出现ImageView Warning:Missing content Description attribute on image
转载自http://stackoverflow.com/questions/8500544/android-lint-contentdescription-warning
在使用ADT 16开发android程序时会发现在XML文件中定义ImageView总是会提示Warning:Missing content Description attribute on image的警告
我们可以使用添加android:contentDescription="@string/desc"的方式来解决这个问题，
具体解释参考下面的描述：
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.
