I am getting warning as "[Accessibility] Missing contentDescription attribute on image" for imageview. while using android lint
What does that mean?
685
When using an ImageView , ImageButton , CheckBox , or other View that conveys information graphically, use an android:contentDescription attribute to provide a content label for that View . A content label sometimes depends on information only available at runtime, or the meaning of a View might change over time.
The content description attribute links a text description to a control, ImageView, or other focusable object that otherwise has no text content. These objects wouldn't be accessible without some some sort of label or description.
Like ALT in Websites, in Android you can use contentDescription attribute in your ImageViews. This property is used primarily for accessibility.
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.
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.
