How to fix a warning in android layout.xml: "missing contentDescription"

Question

<ImageView style="@style/LoaderPrevNext.Next" />

using styles

<style name="LoaderPrevNext">
    <item name="android:layout_width">40dp</item>
    <item name="android:layout_height">80dp</item>
    <item name="android:layout_weight">0</item>
    <item name="android:scaleType">fitXY</item>
</style>

<style name="LoaderPrevNext.Next">
    <item name="android:src">@drawable/next_page</item>
    <item name="android:contentDescription">@string/img_desc_next_page</item>
</style>

annoying me with a warning [Accessibility] Missing contentDescription attribute on image.

It disappears if I move or copy the description of the content from the style to the ImageView tag, but since src is defined in the style, I would like to save them together.

Guess this is just an SDK bug, but some might get a workaround ...

Clarification: The ImageView in question has a content description defined in the style of LoaderPrevNext.Next. The warning is false. I'm not interested in ideas on how to establish a description of the content or how to crack it.

The same goes for the @string resource. Just do not put the description of the image in style. Leave @string. When necessary, change this line.

To disable the warning about the missing content description in the whole project, add it to yourbuild.gradle

android {
    lintOptions {
        disable 'ContentDescription'
    }
}
