android - Missing contentDescription attribute on image how to remove this warning? -


accessibility missing contentdescription attribute on image

<imageview     android:id="@+id/imageview1"     android:layout_width="34dp"     android:layout_height="61dp"     android:layout_marginleft="11dp"     android:layout_marginright="0dp"     android:layout_margintop="11dp"     android:background="#ff3333"     android:src="@drawable/arrows" />

you can use layout editor's tools or set android:contentdescription null.

here's example:

// don't need framelayout,  // tell layout editor "ignore" in layout's parent  <framelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     tools:ignore="contentdescription" >      <imageview         android:id="@+id/imageview1"         android:layout_width="34dp"         android:layout_height="61dp"         android:layout_marginleft="11dp"         android:layout_marginright="0dp"         android:layout_margintop="11dp"         android:background="#ff3333"         android:src="@drawable/arrows" />  </framelayout> 
<imageview     android:id="@+id/imageview1"     android:layout_width="34dp"     android:layout_height="61dp"     android:layout_marginleft="11dp"     android:layout_marginright="0dp"     android:layout_margintop="11dp"     android:background="#ff3333"     android:contentdescription="@null"     android:src="@drawable/arrows" />

but better should consider adding short string accurately describe imageview for.

from docs:

defines text briefly describes content of view. property used accessibility. since views not have textual representation attribute can used providing such.

must string value, using '\;' escape characters such '\n' or '\uxxxx' unicode character.
