Design for Focus Navigation (Directional D-Pad, & Keyboard) Enabling view focus That just increases the noise a user needs to navigate in order to pull useful information from your interface. For instance, don't set an application icon's content description to 'app icon'. tContentDescription(contentDescription) Don't overdo your labelsĪvoid the web-developer pitfall of labelling everything with useless information. String contentDescription = 'Select ' + strValues To edit the content description at runtime, use the setContentDescription() method:

setContentDescription()īase the content description on some context, such as the state of a toggle button, or a piece of selectable data like a list item. Labels that won't change while using the app (such as 'Next' or 'Purchase') can be added via the XML layout by setting a UI element's android:contentDescription attribute: Even though both disappear as the accessible name once text is typed into the field the hint comes back into view when the field is emptied and it will be read again by TalkBack, not the case for contentDescription on EditText controls.ĭevelop - Training - Implementing Accessibility - Developing Accessible Applications | Android Developers Add Content Descriptions Static Labels Use XML layout android:contentDescription This is a reason why a hint is a better option. When the field is filled, TalkBack reads the entered content to the user, instead of the hint text.ĬontentDescription on an EditText control is only read before text is typed into the field, once the field is emptied the contentDescription is no longer read. Note: For EditText fields, provide an android:hint attribute instead of a content description, to help users understand what content is expected when the text field is empty. Associate an android:hint attribute with any graphical icons used by controls that provide feedback to the user (for example, status or state information).Provide an android:hint attribute instead of a content description for EditText fields.

Use the android:contentDescription attribute to label the ImageButton, ImageView, CheckBox and other user interface controls.
