Accessibility label on Android
An accessibility label helps users of assistive technologies to identify elements on the screen. The accessibility label is conveyed to assistive technologies. Accessibility labels are announced by the screen reader and presented visually by voice control.
On Android, you can use the contentDescription attribute to set an accessibility label.
You can also pass any kind of Span for greater control over pronunciation. For example, you can set a language by using LocaleSpan.
If another element is used to display the label, you can link the label by using the labelFor attribute.
// Set accessibility label
element.contentDescription = "Appt"
// Set accessibility label in Dutch language
val locale = Locale.forLanguageTag("nl-NL")
val localeSpan = LocaleSpan(locale)
val string = SpannableString("Appt")
string.setSpan(localeSpan, 0, string.length, Spanned.SPAN_INCLUSIVE_INCLUSIVE)
element.contentDescription = localeSpan
// Link visual label to field
textView.setLabelFor(R.id.editText)
