java - When I set a content descriptor on a button subclass in Android, the word "button" gets appended on TalkBack -

i trying talkback read content descriptor on button subclass. 1 time button subclass selected, talkback gives me content descriptor plus word "button" @ end. how prevent word beingness appended?

note: did doc reading , noticed dispathpopulateaccessibilityevent() mentions getting accessibilityevent populated/visiting children of view acted event trigger. mean event touches view hierarchy?, , if so, button superclass adding text?

a simple workaround avoid using button, causes words added.

for example, may able replace textview, made button, , add together click listener using view.setonclicklistener(listener) desired effect - see android docs.

there number of such listeners in basic view class can added ui component using view.seton<event>listener(listener) in activity.oncreate method. in case, double-tap listener constructed ontouchlistener, though may require little experimentation precise result want.
