In android, when "Talk back" is enabled and it reads text from a Overflow Scrollable TextView, it keeps on reading the entire text without scrolling. So it also reads the text that is not visible on screen. Is there a way by which we can make the TextView to auto scroll along with the text that "Talk back" is reading.
No. The body of this answer must be 30 characters.
Seriously though, there is no way to do this. This is a platform limitation. You could consider chunking your text into multiple views. This is generally more accessible as large blocks of text take a long time for TalkBack to read and can be frustrating for users.
