Remarks

Adds a TextWatcher to the list of those whose methods are called whenever this TextView's text changes.

In 1.0, the TextWatcher#afterTextChanged method was erroneously not called after #setText calls. Now, doing #setText if there are any text changed listeners forces the buffer type to Editable if it would not otherwise be and does call this method.
