Question

I am using onTextChanged(charSequence s, int start, int before, int count) and would like to get the deleted text of an Edittext. I believe you can get it through the parameter s but how would I know that the text has been deleted not added? (E.g. if s.equals("Example") how do I know that “Example” was deleted from, not added to, the Edittext?)

Answer 1

If you’re deleting text from an EditText, the final parameter for onTextChanged, int lengthAfter should be equal to zero (you have this parameter labeled ‘count’).

onTextChanged (CharSequence text, int start, int lengthBefore, int lengthAfter)

You could also consider using a TextWatcher for finer control.
