Answer 2

     List<String> mStrings = new ArrayList<String>();

        Editable s = editText.getText();

            char c;
            for(int i=0; i< editText.length(); i++){

                char result = s.charAt(i);
                 textView.append(String.valueOf(result));
               mStrings.add(String.valueOf(result));

                try{

                    Thread.sleep(10);
                    editText.setText(mStrings.get(1));
                }catch(Exception e){}

    }
