android addTextChangedListener(TextWatcher) not working for the second time -

i have 6 edit texts on screen (used enter 6 digits) if enter 1 digit on 1 edittext field focus should go onto next 1 , on. if hit space on edit text field focus should come previous edittext field

for used below code

 edittext2.addtextchangedlistener(new textwatcher() {          public void ontextchanged(charsequence s, int start, int before, int count) {              if (edittext2.gettext().tostring().length() == 1) {                 edittext3.requestfocus();             }             else if (edittext2.gettext().tostring().length() == 0) {                 edittext1.requestfocus();             }         }          public void beforetextchanged(charsequence s, int start, int count, int after) {          }          public void aftertextchanged(editable s) {          }     }); 

normally , ontextchange listener works if don't hit backspace on of edit texts. if hit backspace on edittext2 , land on edittext1(some value on present) , try enter on it. cursor not going edittext2 addtextchangedlistener not working.

any appreciated.

i'm assuming you've set edittext fields maxlength of 1. this:

<edittext     android:id="@+id/edit_text_one"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:maxlength="1"     android:inputtype="number"     android:digits="0123456789"     /> 

when maxlength set 1, textwatcher not triggered when trying enter additional characters. 1 way solve problem when moving backwards use edittext.setselection(0, edittext.length()); see below working example:

final list<edittext> fields = new arraylist<>();  fields.add((edittext) findviewbyid(r.id.edit_text_one)); fields.add((edittext) findviewbyid(r.id.edit_text_two)); fields.add((edittext) findviewbyid(r.id.edit_text_three)); fields.add((edittext) findviewbyid(r.id.edit_text_four)); fields.add((edittext) findviewbyid(r.id.edit_text_five)); fields.add((edittext) findviewbyid(r.id.edit_text_six));  (edittext edittext : fields) {   edittext.addtextchangedlistener(new textwatcher() {     @override     public void beforetextchanged(charsequence charsequence, int start, int count, int after) {}      @override     public void ontextchanged(charsequence charsequence, int start, int count, int after) {       (int = 0; < fields.size(); i++) {         // determine 1 of fields focused         if (fields.get(i).hasfocus()) {           if (charsequence.length() == 1) {             // if focused field has character in it, move next field             if (fields.size() > + 1) {               edittext nextfield = fields.get(i + 1);               nextfield.requestfocus();             }           } else if (charsequence.length() == 0) {             // if focused field deleted, move previous field             if (i - 1 >= 0) {               edittext prevfield = fields.get(i - 1);               prevfield.requestfocus();               // select text replaced when pressing button               prevfield.setselection(0, prevfield.gettext().length());             }           }           break;         }       }     }      @override public void aftertextchanged(editable editable) {}   }); }
