Android app fails due to a java.lang.StackOverflowError -

-

i'm making android program , it's failing due stackoverflow error. have attached code. i'm using android studio. believe it's looping because of addtextchangedlistener can't understand why it's doing it.

my code:

    rb1 = (radiobutton) findviewbyid(r.id.radiobuttoncfm);     rb2 = (radiobutton) findviewbyid(r.id.radiobuttonac);      rb1.setonclicklistener(new radiogroup.onclicklistener() {          public void onclick(view v) {              edittext e1 = (edittext) findviewbyid(r.id.edittext);              string susername1 = e1.gettext().tostring();              if (textutils.isempty(susername1)) {                  e1.seterror("the item cannot empty.");                  return;              }               edittext e2 = (edittext) findviewbyid(r.id.edittext2);              string susername2 = e2.gettext().tostring();              if (textutils.isempty(susername2)) {                  e2.seterror("the item cannot empty.");                  return;              }               edittext e3 = (edittext) findviewbyid(r.id.edittext3);              string susername3 = e3.gettext().tostring();              if (textutils.isempty(susername3)) {                  e3.seterror("the item cannot empty.");                  return;              }               e1.addtextchangedlistener(new textwatcher() {                   public void aftertextchanged(editable s) {                  }                   public void beforetextchanged(charsequence s, int start,                                                int count, int after) {                  }                   public void ontextchanged(charsequence s, int start,                                            int before, int count) {                      edittext e1 = (edittext)findviewbyid(r.id.edittext);

                 }              });           }      });      }

your textwatcher that's watching input of r.id.edittext3 modifying text of r.id.edittext2, in turn modifying r.id.edittext3. through that, you'll infinite calls ontextchanged(...).
