android - TextChange listener usage with single TextView -

i using addtextchangedlistener waits user input textview part of simple quiz app.

i using single activity of questions - updating ui whenever user proceeds next question. problem having listener picking events of questions due same textview being used. know methods of making listener listen events text view on current question?

//listener added in oncreate() textviewletter = (textview) findviewbyid(r.id.textview6); textviewletter.addtextchangedlistener(new textwatcher() {          @override         public void ontextchanged(charsequence s, int start, int before, int count) {          }          @override         public void beforetextchanged(charsequence s, int start, int count,                                       int after) {          }          @override         public void aftertextchanged(editable s) {              toast t = toast.maketext(introduction.this, "changed" toast.length_short);             t.show();         }     }); 

//methods ui updated - lessonno current question user on.

public void questionone(int lessonno)   {     resettext();     objective.settext(questions.get(lessonno).getobjective()); }  public void questiontwo(int lessonno) {     resettext();     objective.settext(questions.get(lessonno).getobjective()); } 

notice add listener textview, not setting it. if call addtextchangelistener more once, have multiple listeners triggred upon event.

when need load new question, update view rather recreate it. make sure initializing done in oncreate, including setting listeners views.

when user has next question, update textviews settext (and rest of views)
