java - button action in fragment -

i have fragment , there textview , button, found solution adding action button inside fragment, must change text in textview. did in way, doesn't work, can check ?

fragment:

public class articlefragment extends fragment {   static public int licznik=0;   public view view;    @override     public view oncreateview(layoutinflater inflater, viewgroup container,                              bundle savedinstancestate) {         // inflate layout fragment        view = inflater.inflate(r.layout.article_view, container, false);       final textview article2 = (textview)view.findviewbyid(r.id.article);        button menubutton = (button)view.findviewbyid(r.id.button1);         menubutton.setonclicklistener(new view.onclicklistener() {             public void onclick(view v) {                 article2.settext(++licznik);             }         });          return view;     }    @override     public void onstart() {         super.onstart();          textview article = (textview)view.findviewbyid(r.id.article);         article.settext("cos tam");     } 

}

xml of fragment:

    <?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >      <textview         android:id="@+id/article"         android:layout_width="wrap_content"         android:layout_height="wrap_content"/>      <button         android:id="@+id/button1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="@string/reso"         android:onclick="action" />    </linearlayout> 

everything okey, during don't click button, application sttoped.

i'm guessing problem, eventhough have posted no log dump :

            article2.settext(++licznik); 

to

            article2.settext(string.valueof(++licznik)); 

otherwise looking resource.
