Android-the method Findviewbyid (int) is undefined for the type contactmainfragment error

    @Override    publicvoid  onviewcreated (view view, Bundle savedinstancestate) {         Super . onviewcreated (view, savedinstancestate);                 = (TextView) Findviewbyid (r.id.ivtitlename);        Mtitlenameview.setvisibility (view.visible);        Mtitlenameview.settext (r.string.company_name);

Hint: it should be a hint that the component ID could not be found

Workaround: Add view.

Mtitlenameview = (TextView) View.findviewbyid (r.id.ivtitlename);
