android - Strange ClassCastException with a Spinner -


i have code:

spinner entrega=(spinner)findviewbyid(r.id.comboentrega); //this line cracks     arrayadapter<charsequence> adapter = arrayadapter.createfromresource(this,             r.array.arrayentrega, android.r.layout.simple_spinner_item);     // specify layout use when list of choices appears     adapter.setdropdownviewresource(android.r.layout.simple_spinner_dropdown_item);     // apply adapter spinner     entrega.setadapter(adapter);

in layout:

<spinner     android:id="@+id/comboentrega"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_alignparentleft="true"     android:layout_below="@+id/textview4" />

when run app, receive stacktrace:
