java - Spinner not a view that can be bounds(sp) by this SimpleCursorAdapter -


i'm trying adapt query spinner object trouble, error listed title. here code portion crashes:

        spinner classdropdown = (spinner) this.findviewbyid(r.id.classdropdown);         int[] = new int[] { r.id.classdropdown };         string[] classfields = new string[] { "classname" };         simplecursoradapter cursoradapter = new simplecursoradapter(this, r.layout.main, cursor, classfields, to);         cursoradapter.setdropdownviewresource(r.id.classdropdown);         classdropdown.setadapter(cursoradapter);

i had problem cursor wasn't being filled fixed now. can give me on debugging issue?

edit: think problem "to" field. should be?

edit 2: also, here xml spinner object:

<spinner         android:id="@+id/classdropdown"         android:layout_width="match_parent"         android:layout_height="wrap_content" />

edit 3: i've fixed above reflect fixing code. fixes particular problem. i'm not getting error, have nothing displayed in spinner.

to list of resource ids want put data into, such r.id.textview1, , meed contained in layout specify in adapter. number of elements should match number of elements in array ( called classfields).

so, have 2 pieces of data , specified 1 target resource id. either remove 1 of fields in classfields array or add widget layout , call.it in array , should work.
