   // handle click on list view item             listviewphonebook.setonitemclicklistener(new adapterview.onitemclicklistener() {                 public void onitemclick(adapterview<?> arg0, view v,int position, long arg3)                 {                     // position parameter gives index or position of listview item clicked                     textview tv=(textview)v.findviewbyid(r.id.textviewname);                     string name=tv.gettext().tostring();                     toast.maketext(getapplicationcontext(), "contact selected: " + position, toast.length_long).show();                      cursor c = (cursor) arg0.getitematposition(position);                    // cursor c = (cursor)arg0.getadapter().getitem(position);                     string number = c.getstring(c.getcolumnindex(contactscontract.commondatakinds.phone.number));                     toast.maketext(getapplicationcontext(), "contact selected: " + number, toast.length_long).show();                   }             }); 

error:- java.lang.illegalstateexception: couldn't read row 0, col -1 cursorwindow. make sure cursor initialized correctly before accessing data it. @ android.database.cursorwindow.nativegetstring(native method)

you can read of telephone numbers associated contact in following manner:

uri personuri = contenturis.withappendedid(people.content_uri, personid); uri phonesuri = uri.withappendedpath(personuri, people.phones.content_directory); string[] proj = new string[] {phones._id, phones.type, phones.number, phones.label} cursor cursor = contentresolver.query(phonesuri, proj, null, null, null);
