change this:
i.putextra("partyname", (parcelable) partynametext); i.putextra("promoternametext", (android.os.parcelable) promoternametext); i.putextra("costtext", (android.os.parcelable) costtext) to this:
i.putextra("partyname", partynametext.gettext().tostring()); i.putextra("promoternametext", promoternametext.gettext().tostring())); i.putextra("costtext", costtext.gettext().tostring())) this adds data intent 'i' strings. can't cast textview parcelable.
