try this..i using code email , name contact. use code per requirement
@override protected void onactivityresult(int requestcode, int resultcode, intent data) { if (resultcode == result_ok) { if(requestcode==contact_picker_email) { cursor cursor = null; string email = ""; try { uri result = data.getdata(); log.v(debug_tag, "got contact result: " + result.tostring()); // contact id uri string id = result.getlastpathsegment(); // query email cursor = getcontentresolver().query(email.content_uri, null, email.contact_id + "=?", new string[] { id }, null); int emailidx = cursor.getcolumnindex(email.data); // let's first email if (cursor.movetofirst()) { email = cursor.getstring(emailidx); txtconfirmby.settext(email); } else { log.w(debug_tag, "no results"); } } catch (exception e) { log.e(debug_tag, "failed email data", e); } { if (cursor != null) { cursor.close(); } } } else if (requestcode==contact_picker_name) { uri contactdata = data.getdata(); cursor c = managedquery(contactdata, null, null, null, null); if (c.movetofirst()) { string name = c.getstring(c.getcolumnindexorthrow(people.display_name)); txtparticipant.settext(name); } } } } send request details this
