public class eventfragment extends listfragment { //set database allow user retrieve data populate eventfragment.java private appointmentcontroller appointmentdatabase; //list appointments private list<appointment> allappointment; eventadapter adapter; appointment selected_appointment; @override public void onactivitycreated(bundle savedinstancestate) { super.oncreate(savedinstancestate); //get appointment appointmentdatabase = new appointmentcontroller(getactivity()); appointmentdatabase.open(); allappointment = appointmentdatabase.getallappointment(); //initialise arrayadapter adapter view adapter = new eventadapter(getactivity(), r.layout.row_event, allappointment); setlistadapter(adapter); getlistview().setonitemlongclicklistener(new adapterview.onitemlongclicklistener() { @override public boolean onitemlongclick(adapterview<?> arg0, view view, int position, long id) { // remove code simplicity } @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { view rootview = inflater.inflate(r.layout.fragment_listfragment, container, false); return rootview; } @override public void onlistitemclick(listview l, view v, int position, long id) { super.onlistitemclick(l, v, position, id); // remove code simplicity }
if wants make onitemclick work add
android:descendantfocusability="blocksdescendants"
to parent layout it:-
<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/caldroid_transparent" android:orientation="vertical" android:descendantfocusability="blocksdescendants"> </linearlayout> when blocksdescendants can not onclick event on button in row of listview. can event on either row or button in row.
