android - custom filter in custom arrayadaper by icon -
i have custom arrayadapter:
public class calladapter extends arrayadapter<callitem> implements filterable{ view view; contactholder holder = null; int color = 0; context context; int layoutresourceid; public static int rowheight = 0; private viewswitcher switcher; list<callitem> contacts = null; map<contactitem, view> contactviewmap = contactsviewmapsingletone.getinstance().getorderviewmap(); private arraylist<callitem> filtredcontacts; private filter filter; public calladapter(context context, int layoutresourceid,list<callitem> contacts) { super(context, layoutresourceid, contacts); this.layoutresourceid = layoutresourceid; this.context = context; this.contacts = contacts; this.filtredcontacts = new arraylist<callitem>(); this.filtredcontacts.addall(contacts); } @override public callitem getitem(int arg0) { return contacts.get(arg0); } @override public long getitemid(int arg0) { return arg0; } /** * метод для привязки элементов ui к данным конкретного контакта */ @override public view getview(int position, view convertview, viewgroup parent) { view row = convertview; view = row; if(row == null) { layoutinflater inflater = (layoutinflater)this.context.getsystemservice(context.layout_inflater_service); row = inflater.inflate(r.layout.call_item, parent, false); holder = new contactholder(); holder.contacticon = (imageview)row.findviewbyid(r.id.contacticon); holder.contactname = (customtextview)row.findviewbyid(r.id.contactname); holder.contactnumber = (customtextview)row.findviewbyid(r.id.contactnumber); holder.contactdays = (customtextview)row.findviewbyid(r.id.contactdays); row.settag(holder); } else { holder = (contactholder)row.gettag(); } callitem contact = contacts.get(position); try { holder.contacticon.setbackgroundresource(contact.geticon()); holder.contactname.settext(contact.getname()); holder.contactnumber.settext(contact.getdays()); } catch(exception e) { e.printstacktrace(); } return row; } @override public filter getfilter() { if (filter == null) filter = new callfilter(); return filter; } static class contactholder { imageview contacticon; customtextview contactname; customtextview contactnumber; customtextview contactdays; } @suppresslint("defaultlocale") private class callfilter extends filter { @override protected filterresults performfiltering(charsequence constraint) { log.i(" filtered value", constraint.tostring()); filterresults results = new filterresults(); string prefix = constraint.tostring().tolowercase(); if (prefix == null || prefix.length() == 0) { results.values = contacts; results.count = contacts.size(); } else { final arraylist<callitem> list = new arraylist<callitem>(); synchronized (this) { list.addall(contacts); } filtredcontacts.clear(); int count = list.size(); (int i=0; i<count; i++) { final callitem pkmn = list.get(i); if(pkmn.getname().tolowercase(locale.getdefault()).contains(constraint)) { log.i("found pref",pkmn.tostring() ); filtredcontacts.add(pkmn); } } log.i("prefix",prefix); for(int = 0, l = filtredcontacts.size(); < l; i++) { log.i("filtered list",filtredcontacts.get(i).tostring()); } results.values = filtredcontacts; results.count = filtredcontacts.size(); } return results; } @suppresswarnings("unchecked") @override protected void publishresults(charsequence constraint, filterresults results) { filtredcontacts = (arraylist<callitem>)results.values; notifydatasetchanged(); clear(); for(int = 0, l = filtredcontacts.size(); < l; i++) { add(filtredcontacts.get(i)); } notifydatasetchanged(); } } } but need filter items not name, icon. user chooses icon items should filtered , see list of items those, have icon on top. tried implement (pass int parameter) in performfiltering have charsequence parameter. , need implement feature not on typing value in edittext usual, icon int in activity , return list , see items filtered. sorry english.
i solved not using custom filter, implementing not elegant, workable solution. when return fragment int value adapter should filtered, this:
public void onactivityresult(int requestcode, int resultcode, intent data) { if (requestcode==1) { if(resultcode == 0) { adapter.clear(); arraylist<callitem> filtered = new arraylist<callitem>(); int a=0; (callitem call : adapter.getitems()) { if (call.geticon() == r.drawable.incoming_call) { log.i("item filter", call.tostring()); adapter.insert(call, a); a++; } else { filtered.add(call); } } adapter.addall(filtered); adapter.notifydatasetchanged(); } else if (resultcode==1) { adapter.clear(); arraylist<callitem> filtered = new arraylist<callitem>(); int a=0; (callitem call : adapter.getitems()) { if (call.geticon() == r.drawable.outgoing_call) { log.i("item filter", call.tostring()); adapter.insert(call, a); a++; } else { filtered.add(call); } } adapter.addall(filtered); adapter.notifydatasetchanged(); } else if(resultcode==2) { adapter = new calladapter(getactivity(), r.layout.call_item, faq.getdisplaycalls(getactivity())); contancts_list.setadapter(adapter); } } } as mentioned, maybe not elegant, workable me. hope useful somebody.
