java - calling getview() method in custom listview -



java - calling getview() method in custom listview -

i using custom listview text , arrow image @ right of list row.

i have following

1: mainactivity extends listactivity

2: specialadapter extends arrayadapter have getview() method.

3: classes sqlite dtabase.

i have edittext , add together button storing new text database list. code here .

onclicklistener listeneradd = new onclicklistener() { @override public void onclick(view v) { comment comment = null; edittext edit = (edittext) findviewbyid(r.id.edit_txt); string number = edit.gettext().tostring(); if(!number.equals("")){ comment = datasource.createcomment(number); adapter.add(comment); edit.settext(""); adapter.notifydatasetchanged(); } else{ toast.maketext(getapplicationcontext(), "please come in number",toast.length_short).show(); } } };

i totally confused in class should utilize code ???

how phone call getview method ??

i used code in main class throws exception.

the more of import adapter should use???

adapter code here..

public class specialadapter extends arrayadapter<comment>{ context context; int layoutresourceid; comment data[]= null; // comment datacom[] = null; public specialadapter(context context, int layoutresourceid,comment[] values) { super(context, layoutresourceid, values); this.layoutresourceid = layoutresourceid; this.context = context; this.data = values; } @override public view getview(int position, view convertview, viewgroup parent) { view row = convertview; weatherholder holder = null; if(row == null) { layoutinflater inflater = ((activity)context).getlayoutinflater(); row = inflater.inflate(layoutresourceid, parent, false); holder = new weatherholder(); holder.imgicon = (imageview)row.findviewbyid(r.id.img_arrow); holder.txttitle = (textview)row.findviewbyid(r.id.tv_number); row.settag(holder); } else { holder = (weatherholder)row.gettag(); } comment comment = data[position]; holder.txttitle.settext(comment.getcomment()); holder.imgicon.setimageresource(r.drawable.arrow); homecoming row; } static class weatherholder { imageview imgicon; textview txttitle; } }

you have set onclicklistner in yourclass extending actvity. create sure yourxml file contains button. otherwise exception.

i.e

setcontentview(r.layout.yourxmllayoutfilename);

your button should in yourxmllayoutfilename xml file

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
