android - Row color based on contents in the ListView of my RSS reader -

-

i android newbie , have built simple rss reader application based around free ibm android rss tutorial. change background color of each row if category of row equal particular string.

i wrote following "for loop" discovers category of each item , runs if statement should category equal "news". @ moment background colour of entire listview gets changed feed supplied news category.

does out there feel helping out beginner?

for(int = 0; < feed.getitemcount(); i++) {     if (feed.getitem(i).getcategory().equals("news"))     {        listview.setbackgroundcolor(0x77ee0044);     } }

you're going need inside getview() method of adapter.

before return view in getview(), can call setbackgroundcolor() on view or use 1 of other setbackgroundfoo() methods.

edit - given code, when create adapter, try:

arrayadapter<rssitem> adapter = new arrayadapter<rssitem>(   this,android.r.layout.simple_list_item_1,feed.getallitems(­)) {     @override     public view getview(int position, view convertview, viewgroup parent) {         view view = super.getview(position, convertview, parent);         if (getitem(position).getcategory().equals("news")) {             view.setbackgroundcolor(0xffff0000); // red         }         return view;     } };

this overrides getview() adjust background of list item views properly.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
