file : facebookadapter.java :
public class facebookadapter extends arrayadapter<rssfeedstructure> { list<rssfeedstructure> imageandtexts1 = null; public facebookadapter(activity activity, list<rssfeedstructure> imageandtexts) { super(activity, 0, imageandtexts); imageandtexts1 = imageandtexts; } @override public view getview(int position, view convertview, viewgroup parent) { activity activity = (activity) getcontext(); layoutinflater inflater = activity.getlayoutinflater(); view rowview = inflater.inflate(r.layout.facebookadapter, null); textview textview = (textview) rowview.findviewbyid(r.id.feed_text); textview timefeedtext = (textview) rowview .findviewbyid(r.id.feed_updatetime); imageview imageview = (imageview) rowview.findviewbyid(r.id.feed_image); try { log.d("rssfeed", "imageandtexts1.get(position).getimglink() :: " + imageandtexts1.get(position).getimglink() + " :: " + imageandtexts1.get(position).gettitle()); textview.settext(imageandtexts1.get(position).getdescription()); spannablestring content = new spannablestring(imageandtexts1.get( position).getpubdate()); content.setspan(new underlinespan(), 0, 13, 0); timefeedtext.settext(content); if (imageandtexts1.get(position).getimglink() != null) { url feedimage = new url(imageandtexts1.get(position) .getimglink().tostring()); if (!feedimage.tostring().equalsignorecase("null")) { httpurlconnection conn = (httpurlconnection) feedimage .openconnection(); inputstream = conn.getinputstream(); bitmap img = bitmapfactory.decodestream(is); imageview.setimagebitmap(img); } else { imageview.setbackgroundresource(r.drawable.rss_tab_tweets); } } } catch (malformedurlexception e) { } catch (ioexception e) { } return rowview; } } file : facebookactivity.java :
