Hi All,
Struggling and struggling, but can't find the thing i'm doin wrong in my
listview implementation. No exceptions, just no listview. I have a
customized adapter with an overridden getView method, but the Log.d won't
show, so i guess my adapter is just wrong? Could somebody have a look at the
code below? Thanks in advance!

public class ArticleList extends ListActivity {
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
// call super constructor
super.onCreate(savedInstanceState);
// set the layout used for this activity
setContentView(R.layout.article_list);
// create a new splashscreen and show it:
SplashScreen ss = new SplashScreen(this);
ss.show();
// now that we have the splash screen displayed fire up the
// method that's going to fetch our content
ArticleListView alv = new ArticleListView(this);
alv.setSource("rss");
alv.show();
ss.hide();
}
public class ArticleListView {
private String source=null;
private ListView lv;
public ArticleListView(ListActivity act) {
// find the list view
lv = (ListView) act.findViewById(android.R.id.list);
// get the messages
FeedManager fm = new FeedManager();
Feed f = fm.getFeed("Some valid feed url");
List<FeedMessage> messages = f.getMessages();
// get the adapter for the list
ArticleDetailAdapter adp = new ArticleDetailAdapter(act,
android.R.layout.simple_list_item_2, messages);
lv.setAdapter(adp);
}
public void show(){
lv.setVisibility(View.VISIBLE);
}
public void hide(){
lv.setVisibility(View.GONE);
}
public void setSource(String source){
this.source = source;
}
public String getSource(){
return source;
}
