StructNote Artikel speichern jede Listenansicht

StructNote:

public class StructNote { 
    public int  id; 
    public String singer; 
    public String title; 
} 

AdapterNote Set in Listenansicht foreach Kind von Listview

AdapterNote:

public class AdapterNote extends ArrayAdapter<StructNote> { 

    public AdapterNote(ArrayList<StructNote> array) { 
     super(G.context, R.layout.post, array); 
    } 

    private static class ViewHolder { 
     ... 
}

Try this:

final ArrayList<StructNote> notesPage = new ArrayList<StructNote>(); 
final ListView lstContent = (ListView) findViewById(R.id.lstContent); 
adapter = new AdapterNote(notesPage); 
LayoutInflater inflater = getLayoutInflater(); 
View addNew = inflater.inflate(R.layout.addnew, lstContent, false); 
lstContent.addHeaderView(addNew, null, false); 
lstContent.setAdapter(adapter); 
adapter.notifyDataSetChanged();
