pullToRefresh Libreria problema adapter
Hola comapñeros acabo de empezar a usar la libreria PullToRefresh para implementarla en una listaexpandible de rss que lleva mi proyecto , por lo que veo en los ejemplos se usa simpleexpandablelistadapter pero esto no me permite editar los items como yo quiero y uso un baseexpandablelistadapter en mi adapter, mi duda es que Los pulltorefresExpandableListView solo permiten ListAdapter y no el que yo uso , me da error en ListView.setadapter() porque no es un listadapter , como podría solucionar esto?
Mi java:
Código:
public class Rss extends SherlockActivity {
private String rssURL="http://www.amsspecialist.com/feed.php?";
private PullToRefreshExpandableListView Listview;
//private ExpandableListView ListView;
private RssAdapter adp;
private SharedPreferences Settings;
private Intent in;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_rss);
Settings = PreferenceManager.getDefaultSharedPreferences(this);
Listview=(PullToRefreshExpandableListView )findViewById(R.id.expandableListView1);
Listview.setShowIndicator(false);
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
loadRss rss=new loadRss(this);
rss.execute(rssURL);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.rss, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
switch(item.getItemId()) {
case R.id.config_rss:
startActivity(new Intent(getBaseContext(),
PreferenciasActivity.class));
break;
}
return true;
}
private class loadRss extends AsyncTask<String,Void,String> {
private ProgressDialog pDialog;
private Context context;
private ArrayList<rssItem> ListGroup;
private ArrayList<ArrayList<String>> ListChilds;
public loadRss(Context con){
this.context=con;
pDialog = new ProgressDialog(con);
}
@Override
protected void onPreExecute() {
pDialog.setMessage(getString(R.string.cargando));
pDialog.setCancelable(true);
pDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
pDialog.show();
}
@Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
StringBuffer buf = new StringBuffer("");
try {
// Read all the text returned by the server
URL xmlUrl = new URL(params[0]);

xmlUrl.openStream(), "UTF-8");

String str;
while ((str = in.readLine()) != null) {
buf.append(str + "\r\t");
}
in.close();
} catch (IOException e) {
e.printStackTrace();
}
return buf.toString();
