The simple code is:
public class paraBorrar extends Activity {
/** Called when the activity is first created. */
private ArrayList<String> tit = new ArrayList<String>();
String horaIn;
String horaFi;
String canal;
int posicion;
int pos=0;
private ArrayList<String> des = new ArrayList<String>();
listaAdaptador adaptador3 = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ListView list=(ListView)findViewById(R.id.listaTele);
list.setFocusable(true);
list.setItemsCanFocus(true);
adaptador3 = new listaAdaptador();
list.setAdapter(adaptador3);
getRSS("http://www.miguiatv.com/rss/la2.xml","LADOS";);
}
private void getRSS(String rss,String tabla)
{
...................
}
class listaAdaptador extends ArrayAdapter<String> {
listaAdaptador() {
// super(paraBorrar.this, R.layout.row,R.id.programa,tit);
super(paraBorrar.this, R.layout.row,tit);
}
public View getView(int position, View convertView,
ViewGroup parent) {
View row = convertView;
ViewHolder holder;
Log.d("PRUEBA","la position con su respectivo valor es
..." +
tit.get(position));
if(row == null)
{
LayoutInflater inflater = getLayoutInflater();
row = inflater.inflate(R.layout.row, null);
holder = new ViewHolder();
holder.programa =
(TextView)row.findViewById(R.id.programa);
}
else {
holder = (ViewHolder)row.getTag();
}
holder.programa.setText(tit.get(position));
return(row);
}
}
static class ViewHolder {
public TextView programa;
}
