Hi,
In one of my projects I've got a ListView with some elements. But when
scrolling through this list I get the following error:

My adapter is:
class listaAdaptador extends ArrayAdapter<String> {
listaAdaptador() {
super(tele.this, R.layout.row,R.id.programa,tit);
}
public View getView(int position, View convertView,
ViewGroup parent) {
View row = convertView;
ViewHolder holder;
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));
ImageView icon=(ImageView)row.findViewById(R.id.icon);
if (tabhost.getCurrentTab() == 0){
Log.d("PRUEBA", "Cargamos el primer canal");
icon.setImageResource(R.drawable.la1);
}
if (tabhost.getCurrentTab() == 1){
Log.d("PRUEBA", "Cargamos el segundo canal");
icon.setImageResource(R.drawable.la2);
}
if (tabhost.getCurrentTab() == 2){
Log.d("PRUEBA", "Cargamos el primer canal");
icon.setImageResource(R.drawable.antena3);
}
if (tabhost.getCurrentTab() == 3){
Log.d("PRUEBA", "Cargamos el segundo canal");
icon.setImageResource(R.drawable.cuatro);
}
if (tabhost.getCurrentTab() == 4){
Log.d("PRUEBA", "Cargamos el primer canal");
icon.setImageResource(R.drawable.telecinco);
}
if (tabhost.getCurrentTab() == 5){
Log.d("PRUEBA", "Cargamos el segundo canal");
icon.setImageResource(R.drawable.sexta);
}
if (tabhost.getCurrentTab() == 6){
Log.d("PRUEBA", "Cargamos el primer canal");
icon.setImageResource(R.drawable.marca);
}
return(row);
}
}
