 I have an ArrayList connected to a ListView with an onclick event that

 When the list fits inside the screen (no scrolling) it works fine,
 however, when the list becomes long enought that I need to scroll I
 get the Force Close message.

 why is this?

Something I did not say - actually I forgot I even did it - is that I
subclasses ArrayAdapter.  Here is the subclass.




/*
 * Subclass of ArrayAdapter to change the color of the
 * text to red if it is not 100%
 *
 */
public class ScoringAdapter extends ArrayAdapterString {

private ArrayListString items;

public ScoringAdapter(Context context, int textViewResourceId,
ArrayListString items) {
super(context, textViewResourceId, items);
this.items = items;
}

@Override
public View getView(int position, View convertView, ViewGroup
parent) {
try {
View v = (ListView)convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate
(android.R.layout.simple_list_item_1, null);
}

String item = items.get(position);
TextView tv = (TextView) v.findViewById
(android.R.id.text1);
tv.setText(item);

if(!item.contains(100%)) {
tv.setTextColor(Color.RED);
}

return v;
}
catch(ClassCastException e) {
Log.e(TAG, convertView.toString()+ is not a valid
ListView!);
}

return null;
}
}

I think.

In your getView() method, don't cast it to ListView, remove that and I
guess, I will work.
