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 ArrayAdapter<String> {
private ArrayList<String> items;
public ScoringAdapter(Context context, int textViewResourceId,
ArrayList<String> 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;
}
}
