Well,
I have this in my main class:
// Build the listview
MyAdapter<String> adapter = new
MyAdapter<String>(this,android.R.layout.simple_list_item_1, values);
// ArrayAdapter<String> adapter = new
ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,
values);
theList.setAdapter(adapter);
theList.setOnItemClickListener(new MyOnItemClickListener(this));
// Set the color based upon the string value
View rowView;
int listCount;
View fooView;
c.moveToFirst();
listCount = adapter.getCount();
for (int i=0;i<numRows;i++) {
rowView = adapter.getView(i, null, theList);
((TextView)rowView).setTextColor(0x64788e);
/*
if (rowView != null) {
if (c.getString(1).equals("foo")) {
((TextView)rowView).setTextColor(0x64788e);
} else {
((TextView)rowView).setTextColor(0x7b2325);
}
}
*/
c.moveToNext();
}
And in my derived adapter, I have this:
public class MyAdapter<T> extends ArrayAdapter<T> {
public MyAdapter(Context context, int textViewResourceId, T[] objects) {
super(context, textViewResourceId, objects);
}
// context, int, <T>[]
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
TextView rowView;
rowView = (TextView) super.getView(position, convertView, parent);
((TextView)rowView).setTextColor(0x64788e);
return super.getView(position, convertView, parent);
}
The result from hacking around is that the list has invisible values.
I guess its time to look at your pdf. lol
