This works for me;
private Cursor c;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
Integer category = this.getIntent().getIntExtra("category", -1);
mediator = new SqliteMediator(this);
c = mediator.getFitlerNames(category);
ListAdapter adapter =
new SimpleCursorAdapter(this,
R.layout.row,
c,
new String[] {column},
new int[] {R.id.name});
setListAdapter(adapter);
}
public void onListItemClick(ListView parent, View v, int position, long
id) {
c.moveToPosition(position);
int filterId = c.getInt(0);
c.close();
mediator.onStop();
setResult(RESULT_OK, new Intent().putExtra("_id", filterId));
finish();
}
