I have this database connector class with a constructor as follows
public class DBConnectionTableTVShow {
public DBConnectionTableTVShow(Context ctx){
this.context = ctx;
dbh = new DBHelper(context);
}
}
I can create object from an Activity like following
public class Select_episode extends Activity {
DBConnectionTableTVShow dbcon = new DBConnectionTableTVShow(this);
}
Now I want to create object, like i did in above in the custom view adapter class
public class CustomListViewAdapter extends BaseAdapter
{
}
How to do this?
I tried
DBConnectionTableTVShow dbcon = new DBConnectionTableTVShow(this);
this in CustomListViewAdapter
class and it doesn't work

If CustomListViewAdapter
is an inner class of Select_episode
then you can use
DBConnectionTableTVShow dbcon = new DBConnectionTableTVShow(Select_episode.this);
or you can create a constructor with a Context param and instantiate your database helper using the pass in context (when you pass this it is equivalent to passing a Context so instead of Activity you should make your param Context since you only need context)
LayoutInflater inflater;
List<ListViewItem> items;
DBConnectionTableTVShow dbcon;
public CustomListViewAdapter(Context context, List<ListViewItem> items) {
super();
this.items = items;
this.inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.dbcon = new DBConnectionTableTVShow(context);
}
