Hi,
I am having some problems trying to extend the SimpleCursorAdapter,
the problem I am trying to solve is simple. I have the 'id' of an SMS
message and I want to associate this with the Name of the person who
sent it (if in the contact-book).
Basically I want to get the current cursor position , check if the
name exists and if so associate it with and @id tag in my layout.
The activity calls the extended cursor as follows:
===================================
String[] columns = new String[] { SMSConstants.ADDRESS,
SMSConstants.BODY};
int[] names = new int[] { R.id.subject, R.id.message };
Cursor c = getSMSCursor();
startManagingCursor(c);
SMSCursorAdaptor myAdapter = new SMSCursorAdaptor(this,
R.layout.table, c, columns, names);
setListAdapter(myAdapter);
The extended Cursor Class is defined as:
===================================
public class SMSCursorAdaptor extends SimpleCursorAdapter {
private Cursor c;
private Context context;
private int layout;
public SMSCursorAdaptor(Context context, int layout, Cursor c, String
[] from, int[] to) {
super(context, layout, c, from, to);
this.c = c;
this.context = context;
this.layout = layout;
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
/* Get the current Cursor */
Cursor cursor = getCursor();
/* Know the context */
ContentResolver cr = context.getContentResolver();
LayoutInflater inflate = LayoutInflater.from(context);
View v = inflate.inflate(layout, parent);
/* get the text view */
TextView textView = (TextView) v.findViewById(R.id.row_entry);
/* Now get the id number of the person */
int id = this.c.getColumnIndex("person");
/* Connection string to the DB */
Uri uri = ContentUris.withAppendedId(People.CONTENT_URI,
this.c.getLong(id));
/* Make the query */
Cursor person_cursor = cr.query(uri, null, null, null, null);
int idx = person_cursor.getColumnIndex(People.DISPLAY_NAME);
//String nameValue = person_cursor.getString(idx);
v.setId(idx);
return v;
}
}
Basically I am not sure how to set-up the textView so that it gets the
correct DISPLAY_NAME from the db and outputs it to the @id tag ...
No matter what I have tried I get an IndexOutOfBoundsException
