Question

I have a spinner widget and I want to populate some data when user clicks on one of the items from spinner. So I have the position number like 0,1,2,3… for spinner items.

Now I have a table which have three fields as

  _id    cid    relatedname

   1       1          A
   2       1          B
   3       2          C
   4       2          D
   5       2          E

I want when a user clicks position 1 from spinner then it will check for cid and all the relatedname will be displayed whose cid is 1.

How to do this ?

Answer 1

setOnItemChangelistener() to spinner then do as follows in tat listener.

loadRelatedName(position + 1);    

void loadRelatedName(int cid) 
{
     sql = " SELECT * FROM table WHERE cid = " + cid;
     Cursor c = db.select(sql);
     if (c ! null)
        while(c.moveToNext()) {
            Syso("Related Name : " + c.getString[2]);
     }
}
