     String values;
       if (cursor.moveToFirst()) {
                do {

               values=values + cursor.getString(0)+",";

                } while (cursor.moveToNext());

remove last comma

if (values.length() > 0)
 {
    values= values.substring(0,values.length() - 1);    
  }

Here is my code i used...hope it helps you.

 private SQLiteDatabase myDataBase;
 Cursor cursor;
 String S="";
 String myPath2 = yourDBpath + yourDBNAME;
 try{
 myDataBase = SQLiteDatabase.openDatabase(myPath2, null,SQLiteDatabase.OPEN_READWRITE);
 String sql="your query";
 cursor=myDataBase.rawQuery(sql, null);
if(cursor != null)
{
   while(cursor.moveToNext())
   {
    S=S.append(cursor.getString(0));
    }
}
  } 
}catch(Exception e){

        }finally{
        myDataBase.close();
        }

Final result will be there in String S.

In SQLite, you can use GROUP_CONCAT():

select Group_Concat(EmployeeName)
from table1

See SQL Fiddle with Demo

If you had multiple fields that you want to return, then you would use a GROUP BY with the query, similar to this:

select id, Group_Concat(EmployeeName)
from table1
group by id

See SQL Fiddle with Demo
