android - I can't setId to a dynamic a Spinner? -


i can't setid dynamic spinner!?

what trying add 1 spinner every tablerow, depending on amount of rows in database (i not trying show database). spinner's id needs set based on number in database.

final string marray[] = { "1", "2", "3" };  do{     int db_number = c.getint(getcolumnindex("number"));     int db_type = c.getint(getcolumnindex("type"));  spinner sp_type = new spinner(this); sp_type.setid(db_number + 10000); arrayadapter<string> adapter = newarrayadapter<string(this,android.r.layout.simple_spinner_item,                                     marray); sp_type.setadapter(adapter); if (db_type == 1) {     sp_type.setselection(0); } else if (db_type == 2) {     sp_type.setselection(1); } else {     sp_type.setselection(2); } tr.addview(sp_type); }while(c.movetonext());

this crashes app. however, if remove line "sp_type.setid(db_number + 10000);" not error.

here's logcat:
