android - Cannot set spinner's selected item -

i want set selected item of spinner :

adapter = new arrayadapter<rue>(this, android.r.layout.simple_spinner_item, db.getallrues()); // db.getallrues() has data adapter.setdropdownviewresource(android.r.layout.simple_spinner_dropdown_item); rueppale.setadapter(adapter); rueppale.setselection(adapter.getposition(db.getrue(p.getdec_decoup_terri_code())), true); // p.getdec_decoup_terri_code() has data 

code of db.getrue :

public rue getrue(string decoup_terri_code) {     rue r = new rue();     string[] columns = {"decoup_terri_code","decoup_terri_nom"};     cursor c = bd.query(t_decoup_territ, columns, "decoup_terri_code=?", new string[]{decoup_terri_code}, null, null, null);     if (c != null && c.getcount() > 0 ) {         c.movetofirst();         r.setdecoup_terri_code(c.getstring(0));         r.setdecoup_terri_nom(c.getstring(1));     }     return r; } 

the problem @ runtime spinner not scroll automatically desired item ! bad in code ?

-- edit --

i overwrote equals method in class rue :

@override public boolean equals(object o) {     if (!(o instanceof rue)) {         return false;     }     rue comp = (rue) o;     return (this.getdecoup_terri_code() == comp.getdecoup_terri_code() && this.getdecoup_terri_nom() == comp.getdecoup_terri_nom()); } 

but spinner not select item !

ok , of @selvin implemented equals method posted in question. , replaced == comparator equals method.
