Hello i am try to making application get data json from server, and i parse it and if variabel reksupx is equal t then, the checkbox is checked automatically. The json is alright, i have check it from System.out.println, but why checkbox can't checked? thanks in advance.

This is my code :

                                    check1.setChecked(true);
                                    check2.setChecked(false);
                                    check3.setChecked(false);
                        }
                        else if(reksup2=="t"){
                                    check1.setChecked(false);
                                    check2.setChecked(true);
                                    check3.setChecked(false);
                        }
                        else if(reksup3=="t"){
                                    check1.setChecked(false);
                                    check2.setChecked(false);
                                    check3.setChecked(true);
