Different numbers on buttons

I am a beginner programmer on Android and I create my own game that adds from randomly generated numbers. the player's task is to guess the result by adding, by selecting 3 given numbers in which is the real result. Everything works fine but I would like the correct result every round was on another button so that the player does not realise that the correct result is on button number 1 and buttons 2 and 3 are false

private void startTimerThread() {
        final Handler handler = new Handler();
        los();
        proba.setText("dodawanie");
        c = Dodawanie(a, b);
        Random liczba = new Random();
        h = liczba.nextInt(5);
        Toast.makeText(getApplicationContext(), String.valueOf(c), Toast.LENGTH_LONG).show();
        Runnable runnable = new Runnable() {
            public void run() {
                try {
                    Thread.sleep(100);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                handler.post(new Runnable() {
                    public void run() {
                        W1.setText(String.valueOf(c));
                        Wyb1.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                p++;
                                l.setText(String.valueOf(p));
                                startTimerThread();

                            }
                        });
                        W2.setText(String.valueOf(l1));
                        Wyb2.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                Toast.makeText(getApplicationContext(), "Zle", Toast.LENGTH_LONG).show();
                            }
                        });
                        W3.setText(String.valueOf(l2));
                        Wyb3.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                Toast.makeText(getApplicationContext(), "Zle", Toast.LENGTH_LONG).show();
                            }
                        });
                    }
                });

            }
        };
        new Thread(runnable).start();
    }

I tried to do it with the if and Class Random commands but sometimes did not give the correct result on the button

                   if(h==0||h==3) {
                                W1.setText(String.valueOf(c));
                                Wyb1.setOnClickListener(new View.OnClickListener() {
                                    @Override
                                    public void onClick(View v) {
                                        p++;
                                        l.setText(String.valueOf(p));
                                        Do();

                                    }
                                });
