How to disable a button?

Question

Android

Hello, I've run into this problem.

I have three buttons, on each I have a dawn and up touch handler, after releasing my finger from the button, the thread falls asleep to me, then the function that updates them should start. At this time, if you press the button and release it again, the thread falls asleep again, that is, an endless dream of the thread is obtained.

switch (view.getId()) {
                case R.id.answer1:
                    if (motionEvent.getAction() == MotionEvent.ACTION_DOWN) {
                        int trueNum = 0;
                        for (int i = 0; i < 15; i++) {
                            if (text1.equals(questions.getTrueList(i))) {
                                answer1.setBackgroundDrawable(getDrawable(R.drawable.button_levels_true));
                                trueNum = 1;
                            }
                        }
                        if (trueNum == 0) answer1.setBackgroundDrawable(getDrawable(R.drawable.button_levels_false));
                    }
                    if (motionEvent.getAction() == MotionEvent.ACTION_UP) {
                        try {
                            Thread.sleep(600);
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                        changeQuestion();
                    }
                    break;

I need to find a method where you can disable the properties of a button or disable its up handler. How much I googled, I found only setEnabled (false) and that's it.
I'm new to this stuff, by the way.)

Answer 1

Thread.sleep(600); - on the UI thread is not allowed.
take as a basis the single click example

And it's better to do it through timerTask
