How to restart postdelay handler if it is overloaded during delay countdown

Question

I have a problem that I cannot solve. I have a button that, when clicked, changes the text view. Then it activates the process postdelayed, which returns textviewto the source text after 2 seconds.

If I press the button once, and then again during this 2-second interval, it postdelaywill continue to count down from the first press and not restart from the second press. This causes the source text to appear when I want the text to be changed.

Each time the button is pressed, a delay is created from this instance. I want him to undo the previous one postdelayand launch a new one. This is my code so far, but it is not finished because I cannot figure out how to finish it (therefore it does not work).

p1AddL.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            counter1 ++;
            count1 ++;
            Handler h = new Handler();
            if ('PREVIOUS_DELAY_HAS_STARTED') {
                h.removeCallbacks(clickButton);
                h.postDelayed(clickButton, 2000);
            } else {
                h.postDelayed(clickButton, 2000);
            }
            if (count1 > 0) {
                lifepointsP1.setText("+" + count1);
                lifepointsP1.setTextColor(Color.argb(220, 0, 188, 0));
            }
        }
    });

Runnable clickButton = new Runnable() {
    @Override
    public void run() {
        count1 = 0;
        lifepointsP1.setTextColor(Color.WHITE);
        lifepointsP1.setText(counter1);
    }
};

the text PREVIOUS_DELAY_HAS_STARTEDshould be some kind of verification method, and I'm sure that I need something between the teams h.removeCallbacksand h.postDelayedin this text.

If this is an easier way / better way to write this method to make it work, please let me know. I have tried so many ways, and I feel that I am very close here.

Answer 1

removeCallbacks , clickButton h.

if ('PREVIOUS_DELAY_HAS_STARTED') {
    h.removeCallbacks(clickButton);
    h.postDelayed(clickButton, 2000);
} else {
    h.postDelayed(clickButton, 2000);
}

h.removeCallbacks(clickButton);
h.postDelayed(clickButton, 2000);
