I am making a chess clock but in it I need a delay (Like it waits 10 seconds before counting). I used a Handler for it but if the button is clicked in the 10 seconds, nothing happens. Please help! Thanks! My code:
mHandler.postDelayed(new Runnable() {
public void run() {
// count down timer start
timer2 = new CountDownTimer(totalSeconds, Integer.parseInt(delay.getText().toString())) {
public void onTick(long millisUntilFinished) {
secondsTimer = (int) (millisUntilFinished / 1000) % 60;
minutesTimer = (int) ((millisUntilFinished / (1000 * 60)) % 60);
hoursTimer = (int) ((millisUntilFinished / (1000 * 60 * 60)) % 24);
person2.setText(hoursTimer + ":" + minutesTimer + ":" + secondsTimer);
}
public void onFinish() {
person2.setText("Time Up!");
person2.setBackgroundColor(Color.RED);
mp.start();
}
}.start();
}
}, finalDelay);
I want a delay but I don't want to lock the UI and make the app unresponsive as it is doing right now with the handler. Any help will be appreciated! Thanks in advance!

You can avoid using Handler
starting timer immediately
private fun start10SecondsDelayTimer() {
var delayCount = 10
val timer = object : CountDownTimer(1_000_000L, 1000L) {
override fun onTick(millisUntilFinished: Long) {
if (delayCount > 0) {
delayCount--
} else {
//your calculations
}
}
override fun onFinish() {
//some calculations
}
}
timer.start()
}
but first ticks will be without your calculations

I think you shouldn't put CountdownTimer into Handler. You could create 2 handler instead. Here is an example.
private void startHandlerAndWait10Seconds(){
Handler handler1 = new Handler();
handler1.postDelayed(new Runnable() {
public void run() {
// Start Countdown timer after wait for 10 seconds
startCountDown();
}
}, 10000);
}
private void startCountDown {
final Handler handler2 = new Handler();
handler2.post(new Runnable() {
int seconds = 60;
public void run() {
seconds--;
mhello.setText("" + seconds);
if (seconds < 0) {
// DO SOMETHING WHEN TIMES UP
stopTimer = true;
}
if(stopTimer == false) {
handler2.postDelayed(this, 1000);
}
}
});
}

If you want to start the timer immediately,
findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
new Handler().post(new Runnable() {
public void run() {
// count down timer start
new CountDownTimer(100000, 1000) {
public void onTick(long millisUntilFinished) {
button.setText(String.valueOf(millisUntilFinished));
}
public void onFinish() {
button.setText("Time Up!");
}
}.start();
}
});
}
});
And if you want to execute it after a certain time period, then
findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
new Handler().postDelayed(new Runnable() {
public void run() {
// count down timer start
new CountDownTimer(100000, 1000) {
public void onTick(long millisUntilFinished) {
button.setText(String.valueOf(millisUntilFinished));
}
public void onFinish() {
button.setText("Time Up!");
}
}.start();
}
}, 1000);
}
});
