Hi I am making simple countdown timer and I would like to resume it after pause. Very important for me is that I won't put my countdown timer to public void method.
mTextViewCountDown = findViewById(R.id.text_view_countdown);
mButtonStartPause = findViewById(R.id.button_start_pause);
mButtonStartPause.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (mTimerRunning) {
pauseTimer();
} else {
startTimer();
}
}
});
updateCountDownText();
mCountDownTimer = new CountDownTimer(mTimeLeftInMillis, 1000) {
@Override
public void onTick(long millisUntilFinished) {
mTimeLeftInMillis = millisUntilFinished;
updateCountDownText();
}
@Override
public void onFinish() {
mTimerRunning = false;
}
}.start();
}
private void startTimer() {
mTimerRunning = true;
mCountDownTimer.start();
}
private void pauseTimer() {
mCountDownTimer.cancel();
mTimerRunning = false;
mButtonStartPause.setText("Start");
}
private void updateCountDownText() {
int minutes = (int) (mTimeLeftInMillis / 1000) / 60;
int seconds = (int) (mTimeLeftInMillis / 1000) % 60;
String timeLeftFormatted = String.format(Locale.getDefault(), "%02d:%02d", minutes, seconds);
mTextViewCountDown.setText(timeLeftFormatted);
}
