Question

我对ProgressBar有问题，因为它没有正确显示它。

代码：

 private void setTimer() {

    if(np3.getValue() == 0){
        time_one = (np1.getValue()) + (np2.getValue() * 60);
        totalTimeCountInMilliseconds = time_one * 1000;
    } else {
        time_two = (np1.getValue()) + (np2.getValue() * 60) + ((np3.getValue() * 3600)-3600);
        totalTimeCountInMilliseconds = time_two * 1000;
    }
    np1.setVisibility(View.GONE);
    np2.setVisibility(View.GONE);
    np3.setVisibility(View.GONE);
    textViewShowTime.setVisibility(View.VISIBLE);

    timeseconds = 10 * 1000;
}

private void startTimer() {
    countDownTimer = new CountDownTimer(totalTimeCountInMilliseconds, 500) {
        @Override
        public void onTick(long leftTimeInMilliseconds) {

                if (leftTimeInMilliseconds <= timeseconds) {
                    if(change == false){
                        textViewShowTime.setVisibility(View.VISIBLE);
                        textViewShowTime.setTextSize(20);
                        textViewShowTime.setTextAppearance(getApplicationContext(),
                                R.style.RedText);
                        change = true;
                    } else{
                        textViewShowTime.setVisibility(View.GONE);
                        change = false;
                    }
                }

            if(np3.getValue() == 0){
                Date date = new Date(leftTimeInMilliseconds);
                DateFormat formatter = new SimpleDateFormat("mm:ss");
                String dateFormatted = formatter.format(date);
                textViewShowTime.setText(String.format(dateFormatted));
                textViewShowTime.setTextSize(40);
                pb.setVisibility(View.VISIBLE);

                if(progressStatus <100){
                    int end_time = 100 / time_one;
                    progressStatus += end_time;
                    pb.setProgress(progressStatus);
                }

这是问题所在。

new CountDownTimer(totalTimeCountInMilliseconds, 500)

如果您想模拟1秒，为什么在500 上打勾。应该 1000 。

由于此问题，您的ProgressBar填写速度很快。将其更改为

new CountDownTimer(totalTimeCountInMilliseconds, 1000)

更新此内容。我认为你不需要change布尔

textViewShowTime.setVisibility(View.VISIBLE);
textViewShowTime.setTextSize(20);
textViewShowTime.setTextAppearance(getApplicationContext(),R.style.RedText);

进度条无法正确显示
