Question

因此，放置div标题应该理论上放在div的顶部。这段代码是从我网站的另一个页面复制并粘贴的，我刚刚更改了div名称，因为其他一切都是相同的。但是，出于某种原因，我的div标题和div都显示在我的页面上，有没有人知道为什么？

我的CSS：

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    textView = (TextView) findViewById(R.id.textView);
    minutesText = (EditText) findViewById(R.id.minutesText);
    secondsText = (EditText) findViewById(R.id.secondsText);
    startButton = (Button) findViewById(R.id.startButton);
    intervalCount = (EditText) findViewById(R.id.intervalCount);






    startButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            if (minutesText.getText().toString().equals("")) {
                minutesInt = 0;
            } else {
                minutesString = minutesText.getText().toString();
                minutesInt = Integer.parseInt(minutesString);

            }

            secondsString = secondsText.getText().toString();
            if (secondsText.getText().toString().equals("")) {
                secondsInt = 0;

            } else {
                secondsString = secondsText.getText().toString();
                secondsInt = Integer.parseInt(secondsString);

            }
            if (intervalCount.getText().toString().equals("")) {
                intervals = 0;
            } else {
                intervalsString = intervalCount.getText().toString();
                intervals = Integer.parseInt(intervalsString);
            }


            final int timerAmount = ((minutesInt * 60) + (secondsInt)) * 1000;



                Log.i("Hello, ", "intervals are " + intervals);
                new CountDownTimer(timerAmount, 1000) {
                    @RequiresApi(api = Build.VERSION_CODES.N)
                    public void onTick(long millisUntilFinished) {
                        activeRunning = true;
                        String timeLeft = String.format("%02d : %02d",
                                TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished),
                                TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) -
                                        TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished))
                        );
                        textView.setText("Reamining: " + timeLeft);
                    }

                    public void onFinish() {

                        textView.setText("FINISHED1");


                        try {
                            Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
                            Ringtone r = RingtoneManager.getRingtone(getApplicationContext(), notification);
                            r.play();
                        } catch (Exception e) {
                            e.printStackTrace();
                        }


                        new CountDownTimer(5000, 1000) {
                            public void onTick(long millisUntilFinished) {
                                restRunning = true;
                                activeRunning = false;
                                String timeLeft = String.format("%02d : %02d",
                                        TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished),
                                        TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) -

                                );
                                textView.setText("Rest: " + timeLeft);
                            }
                            public void onFinish() {
                                restRunning = false;

                                textView.setText("FINISHED2");
                                try {
                                    Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
                                    Ringtone r = RingtoneManager.getRingtone(getApplicationContext(), notification);
                                    r.play();
                                } catch (Exception e) {
                                    e.printStackTrace();
                                }


                            }
                        }.start();

                            if (intervals > 0) {
                                intervals--;
                                this.start();
                            }

            }






    });


}

    }

没有你的HTML很难知道，但我的猜测是它与你的＃3D有关... HTML ID不能从数字开始。尝试将ID更改为以字母开头并更改您的CSS，并查看是否可以修复它。

为什么我的div标题和div消失了？
