我正在嘗試分配用戶輸入到編輯文本中的值作為倒計(jì)時(shí)器的起始值，將其轉(zhuǎn)換為毫秒     @Override    protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    minutes = (EditText) findViewById(R.id.minutes);    seconds = (EditText) findViewById(R.id.seconds);    start = (Button) findViewById(R.id.startbutton);    count = (TextView) findViewById(R.id.counting);    final String sec = String.valueOf(seconds.getText());    int sec1 = Integer.valueOf(sec);    long sec2 = sec1;    //String minu = minutes.getText().toString();     final CountDownTimer counting = new        CountDownTimer(TimeUnit.SECONDS.toMillis(sec2), 1000) {           @Override           public void onTick(long millisUntilFinished) {               Log.i("alarm rings in",                                         String.valueOf(millisUntilFinished/1000));           }           @Override            public void onFinish() {                Log.i("done", "alarm is ringing");            }        };    start.setOnClickListener(new View.OnClickListener() {        @Override        public void onClick(View v) {            counting.start();        }    });}}我期望單擊按鈕后開(kāi)始倒計(jì)時(shí)，但它顯示 Onfinish() 方法輸出
