现在帮助TimePickerDialog和日期

Question

我正在使用一个按钮，用这个方法显示团队的小时和分钟

 private void obtenerFechaActual() {
            final Calendar c = Calendar.getInstance();
            mYear = c.get(Calendar.YEAR);
            mMonth = c.get(Calendar.MONTH);
            mDay = c.get(Calendar.DAY_OF_MONTH);
            mHour = c.get(Calendar.HOUR_OF_DAY);
            mMinute = c.get(Calendar.MINUTE);
        }

            btnSelectTime.setOnClickListener(new View.OnClickListener() {  
                        public void onClick(View v) {
                            // Show the TimePickerDialog
obtenerFechaActual();
                             showDialog(TIME_DIALOG_ID);

                        }
                    });
            @Override
            protected Dialog onCreateDialog(int id) {
            switch (id) {
                 case TIME_DIALOG_ID:
                  return new TimePickerDialog(this,
                  mTimeSetListener, mHour, mMinute, false);
              }
               return null;
         }

            private TimePickerDialog.OnTimeSetListener mTimeSetListener =
             new TimePickerDialog.OnTimeSetListener() {
          public void onTimeSet(TimePicker view, int hourOfDay, int min) {
                                                   hour = hourOfDay;
                                                   minute = min;
                                                   btnSelectTime.setText("Time selected :"+hour+"-"+minute);
                                                 }
                                           };

确实很好，但每次按下按钮，它都会保留按钮第一次点击的分钟和日期。我们的想法是，每次单击按钮，它都会显示当前时间和日期。

添加此方法：

@Override
                           protected void onPrepareDialog(int id, Dialog dialog) {
                               switch (id) {
                                   case TIME_DIALOG_ID:
                                       ((TimePickerDialog) dialog).updateTime(mHour, mMinute);
                                       break;
                                   case DATE_DIALOG_ID:
                                       ((DatePickerDialog) dialog).updateDate(mYear, mMonth, mDay);
                                       break;
                               }
                           }
