如何設置單擊按鈕時彈出的TimePickerDialog？

Question

我一直在嘗試建立一個時間選擇器對話框，用戶可以在其中選擇時間，然后保存時間並將其作為字符串傳遞給下一個活動。

我遵循一些教程並成功設置了DatePickerDialog，但是我仍然無法讓Time Picker對話框正常工作。

這是我的嘗試：

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

    mItemSelectedMessageTemplate =
            getString(R.string.spinner_message_template);
    Spinner spinner = (Spinner) findViewById(R.id.measured_time);
    spinner.setOnItemSelectedListener(new SpinnerInfo());

    dateFormatter = new SimpleDateFormat("yyyy-MM-dd", Locale.TRADITIONAL_CHINESE);
    findViewsById();


    setDateTimeField();
    timeFormatter = new SimpleDateFormat("hh:mm",Locale.TRADITIONAL_CHINESE);
    findViewsById();
    setTimeField();


    editPatientID = (EditText) findViewById(R.id.editPatientID);
    edit_sugar_con = (EditText) findViewById(R.id.edit_sugar_con);
}


private void setDateTimeField() {
    btnSelectDate.setOnClickListener(this);
    //editTime.setOnClickListener(this);

    Calendar newCalendar = Calendar.getInstance();
    DatePickerDialog = new DatePickerDialog(this, new android.app.DatePickerDialog.OnDateSetListener() {

        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
            Calendar newDate = Calendar.getInstance();
            newDate.set(year, monthOfYear, dayOfMonth);
                btnSelectDate.setText(dateFormatter.format(newDate.getTime()));
            }

        }, newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
    }

private void setTimeField(){

    btnSelectTime.setOnClickListener(this);
    Calendar newCalendar = Calendar.getInstance();
    TimePickerDialog = new TimePickerDialog(this, new android.app.TimePickerDialog.OnTimeSetListener(){

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
            Calendar newTime = Calendar.getInstance();
            newTime.set(hourOfDay, minute);
                btnSelectDate.setText(timeFormatter.format(newTime.getTime()));
            }
        }, newCalendar.get(Calendar.HOUR_OF_DAY), newCalendar.get(Calendar.MINUTE));

    }

我嘗試了一些修改代碼，但是仍然有些冒犯性的想法說{/（/;丟失了。

錯誤：

newTime.set(hourOfDay, minute);

對：

Calendar newTime = Calendar.getInstance();
newTime.set(Calendar.HOUR_OF_DAY, hourOfDay);
newTime.set(Calendar.MINUTE, minute);
newTime.set(Calendar.SECOND, 0);
newTime.set(Calendar.MILLISECOND, 0);
