如何設置按鈕單擊時彈出的TimePickerDialog？

我一直在嘗試設置一個時間選擇器對話框，用戶可以選擇時間，然後保存並將時間作爲字符串傳遞給下一個活動。如何設置按鈕單擊時彈出的TimePickerDialog？

我按照一些教程，併成功地設置DatePickerDialog，但我堅持讓時間選取器對話框工作。

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)); 

    }

我想修改我的代碼了一點，但一點紅的頭腦還是來了說{/（/;缺少

你能從控制檯發佈錯誤嗎？ –

我試圖修改我的代碼，但有點紅色的心仍然出現說{/（/;缺少。 –

錯誤：

newTime.set(hourOfDay, minute);

right：

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);
