Android中的自定義對話框中的日期選擇器

我想在我的自定義對話框中使用日期選擇器。在按鈕上單擊日曆將打開以選擇用戶的日期。我有我的customDilaog類中的按鈕，並在該按鈕上點擊我想打開日曆視圖。點擊此按鈕，我的應用程序崩潰。我已經完成了這一點。Android中的自定義對話框中的日期選擇器

CustomDialog.java

public class CustomDialog extends Dialog implements android.view.View.OnClickListener { 

    private Button date; 
    DateFormat format = DateFormat.getDateInstance(); 
    Calendar calender = Calendar.getInstance(); 

    public CustomDialog(Context context) { 
     super(context); 
    } 

    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
       date=(Button)findViewById(R.id.dateText2); 
    } 
    public void onClick(View v) { 
     if (v.getId()==R.id.datePick) { 
      openDatePicker(v); 
     //another if-else statements 
     } 

    public void updateDate(){ 
      date.setText(format.format(calender.getTime())); 
    } 

    public void setDate(){ 
      new DatePickerDialog(getContext(),dp,calender.get(Calendar.YEAR) ,calender.get(Calendar.MONTH),calender.get(Calendar.DAY_OF_MONTH)).show();     
    } 

     DatePickerDialog.OnDateSetListener dp = new DatePickerDialog.OnDateSetListener() { 

     @Override 
     public void onDateSet(DatePicker view, int year, int monthOfYear,int dayOfMonth) { 
       calender.set(Calendar.YEAR,year); 
       calender.set(Calendar.MONTH, monthOfYear); 
       calender.set(Calendar.DAY_OF_MONTH, dayOfMonth); 
       updateDate();     
      } 
     }; 
    }

我不知道我在哪裏出錯了。

郵政錯誤日誌。 – Simas

@Blackbelt openDatePicker是我的onClick xml方法。 –

'錯誤日誌'java.lang.IllegalStateException：無法在活動類中找到方法openDatePicker（View）android.view.ContextThemeWrapper for onClick處理程序查看類android.widget.Button，id爲'dateText2' –

使用這種適當

@OnClick(R.id.fab) 
public void fabbuttonclicked(){ 
    // get prompts.xml view 
    LayoutInflater layoutInflater = LayoutInflater.from(context.getContext()); 

     View promptView = layoutInflater.inflate(R.layout.dialog_add_new_book, null);
