應用程序崩潰而不是彈出日期選擇器對話框

我想在點擊EditText時彈出日期選擇器對話框。我跟着幾個SO帖子和教程，但沒有彈出，然後應用程序在一段時間後崩潰。應用程序崩潰而不是彈出日期選擇器對話框

我不確定這是否是正確的方式來做到這一點，或者我失去了一些東西。任何幫助表示讚賞！

到目前爲止我的代碼，Activity.java的onCreate：

inputDate = (EditText) findViewById(R.id.inputDate); 
    calendar = Calendar.getInstance(); 

    final DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() { 

     @Override 
     public void onDateSet(DatePicker view, int year, int monthOfYear, 
           int dayOfMonth) { 
      // TODO Auto-generated method stub 
      calendar = Calendar.getInstance(); 
      calendar.set(Calendar.YEAR, year); 
      calendar.set(Calendar.MONTH, monthOfYear); 
      calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth); 
      updateLabel(); 
     } 

    }; 

    inputDate.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      // TODO Auto-generated method stub 
      new DatePickerDialog(getApplicationContext(), date, calendar 
        .get(Calendar.YEAR), calendar.get(Calendar.MONTH), 
        calendar.get(Calendar.DAY_OF_MONTH)).show(); 
     } 
    });

updateLabel：

private void updateLabel() { 

    String myFormat = "MM/dd/yy"; //In which you need put here 
    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US); 

    inputDate.setText(sdf.format(calendar.getTime())); 
}

XML：

<EditText 
        android:id="@+id/inputDate" 
        android:layout_width="match_parent" 
        android:layout_height="wrap_content" 
        android:hint="mm/dd/ yyyy" 
        android:imeOptions="actionDone" 
        android:focusable="false" 
        />

錯誤的logcat：

日誌說什麼？：D – XxGoliathusxX

更新了帖子，錯誤logcat – skbrhmn

那是我的，它運作良好：

DatePickerDialogdatePickerDialog = new DatePickerDialog(this, R.style.DialogTheme, new DatePickerDialog.OnDateSetListener() { 
    @Override 
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { 
     //Magic happens here 
    } 
}, nowYear, nowMonth, nowDay); 
datePickerDialog.show();

我試過這個。我仍然有同樣的問題。 – skbrhmn

比它的因爲你的edittext – XxGoliathusxX

任何想法它可能是什麼？這是一個普通的EditText。我會嘗試在空閒活動中做這件事，看看是否有其他事情導致問題。 – skbrhmn
