を使用したとき、私はフラグメントを使用する場合、私が完全なコードを貼り付け、それはここで日付ピッカーは私がフラグメント
Error:(63, 61) error: incompatible types: MainActivity cannot be converted to Context
のようなエラーを発生させる活動に取り組んでいるDatePickerを設定する機能していません。

}
}
このコードは動作しません： -
fromDatePickerDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Calendar newDate = Calendar.getInstance();
newDate.set(year, monthOfYear, dayOfMonth);
fromDateEtxt.setText(dateFormatter.format(newDate.getTime()));
}
},newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
私はそれを試してみましたが、それは何度も何度も同じエラーが発生している。..
