我收到以下錯誤：Cannot resolve method 'newInstance(com.example.ghazalitodo.AddReminderActivity, int, int, boolean)這是我的代碼：public void setTime(View v) { if (mCurrentReminderUri == null) { Toast.makeText(this, "click again on the reminder list to set time alarm", Toast.LENGTH_LONG).show(); return; } Calendar now = Calendar.getInstance(); TimePickerDialog tpd = TimePickerDialog.newInstance(this, now.get(Calendar.HOUR_OF_DAY), now.get(Calendar.MINUTE), false); tpd.setThemeDark(false); tpd.show(getFragmentManager(), "Timepickerdialog");}// On clicking Date pickerpublic void setDate(View v) { if (mCurrentReminderUri == null) { Toast.makeText(this, "click again on the reminder list to set date alarm", Toast.LENGTH_LONG).show(); return; } Calendar now = Calendar.getInstance(); DatePickerDialog dpd = DatePickerDialog.new Instance(this, now.get(Calendar.YEAR), now.get(Calendar.MONTH), now.get(Calendar.DAY_OF_MONTH) ); dpd.show(getFragmentManager(), "Datepickerdialog");}

如果我錯了，請原諒我。我不熟悉那些觀點。但是，我認為你應該使用：
TimePickerDialog tpd = new TimePickerDialog(this, null,
now.get(Calendar.HOUR_OF_DAY), now.get(Calendar.MINUTE), false);
和
DatePickerDialog dpd = new DatePickerDialog (this, null, now.get(Calendar.YEAR),
now.get(Calendar.MONTH), now.get(Calendar.DAY_OF_MONTH);
如果這有幫助，請告訴我。否則，我會刪除我的答案
編輯
我猜你是從某個庫（擴展了 a ）復制了代碼DialogFragment。這就是為什么你有一些沖突。
為了使您的代碼使用這些的默認實現工作Dialog，您可以使用：
public void setTime(View v) {
if (mCurrentReminderUri == null) {
Toast.makeText(this, "click again on the reminder list to set time alarm", Toast.LENGTH_LONG).show();
return;
}
Calendar now = Calendar.getInstance();
TimePickerDialog tpd = new TimePickerDialog(this, null,
now.get(Calendar.HOUR_OF_DAY), now.get(Calendar.MINUTE), false);
tpd.show();
}
// On clicking Date picker
public void setDate(View v) {
if (mCurrentReminderUri == null) {
Toast.makeText(this, "click again on the reminder list to set date alarm", Toast.LENGTH_LONG).show();
return;
}
Calendar now = Calendar.getInstance();
DatePickerDialog dpd = new DatePickerDialog (this, null, now.get(Calendar.YEAR),
now.get(Calendar.MONTH), now.get(Calendar.DAY_OF_MONTH));
dpd.show();
}
