我正在使用此代码显示警告对话框…当我点击确定按钮时,它应显示日期选择器..
protected Dialog onCreateDialog(int id) {
switch (id) {
case TIME_DIALOG_ID:
return new TimePickerDialog(ListReminderActivity.this,mTimeSetListener,mHour,mMinute,false);
case DATE_DIALOG_ID:
return new DatePickerDialog(ListReminderActivity.this,mDateSetListener,mYear,mMonth,mDay);
case DESCRIPTION_DIALOG_ID:
return new AlertDialog.Builder(ListReminderActivity.this).setTitle(
"Add Reminder").setView(description).setPositiveButton(
R.string.add_alert_ok,new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int whichButton) {
ListReminderActivity.this
.dismissDialog(DESCRIPTION_DIALOG_ID);
ListReminderActivity.this
.removeDialog(DESCRIPTION_DIALOG_ID);
ListReminderActivity.this
.showDialog(DATE_DIALOG_ID);
}
}).setNegativeButton(R.string.add_alert_cancel,int whichButton) {
ListReminderActivity.this
.dismissDialog(DESCRIPTION_DIALOG_ID);
ListReminderActivity.this
.removeDialog(DESCRIPTION_DIALOG_ID);
}
}).create();
}
return null;
}
但问题是..当我按下确定按钮时,我得到了例外
例外是……

解决方法
如您在日志中看到的错误所示,您的mYear,mMonth或mDay值之一无效.
