sqlite資料庫中第一條資料查不出來！

標籤：

/**
*  * Title: selectAllPhone  *Description:查詢所有的Phone對象  * @return  * @see
* com.sms.ntlm.dao.PhoneDao#selectAllPhone()     
*/
@SuppressLint("SimpleDateFormat")
@SuppressWarnings("deprecation")
@Override
public List<Phone> selectAllPhone() {
Cursor cursor=null;
List<Phone> list=new ArrayList<Phone>();
String sql="select * from "+PhoneSQLConstant.TABLE_NAME+";";
db=mOpenHelper.getWritableDatabase();
if(mOpenHelper!=null && db.isOpen()){
// cursor=db.query(PhoneSQLConstant.TABLE_NAME, null, null, null, null, null, null);
cursor=db.rawQuery(sql, null);
}
if (cursor != null) {//原因就是這個地方出錯了：我在這個地方加了個if (cursor != null && cursor.moveToFirst()) {
while (cursor.moveToNext()) {
Phone phone=new Phone();

phone.setPhoneId(cursor.getInt(cursor.getColumnIndex(PhoneSQLConstant.PHONE_ID)));
phone.setPhoneNum(cursor.getString(cursor.getColumnIndex(PhoneSQLConstant.PHONE_NUM)));
phone.setPhoneDate(cursor.getString(cursor.getColumnIndex(PhoneSQLConstant.PHONE_DATE)));

list.add(phone);
}
}
this.closeCursorDB(cursor);
return list;

}

控制台輸出的結果是:05-15 03:12:44.017: I/System.out(12634): testselectAllPhone.size()..............0

我在資料庫中查詢的結果是：
