Question

我希望用两个条件选择sqlite数据库中的所有数据，＆＃34;日期＆＃34;安达＆＃34;时间＆＃34;。日期格式为＆＃34; dd / mm / yyy或01/12 / 2014＆＃34;时间是＆＃34; hh：mm或17:15＆＃34;。

Bellow是我的databasehandler中的代码

public List getMessageToSent（String Date，String Time）{

    List<TestSaving> savingList = new ArrayList<TestSaving>();

    String query = "Select " + KEY_ROWID + "," + KEY_CONTACT_NAME + ","
            + KEY_CONTACT_NO + "," + KEY_CONTACT_MESSAGE + ","
            + KEY_CONTACT_PICTURE + " from testsaving where "
            + KEY_CONTACT_DATESEND + " = " + Date + " AND "
            + KEY_CONTACT_TIMESEND + " = " + Time + " order by "
            + KEY_CONTACT_NAME;

    SQLiteDatabase db = this.getWritableDatabase();
    Cursor cursor = db.rawQuery(query, null);

    if (cursor.moveToFirst()) {
        do {
            TestSaving testSave = new TestSaving();
            testSave.set_contact_id(Integer.parseInt(cursor.getString(0)));
            testSave.set_contact_name(cursor.getString(1));
            testSave.set_contact_no(cursor.getString(2));
            testSave.set_contact_message(cursor.getString(3));
            testSave.set_contact_picture(cursor.getBlob(4));

            savingList.add(testSave);
        } while (cursor.moveToNext());
    }

    db.close();
    return savingList;
}

和bellow是我在BroadCastReceiver Class中的代码

@Override
public void onReceive(Context context, Intent intent) {
    DataBaseHandler db = new DataBaseHandler(context);

    final Calendar c = Calendar.getInstance();
    int year = c.get(Calendar.YEAR);
    int month = c.get(Calendar.MONTH);
    int day = c.get(Calendar.DAY_OF_MONTH);
    int hour = c.get(Calendar.HOUR_OF_DAY);
    int minute = c.get(Calendar.MINUTE);

    Date = new StringBuilder().append(Utility.utilTime(day)).append("/")
            .append(Utility.utilTime(month)).append("/")
            .append(Utility.utilTime(year));

    Time = new StringBuilder().append(Utility.utilTime(hour)).append("/")
            .append(Utility.utilTime(minute));

    List<TestSaving> testSavings = db.getMessageToSent(Date.toString(),
            Time.toString());

    for (TestSaving ts : testSavings) {
        String log = "contact_id:" + ts.get_contact_id()
                + " ,contact_name: " + ts.get_contact_name()
                + " ,contact_no: " + ts.get_contact_no()
                + " ,contact_message: " + ts.get_contact_message()
                + " ,contact_picture: " + ts.get_contact_picture();

        Log.d("Result: ", log);


        Notification(context, Date + " dan " + Time);
    }

}

当我查看日志时，我不会收到错误。可以有人，告诉我如何解决它？

P.s接收器可以正常处理虚拟数据，

检索数据库中的数据并将其显示在android中的broadcastreceiver中的通知中
