Я пытаюсь implemente андроид приложение, которое получает смс и сохраняются его в местном dabase, здесь мы будем использовать Sqlite,найти Crud SQLITE андроида реализации
в моей основной деятельности я стараюсь оставаться смс, а затем , я стараюсь читать его из моей базы данных, но я не могу, ль найти() строка никогда не выполняется (то, что говорит мои журналы), вот какой-то код моей основной деятельности:
CSmsReceiverDAO cSmsReceiverDAO = new CSmsReceiverDAO(this);
CSmsReceived SmsReceived1 = new CSmsReceived.SmsReceivedBuilder()
.Data("coords XY").DateReceiving("janvier").Phone("+33565456").Processed("zz").build();
cSmsReceiverDAO.open();
try {
Log.i("test","try ok");
cSmsReceiverDAO.persist(SmsReceived1);
Log.i("test", "persist ok");
CSmsReceived smsFromBdd = cSmsReceiverDAO.find(SmsReceived1.getDateReceiving());
Log.i("test", "find ok");
if (smsFromBdd !=null){
Toast.makeText(this, smsFromBdd.toString(), Toast.LENGTH_LONG).show();
}
else {
Toast.makeText(this, "persist fail...", Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
e.printStackTrace();
}
и мои журналы:
02-19 07:19:23.087 2837-2837/? I/test: try ok
02-19 07:19:23.087 2837-2837/? I/test: persist ok
, но у меня нет строки «find ok».
вот как я построю свои смс (я использую строитель шаблон):
public class CSmsReceived implements Serializable{
private final String dateReceiving; // optional
private final String processed; // optional
private final String phone; // optional
private final String data; // optional
private CSmsReceived(SmsReceivedBuilder builder) {
this.dateReceiving = builder.dateReceiving;
this.processed = builder.processed;
this.phone = builder.phone;
this.data = builder.data;
}
public String getDateReceiving() {
return dateReceiving;
}
public String getProcessed() {
return processed;
}
public String getPhone() {
return phone;
}
public String getData() {
return data;
}
public String toString(){
return "dateReceiving : " + dateReceiving + " processed : " + processed +"\n"
+ " phone : " + phone + " data : " + data;
}
public static class SmsReceivedBuilder {
private String dateReceiving;
private String processed;
private String phone;
private String data;
public SmsReceivedBuilder Data(String data) {
this.data = data;
return this;
}
public SmsReceivedBuilder DateReceiving(String dateReceiving) {
this.dateReceiving = dateReceiving;
return this;
}
public SmsReceivedBuilder Phone(String phone) {
this.phone = phone;
return this;
}
public SmsReceivedBuilder Processed(String processed) {
this.processed = processed;
return this;
}
public CSmsReceived build() {
return new CSmsReceived(this);
}
}
}
и вот моя база данные создания: (подключение и создавать таблицы)
редактировать: Попробуйте CREATE TABLE IF NOT сУЩЕСТВУЕТ - @Prithviraj Shiroor, но это ничего не меняет
public class CMaBaseSQLite extends SQLiteOpenHelper {
private static final String COL_ID = "ID";
private static final String TABLE_SMS_SENT = "table_sms_sent";
private static final String COL_DateSending = "dateSending";
private static final String TABLE_SMS_RECEIVED = "table_sms_received";
private static final String COL_DateReceiving = "dateReceiving";
private static final String COL_PROCESSED ="processed";
private static final String COL_PHONE ="phone";
private static final String COL_DATA ="data";
private static final String CREATE_BDD_SMS_RECEIVED = "CREATE TABLE IF NOT EXISTS " + TABLE_SMS_RECEIVED + " ("
+ COL_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + COL_DateReceiving + " TEXT, "
+ COL_PROCESSED + " TEXT, " + COL_PHONE + " TEXT, " + COL_DATA + " TEXT);";
private static final String CREATE_BDD_SMS_SENT = "CREATE TABLE IF NOT EXISTS" + TABLE_SMS_SENT + " ("
+ COL_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + COL_DateSending + " TEXT, "
+ COL_PHONE + " TEXT, " + COL_DATA + " TEXT NOT NULL);";
public CMaBaseSQLite(Context context, String name, CursorFactory factory, int version) {
super(context, name, factory, version);
}
@Override
public void onCreate(SQLiteDatabase db) {
//on créé la table à partir de la requête écrite dans la variable CREATE_BDD sent et received
db.execSQL(CREATE_BDD_SMS_RECEIVED);
db.execSQL(CREATE_BDD_SMS_SENT);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
//On peut fait ce qu'on veut ici moi j'ai décidé de supprimer la table et de la recréer
//comme ça lorsque je change la version les id repartent de 0
db.execSQL("DROP TABLE " + TABLE_SMS_SENT + ";");
db.execSQL("DROP TABLE IF EXISTS " + TABLE_SMS_RECEIVED + ";");
onCreate(db);
}
}
и, наконец, моя smsDAO:
EDIT: упорствовать метод debuged
values.put(t.getDateReceiving(), NUM_COL_DateReceiving);
values.put(t.getProcessed(), NUM_COL_PROCESSED);
values.put(t.getPhone(), NUM_COL_PHONE);
values.put(t.getData(), NUM_COL_DATA);
=>
values.put(COL_DateReceiving,t.getDateReceiving());
values.put(COL_PROCESSED, t.getProcessed());
values.put(COL_PHONE, t.getPhone());
values.put(COL_DATA, t.getData());
теперь мой код:
public class CSmsReceiverDAO implements IDAO<CSmsReceived> {
private SQLiteDatabase bdd;
private CMaBaseSQLite cMaBaseSQLite;
private static final String NOM_BDD = "sms.db";
private static final int VERSION_BDD = 1;
private static final String COL_ID = "ID";
private static final int NUM_COL_ID = 0;
private static final String TABLE_SMS_SENT = "table_sms_sent";
private static final String COL_DateSending = "dateSending";
private static final String TABLE_SMS_RECEIVED = "table_sms_received";
private static final String COL_DateReceiving = "dateReceiving";
private static final int NUM_COL_DateReceiving = 1;
private static final String COL_PROCESSED ="processed";
private static final int NUM_COL_PROCESSED = 2;
private static final String COL_PHONE ="phone";
private static final int NUM_COL_PHONE= 3;
private static final String COL_DATA ="data";
private static final int NUM_COL_DATA= 4;
public CSmsReceiverDAO(Context context){
//On créer la BDD et sa table
cMaBaseSQLite = new CMaBaseSQLite(context, NOM_BDD, null, VERSION_BDD);
}
public void open(){
//on ouvre la BDD en écriture
bdd = cMaBaseSQLite.getWritableDatabase();
}
public void close(){
//on ferme l accès à la BDD
bdd.close();
}
public SQLiteDatabase getBDD(){
return bdd;
}
@Override
public CSmsReceived find(String date) throws Exception {
//Récupère dans un Cursor les valeur correspondant à un livre contenu dans la BDD (ici on sélectionne le livre grâce à son titre)
Cursor c = bdd.query(TABLE_SMS_RECEIVED, new String[] {COL_ID, COL_DateReceiving, COL_PROCESSED, COL_PHONE, COL_DATA}, COL_DateReceiving + " LIKE \"" + date +"\"", null, null, null, null);
return cursorToSms(c);
}
@Override
public List<CSmsReceived> findAll() throws Exception {
return null;
}
@Override
public void persist(CSmsReceived t) throws Exception {
//Création d un ContentValues (fonctionne comme une HashMap)
ContentValues values = new ContentValues();
//on lui ajoute une valeur associé à une clé (qui est le nom de la colonne dans laquelle on veut mettre la valeur)
values.put(COL_DateReceiving,t.getDateReceiving());
values.put(COL_PROCESSED, t.getProcessed());
values.put(COL_PHONE, t.getPhone());
values.put(COL_DATA, t.getData());
//on insère l objet dans la BDD via le ContentValues
bdd.insert(TABLE_SMS_RECEIVED, null, values);
}
@Override
public void remove(CSmsReceived t) throws Exception {
}
@Override
public void update(CSmsReceived s, CSmsReceived t) throws Exception {
}
@Override
public void refresh(CSmsReceived t) throws Exception {
}
//Cette méthode permet de convertir un cursor en un sms
private CSmsReceived cursorToSms(Cursor c){
//si aucun élément n a été retourné dans la requête, on renvoie null
if (c.getCount() == 0)
return null;
//Sinon on se place sur le premier élément
c.moveToFirst();
//On créé un sms
//on lui affecte toutes les infos grâce aux infos contenues dans le Cursor
CSmsReceived cSmsReceived = new CSmsReceived.SmsReceivedBuilder()
.DateReceiving(c.getString(NUM_COL_DateReceiving))
.Processed(c.getString(NUM_COL_PROCESSED)).Phone(c.getString(NUM_COL_PHONE))
.Data(c.getString(NUM_COL_DATA)).build();
//On ferme le cursor
c.close();
//On retourne le livre
return cSmsReceived;
}
}
так почему мой метод находкой не работает?
как @Elite говорит, бревенчатый кошка может быть интересно (журнал обновляется):

У вас есть лицо по ошибке..если так предоставить лог-код. – ELITE
вы правы, я просто вижу странное сообщение и действительно интересно (я его публикую) – boblinux
Это означает, что таблица не присутствует – ELITE
