Android SQLite不存在此类表

我有一个在同一个数据库中使用2个表的应用程序。我在辅助类中创建并预填充这些表,如下所示。

public void onCreate(SQLiteDatabase db) {

    String sql = "CREATE  TABLE [weekmenu] ([weekmenuID] INTEGER PRIMARY KEY  AUTOINCREMENT  NOT NULL  UNIQUE, [receptenLijst] VARCHAR(50) NOT NULL )";
    db.execSQL(sql);

    sql = "INSERT INTO weekmenu (receptenLijst) values('0')"; db.execSQL(sql);


    sql = "CREATE  TABLE [recepten] ([receptID] INTEGER PRIMARY KEY  AUTOINCREMENT  NOT NULL  UNIQUE, [receptNaam] TEXT NOT NULL  UNIQUE, [receptURL] TEXT )";
    db.execSQL(sql);

    sql = "INSERT INTO recepten (receptNaam, receptURL) values('Macaroni met spek en broccoli', 'http://www.kooknet.be/recepten/hoofdgerecht/macaroni-met-spek-en-broccoli')"; db.execSQL(sql);
    sql = "INSERT INTO recepten (receptNaam, receptURL) values('Broccolipuree met spekblokjes en fishsticks', 'http://www.kooknet.be/recepten/hoofdgerecht/broccolipuree-met-spekblokjes-en-fishsticks')"; db.execSQL(sql);
    sql = "INSERT INTO recepten (receptNaam, receptURL) values('Hoeveomelet', 'http://www.kooknet.be/recepten/hoofdgerecht/hoeveomelet')"; db.execSQL(sql);
    sql = "INSERT INTO recepten (receptNaam, receptURL) values('Gevulde courgettes', 'http://www.kooknet.be/recepten/hoofdgerecht/gevulde-courgettes')"; db.execSQL(sql);   

}

在另一项活动中,我想确保用户可以在按下按钮时更新表格周菜单。每次用户点击按钮时,周围菜单中的相同记录应该被覆盖(通过更新表格)

        btnWeekmenuOpslaan.setOnClickListener(new View.OnClickListener() {
        // Database aanroepen
        SQLiteDatabase db = oData.getReadableDatabase();

        @Override
        public void onClick(View v) {


            ContentValues values = new ContentValues();
            String receptenLijst =
                    txtMaandagReceptID.getText().toString() + "-" +
                    txtDinsdagReceptID.getText().toString() + "-" +
                    txtWoensdagReceptID.getText().toString() + "-" +
                    txtDonderdagReceptID.getText().toString() + "-" +
                    txtVrijdagReceptID.getText().toString() + "-" +
                    txtZaterdagReceptID.getText().toString() + "-" +
                    txtZondagReceptID.getText().toString();

            // database updaten
            values.put("receptenLijst", receptenLijst);         
            db.update("weekmenu", values, "weekmenuID=?",new String[] {Long.toString(1)});
            db.close();
            oData.close();              
        }
    });

不幸的是,活动停止,在调试模式下,我收到“周菜单:没有这样的表存在”的消息。

有人能帮帮我吗?我一直在阅读Stackoverflow上的很多帖子,但没有一个能帮助我。

谢谢!

你的罪魁祸首在这里:

SQLiteDatabase db = oData.getReadableDatabase();

您需要一个可写数据库。不可读。

将其更改为:

QLiteDatabase db = oData.getWritableDatabase();
