Question

如何解决此问题？我检查了所有库，但无法解决。我在行中添加了注释。

    public void onCreate(SQLiteDatabase db)
{
    String CREATE_TABLE = "CREATE TABLE " + TABLE_NAME + "("
            + ID + " INTEGER PRIMARY KEY AUTOINCREMENT,"
            + ifade + " TEXT," + yorum + " TEXT"+")";
    db.execSQL(CREATE_TABLE);
}

public void addanswer(String ifadestring,String yorumstring)
{
    ContentValues values = new ContentValues();
    values.put(ifade, ifadestring);
    values.put(yorum, yorumstring);
    db.insert(TABLE_NAME, null, values); //ERROR cannot find symbol variable db
    db.close(); //ERROR cannot find symbol variable db
}

Answer 1

确保您的db文件具有.db扩展名或其他名称，然后将其放在android软件包中的assest文件夹中

Answer 2

解决方案

public void AnkatorEkle(String ifadestring,String yorumstring)
{
    SQLiteDatabase db = this.getWritableDatabase();
    ContentValues values = new ContentValues();
    values.put(ifade, ifadestring);
    values.put(yorum, yorumstring);
    db.insert(TABLE_NAME, null, values);
    db.close();
}

错误：找不到符号变量db
