错误插入android.database.sqlite.SQLiteDatatypeMismatchException：数据类型不匹配（代码20）

我的问题是关于我的数据库插入语句。我添加了一个参数来插入语句，现在每次我尝试添加一个人时，它都会给出这个错误。我已经改变了数据库版本，但仍然给我一个“数据不匹配”的错误。我添加了这个参数插入语句beaucaus它没有保存ID（字符串），每次我注销时，我所做的（用户名+密码）的ID在一个整数更改..所以我想我的数据库认为该ID整数是但我想它作为一个字符串。我其实认为每种类型都是对的。错误插入android.database.sqlite.SQLiteDatatypeMismatchException：数据类型不匹配（代码20）

这是我的代码，感谢您的帮助！

数据库：

public class DatabaseHelper extends SQLiteOpenHelper { 

private static DatabaseHelper instance; 

//Database Versie 
public static final int database_version = 3; 

//Database Naam 
public static final String DATABASE_NAME = "Biercafevlaanderen.db"; 

//Tabel Namen 
public static final String TABLE_NAME_PROFIELEN = "profielen"; 
public static final String TABLE_NAME_BIERCAFES = "biercafes"; 

//Kollom namen 
// voor tabel profiles 
public static String COL_1_PROFIELEN= "profile_id"; 
public static final String COL_2_PROFIELEN= "username"; 
public static final String COL_3_PROFIELEN = "firstname"; 
public static final String COL_4_PROFIELEN = "email"; 
public static final String COL_5_PROFIELEN = "password";

public static final String COL_2_BIERCAFES = "biercafe_name"; 
public static final String COL_3_BIERCAFES = "biercafe_postcode"; 
public static final String COL_4_BIERCAFES = "biercafe_plaats"; 
public static final String COL_5_BIERCAFES = "biercafe_gemeente"; 
public static final String COL_6_BIERCAFES = "biercafe_omschrijving";

public static final String COL_9_BIERCAFES = "biercafe_email"; 
public static final String COL_10_BIERCAFES = "profielid"; 


public static synchronized DatabaseHelper getInstance(Context context) { 
    if (instance == null) { 
     instance = new DatabaseHelper(context.getApplicationContext()); 
    } 
    return instance; 
} 

public DatabaseHelper(Context context) { 
    super(context, DATABASE_NAME, null, database_version); 
    SQLiteDatabase db = this.getWritableDatabase(); 
} 

//HERE FALLS THE ERROR 
public int insertProfiel (String id,String username, String password) { 
    SQLiteDatabase db = this.getWritableDatabase(); 
    ContentValues contentValues = new ContentValues(); 
    contentValues.put(COL_1_PROFIELEN,id); 
    contentValues.put(COL_2_PROFIELEN, username); 
    contentValues.put(COL_5_PROFIELEN, password); 

    // de insert methode geeft -1 terug als het niet gelukt is en de row value als het wel gelukt is 
    long result = db.insert(TABLE_NAME_PROFIELEN, null, contentValues); 

    return (int)result; 
} 
@Override 
public void onCreate(SQLiteDatabase db) { 
    // de tabel creëren voor de profielen 
    db.execSQL("CREATE TABLE IF NOT EXISTS " + TABLE_NAME_PROFIELEN + " (" +  COL_1_PROFIELEN + " INTEGER PRIMARY KEY AUTOINCREMENT, " + COL_2_PROFIELEN + " VARCHAR(255), " + COL_3_PROFIELEN + " VARCHAR(255), " + COL_4_PROFIELEN + " VARCHAR(255), " + COL_5_PROFIELEN + " VARCHAR(255))"); 

    // de tabel creëren voor de locaties met foreign key profile_id 
    db.execSQL("CREATE TABLE IF NOT EXISTS " + TABLE_NAME_BIERCAFES + " (" + COL_1_BIERCAFES + " INTEGER PRIMARY KEY, " + COL_2_BIERCAFES + " VARCHAR(255), " + COL_3_BIERCAFES + " VARCHAR(255), " + COL_4_BIERCAFES + " VARCHAR(255), " + COL_5_BIERCAFES + " VARCHAR(255), " + COL_6_BIERCAFES +

} 

@Override 
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME_PROFIELEN); 
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME_BIERCAFES); 
    onCreate(db); 
} 
}

这是我在DB 注册插入用户：

Profiel p = new Profiel(etUsername.getText().toString()+""+etPassword.getText().toString(),etUsername.getText().toString(),"","",etConfPass.getText().toString()); 
           mListener.getMyDB().insertProfiel(p.getId(),p.getUsername(), p.getPassword()); 
           System.out.println(mListener.getMyDB().insertProfiel(p.getId(),p.getUsername(), p.getPassword())); 
           Intent intent = new Intent(getActivity(), MainActivity.class); 
           intent.putExtra("profiel", p.toJson()); 
           Snackbar.make(v, "Registered succesfully", Snackbar.LENGTH_LONG) 
             .setAction("Action", null).show(); 
           startActivity(intent); 
           getActivity().finish();

如果需要其他relavent班，问我。这是错误：

E/SQLiteLog: (20) statement aborts at 5: [INSERT INTO profielen(password,username,profile_id) VALUES (?,?,?)] datatype mismatch

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:779)

的insertstatement给了我这样的：

I/System.out: -1

感谢您的帮助！

public int insertProfiel (Stringid,String username, String password) { SQLiteDatabase db = this.getWritableDatabase(); ContentValues contentValues = new ContentValues(); contentValues.put(COL_1_PROFIELEN,id); contentValues.put(COL_2_PROFIELEN, username); contentValues.put(COL_5_PROFIELEN, password); //rest of the code }

id不应该是String，而是Integer。这就是为什么你得到这个错误，因为当你创建表PROFILIEN时，你声明COL_1_PROFILIEN（profilien_id）是一个INTEGER。

db.execSQL("CREATE TABLE IF NOT EXISTS " + TABLE_NAME_PROFIELEN + " (" + COL_1_PROFIELEN + " INTEGER PRIMARY KEY AUTOINCREMENT, " + COL_2_PROFIELEN + " VARCHAR(255), " + COL_3_PROFIELEN + " VARCHAR(255), " + COL_4_PROFIELEN + " VARCHAR(255), " + COL_5_PROFIELEN + " VARCHAR(255))");

但我想它作为一个字符串，因为我的ID =用户名+密码，这个组合是一个字符串，我在哪里说ID必须是一个整数？ – Peter

我相信你应该保持原样（INTEGER PRIMARY KEY AUTOINCREMENT），因为这不是你正在尝试做的一个好习惯。您正试图在您的数据库上创建冗余数据，因为不需要将两个字段放在另一个字段中，仍然保留所有这些字段。 –

非常感谢！我改变了我的第一列的类型，现在它的话:)！ – Peter
