我正在尝试创建一个应用程序，我需要创建两个表寄存器n的详细信息。我希望注册用户可以登录，然后他们可以保存他们的详细信息。但任何人都可以告诉我如何在这两个表之间建立这种联系。我尝试这样做，但得到错误。

（PasswordKeeperDb.java）

public class PasswordKeeperDb {
private static final int DATABASE_VERSION = 1;
private DbHelper dbHelper;
private SQLiteDatabase sqLiteDatabase;
public static final String DATABASE_NAME = "PasswordKeeper";
private static final String REGISTER_TABLE_NAME = "RegisterTable";
private static final String DETAIL_TABLE_NAME = "DetailsTable";


private static String FIRST_NAME = "firstName", LAST_NAME = "lastName", EMAIL = "email",
        PASSWORD = "password", LOGIN_ID = "loginId", DETAIL_ID = "detailsId", TITLE = "title";


private static final String REGISTER_TABLE_CREATE = "CREATE TABLE IF NOT EXISTS "
        + REGISTER_TABLE_NAME
        + "("
        + LOGIN_ID
        + " INTEGER PRIMARY KEY AUTOINCREMENT , "
        + FIRST_NAME
        + " VARCHAR(80) , "
        + LAST_NAME
        + " VARCHAR(80) , "
        + EMAIL
        + " VARCHAR(80) , "
        + PASSWORD
        + " VARCHAR(80) ) ";

private static final String DETAIL_TABLE_CREATE = "CREATE TABLE IF NOT EXISTS "
        + DETAIL_TABLE_NAME
        + "("
        + DETAIL_ID
        + " INTEGER PRIMARY KEY AUTOINCREMENT , "
        + LOGIN_ID
        + " INTEGER ,"
        + TITLE
        + " VARCHAR(80) , "
        + EMAIL
        + " VARCHAR(80) , "
        + PASSWORD
        + " VARCHAR(10) , )";



private static class DbHelper extends SQLiteOpenHelper {

    public DbHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);

    }

    @Override
    public void onCreate(SQLiteDatabase db) {

        db.execSQL(REGISTER_TABLE_CREATE);
        db.execSQL(DETAIL_TABLE_CREATE);

    }

    @Override

}


public PasswordKeeperDb(Context c) {
    dbHelper = new DbHelper(c);
}

public long insertRegisterTable(final RegisterModel registerModel)
        throws SQLException {
    ContentValues values = new ContentValues();
    values.put(FIRST_NAME, registerModel.getFname());
    values.put(LAST_NAME, registerModel.getLname());
    values.put(EMAIL, registerModel.getEmail());
    values.put(PASSWORD, registerModel.getPassword());
    return sqLiteDatabase.insert(REGISTER_TABLE_NAME, null, values);
}

public long insertDetailTable(final AddModel addModel)
        throws SQLException {
    ContentValues values = new ContentValues();
    values.put(LOGIN_ID, addModel.getLoginId());
    values.put(TITLE, addModel.getTitle());
    values.put(EMAIL, addModel.getEmail());
    values.put(PASSWORD, addModel.getPassword());
    return sqLiteDatabase.insert("DetailsTable", null, values);
}

首先纠正您的 DETAIL_TABLE_CREATE 

 private static final String DETAIL_TABLE_CREATE  =
            "CREATE TABLE " + TABLE_TEAM + " ("
                    + DETAIL_ID + " INTEGER PRIMARY KEY AUTOINCREMENT ,"
                    + LOGIN_ID + " INTEGER ,"
                    + TITLE + " VARCHAR(80) ,"
                    + EMAIL + " VARCHAR(80) ,"
                    + PASSWORD + " VARCHAR(10)" + ")";

然后清理重建和卸载OLD应用并再次运行

请找到正确的代码： - 

public class PasswordKeeperDb {
private static final int DATABASE_VERSION = 1;
private DbHelper dbHelper;
private SQLiteDatabase sqLiteDatabase;
public static final String DATABASE_NAME = "PasswordKeeper";
private static final String REGISTER_TABLE_NAME = "RegisterTable";
private static final String DETAIL_TABLE_NAME = "DetailsTable";


private static String FIRST_NAME = "firstName", LAST_NAME = "lastName", EMAIL = "email",
        PASSWORD = "password", LOGIN_ID = "loginId", DETAIL_ID = "detailsId", TITLE = "title";


private static final String REGISTER_TABLE_CREATE = "CREATE TABLE IF NOT EXISTS "
        + REGISTER_TABLE_NAME
        + "("
        + LOGIN_ID
        + " INTEGER PRIMARY KEY AUTOINCREMENT , "
        + FIRST_NAME
        + " VARCHAR(80) , "
        + LAST_NAME
        + " VARCHAR(80) , "
        + EMAIL
        + " VARCHAR(80) , "
        + PASSWORD
        + " VARCHAR(80) ) ";

private static final String DETAIL_TABLE_CREATE = "CREATE TABLE IF NOT EXISTS "
        + DETAIL_TABLE_NAME
        + "("
        + DETAIL_ID
        + " INTEGER PRIMARY KEY AUTOINCREMENT , "
        + LOGIN_ID
        + " INTEGER ,"
        + TITLE
        + " VARCHAR(80) , "
        + EMAIL
        + " VARCHAR(80) , "
        + PASSWORD
        + " VARCHAR(10) )";



private static class DbHelper extends SQLiteOpenHelper {

    public DbHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);

    }

    @Override
    public void onCreate(SQLiteDatabase db) {

        db.execSQL(REGISTER_TABLE_CREATE);
        db.execSQL(DETAIL_TABLE_CREATE);

    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    }
}


public PasswordKeeperDb(Context c) {
    dbHelper = new DbHelper(c);
}

public long insertRegisterTable(final RegisterModel registerModel)
        throws SQLException {
    ContentValues values = new ContentValues();
    values.put(FIRST_NAME, registerModel.getFname());
    values.put(LAST_NAME, registerModel.getLname());
    values.put(EMAIL, registerModel.getEmail());
    values.put(PASSWORD, registerModel.getPassword());
    return sqLiteDatabase.insert(REGISTER_TABLE_NAME, null, values);
}

public long insertDetailTable(final AddModel addModel)
        throws SQLException {
    ContentValues values = new ContentValues();
    values.put(LOGIN_ID, addModel.getLoginId());
    values.put(TITLE, addModel.getTitle());
    values.put(EMAIL, addModel.getEmail());
    values.put(PASSWORD, addModel.getPassword());
    return sqLiteDatabase.insert("DetailsTable", null, values);
}


public PasswordKeeperDb open() throws SQLException {
    sqLiteDatabase = dbHelper.getWritableDatabase();
    sqLiteDatabase = dbHelper.getReadableDatabase();
    return this;
}


public Cursor getUser(String email, String pass) {
    return sqLiteDatabase.rawQuery("select * from " + REGISTER_TABLE_NAME + " where email=" + "'" + email +
            "' and password=" + "'" + pass + "'", null);
}

public Cursor getLoginId(String email) {
    return sqLiteDatabase.rawQuery("select loginId from " + REGISTER_TABLE_NAME + " where email=" + "'" + email +
            "'", null);
}

public void close() {
    dbHelper.close();
}

您最后在创建明细表上添加了额外的逗号。
