我正在尝试将位图存储为 BLOB 和一些字符串在同一个 SQLdatase 中。

这是我的数据库：

// 更新单个联系人

public int update(String name, String email, String uid, String tel, String niver, String created_at, byte[] thumb) {
    SQLiteDatabase db = this.getWritableDatabase();

    ContentValues values = new ContentValues();
    values.put(KEY_NAME, name); // Name
    values.put(KEY_EMAIL, email); // Email
    values.put(KEY_UID, uid); // Email
    values.put(KEY_TEL, tel); // Telefone
    values.put(KEY_NIVER, niver); // Niver
    values.put(KEY_CREATED_AT, created_at); // Created At
    values.put(KEY_THUMB, thumb); // thumb

    //db.close(); // I deleted this line

    // updating row
    return db.update(TABLE_LOGIN, values, KEY_THUMB + " = ?",
            new String[] { String.valueOf(getRowCount()) });
}

我用它来用位图更新数据库；

                    imagebutton.setImageBitmap(photo);
                    imagebutton.setScaleType(ScaleType.FIT_XY);
                    ByteArrayOutputStream stream = new ByteArrayOutputStream();
                    photo.compress(Bitmap.CompressFormat.JPEG, 100, stream);
                    byte[] imageInByte = stream.toByteArray();
                    db.update(null, null, null, null, null, null, imageInByte);

使用此代码，它现在可以工作：

 public int updateUser(byte[] thumb) {
        SQLiteDatabase db = this.getWritableDatabase();
        ContentValues values = new ContentValues();
        values.put(KEY_THUMB, thumb); // thumb
        Log.w(TAG, String.valueOf(thumb));
        // updating row
        return db.update(TABLE_LOGIN, values, null,
                null );
    }

new String[] { String.valueOf(getRowCount()) } 在 logcat 上给了我这个错误。
