我将把它更新到 Android 平板电脑的 sqlite 数据库

boolean success = soDbHelper.updateAddressPhoto(orderid, fileHex);
                    Log.d("ADDRESS" , String.valueOf(success));


   public boolean updateAddressPhoto(String refno, String sign) {

            ContentValues args = new ContentValues();
            args.put(KEY_PHOTO_ADDRESS_HEX, sign);

            return mDb.update(DATABASE_TABLE, args, KEY_REFNO + "=" + refno, null) > 0;
        }

它没有显示任何异常，但显示为 false ，表示没有受影响的行

这是否意味着字符串太长？

Answer 1

我认为您应该尝试使用正确的更新查询语法，

像这样

db.update(表,值,COLUMN + "=?",args);

另一个建议是检查 HEX 的类型，可能它可能比它的列数据类型长。
