如果数据库是本地的，您应该添加读取权限（READ_EXTERNAL_STORAGE）；如果是互联网数据库，您将需要网络权限（"android.permission.INTERNET"）；此外，我建议您确保您连接到正确的网络并正确地 addressing the correct IP，因为通常当您遇到 "localhost 错误" 时，这意味着您在访问自己的 IP 地址。我只是提一下这个，以防这不是您希望从您的应用程序中获得的预期行为。另外，提供代码将会非常有帮助。
英文:
If the database is local, you should add Read permissions
(READ_EXTERNAL_STORAGE)
And if it's internet database, you'll need internet permissions
("android.permission.INTERNET")
Also, I'd suggest you to make sure you are on the correct network \ addressing the correct IP, seeing as you get "localhost error" usually means you are addressing your own IP address. Just mentioning this, in case that is not the desired behavior you want from your app.
Also, providing code will help a lot

本地主机地址在实际设备上无法运行。您需要使用IPv4地址和端口连接到数据库。
英文:
Localhost will not work on physical devices. You need to ipv4 and port to connect to the database.
