How to display stub in webview?

Question

Android

How to show a picture from a local resource instead of a standard error in a webView?
In the process of using the application, for example, the Internet disappears. It is necessary to replace the standard error screen with a picture of some kind of conditional, for example, that something went wrong for the user.
(for example, the connection was lost)
How to implement this, if possible, then code examples. The finished solution is perfect.
