Android embedded web page webview click the link to jump to the Activity in our application

In a large Android project, because the client is too late to be updated and implemented, some web pages are often embedded (in some large Internet companies, PC products always run in front of the client ), for example, an activity page can usually be embedded with HTML 5 to adapt to mobile phones. However, these webpages have many links, but some of these links are implemented by our client. For example, if there is a registration link, the client also implements the registration function, instead of continuing to jump to the webpage registration page, we open a client to register an Activity. You can achieve this by using the following methods:

 

Xml file, as follows:

 

The java code is as follows:
