Recently, a lottery activity web page was nested in the Android project using WebView. The activity was online and running well (changed N requirements and sudden bugs). Fortunately, this mode of activity only needs to modify the web page without repackaging and publishing the market, which is also one of the advantages of this mode of development. Later, according to the feedback of the product brother, there is no progress prompt for loading the web page. Well, I really didn't think so much at that time. This needs to be added.. take it for granted that it's easy to handle it... In fact, it's easier than it Complicated

1. First, customize a WebView control

2. This control is introduced into the layout file that needs to use WebView

3. Add a drawable file and modify the progress bar style controlled by progress

4. Use the code associated with this control in an activity or fragment

Through the above code, the relevant functions of WebView to add Web page loading progress bar are realized. I hope it will be helpful to you.
