This article mainly introduces the relevant knowledge of "how to use WebView". The editor shows you the operation process through an actual case. The operation method is simple, fast and practical. I hope this article "how to use WebView" can help you solve the problem.

WebView is a very important control in android, and its function is to display a web page.

(1) display and render web pages

(2) it can interact with page JavaScript to realize mixed development.

There are generally two forms of loading pages:

A: create a new local test.html file

Create steps:

A: create an assets folder

B: create the test.xml file under the generated assets folder

B: fill in WebView in the layout file of the project

Effect picture:

C: fill in the Java code

Run the effect diagram:

A: change the statement to load the local file to the following

Note:

If you directly use the above statement to load the web page, it is likely to pop up the system browser for web page access, so the use experience will be very poor! The solution is to add this line before loadUrl ():

Complete code:

WebView.setWebViewClient (new WebViewClient ())

WebView.setWebChromeClient (new WebChromeClient ())

WebView.setWebViewClient (new WebViewClient ())

Function: when you jump from one web page to another, we want the target web page to still be displayed in the current webview, rather than open in the browser / / if there is no webView.setWebViewClient (new WebViewClient ()); this sentence, the web page will be opened in the browser that comes with the phone.

WebView.setWebChromeClient (new WebChromeClient ())

Function: used to set richer processing effects, such as JS, progress bar, etc.
