Use of html, js, and css in combination with Android

The following example shows how to share your experience with a friend on the Internet. I posted this article, so you should pay more attention and make fewer mistakes.

Important:

Key code in android:

Webview. getSettings (). setJavaScriptEnabled (true );

Webview. addJavascriptInterface (object, "name"); // Add the object Name = "name" to the object. If the object is this, It is window. name.

Webview. loadUrl ("file: // android_asset/index.html"); // note that the resource is located in the same folder as res.

Call the method code in android in js or html:

For example:

Or the method () in window. name. java in js ();

The function Method of calling js in android:

Callfunction (){

Webview. loadUrl ("javascript: function ()");

}

 

Note that many data types are not recognized in js. It is best to encapsulate them in android to provide necessary method interfaces. For example, if you upload the list to js, you cannot obtain the elements in js.

In fact, the above are all nonsense:

Important: The following two connections
