Mainactivity is as follows:
Copy Code code as follows:
Package cn.testjavascript;
Import Java.util.StringTokenizer;
Import Android.os.Bundle;
Import Android.webkit.WebView;
Import android.app.Activity;
/**
* Demo Description:
* Get the data from the form on the Web in Android
*/
public class Mainactivity extends activity {
Private WebView Mwebview;
Private String date =null;
Private String email = null;
Private String username = null;
Private String sex = null;
@Override
protected void OnCreate (Bundle savedinstancestate) {
Super.oncreate (savedinstancestate);
Setcontentview (R.layout.main);
Init ();
}
private void init () {
mwebview= (WebView) Findviewbyid (R.id.webview);
Initwebviewsettings ();
Mwebview.loadurl ("file:///android_asset/form.html");
Note the second parameter in the Addjavascriptinterface method
It represents the alias of our Java object Javaclass.
So that JavaScript can invoke the method in Android via this alias.
That is, in JavaScript code: Window.testform.send (date+ "|") +email+ "|" +name+ "|" +sex);
Send is a method name
Testform is an alias.
Mwebview.addjavascriptinterface (New Object () {
public void Send (String userInfo) {
StringTokenizer Userinfostringtokenizer = new StringTokenizer (userInfo, "|");
Date = Userinfostringtokenizer.nexttoken ();
email = Userinfostringtokenizer.nexttoken ();
Username = Userinfostringtokenizer.nexttoken ();
Sex = Userinfostringtokenizer.nexttoken ();
System.out.println ("userinfostringtokenizer=" +userinfostringtokenizer.tostring ());
System.out.println ("date=" + date);
System.out.println ("email=" + email);
System.out.println ("username=" + username);
System.out.println ("sex=" + Sex);
};
}, "Testform");
