The specific implementation code for getting the data in the form on the webpage in Android is as follows. If you are interested, refer to the following code. I hope to help you with MainActivity as follows:
The Code is 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 in the form on the webpage 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.
// In this way, Javascript can use this alias to call methods in Android.
// Window. testform. send (date + "|" + email + "|" + name + "|" + sex) in Javascript code );
// Send is the 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 ");
}
Private void initWebViewSettings (){
MWebView. setVerticalScrollBarEnabled (false );
MWebView. setHorizontalScrollBarEnabled (false );
MWebView. getSettings (). setJavaScriptEnabled (true );
MWebView. getSettings (). setsuppzoom zoom (true );
MWebView. getSettings (). setDomStorageEnabled (true );
MWebView. getSettings (). setPluginsEnabled (true );
MWebView. requestFocus ();
MWebView. getSettings (). setUseWideViewPort (true );
MWebView. getSettings (). setLoadWithOverviewMode (true );
MWebView. getSettings (). setsuppzoom zoom (true );
MWebView. getSettings (). setBuiltInZoomControls (true );
}
}
