when i try to get the html source code from webview i use this example for my solution:
Extracting HTML from a WebView
now i want to parse a page which has no html content. the page displays only a text extracted from xml source.
does anybody have an idea how to get the content (or xml source code) from webview?
best regards
EXAMPLE: XML
< ID >test< /ID > <BR>
< Status >0< /Status >
Is shown as: test0 in webview
I want get the "test0" and put it to string
Option #1: Use the same approach as is shown in the linked-to blog post. Devise some JavaScript that grabs the data out of your Web page and call that JavaScript via loadUrl(), routing the results to some JavaScript interface you injected into the WebView via addJavascriptInterface().
Option #2: Don't use WebView at all, and use HttpURLConnection or HttpClient to fetch the XML source.

I have the URL of a webpage to be displayed into a webview in my Android app. Before showing this page i want to clear the html code of this page from some tag (such as the header, footer, ecc..) in order to show only few information. How can i do it? I tried to solve the issue working with JSoup but i can't understand how to create and pass the "new page" to the webview. Anybody can help me?
EDIT
I cleaned the html code useless through jsoup libraries. Then, always by mean of these, i get head and body content and finally i showing the "cleared" web page through these lines:
headURL = doc.select("head").outerHtml();
bodyURL = doc.select("body").outerHtml();
webview.loadData( "<html>"+headURL+bodyURL+"</html>" , "text/html", "charset=UTF-8");
webview.setWebViewClient(new DisPlayWebPageActivityClient());
The view shows the new page but do not load css files specified in the head(that has not been touched). Who can say me why?
You can fetch the WebPage you want to display as a string, parse and remove whatever you don't want and then load this string as data in your webview.
Something like:
String webContent = fetchPage(url);
String cleanedWebContent = cleanUp(webContent);
webView.loadData(cleanedWebContent, "text/html", "UTF-8");
Of course, you will need to implement fetchPage and cleanUp as they are not Android methods
When I try to reload the titanium webview true webview.reload(), the view does not reload correctly. Instead if loading the page it gives me a page not found.
what i'm doing:
In Titanium i make use of webviews to display data. These webviews make use of HTML that is stored in the local filesystem that Titanium offers. The webview is called url is set by :
webview.setUrl( Ti.Filesystem.applicationDataDirectory.toString() + 'index.html');
This sets the proper url for the webview, it let's me see the correct html page. When I use webview.reload(), it seems lost... is there a way to reload the webview, or should i remove and then add the webview again?
Setting a URL for WebView the resource is usually loaded from the Resources folder.
So try to move all HTML files there (into Resources, same folder where app.js is located) and simply use.
webview.setUrl('index.html');
This has worked for me both on iOS and Android.
(There is an issue related to Android regarding WebView and setting its content by html property but this shouldn't matter here)
In my app,I have link http://mymobilece.com/api/api_getexammaterials.php?id=28,
I want to view in webview ,I try with google document viewer its work fine But i need it without google document viewer,How to show it??
you can use the js for google Doc viever
myScript="<html><iframe src='http://docs.google.com/gview?
url='http://mymobilece.com/api/api_getexammaterials.php?
id=28'&embedded='true' style='width:600px; height:500px;'
frameborder='0'></iframe></html>"
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadData(myscript,"text/html", "UTF-8");
you can use myscript as string variable and use this javascript code(please make sure to remove double quite if above code) and load in webview
You can change the url - width- height variables according to your scripting.
Docs.google.com has a document parser , which basically parses MS-Office files , thats why you can view it on google docs. without that you will have to write document parser. Which will parse files and fetch the contents to display on view. In Short it will be not a good idea to do that. :)
I take the response from an HTTP connection in the form of string and show that to webview like this:
WebView engine = (WebView)findViewById(R.id.webview);
engine.loadData(endResult, "text/html", "UTF-8"); /*endresult is string*/
I actually get a response that contains the google page (google search result direct from google.com).
The loadData method works well i.e it shows the web page but when I click on one of the links on that page it shows "page not available" and said that "xyz link might be temporarily down or it may have moved to permanently to a new web address".
this happens for all links accept the first present link on that page. i.e it shows correct page from first link on that page but fails for others..
I noticed that OSes prior to 2.3 failed to follow links if setHorizontalScrollBarEnabled and setVerticalScrollBarEnabled are set to false.
try to use loadDataWithBaseURL of the WebView class
I would avoid using engine.loadData - it seems to cause all sorts of crazy problems.
Use engine.loadDataWithBaseURL instead, and pass the base URL of where the content exists. I would think that the content you are loading is using relative paths in it's HTML so it's looking inside your app resources. By specifying the base URL you get around this problem.

In my application i need to display a html page in webview and that html page should refer to sdcard location for .css file (Using link href="...." tag).
I placed 2 files (i.e) html and css ) in sdcard->mibook.
I tried by giving absolute path as link href="/mnt/sdcard/mibook/0.css"
how can i specify path name android?
Edited:
Above problem solved : by using this- link href="file:///sdcard/mibook/0.css"
But i have following requirement,
i need to handle around 50+ html file every time ,
I placed all files as follows,
mibook->book1->pg90.sqlite
mibook->book1->links->o.css and 1.css
The sqlite file contains html pages. each html page has css reference as link href="/links/0.css"
These css file should be refer by html. how can i do this?
Try

Assuming Android >= 2.1
