[android-developers] Re: WebView loadData and XML Parsing Question

2009-02-19 Thread forandroid 

I have to display html content which i get from am xml(RSS feed).I am
using the loadDataWithBaseURL .

But if the the html content contains an image,how do i render the
image in the webview as in the html content.


webView.loadDataWithBaseURL(www.company.com,descHtmlString, text/
html, utf-8, www.companyfailed.com);

 no change there.

 I'm guessing it's the loadDataWithBaseURL function that did the trick,
 but I will try both suggestions in isolation just to make sure.

 I'd rather not use the loadDataWithBaseURL to load local data if I can
 help it, so I'll continue researching a fix for the loadData function.

 Thanks for your help.

I am trying to show a html string such as

sample3 =a href=\www.google.com\Link text/aimg src=
http://www.isical.ac.in/~clia/images/google_logo.jpg;

webView.loadDataWithBaseURL(www.company.com,sample3 , text/html,

2009-01-12 Thread Ryan 

Thanks for your reply Fred. The debug log shows the follwing line for
getting the text out with the xpp.next() function.

01-12 21:53:48.705: INFO/System.out(549): Text BRBTonight's

BRProbability of rain: 89%BRMinimum Temperature: 6C(43F )BRWind

The log then shows:-

01-12 21:53:49.544: INFO/ActivityManager(51): Displayed activity
com.mycom.myapp/.MyWebViewActivity: 5050 ms

It is this activity that has a WebView that calls the loadData
function with the string above.

There are no errors as such. It's as if the WebView takes the string
as a URL and try's to request data from the URL, instead of just
displaying the string. Does that make sense?

[android-developers] Re: WebView loadData and XML Parsing Question

2009-01-12 Thread Ryan 

Actually, I think I am confusing the issue. I just tried the following
code inside my WebView:-

final String mimeType = text/html;
final String encoding = utf-8;
html = BRBTonight's weather in London/BBRA few evening
showers Min 6C(43F )BRProbability of rain: 89%BRMinimum
Temperature: 6C(43F )BRWind force Beaufort: 4BRWind description:
Moderate BreezeBRWind direction: SSWBRSunset at: 4:17 pm;
this.loadData(html, mimeType, encoding);


This does not do wha I expect. This displays a WebView with the
following error message:-

Web page not available
The Web page at data:text/html;utf-8...
might be temporarily down..

I was expecting the WebView to use my string as the HTML content. This
is how it works for simpler strings.

Try loadDataWithBaseURL(), even if you have to supply a garbage URL as
the base (e.g., fake://oh.this.is.so.not.real).

Also, try UTF-8 instead of utf-8.

Also also, the html variable is a String, and not something else, right?
