Android :: Way To Find Height Of HTML Content Displayed In A Webview?

Apr 8, 2009

My application generates an HTML file which needs to be displayed to the user . For this purpose I'm using the loadData() API provided by Webview. This HTML file is updated every 2 secs & the same is loaded again using loadData() to display the updated values. On reloading the file the Webview starts displaying again from the top of the file causing the user to always scroll down to the location where he previously was. This causes a very bad user experience. To overcome this issue an alternative that I could think of was to split the file to multiple files that can exactly fit in the the screen. For this I need to find the height of the HTML content that can loaded in a web view. From the WebView documentation I found that an API getContentHeight() is provided for this purpose. Although this method returns me 0 on the first attempt. On subsequent attempt it gives me the height of the page that was previously loaded.

Android : WebView - Not Able To Go Back To My Activity Screen Once The Content Is Displayed

Apr 9, 2009

Step 1: I am subclassing WebView and rendering html content properly. The intial content is very small with a div and image /link This is displayed in a LInear Layout along with a TextView and ListView. That is my first screen/activity of the application.

Step 2: When I click on a link on this webview, it goes through the webViewclient and expands to full screen to fit the content of the requested page.

After Step 2, I am not able to go back to my activity screen once the content is displayed. When I click on the back button to getback to my activity screen close my activity and goes to the phone's applications desktop. (i.e goes out of my application).

Step 3: In order to fix this issue, I stopped setting my own subclasssed WebViewClient. After doing this, the it seems to render the clicked page in a webView as subactivity. Now When I click on backbutton, it goes back to the activity screen. But, the issue now is, I am not catch event when a link is clicked. How can I catch click events in this case.

Android : Change The Height Of A Webview On Runtime

Feb 26, 2010

I have a webview and a table containing 4 buttons. I have set the height of the webview to 400px, so that the buttons are displayed at the bottom of the screen, in portrait mode. My problem is, when changed to landscape mode the buttons are not visible. So I need to change the height of the webview on runtime, when orientation is changed. Do anybody know how to achieve this? I am able to capture the orientation change, using 'onConfigurationChanged' function.

Android : How To Display HTML Content?

Jan 23, 2009

I am working on an app where I would like to display HTML data to the user. The HTML includes CSS stylesheets and images (JPG and PNG), but no javascript and definitely no network access. The data is being read from a ZIP file on the sdcard. I initially assumed I could create a WebView and use that to display my HTML, but there seems to be no way to also pass in the style and image resources. Some posts I saw suggested creating a ContentProvider, but this has a few problems for me: a) security: I want to keep all the data inside this app. There's no need for a ContentProvider if I don't want other apps using the content, right? b) files: The ContentProvider's openFile() method returns a ParcelFileDescriptor, which can only be created from a Socket or a File. I have neither, I have an InputStream. So it seems there's no way to return the image and style data from a ContentProvider anyway.

Android :: Image Displayed At Webview From Url With High Quality Loss

Mar 17, 2010

I want to display an image from an url with an Webview at Android. With Android phones with Version 1.5 and 1.6 there is no problem. but the same pic and the same code on an AndroidPhone with Version 2.0 and the pic is totaly pixelated. Like Android is resizing the image first to a smaller one and then resizing it back to "normal" size. Unfortunately its important to display the pic without any quality loss. I tried to integrate it in the sourcefolder to show it as an normal image, but at Android 2.0 i get an exception because the image is to big. (At Android 1.6 there is no problem) Any ideas how i can display the image without quality loss with Android 2.0 ?

Android :: Way To Use Html In WebView To Build UI?

Nov 22, 2010

I've been building my app using the standard xml and Java Android layout libraries. I don't like the set up very much; and I would prefer to build the ui in html. I've been testing the speed of the WebView; and it seems that it is quite fast at rendering. Does anyone know if Google has ever said anything on the subject of building the ui in html and rendering it in a WebView? I know it's perfectly legal to render the UI in the WebView; but am I going to run into some problem in the future?

Android :: Way To Display HTML Markup In WebView?

Sep 13, 2010

I'm receiving XML which contains elements of HTML and I want to display these to the users. Therefore, I have to set the content programmatically, rather than extract the strings from an android xml resource. I'm using a WebView to display the content, rather than TextView, as it handles some of the HTML markup - bold text for example, and links. However WebView does appear to be rather limited.

Android :: Load HTML File To WebView With Custom CSS

Nov 6, 2010

I have a WebView on my Android application which loads (WebView.loadUrl()) different local HTML files from phone's internal storage. I would like to include some custom css styles for them, Now, I could have my app edit every HTML file and add linking reference for the CSS file.I could also read the file contents, add the CSS linking and use WebView.loadData() to load it.But is it possible to do this a lot simpler and efficiently.Note: The HTML files are downloaded from a website. So editing them manually is not possible in this case, but once downloaded they can be edited via the app if necessary.
