    <p>Once upon a time, life was simple: All web pages had finite length and if they didn't fit into the current windows/view size, you'd simply scroll down until you reached the bottom of the page.</p> <p>But I recently noticed that there is a new trend in the web design world: <strong>Bottomless</strong> web pages.</p> <p>Probably the most familiar examples of sites utilizing such pages are Facebook and Twitter: You scroll to the "bottom", only to trigger some refresh that adds content to the page, so the "old bottom" is no longer a bottom and, instead, there is a new "bottom".</p> <p>In an Android WebView, I need to be able capture all the content currently available on that "page", but I am not sure how to approach this:</p> <p>Simulate user's scroll down via <a href="https://stackoverflow.com/questions/5069765/android-webview-how-to-autoscroll-a-page/5070157#5070157">View.scrollBy(int x, int y)</a>, <a href="https://stackoverflow.com/questions/4680174/android-webview-scroll-down/4680975#4680975">pageDown()</a> or <a href="https://stackoverflow.com/questions/2238938/how-to-programmatically-scroll-android-webview/2239301#2239301">window.scrollTo()</a>?</p> <p>Or is there an API method that does this automatically for me?</p> <p>Or am I approaching this completely wrong and I shouldn't attempt to get to the "real bottom" in one capture (if possible at all)?</p> <p><strong>EDIT</strong>: It seems that tagging this question <code>javascript</code> communicated the opposite message. I am interested in capturing (then processing) such bottomless pages on Android's WebView, using <strong>Java</strong>.</p>

    1. COI'm not clear what "all the content currently available on that page" means in this context. If the page is "bottomless", doesn't that imply that there's a potentially infinite amount of content on that page? Or are you just wanting to trigger a certain number of these "load more content" events and then capture that?

    2. CO@Sean McMains Yes, I just want to trigger a certain number of these "load more content" events and then capture that. "Infinite" is only theoretical and/or figurative: A twitter (and Facebook) page can only go back so much in time.

    3. COBut that is the point isn't it. You could go on for any amount of time. If you want to get data from these services then use twitters API's to get somebodies entire history. This is not even a good idea. I would cap of "going further back" with a date or a set number of items.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
