    <p>I have a viewflipper that contains a webview. In some cases (seemingly random) the bottom part of the webview will appear to jitter/jump. This can last anywhere between a second and several seconds. Here's a video to illustrate what I'm talking about <a href="http://www.youtube.com/watch?v=I8s2P4R95r4" rel="nofollow">http://www.youtube.com/watch?v=I8s2P4R95r4</a></p> <p>I've now created a basic test project that reproduces the problem <a href="http://dl.dropbox.com/u/1256312/WebView%20Test.rar" rel="nofollow">http://dl.dropbox.com/u/1256312/WebView%20Test.rar</a></p> <p>The problem only occurs in Honeycomb, and usually only in landscape mode. I've tested on several 2.x devices and everything's fine.</p> <p>After searching I found another case where someone had a similar problem in Honeycomb, but they suggested that the cause was markup related. However the markup I'm using is pretty basic and in any case I've extracted it and made sure that it was valid.</p> <p>Below is the relevant code. I've removed a lot things from the view to eliminate the problem being elsewhere. View1 has a viewflipper. In the activity I create a number of custom views of type View2 (which contains the offending webview) and add them to the viewflipper.</p> <p>View1 </p> <pre><code> &lt;LinearLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"&gt; &lt;ViewFlipper xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/question_flipper" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginLeft="50dp" android:layout_marginRight="50dp" android:layout_marginTop="50dp"&gt; &lt;/ViewFlipper&gt; &lt;RelativeLayout android:id="@+id/FormulaAndResultLayout" android:layout_width="fill_parent" android:layout_height="75dp" ..... etc. </code></pre> <p>View2</p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/QuestionLinearLayout" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" android:background="#123123"&gt; &lt;WebView android:id="@+id/question_web_view" android:layout_centerHorizontal="true" android:layout_below="@id/question_figure" android:layout_marginTop="5dp" android:layout_width="fill_parent" android:layout_height="wrap_content" android:scrollbars="none" android:layout_marginLeft="40dp" android:layout_marginRight="40dp" android:background="#444444"/&gt; &lt;/LinearLayout&gt; </code></pre> <p>Loading the webview</p> <pre><code>qWebView = (WebView) view.findViewById(R.id.question_web_view); qWebView.loadDataWithBaseURL(null, String.format(questionHTMLHeader, qObj.questionText), "text/html", "utf-8", null); </code></pre>

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.
