    <p>I have an activity that stores 5 <code>WebViews</code> in a <code>ViewFlipper</code>. It only shows one at a time. In the onCreate() of my activity I'm loading the first WebView on my main thread and the others in a background thread.</p> <p>What I was expecting was to see the <code>WebView</code> right away while the others were still loading. What I found is that the first <code>WebView</code> i perform a <code>loadData()</code> with finishes last. I found this by setting a <code>WebChromClient</code> and checking the <code>onProgressChanged()</code>. The first WebView always seems to load last. </p> <p>I'm assuming the WebView.loadData() function works asynchronously, but I have no idea why the first one I load always finishes last, not ever 2nd, 3rd, 4th or 1st, but 5th, which is last in my case.</p> <p>Does anyone know why?</p> <p>Here's some example code:</p> <p>Setting up my WebViews</p> <pre><code>for( int i = 0; i &lt; 5; i++ ){ WebView tempWebView = new WebView(this); tempWebView.setWebChromeClient( new MyWebChromClient( i ) ); mFlipper.addView(tempWebView); } ( (WebView)mFlipper.getChildAt(0) ).loadData( content, "text/html", "UTF-8" ); // load the others now in a background thread... </code></pre> <p>Here's my WebChromClient</p> <pre><code>private class MyWebChromClient extends WebChromeClient{ private int webViewId; public MyWebChromClient( int viewFlipperChildNum ){ webViewId = viewFlipperChildNum; } public void onProgressChanged(WebView view, int newProgress) { if( newProgress == 100 ) Log.i("ChromClient", "WebView Id: " + webViewId + "Progress changed: " + newProgress ); }; } </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.
