    <p>Hi,</p> <p>I have created an app that uses ViewPager and all pages contain WebViews. Every Webview contains server images, videos, mp3 ...</p> <p>The WebView settings are </p> <pre><code> public Object instantiateItem(View collection, int position) { . . . final RelativeLayout imageLayout = (RelativeLayout) inflater.inflate(R.layout.omb_webview_layout, null); WebView webview = (WebView) imageLayout.findViewById(R.id.video_view); ProgressBar pbImage = (ProgressBar) imageLayout.findViewById(R.id.progressBar1); webview.requestFocus(View.FOCUS_DOWN); webview.getSettings().setBuiltInZoomControls(false); webview.getSettings().setSupportZoom(true); webview.getSettings().setUseWideViewPort(true); webview.getSettings().setJavaScriptEnabled(true); webview.getSettings().setLoadWithOverviewMode(true); webview.getSettings().setUseWideViewPort(true); webview.setWebViewClient(new mWebViewClient()); webview.getSettings().setPluginsEnabled(true); webview.clearCache(true); webview.clearHistory(); if(Pbar != null) { webview.setWebChromeClient(new WebChromeClient() { public void onProgressChanged(WebView view, int progress) { Log.i(TAG, "webview loading progress : "+ progress); if(progress == 100) { try { Pbar.setVisibility(ProgressBar.GONE); } catch (Exception e) { Log.e(TAG, "timer progress GONE : "+ progress,e); } } }); } </code></pre> <p>The problem is when pages are swiped then also this line </p> <pre><code> Log.i(TAG, "webview loading progress : "+ progress); </code></pre> <p>is executing which means that webviews are loading in background. If I swipe 4 or more pages all webviews are loading.</p> <pre><code> destroyItem(View collection, int position, Object o) { Log.d("DESTROY", "destroying view at position sheetal " + position); RelativeLayout view = (RelativeLayout)o; WebView tmp = webviewDictionary.get(position);; tmp.getSettings().setJavaScriptEnabled(false); tmp.stopLoading(); if(tmp != null){ Log.i(TAG, "sheetal webview is destroyed " +position ); try { tmp.onPause(); tmp.loadDataWithBaseURL("about:blank", "&lt;html&gt;&lt;/html&gt;","text/html", "UTF-8", null); tmp=null; // tmp.destroy(); } catch (Exception e) { Log.i(TAG, "webview destroyed Exception 0" ,e); } } </code></pre> <p>How to stop background loading if the pages are not visible? setOffscreenPageLimit(1)(means 3 page prev,cur,next),</p> <p>In Viewpager, 2 page (means 1 position page) is not loading properly. It shows a blank white page, how do I solve it?</p> <p>Thanks in advance </p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
