    <p>I've put a little app together that has three tabs to show three different web pages. It does work however I am bit worried I haven't got enough control over how this whole thing works. When I click a tab, I get a web page loaded (see code sample below), now when I click another tab another page loads in another view. When I go back to the first tab, the whole thing get initilized again and the page loads. Is there a way how I can control this and keep the underneeth tab's activity in its current state as long as I want (and say only "refresh" the page when it changes).</p> <p>do I need to handle onPause()/onResume() methods for that or instead implement my tabs as views of a single activity (is this possible at all?)? How do I store the state of my activity to avoid re-initializing it every time?</p> <p>this how activities are hooked to tabs:</p> <pre><code>intent = new Intent().setClass(this, tab_schedule.class); spec = tabHost.newTabSpec("Schedule").setIndicator("Schedule", res.getDrawable(R.drawable.tab_icon_schedule)).setContent( intent); tabHost.addTab(spec); </code></pre> <p>the tab_schedule.class does a simple web page load:</p> <pre><code>@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.tab_people); try { WebView currentView = (WebView) findViewById(R.id.tab_people_WebView); currentView.getSettings().setJavaScriptEnabled(true); currentView.loadUrl("http://pda.lenta.ru"); } catch (Exception e) { Log.v("webClientInit", e.getMessage()); } } </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.
