setContentView() is not enough to switch between layouts?
===

I have 2 layouts. 

The 1st loads (a WebView) fine when the program starts. 

The 2nd one also loads (a simple layout) fine when user selects a menu item:

    setContentView(R.layout.simple);
    LinearLayout ll = (LinearLayout) findViewById(R.id.simple_layout);

All it does is display an image while processing something in the background. When processing is done, it attempts to switch back (via Handler) to the WebView it just obscured.

    setContentView(R.layout.main);

The switching seems to occur but the webview is **blank**.

Why is that? Isn't `setContentView()` enough to switch back to the 1st layout just as the switch to 2nd worked fine?
