问题 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.
