Seems so simple...create a textview, prior to adding the arrayAdapter, apply the header as myListVew.addHeader(t); then (or before) set the text for the TextView (t) with t.setText(aString). (I believe the actual variable's name was flashCurrentMode).
Here's basically what I did (I originally deleted the code when it failed...not good, so I'm recreating it in more generic code). Textview t; // defined globally Later, while setting up the ListViews t = new TextView(this); String s = parameters.getFlashMode(); // Log.i verifies that s != null t.setText(s); mbigListView.addHeader(t); // attach to array adapter here That works. The first time I make that ListView visible, it has a header showing the current flash mode, which is exactly what I wanted it to do. The problem comes when I CHANGE the flash mode, and, from within the onItemClick for mbigListView, do (almost) the same as earlier: First, to set s, I tried both of the following (after setting the new parameters): String s = parameters.getFlashMode(); String s = flashModes(idx); Either way, Log.i confirms, s is "torch" (the new flash mode). Then, continuing with setting the new header, t.setText(s); // THIS causes a Null Pointer Exception//Force Close mbigListView.addHeader(t); // we never get this far Why would setting the text of the TextView the second time cause a force close (caused by a null pointer exception, where the string being assigned was not null)? I know I'm missing something...but what? It seems amazingly simple, but something obviously isn't as simple as it appears from the dev guide.
