Android Spinner dynamically change items

Question

I want to use a Spinner in my App. The context (items) of the Spinner are depending on the user preferences done in the Settings of the App.

I created the Spinner with no items. After loading the App the Spinner has one Entry. To get the Entries the User has to go to the menu and load an image. Based on this the items are loaded into a String Array. This String Array will be hand over to a Adapter. See Code:

List<String> als = new ArrayList<String>();
als = Arrays.asList(Data.getfloornames());
adapter = new ArrayAdapter<String>(this, R.array.flooritem, als);
adapter.notifyDataSetChanged();
floornum.setAdapter(adapter);

After this is done. The user will be returned to the menu settings. Clicking in the menu Settings the return button of the devices, result an abort of the app.

Error from Logcat is FATAL Exception: main.

What am I doing wrong? Is it not possible to set the Spinner Items in the menu settings of the app?

Try to change this :

adapter.notifyDataSetChanged();
floornum.setAdapter(adapter);

into this :

floornum.setAdapter(adapter);
adapter.notifyDataSetChanged();

See ArrayAdapter javadoc.

textViewResourceId The resource ID for a layout file containing a TextView to use when instantiating views.

The Spinner has no textView. I use the array Entries in String.xml as Ressource. I also tried to use the layout id and the id of the Spinner. Result is always the same. – Irgendw Pointer May 16 '13 at 13:53
yes it has, change R.array.flooritem to android.R.layout.simple_spinner_item and see the difference – pskink May 16 '13 at 14:37
Oh sorry just saw your answer now. It is solved with the answer from sandeep. – Irgendw Pointer May 17 '13 at 06:19
