Question

• I have an xml layout file which contains a few widgets including a Spinner
• I want to display a list of strings in the spinner, the list is generated at runtime as a result of a function so it can not be in arrays.xml.

I tried doing:

String[] SpinnerItems = GetMyCustomItems();

((Spinner)findViewById(R.id.MySpinner)).setAdapter(new ArrayAdapter<String>(getBaseContext(), android.R.layout.simple_list_item_1,SpinnerItems));

But this crashes my application.

What would be the correct way to accomplish this?

Have a look at this example

It looks like you are missing a couple of things when implementing your Spinner and adapter

Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
        this, R.array.planets_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
