Question

Any ideas why this code throws a NullPointException?

    Spinner spinnerLoadLayouts = (Spinner)this.findViewById(R.id.spnLoadLay);

    ArrayAdapter<CharSequence> adapter = 
    new ArrayAdapter<CharSequence>(this, android.R.layout.simple_spinner_item, new ArrayList<CharSequence>());

    adapter.add("aaa"); adapter.add("bbb");
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinnerLoadLayouts.setAdapter(adapter);

Thanks! 🙂

Answer 1

I guess that the View or Activity cannot find R.id.spnLoadLay
