Question

I am trying to populate a a spinner but I am getting an error with my String array saying “Array constants can only be used in initializers”. My code works fine when i employ the string array as a local variable, but as a global variable it doesn’t. I really need to be able to use my string array as a global variable. Thank you in advance. Here is my code:

 deleteselection = (Spinner)view.findViewById(R.id.deletespinner);
    ArrayAdapter<String> adapterdeletetype;
    //createdenominationsarray = getResources().getStringArray(R.array.createdenominations); //<--works
    //String [] createdenominationsarray = {"Select Portfolio", "Two", "Three"}; //<--works
    createdenominationsarray = {"Select Portfolio", "Two", "Three"};// <--doesn'twork
    adapterdeletetype = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,createdenominationsarray){
            @Override
            public View getDropDownView(int position, View convertView, ViewGroup parent)
            {
                View v = null;

                // If this is the initial dummy entry, make it hidden
                if (position == 0) {
                    TextView tv = new TextView(getContext());
                    tv.setHeight(0);
                    tv.setVisibility(View.GONE);
                    v = tv;
                }
                else {
                    // Pass convertView as null to prevent reuse of special case views
                    v = super.getDropDownView(position, null, parent);
                }

                // Hide scroll bar because it appears sometimes unnecessarily, this does not prevent scrolling 
                parent.setVerticalScrollBarEnabled(false);
                return v;
            }
        };      
    adapterdeletetype.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    denominationselection.setAdapter(adapterdeletetype);

I did the same thing for one of my project and it works for me. Below is the code snippet for your reference..

ArrayList<String> languages = new ArrayList<String>();
languages.add("English");
languages.add("German");
languages.add("French");
ArrayAdapter<String> langAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,languages);
ListView lv =(ListView)findViewById(R.id.listmain);
lv.setAdapter(langAdapter);
lv.setOnItemClickListener(new listclklisten(MainActivity.this));



public class listclklisten implements OnItemClickListener{
        private Context parent;
        public listclklisten(Context p){
            parent=p;
        }
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
            // TO DO your code here

        }
    }
