        adapter.setDropDownViewResource(R.layout.spinner_dropdown_item);
        spinner.setAdapter(adapter);

        spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                // Do whatever you want with your selected item. You can get it as: parent.getItemAtPosition(position); 
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {}
        });

        getActivity().getActionBar().setIcon(getResources().getDrawable(R.drawable.ic_launcher));//set your actionbar logo

Answer 1

In your onItemSelected(AdapterView parent, View view, int position, long id) set the view text to null with :

((TextView)view).setText(null);

Then set the icon you want via:

spinner.setBackgroundDrawable(/* your icon drawable*/);

Style up the xml of the Spinner element with heights and widths appropriate to your icon.
