    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        spnr = (Spinner)findViewById(R.id.spinner);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(
                this, android.R.layout.simple_spinner_item, celebrities);

        spnr.setAdapter(adapter);
        spnr.setOnItemSelectedListener(
                new AdapterView.OnItemSelectedListener() {

                    @Override
                    public void onItemSelected(AdapterView<?> arg0, View arg1,
                            int arg2, long arg3) {

                        int position = spnr.getSelectedItemPosition();
                        Toast.makeText(getApplicationContext(),"You have selected "+celebrities[+position],Toast.LENGTH_LONG).show();
                        // TODO Auto-generated method stub
                    }

                    @Override
                    public void onNothingSelected(AdapterView<?> arg0) {
                        // TODO Auto-generated method stub

                    }

                }
            );
    }

}

Spinner by default cannot work for Multiple selection.

If you need it, you have to extend it, check here
