试试这个

public class SpinnerActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Spinner spinner = (Spinner) findViewById(R.id.spinner1);
        List<String> list = new ArrayList<String>();
        list.add("list 1");
        ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,list);
        dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(dataAdapter);

        if (list.size() < 2) {
            spinner.setClickable(false);
            spinner.setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View v,MotionEvent event) {
                    if (event.getAction() == MotionEvent.ACTION_UP) {
                        Toast.makeText(SpinnerActivity.this,"Catch it!",Toast.LENGTH_SHORT).show();
                    }
                    return true;
                }
            });
        }
