另一种解决方案......拥有单一textView并更新此textView的文本。

String textSelected = "Select from the drop down";



sp.setOnItemSelectedListener(new OnItemSelectedListener() {

    @Override
    public void onItemSelected(AdapterView<?> parent,
            View view, int pos, long id) {
        textSelected = parent.getItemAtPosition(pos).toString();
        textView.setText(textSelected);
    }

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

    }
});
