你只需要打电话：

public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

    String item = parent.getItemAtPosition(position).toString();

    Toast.makeText(parent.getContext(), "Selected: " + item, Toast.LENGTH_LONG).show();
    Intent i = new Intent(Intent.ACTION_VIEW);
    i.setData(Uri.parse("www."+item+".com"));
    startActivity(i);
}

public void onNothingSelected(AdapterView<?> arg0) 
{}
