取而代之的是：
textView.setText(vnText);
编写此代码：
textView.setText(parent.getItemAtPosition(position).toString());
取而代之的是：
OnItemSelectedListener onItemSelectedListener =
new OnItemSelectedListener()
写这个：
OnItemSelectedListener onItemSelectedListener =
new AdapterView.OnItemSelectedListener()
同样取而代之的是：
@Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id)
传递每个微调器的相应适配器，而不是父级：例如，对于微调器，它应该是这样的：
@Override
public void onItemSelected(AdapterView<?> spinnerArrayAdapter1, View view,
int position, long id)
