	private String[] mCounties={"beijing","guangdong","guangxi","hunan"};
	private List<String> allCounties=new ArrayList<String>();
	private String result="你选择的是：";
	
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.spinner);
		
		spinner1=(Spinner)findViewById(R.id.spinner1);
		spinner2=(Spinner)findViewById(R.id.spinner2);
		ok=(Button)findViewById(R.id.ok);
		
		for(int i=0;i<mCounties.length;i++){
			allCounties.add(mCounties[i]);
		}
		
		countiesAdapter=new ArrayAdapter<String>(SpinnerActivity.this,android.R.layout.simple_spinner_item,allCounties);
