	private Button ok;
	private ArrayAdapter countiesAdapter;
	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);
		countiesAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

		//单击第一个下拉按钮时，显示选择的值。 
		spinner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
			@Override
			public void onItemSelected(AdapterView<?> adapter, View view,
					int position, long id) {
				// TODO Auto-generated method stub
				String str=(String)spinner1.getAdapter().getItem((int)id);
				setTitle(result+str);
			}

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