这回应该明白了，那就上代码

package spinner_java;
    
    import org.apache.pivot.wtk.*;
    import org.apache.pivot.collections.*;
    
    public class spinner_java implements Application
    {
        
    	private Window window=null;
    	public static void main(String [] args)
    	{
        
    		try
    		{
        
    			DesktopApplicationContext.main(spinner_java.class, args);
    		}
    		catch(Throwable err)
    		{
        
    		}
    	}
    	@Override
    	public void startup(Display display, Map<String, String>properties)
    	{
        
    		window=new Window();
    		BoxPane panel=new BoxPane();
    		Spinner spinner1=new Spinner();
    		List<Integer> l=new ArrayList<Integer>();
    		//创建一个数组存放spinner的可选数字/字母
    		for(int doing=0;doing<100;doing++)
    		{
        
    			l.add(doing+1);
    		}
    		//将1到100添加到数组中
    		spinner1.setSpinnerData(l);
    		//设置Spinner数据
    		spinner1.setPreferredHeight(50);
    		spinner1.setPreferredWidth(100);
    		panel.add(spinner1);
    		PushButton button1=new PushButton();
    		button1.setButtonData("get spinner");
    		button1.getButtonPressListeners().add(new ButtonPressListener()
    				{
        
    			@Override
    			public void buttonPressed(Button button)
    			{
        
    				System.out.println(spinner1.getSelectedIndex());
    				System.out.println(spinner1.getSelectedItem());
    				System.out.println();
    			}
    				});
    		panel.add(button1);
    		panel.getStyles().put("padding", 10);
    		window.setContent(panel);
    		window.setTitle("Spinners");
    		window.setMaximized(true);
    		window.open(display);
    	}
    	@Override
    	public boolean shutdown(boolean optional)
    	{
        
    		if(window!=null)
    		{
        
    			window.close();
    		}
    		return false;
    	}
    	@Override
    	public void suspend()
    	{
        
    	}
    	@Override
    	public void resume()
    	{
        
    	}
    }
