java和android中子线程更新主线程界面

1，android中用Handler
2，java中界面是用swt写的，所以用

public void actionPerformed(ActionEvent e){   
         new Thread(new Runnable(){   
                  //do something    
                  SwingUtilities.invokeLater(new Runnable(){    
                      public void run(){    
                      //update the GUI   
                    }   
               });    
  
      }).start;    
 }
