android/java 中两种延时执行的方法

// 消息处理方式实现延时
       new Handler().postDelayed(new Runnable()
       {
           public
void run()
           {
              myDialog.dismiss();
           }
       },3000);
 
       // 线程方式实现延时
       new Thread(new Runnable()
       {
           @Override
           public
void run()
           {
              try
              {
                  Thread.sleep(3000);
                  myDialog.dismiss();
              }
              catch (Exception
e)
              {
                 
e.printStackTrace();
              }
           }
       }).start();
