单向页面跳转可以直接使用intent，如：

Intent intent=new Intent();

intent.setClass(MainActivity.this , SecondActivity.class);

MainActivity.this.startActivity(intent);

如果是类似的启动页的跳转，则需要一种可以返回的双向页面跳转

final static int REQUEST=10;

Intent intent=new Intent(MainActivity.this , SecondActivity.class);

startActivityForResult(intent,REQUEST);

protected void onActivityResult(int requestCode , int resultCode , Intent data){

    if(requestCode==REQUEST){   //第二个页面返回的数据

        if(resultCode==RESULT_OK){    // 区分结果是否属于正常返回

        System.out.println(“操作成功”);

        }else if(resultCode==RESULT_CANCELED){

         System.out.println(“操作失败”);   

        }

    }

}

第二个页面的代码

（也可在此处添加计时器等操作，如：Handler handler=new handler();

                                                          handler.postDalayed( new Thread(){

                                                           

                                                         public void run(){                                                  

                                                            Intent intent=getIntent();

                                                            setResult(RESULT_OK , intent);     //设置返回结果成功

                                                            finish();    // 关闭当前页面

                                                    }        },3000  );    }

)

Intent intent=getIntent();

setResult(RESULT_OK , intent);     //设置返回结果成功

finish();    // 关闭当前页面

备注：intent的跳转方式仅在activity中实现，serverce等的服务不可以进行跳转
