SAP ALV自动刷新

通常我们需要对ALV的数据进行自动的刷新,来获取实时的数据,比如接口传来的数据,这时候后我们需要用到一个SAP为我们封装好的类,cl_gui_timer。

首先我们要声明
data:      timer    TYPE REF TO cl_gui_timer.
然后创建对象
  CREATE OBJECT timer.
指定调用的时间
  timer->interval = p_time.
但是值得注意的是,我们刷新后要重置下ok_code，需要使用触发事件来处理,在这里触发的是finished这个event

详细代码如下

1. *----------------------------------------------------------------------*
   
2. * CLASS lcl_receiver DEFINITION
   
3. *----------------------------------------------------------------------*
   
4. *
   
5. *----------------------------------------------------------------------*
   
6. CLASS lcl_receiver DEFINITION.
   
7.   PUBLIC SECTION.
   
8.     METHODS:
   
9.       handle_finished FOR EVENT finished OF cl_gui_timer.
   
10. ENDCLASS. "lcl_receiver DEFINITION
    
11. 
    
12. *----------------------------------------------------------------------*
    
13. * CLASS lcl_receiver IMPLEMENTATION
    
14. *----------------------------------------------------------------------*
    
15. *
    
16. *----------------------------------------------------------------------*
    
17. CLASS lcl_receiver IMPLEMENTATION.
    
18.   METHOD handle_finished.
    
19.     CALL METHOD cl_gui_cfw=>set_new_ok_code
    
20.       EXPORTING
    
21.         new_code = '&NTE'.
    
22. 
    
23.   ENDMETHOD. "handle_finished
    
24. ENDCLASS. "lcl_receiver IMPLEMENTATION
    
25. 
    
26. DATA: receiver TYPE REF TO lcl_receiver,
    
27.       timer    TYPE REF TO cl_gui_timer.
    
28. 
    
29. INITIALIZATION.
    
30.   CREATE OBJECT timer.
    
31.   CREATE OBJECT receiver.
    
32.   SET HANDLER receiver->handle_finished FOR timer.
