OO实现ALV
一、????? 最簡單的ALV顯示
以前都是通過函數(shù)“REUSE_ALV_GRID_DISPLAY”來顯示列表，這種方式是面向過程的，現(xiàn)在有另外一種面向?qū)ο蠡姆绞絹盹@示列表，函數(shù)REUSE_ALV_GRID_DISPLAY可以做到的它也能夠做到。它主要是通過一個類CL_SALV_TABLE來實現(xiàn)的.
下面讓我們來實現(xiàn)最簡單的ALV列表。
1取得要顯示的數(shù)據(jù)。
SELECT * INTO TABLE lt_tab FROM spfli
2.調(diào)用類CL_SALV_TABLE的靜態(tài)方法Factory()創(chuàng)建類的實例。
TRY.
???????cl_salv_table=>factory(
?????????IMPORTING
???????????r_salv_table = lr_table
?????????CHANGING
???????????t_table????? = lt_tab
??????? ).
????? CATCHcx_salv_msg.
??? ENDTRY.
?3.取得實例之后再調(diào)用方法Display（）顯示列表.
??????lr_table->display( ).
?處理過程完成，最后讓我們看一下顯示結(jié)果。

二、????? ALV顯示的三種形式
一般的ALV有三種顯示形式，分別為
一、普通的List
?二、全屏的Grid
?三、在自定義屏幕的顯示的Grid
跟以往實現(xiàn)這三種ALV顯示方式相比，以往的三種顯示方式分別是調(diào)用不同的Function和Class，實現(xiàn)方式復(fù)雜。現(xiàn)在這三種顯示方式可以通過一個類(CL_SALV_TABLE)來實現(xiàn)，而且通過這個類和它的子類可以更加容易的實現(xiàn)ALV的功能，比如：排序，總計，過濾，頁眉頁腳，單擊雙擊事件等。
下面讓我們一步一步地來實現(xiàn)這三種顯示形式。
1.首先我們先創(chuàng)建選擇屏幕，屏幕有三個選項，三個選項分別為三種顯示方式。
SELECTION-SCREEN BEGIN OF BLOCK blk WITH FRAME.
?PARAMETERS: p_full RADIOBUTTON GROUP rg,
?????????????p_list RADIOBUTTON GROUP rg,
?????????????p_grid RADIOBUTTON GROUP rg.
SELECTION-SCREEN END OF BLOCK blk.
2取得要顯示的數(shù)據(jù)。
SELECT * INTO TABLE lt_tab FROM spfli
3.判斷選擇屏幕的選項創(chuàng)建不同的實例。
?? CASE 'X'.
?????WHEN p_full.?????????????
???????me->alv_full( lt_tab ).
?????WHEN p_list.
???????me->alv_list( lt_tab ).
?????WHEN p_grid.
???????me->alv_grid( lt_tab ).
ENDCASE.
4.當(dāng)用戶選擇第一個選項，列表輸出為全屏的網(wǎng)格列表，執(zhí)行方法alv_full( )。
METHOD alv_full.
???"創(chuàng)建實例
??? TRY.
???????cl_salv_table=>factory(
?????????IMPORTING
???????????r_salv_table = gr_table
?????????CHANGING
???????????t_table????? = lt_tab
???????).
?????CATCH cx_salv_msg.
???ENDTRY.
?
???"顯示列表
???gr_table->display( ).
?ENDMETHOD.???????????????????"alv_full
5.當(dāng)用戶選擇第二個選項，列表輸出為普通的列表，執(zhí)行方法alv_list( ).alv_list方法跟alv_full方法不同的是在創(chuàng)建實例的時候多了一個選項list_display = ‘X’.
? METHOD alv_list.
???"創(chuàng)建實例
??? TRY.
???????cl_salv_table=>factory(
?????????EXPORTING
???????????list_display = 'X'
?????????IMPORTING
???????????r_salv_table = gr_table
?????????CHANGING
???????????t_table????? = lt_tab
??????? ).
?????CATCH cx_salv_msg.
???ENDTRY.
?
??? "顯示列表
???gr_table->display( ).
?ENDMETHOD.???????????????????"alv_list
6.當(dāng)用戶選擇第三個選項，列表在自定義屏幕上輸出網(wǎng)格列表，執(zhí)行方法alv_grid( ).方法alv_grid()調(diào)用了屏幕100。執(zhí)行屏幕的時候會執(zhí)行它的PBO和PAI，也就是會執(zhí)行module status_0100和user_command_0100。Status_0100的代碼是:

三、????? ALV的功能設(shè)計
細心的讀者肯定已經(jīng)注意前面的兩個例子少了點什么,少了ALV提供的標(biāo)準(zhǔn)功能,比如排序,過濾,匯總,等,以及用戶可以在ALV的功能欄上加上自己自定義的功能按鈕。
?ALV的標(biāo)準(zhǔn)功能可以通過類CL_SALV_FUNCTIONS和CL_SALV_FUNCTION來設(shè)計,通過這兩個類你可以對ALV提供的標(biāo)準(zhǔn)功能可見或不可見。也可以自己創(chuàng)建GUI STATUS設(shè)置自己的ALV功能，通過GUI STATUS來設(shè)置ALV的功能是通過類CL_SALV_TABLE的方法SET_SCREEN_STATUS來實現(xiàn)的。
1.首先我們要取得類CL_SALV_FUNCTIONS的實例，根據(jù)類CL_SALV_TABLE的方法get_functions可以取得功能實例。
lr_functions = gr_table->get_functions( ).
???lr_functions->set_all( 'X' ).
2根據(jù)類CL_SALV_TABLE的方法設(shè)置功能欄。
gr_table->set_screen_status(
???pfstatus????? =? 'SALV_STANDARD'
??? report??????? =?sy-repid
???set_functions = gr_table->c_functions_all ).
3.自定義功能的實現(xiàn)。ALV的自定義功能的實現(xiàn)動作要通過類的事件來處理。
????????首先定義事件的操作類
??? CLASSlcl_handle_events DEFINITION.
? PUBLICSECTION.
???CLASS-METHODS: on_user_command FOR EVENT added_function OF cl_salv_events
????????????????????? IMPORTINGe_salv_function.

四、????? ALV的顯示樣式
通過類CL_SALV_DISPLAY_SETTINGS我們可以設(shè)置ALV的顯示樣式，主要包括ALV表頭名稱，列表顏色間隔顯示，水平線是否顯示，豎線是否顯示等。
1.首先我們要取得類CL_SALV_DISPLAY_SETTINGS的實例，根據(jù)類CL_SALV_TABLE的方法get_display_settings可以取得顯示樣式的實例。
lr_display = gr_table->get_display_settings().
2然后通過類CL_SALV_DISPLAY_SETTINGS的方法設(shè)置顯示屬性。
lr_display = gr_table->get_display_settings().
???lr_display->set_striped_pattern( 'X' ). "設(shè)置顏色間隔顯示
???lr_display->set_list_header( 'Xin''s ALV' ). "設(shè)置ALV的抬頭
???lr_display->set_horizontal_lines( '' ).? "設(shè)置水平線是否顯示

五、????? ALV的欄位屬性
ALV的欄位屬性是SAP提供的ALV功能的比較重要的一個，詳細的功能包括異常狀態(tài)圖標(biāo)、圖標(biāo)、符號、復(fù)選框、按鈕、熱點、超鏈接、單元格類型、單元格顏色、某一欄位顏色、某一行顏色，欄位隱藏等等。ALV的欄位功能主要是通過CL_SALV_COLUMN_TABLE和CL_SALV_COLUMNS_TABLE這兩個類的實現(xiàn)的。
?1.?????首先我們要取得類CL_SALV_COLUMNS_TABLE的實例。
DATA? lr_columnsTYPE REF TO cl_salv_columns_table.
lr_columns = gr_table->get_columns( ).
2然后通過類CL_SALV_COLUMNS_TABLE的方法get_column(value)取得指定的欄位的CL_SALV_COLUMN_TABLE的實例，取指定的欄位的實例之后，你就可以對這個欄位的相關(guān)屬性進行設(shè)置。
DATA? lr_columnTYPE REF TO cl_salv_column_table
lr_column? ?= lr_columns->get_column('MANDT' ).
?2.?????取得指定的欄位的實例之后，在這個實例的基礎(chǔ)上進行相關(guān)的屬性設(shè)置。
a)???????? 異常狀態(tài)圖標(biāo)
lr_columns->set_exception_column('EXCEPTION' ).
?????? lr_column?= lr_columns->get_column( 'EXCEPTION' ).
lr_column->set_short_text( 'except' ).
b)????圖標(biāo)
lr_column ?= lr_columns->get_column( 'ICON').
??????lr_column->set_icon( 'X' ).
lr_column->set_long_text( 'ICON' ).
c)????符號
lr_column ?= lr_columns->get_column('SYMBOL' ).
??????lr_column->set_symbol( 'X' ).
lr_column->set_long_text( 'SYMBOL' ).
d)?????復(fù)選框
lr_column ?= lr_columns->get_column('CHECKBOX' ).
??????lr_column->set_cell_type( if_salv_c_cell_type=>checkbox ).
lr_column->set_long_text( 'CHECKBOX' ).
e)?????熱點
lr_column ?= lr_columns->get_column('HOTSPOT' ).
??????lr_column->set_cell_type( if_salv_c_cell_type=>hotspot ).
lr_column->set_long_text( 'HOTSPOT' ).
f)???欄位不可見
????? lr_column? ?=lr_columns->get_column( 'MANDT' ).
?? lr_column->set_visible( '' ).
g)? 超鏈接[likai1]?
lr_columns->set_hyperlink_entry_column('T_HYPERLINK' ).
???????lr_column ?= lr_columns->get_column( 'HYPERLINK' ).
???????lr_column->set_cell_type( if_salv_c_cell_type=>link ).
???????lr_column->set_long_text( 'HYPERLINK' ).
??????? lr_hyperlinks =lr_functional_settings->get_hyperlinks( ).
??????? LOOPAT gt_hyperlink INTO wa_hyperlink.
?????????lr_hyperlinks->add_hyperlink(
???????????handle??? = wa_hyperlink-handle
???????????hyperlink = wa_hyperlink-hyperlink ).
ENDLOOP.
h)??欄位顏色
lr_column ?= lr_columns->get_column('FLTIME' ).
???????ls_color-col = 6.
???????ls_color-int = 0.
???????ls_color-inv = 0.
?lr_column->set_color( ls_color ).
i)???行顏色和單元格顏色
lr_columns->set_color_column('T_COLOR' ).
j)?設(shè)置欄位顯示長度最優(yōu)化
lr_columns->set_optimize( 'X' ).
k)?設(shè)置標(biāo)題欄是否可見
lr_columns->set_headers_visible( 'X' )
?注：上面的所有欄位屬性設(shè)置都要需要在相應(yīng)的內(nèi)表字段設(shè)置相關(guān)的值,設(shè)置是否可見除外。

六、????? ALV的彈出窗口形式
前面的例子ALV列表都是直接輸出在主窗口中，下面我們實現(xiàn)在彈出窗口中實現(xiàn)ALV。在彈出窗口中實現(xiàn)ALV也很簡單，只要在實現(xiàn)類CL_SALV_TABLE的一個方法SET_SCREEN_POPUP就可以了。
gr_table->set_screen_popup(
????? start_column = 1
?????end_column?? = 120
?????start_line?? = 1
?????end_line???? = 20 ).
方法SET_SCREEN_POPUP的是彈出窗口的顯示范圍。

七、????? ALV的選擇功能
在ALV的輸出結(jié)果中，要對它的某一行、某一列或者某一單元格進行選定，我們通常的做法是把鼠標(biāo)直接點擊那一行或者是列就可以了，如果選擇多行或多列，在選擇的條件按住‘CTRL’鍵就可以了。這是手動選擇的方法，但是在實際情況中，有時候需要用程序來對輸出結(jié)果進行選擇。
?首先我們要取得類CL_SALV_SELECTIONS的實例。
DATA? lr_selectionsTYPE REF TO cl_salv_selections.
lr_selections = gr_table->get_selections( ).
2.??????設(shè)置選擇模式。
lr_selections->set_selection_mode(if_salv_c_selection_mode=>row_column ).
3.??????選擇行
DATA lt_row? TYPE salv_t_row.
APPEND 3 TO lt_row.
??? APPEND 4 TO lt_row.
lr_selections->set_selected_rows( lt_row ).
4.??????選擇列
DATA? lt_columnTYPE salv_t_column.
APPEND 3 TO lt_row.
??? APPEND 4 TO lt_row.
lr_selections->set_selected_rows( lt_row ).
5.??????選擇一個單元格
DATA? ls_cell TYPEsalv_s_cell.
ls_cell-row = 7.
??? ls_cell-columnname ='CITYFROM'.
lr_selections->set_current_cell( ls_cell )
6.??????選擇多個單元格

????????ls_cell? TYPE salv_s_cell.
ls_cell-row = 5.
??? ls_cell-columnname ='CITYFROM'.

八、????? ALV的布局功能
在ALV的輸出結(jié)果中，我們可以利用ALV提供的標(biāo)準(zhǔn)功能(過濾,排序,匯總)對輸出結(jié)果正行操作。比如說我們對一個結(jié)果進行了排序和過濾等的動作，下次再運行這個報表的時候可以選擇一個功能直接運行這些動作。這就需要布局（Layout）的功能了。
首先我們設(shè)置布局的功能按鈕。
ls_key-report = sy-repid.
??? lr_layout =gr_table->get_layout( ).
??? lr_layout->set_key(ls_key ).
???lr_layout->set_save_restriction( l_restrict ).
??? lr_layout->set_default('X' ).
??? IF p_lay IS NOT INITIAL.
?????lr_layout->set_initial_layout( p_lay ).
ENDIF.
2.??????設(shè)置前臺選項頁面。
SELECTION-SCREEN BEGIN OF BLOCK blk WITH FRAME.
PARAMETERS: p_lay LIKE disvariant-variant.
SELECTION-SCREEN SKIP.
PARAMETERS: p_save1 RADIOBUTTON GROUP rgDEFAULT 'X',
???????????p_save2 RADIOBUTTON GROUP rg,
???????????p_save3 RADIOBUTTON GROUP rg.
SELECTION-SCREEN END OF BLOCK blk.
3.??????設(shè)置前臺布局選項功能搜索幫助
DATA: ls_layout TYPE salv_s_layout_info,
??????????ls_key??? TYPE salv_s_layout_key,
??????????l_restrict TYPE salv_de_layout_restriction.
??? l_restrict = get_restrict().
??? ls_key-report = sy-repid.
??? ls_layout =cl_salv_layout_service=>f4_layouts(
??? s_key??? =ls_key
?? ?restrict = l_restrict ).
layout = ls_layout-layout.

九、?????ALV的事件
SAP的一個類cl_salv_events_table提供了幾個常用的事件，包括鏈接點擊，雙擊，功能觸發(fā)之前和觸發(fā)之后，頁眉頁腳（其中頁眉頁腳暫時測試不成功，以后再試）。跟其他事件相比，類CL_SALV_EVENTS_TABLE提供了這幾個常用的事件已經(jīng)和ALV結(jié)合在一起，所以我們只要實現(xiàn)這幾個事件的處理方法就可以了。
?首先我們要定義好事件的處理方法。
CLASS-METHODS: on_user_command FOR EVENTadded_function OF cl_salv_events_table
?????????????????????IMPORTING e_salv_function,
??????????????????on_double_click FOR EVENT double_click OF cl_salv_events_table
??????????????????????IMPORTING row column,
??????????????????on_link_click?? FOR EVENT link_click OF cl_salv_events_table
??????????????????????IMPORTING row column,
??????????????????on_before_salv_function FOR EVENT before_salv_function OF cl_salv_events_table
??????????????????????IMPORTING e_salv_function,
??????????????????on_after_salv_function FOR EVENT after_salv_function OF cl_salv_events_table
??????????????????????IMPORTING e_salv_function.
2.??????實現(xiàn)事件的處理方法。
*單擊新增功能按鈕事件處理方法

???????????????e_salv_function
??????????INTO g_string SEPARATED BY space.
???MESSAGE i000(0k) WITH g_string.
?ENDMETHOD.???????????????????"on_after_salv_function
3.??????取得ALV事件的實例
lr_events = gr_table->get_event( ).
4.??????注冊事件的處理方法
SET HANDLER lcl_handle_events=>on_user_commandFOR lr_events.
??? SET HANDLERlcl_handle_events=>on_double_click FOR lr_events.
??? SET HANDLERlcl_handle_events=>on_link_click FOR lr_events.
??? SET HANDLERlcl_handle_events=>on_before_salv_function FOR lr_events.
??? SET HANDLER lcl_handle_events=>on_after_salv_functionFOR lr_events.
