一、 最简单的ALV显示
以前都是通过函数“REUSE_ALV_GRID_DISPLAY”来显示列表，这种方式是面向过程的，现在有另外一种面向对象化的方式来显示列表，函数REUSE_ALV_GRID_DISPLAY可以做到的它也能够做到。它主要是通过一个类CL_SALV_TABLE来实现的.
下面让我们来实现最简单的ALV列表。
1取得要显示的数据。
SELECT * INTO TABLE lt_tab FROM spfli
2.调用类CL_SALV_TABLE的静态方法Factory()创建类的实例。
TRY.
cl_salv_table=>factory(
IMPORTING
r_salv_table = lr_table
CHANGING
t_table = lt_tab
).
CATCH cx_salv_msg.
ENDTRY.
3.取得实例之后再调用方法Display（）显示列表.
lr_table->display( ).
处理过程完成，最后让我们看一下显示结果。

二、 ALV显示的三种形式
一般的ALV有三种显示形式，分别为
一、普通的List
二、全屏的Grid
三、在自定义屏幕的显示的Grid
跟以往实现这三种ALV显示方式相比，以往的三种显示方式分别是调用不同的Function和Class，实现方式复杂。现在这三种显示方式可以通过一个类(CL_SALV_TABLE)来实现，而且通过这个类和它的子类可以更加容易的实现ALV的功能，比如：排序，总计，过滤，页眉页脚，单击双击事件等。
下面让我们一步一步地来实现这三种显示形式。
1.首先我们先创建选择屏幕，屏幕有三个选项，三个选项分别为三种显示方式。
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取得要显示的数据。
SELECT * INTO TABLE lt_tab FROM spfli
3.判断选择屏幕的选项创建不同的实例。
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.当用户选择第一个选项，列表输出为全屏的网格列表，执行方法alv_full( )。
METHOD alv_full.
"创建实例
TRY.
cl_salv_table=>factory(
IMPORTING
r_salv_table = gr_table
CHANGING
t_table = lt_tab
).
CATCH cx_salv_msg.
ENDTRY.
"显示列表
gr_table->display( ).
ENDMETHOD. "alv_full
5.当用户选择第二个选项，列表输出为普通的列表，执行方法alv_list( ).alv_list方法跟alv_full方法不同的是在创建实例的时候多了一个选项list_display = ‘X’.
METHOD alv_list.
"创建实例
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.
"显示列表
gr_table->display( ).
ENDMETHOD. "alv_list
6.当用户选择第三个选项，列表在自定义屏幕上输出网格列表，执行方法alv_grid( ).方法alv_grid()调用了屏幕100。执行屏幕的时候会执行它的PBO和PAI，也就是会执行module status_0100和user_command_0100。Status_0100的代码是:
"定义变量

三、 ALV的功能设计
细心的读者肯定已经注意前面的两个例子少了点什么,少了ALV提供的标准功能,比如排序,过滤,汇总,等,以及用户可以在ALV的功能栏上加上自己自定义的功能按钮。
ALV的标准功能可以通过类CL_SALV_FUNCTIONS和CL_SALV_FUNCTION来设计,通过这两个类你可以对ALV提供的标准功能可见或不可见。也可以自己创建GUI STATUS设置自己的ALV功能，通过GUI STATUS来设置ALV的功能是通过类CL_SALV_TABLE的方法SET_SCREEN_STATUS来实现的。
1.首先我们要取得类CL_SALV_FUNCTIONS的实例，根据类CL_SALV_TABLE的方法get_functions可以取得功能实例。
lr_functions = gr_table->get_functions( ).
lr_functions->set_all( 'X' ).
2根据类CL_SALV_TABLE的方法设置功能栏。
gr_table->set_screen_status(
pfstatus = 'SALV_STANDARD'
report = sy-repid
set_functions = gr_table->c_functions_all ).
3.自定义功能的实现。ALV的自定义功能的实现动作要通过类的事件来处理。
Ø 首先定义事件的操作类
CLASS lcl_handle_events DEFINITION.
PUBLIC SECTION.
CLASS-METHODS: on_user_command FOR EVENT added_function OF cl_salv_events
IMPORTING e_salv_function.
ENDCLASS. "lcl_handle_events DEFINITION
Ø 实现事件的操作类
CLASS lcl_handle_events IMPLEMENTATION.
METHOD on_user_command.
DATA l_string TYPE string.
CONCATENATE 'Function is ' e_salv_function
INTO l_string
SEPARATED BY space.
MESSAGE i000(0k) WITH l_string.
ENDMETHOD. "on_user_command
ENDCLASS. "lcl_handle_events IMPLEMENTATION
Ø 注册事件
SET HANDLER lcl_handle_events=>on_user_command FOR lr_events.

lr_alv->main( ).
四、 ALV的显示样式
通过类CL_SALV_DISPLAY_SETTINGS我们可以设置ALV的显示样式，主要包括ALV表头名称，列表颜色间隔显示，水平线是否显示，竖线是否显示等。
1.首先我们要取得类CL_SALV_DISPLAY_SETTINGS的实例，根据类CL_SALV_TABLE的方法get_display_settings可以取得显示样式的实例。
lr_display = gr_table->get_display_settings( ).
2然后通过类CL_SALV_DISPLAY_SETTINGS的方法设置显示属性。
lr_display = gr_table->get_display_settings( ).
lr_display->set_striped_pattern( 'X' ). "设置颜色间隔显示
lr_display->set_list_header( 'Xin''s ALV' ). "设置ALV的抬头
lr_display->set_horizontal_lines( '' ). "设置水平线是否显示
lr_display->set_vertical_lines( '' ). "设置垂直线是否显示

五、 ALV的栏位属性
ALV的栏位属性是SAP提供的ALV功能的比较重要的一个，详细的功能包括异常状态图标、图标、符号、复选框、按钮、热点、超链接、单元格类型、单元格颜色、某一栏位颜色、某一行颜色，栏位隐藏等等。ALV的栏位功能主要是通过CL_SALV_COLUMN_TABLE和CL_SALV_COLUMNS_TABLE这两个类的实现的。
1. 首先我们要取得类CL_SALV_COLUMNS_TABLE的实例。
DATA lr_columns TYPE REF TO cl_salv_columns_table.
lr_columns = gr_table->get_columns( ).
2然后通过类CL_SALV_COLUMNS_TABLE的方法get_column(value)取得指定的栏位的CL_SALV_COLUMN_TABLE的实例，取指定的栏位的实例之后，你就可以对这个栏位的相关属性进行设置。
DATA lr_column TYPE REF TO cl_salv_column_table
lr_column ?= lr_columns->get_column( 'MANDT' ).
2. 取得指定的栏位的实例之后，在这个实例的基础上进行相关的属性设置。
a) 异常状态图标
lr_columns->set_exception_column( 'EXCEPTION' ).
lr_column ?= lr_columns->get_column( 'EXCEPTION' ).
lr_column->set_short_text( 'except' ).
b) 图标
lr_column ?= lr_columns->get_column( 'ICON' ).
lr_column->set_icon( 'X' ).
lr_column->set_long_text( 'ICON' ).
c) 符号
lr_column ?= lr_columns->get_column( 'SYMBOL' ).
lr_column->set_symbol( 'X' ).
lr_column->set_long_text( 'SYMBOL' ).
d) 复选框
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) 热点
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) 栏位不可见
lr_column ?= lr_columns->get_column( 'MANDT' ).
lr_column->set_visible( '' ).
g) 超链接[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( ).
LOOP AT gt_hyperlink INTO wa_hyperlink.
lr_hyperlinks->add_hyperlink(
handle = wa_hyperlink-handle
hyperlink = wa_hyperlink-hyperlink ).
ENDLOOP.
h) 栏位颜色
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) 行颜色和单元格颜色
lr_columns->set_color_column( 'T_COLOR' ).
j) 设置栏位显示长度最优化
lr_columns->set_optimize( 'X' ).
k) 设置标题栏是否可见
lr_columns->set_headers_visible( 'X' )
注：上面的所有栏位属性设置都要需要在相应的内表字段设置相关的值,设置是否可见除外。

六、 ALV的弹出窗口形式
前面的例子ALV列表都是直接输出在主窗口中，下面我们实现在弹出窗口中实现ALV。在弹出窗口中实现ALV也很简单，只要在实现类CL_SALV_TABLE的一个方法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的是弹出窗口的显示范围。

七、 ALV的选择功能
在ALV的输出结果中，要对它的某一行、某一列或者某一单元格进行选定，我们通常的做法是把鼠标直接点击那一行或者是列就可以了，如果选择多行或多列，在选择的条件按住‘CTRL’键就可以了。这是手动选择的方法，但是在实际情况中，有时候需要用程序来对输出结果进行选择。
首先我们要取得类CL_SALV_SELECTIONS的实例。
DATA lr_selections TYPE REF TO cl_salv_selections.
lr_selections = gr_table->get_selections( ).
2. 设置选择模式。
lr_selections->set_selection_mode( if_salv_c_selection_mode=>row_column ).
3. 选择行
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. 选择列
DATA lt_column TYPE salv_t_column.
APPEND 3 TO lt_row.
APPEND 4 TO lt_row.
lr_selections->set_selected_rows( lt_row ).
5. 选择一个单元格
DATA ls_cell TYPE salv_s_cell.
ls_cell-row = 7.
ls_cell-columnname = 'CITYFROM'.
lr_selections->set_current_cell( ls_cell )
6. 选择多个单元格
DATA lt_cell TYPE salv_t_cell,
ls_cell TYPE salv_s_cell.
ls_cell-row = 5.
ls_cell-columnname = 'CITYFROM'.
APPEND ls_cell TO lt_cell.
ls_cell-row = 6.
ls_cell-columnname = 'CITYFROM'.
APPEND ls_cell TO lt_cell.
lr_selections->set_selected_cells( lt_cell ).

八、 ALV的布局功能
在ALV的输出结果中，我们可以利用ALV提供的标准功能(过滤,排序,汇总)对输出结果正行操作。比如说我们对一个结果进行了排序和过滤等的动作，下次再运行这个报表的时候可以选择一个功能直接运行这些动作。这就需要布局（Layout）的功能了。
首先我们设置布局的功能按钮。
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. 设置前台选项页面。
SELECTION-SCREEN BEGIN OF BLOCK blk WITH FRAME.
PARAMETERS: p_lay LIKE disvariant-variant.
SELECTION-SCREEN SKIP.
PARAMETERS: p_save1 RADIOBUTTON GROUP rg DEFAULT 'X',
p_save2 RADIOBUTTON GROUP rg,
p_save3 RADIOBUTTON GROUP rg.
SELECTION-SCREEN END OF BLOCK blk.
3. 设置前台布局选项功能搜索帮助
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的一个类cl_salv_events_table提供了几个常用的事件，包括链接点击，双击，功能触发之前和触发之后，页眉页脚（其中页眉页脚暂时测试不成功，以后再试）。跟其他事件相比，类CL_SALV_EVENTS_TABLE提供了这几个常用的事件已经和ALV结合在一起，所以我们只要实现这几个事件的处理方法就可以了。
首先我们要定义好事件的处理方法。
CLASS-METHODS: on_user_command FOR EVENT added_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. 实现事件的处理方法。

ENDMETHOD. "on_after_salv_function
3. 取得ALV事件的实例
lr_events = gr_table->get_event( ).
4. 注册事件的处理方法
SET HANDLER lcl_handle_events=>on_user_command FOR lr_events.
SET HANDLER lcl_handle_events=>on_double_click FOR lr_events.
SET HANDLER lcl_handle_events=>on_link_click FOR lr_events.

十、 ALV的页眉页脚
除了可以通过类CL_SALV_EVENTS_TABLE的事件设置ALV的页眉页脚之外，还可以通过类CL_SALV_TABLE的方法SET_TOP_OF_LIST,SET_TOP_OF_LIST_PRINT,
SET_END_OF_LIST,SET_END_OF_LIST_PRINT这四个方法。页眉页脚的显示可以设置显示和打印时不一样，打印时的页眉页脚通过方法SET_TOP_OF_LIST_PRINT和SET_END_OF_LIST_PRINT。
声明设置页眉页脚所需要的Layout的实例和变量。
DATA: lr_grid TYPE REF TO cl_salv_form_layout_grid,
lr_grid2 TYPE REF TO cl_salv_form_layout_grid,
lr_text TYPE REF TO cl_salv_form_text,
lr_action TYPE REF TO cl_salv_form_action_info,
lr_header TYPE REF TO cl_salv_form_header_info,
lr_label TYPE REF TO cl_salv_form_label.
2. 添加页眉页脚所需要的文本到Layout里。
lr_header = lr_grid->create_header_information(
row = 1
column = 1
text = 'Header Information'
).
lr_label = lr_grid->create_label(
row = 2
column = 1
text = 'Label'
).
lr_action = lr_grid->create_action_information(
row = 3
column = 1
text = 'Action Information'
).
lr_text = lr_grid->create_text(
text = 'text'
row = 4
column = 1
).
gr_table->set_top_of_list( lr_grid ).
lr_text = lr_grid2->create_text(
text = 'end of page'
row = 1
column = 1
).
3. 使用方法SET_TOP_OF_LIST设置页眉
gr_table->set_top_of_list( lr_grid ).

十一、 ALV的聚合，排序，过滤
在ALV提供的标准工具栏上我们可以实现输出结果的聚合（最大值，最小值，汇总，平均数），排序，过滤功能，同样在程序里也可以达到这些功能。
声明聚合，排序，过滤所需要的变量。
DATA: lr_aggregations TYPE REF TO cl_salv_aggregations,
lr_filters TYPE REF TO cl_salv_filters,
lr_sorts type ref to cl_salv_sorts.
2. 汇总
lr_aggregations->add_aggregation(
columnname = 'DISTANCE'
aggregation = if_salv_c_aggregation=>total
).
3. 最小值
lr_aggregations->add_aggregation(
columnname = 'FLTIME'
aggregation = if_salv_c_aggregation=>minimum
).
4. 过滤
lr_filters->add_filter(
columnname = 'CITYFROM'
sign = 'I'
ption = 'NE'
low = 'ROM'
high = ''
).
5. 排序
lr_sorts->add_sort(
columnname = 'CITYFROM'
sequence = if_salv_c_sort=>sort_down
subtotal = 'X'
bligatory = 'X'
).
下面是效果图
