这里介绍三种类型的颜色：列的背景色，单元格的背景色，单元格文本的颜色。

1.给ALV结构添加颜色控制字段：

三个字段都是同一类型：WDY_UIE_LIBRARY_ENUM_TYPE

COL_BACKG:列背景色

CELL_BACKG:单元格背景色

TEXT_BACKG:单元格文本背景色。

 

2.初始化ALV时，设置对应的字段和颜色控制

CASE ls_column-id.          WHEN 'POSTING_DATE'.            ls_column-r_column->set_cell_design( cl_wd_abstr_master_table_col=>e_cell_design-positive ).          WHEN 'OBJECT_ID'.            ls_column-r_column->set_cell_design_fieldname( 'CELL_BACKG' ).          WHEN 'STAT'.            DATA lr_cell_editor TYPE REF TO cl_salv_wd_uie.            DATA lr_text_view TYPE REF TO cl_salv_wd_uie_text_view.            lr_cell_editor = ls_column-r_column->get_cell_editor( ).            IF lr_cell_editor->editor = if_salv_wd_c_column_settings=>cell_editor_text_view.              lr_text_view ?= lr_cell_editor.              lr_text_view->set_semantic_color_fieldname( 'TEXT_BACKG' ).            ENDIF.          WHEN OTHERS.        ENDCASE.

日期列设置列背景色，单号设置单元格不同，状态列设置文本色。

 

3.查询数据时，控制颜色字段属性，设置颜色。

LOOP AT lt_retab INTO ls_retab.* 16 colors are available    l_cell_design = l_cell_design + 1.    IF l_cell_design > 17.      l_cell_design = 1.    ENDIF.* cell background color    CASE l_cell_design.      WHEN 1.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-standard.      WHEN 2.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-negative.      WHEN 3.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-positive.      WHEN 4.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-badvalue_dark.      WHEN 5.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-badvalue_medium.      WHEN 6.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-badvalue_light.      WHEN 7.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-criticalvalue_dark.      WHEN 8.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-criticalvalue_medium.      WHEN 9.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-criticalvalue_light.      WHEN 10.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-goodvalue_dark.      WHEN 11.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-goodvalue_medium.      WHEN 12.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-goodvalue_light.      WHEN 13.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-key_medium.      WHEN 14.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-group_level1.      WHEN 15.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-group_level2.      WHEN 16.        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-group_level3.    ENDCASE.* text colors    l_semantic_color = l_semantic_color + 1.    IF l_semantic_color > 7.      l_semantic_color = 1.    ENDIF.    CASE l_semantic_color.      WHEN 1.        ls_retab-text_backg = cl_wd_text_view=>e_semantic_color-standard.      WHEN 2.        ls_retab-text_backg = cl_wd_text_view=>e_semantic_color-diminished.      WHEN 3.        ls_retab-text_backg = cl_wd_text_view=>e_semantic_color-positive.      WHEN 4.        ls_retab-text_backg = cl_wd_text_view=>e_semantic_color-critical.      WHEN 5.        ls_retab-text_backg = cl_wd_text_view=>e_semantic_color-negative.      WHEN 6.        ls_retab-text_backg = cl_wd_text_view=>e_semantic_color-marked1.      WHEN 7.        ls_retab-text_backg = cl_wd_text_view=>e_semantic_color-marked2.    ENDCASE.    MODIFY lt_retab FROM ls_retab.  ENDLOOP.

好了，加颜色的代码已经完成，看看效果吧。
