WDA基础十六:ALV的颜色

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 + .
    IF l_cell_design > .
      l_cell_design = .
    ENDIF.
* cell background color
    CASE l_cell_design.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-standard.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-negative.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-positive.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-badvalue_dark.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-badvalue_medium.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-badvalue_light.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-criticalvalue_dark.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-criticalvalue_medium.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-criticalvalue_light.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-goodvalue_dark.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-goodvalue_medium.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-goodvalue_light.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-key_medium.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-group_level1.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-group_level2.
      WHEN .
        ls_retab-cell_backg = cl_wd_abstr_master_table_col=>e_cell_design-group_level3.
    ENDCASE.

* text colors
    l_semantic_color = l_semantic_color + .
    IF l_semantic_color > .
      l_semantic_color = .
    ENDIF.
    CASE l_semantic_color.
      WHEN .
        ls_retab-text_backg = cl_wd_text_view=>e_semantic_color-standard.
      WHEN .
        ls_retab-text_backg = cl_wd_text_view=>e_semantic_color-diminished.
      WHEN .
        ls_retab-text_backg = cl_wd_text_view=>e_semantic_color-positive.
      WHEN .
        ls_retab-text_backg = cl_wd_text_view=>e_semantic_color-critical.
      WHEN .
        ls_retab-text_backg = cl_wd_text_view=>e_semantic_color-negative.
      WHEN .
        ls_retab-text_backg = cl_wd_text_view=>e_semantic_color-marked1.
      WHEN .
        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。
