3、在上面caller_exit定义的FORM.:'FM_BUTTON'里通过函数‘GET_GLOBALS_FROM_SLVC_FULLSCR’得到ALV的GRID对象,再设置这个GRID的BUTTON_CLICK事件。

    DATAGV_GRIDTYPEREFTOCL_GUI_ALV_GRID.

    FORMFM_BUTTONUSINGE_GRIDTYPESLIS_DATA_CALLER_EXIT.

    CALLFUNCTION'GET_GLOBALS_FROM_SLVC_FULLSCR'

    *EXPORTING

    *IR_SALV_FULLSCREEN_ADAPTER=

    IMPORTING

    *ET_EXCLUDING=

    *E_REPID=

    *E_CALLBACK_PROGRAM=

    *E_CALLBACK_ROUTINE=

    E_GRID=GV_GRID

    *ET_FIELDCAT_LVC=

    *ER_TRACE=

    *E_FLG_NO_HTML=

    *ES_LAYOUT_KKBLO=

    *ES_SEL_HIDE=

    *ET_EVENT_EXIT=

    *ER_FORM_TOL=

    *ER_FORM_EOL=

    .

    CREATEOBJECTGV_EVENT_RECEIVER.

    SETHANDLERGV_EVENT_RECEIVER->HANDLE_BUTTON_CLICKFORGV_GRID.

    ENDFORM.

    4、在CLASS中定义的BUTTON_CLICK事件的FORM：BUTTON_CLICK中写需要单击按钮后完成的处理。

    FORMBUTTON_CLICKUSINGP_COL_ID

    P_ROW_NOTYPElvc_s_roid.

    READTABLEITAB_ALVDATAINTOWA_ALVDATAINDEXP_ROW_NO-ROW_ID.

    PERFORMFM_DISPLAY_COMMENT.

    ENDFORM.

    5、DISPLAYALV

    PERFORMFM_EVENT_BUILD.

    *CallALVFuncation

    CALLFUNCTION'REUSE_ALV_GRID_DISPLAY_LVC'

    EXPORTING

    I_CALLBACK_PROGRAM=SY-REPID

    I_GRID_TITLE=GV_TITLE

    I_DEFAULT='X'

    I_SAVE='A'

    IT_EVENTS=GV_EVENTS

    IT_FIELDCAT_LVC=GV_FIELDCAT_ALV[]

    IS_LAYOUT_LVC=GV_LAYOUT

    I_CALLBACK_PF_STATUS_SET=GV_STATUS

    I_CALLBACK_USER_COMMAND='USER_COMMAND'

    TABLES

    T_OUTTAB=ITAB_ALVDATA

    EXCEPTIONS

    PROGRAM_ERROR=1

    OTHERS=2.
