1.Action ID 获取
        IViewPart homeworkView =            PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().showView("org.xcc.zzu_wmp.views.HomeWorkView");
         IActionBars bars = homeworkView.getViewSite().getActionBars();
         IToolBarManager actios = bars.getToolBarManager();
         ActionContributionItem contribut = (ActionContributionItem)

         actios.find(PreferenceConstants.P_ZZU_REFRESH);
         contribut.getAction().setEnabled(true);

 

 

        refresh = new Action( {});

        refresh.setEnabled(false);
        refresh.setId(PreferenceConstants.P_ZZU_REFRESH);

2. ActionSet ID 获取
                         
                    IWorkbench wb=PlatformUI.getWorkbench();
                    List<String> actionIDs= new ArrayList<String>();
                    actionIDs.add(PreferenceConstants.P_ZZU_SAVE);
                    actionIDs.add(PreferenceConstants.P_ZZU_DOWNLOAD);
                    actionIDs.add(PreferenceConstants.P_ZZU_UPLOAD);
                   
                    ActionPresentation ap = ((WorkbenchWindow) wb.getActiveWorkbenchWindow()) .getActionPresentation();
                    IActionSet[] sets = ap.getActionSets();
                    if (sets != null) {
                        for (IActionSet set : sets) {
                            PluginActionSet pas = (PluginActionSet) set;
                            IAction[] actions = pas.getPluginActions();
                            if (actions != null&& pas.getDesc().getId().endsWith(PreferenceConstants.P_ZZU_ACTIONSET)) {//ActionSetID
                                for (IAction action : actions) {
                                    if (actionIDs.contains(action.getId())) {
                                        action.setEnabled(store.getBoolean(PreferenceConstants.P_ZZU_ISLOGIN));
                                    }
                                }
                            }
                     }
