从列表视图获取选定的ID

Question

我们具有用于多用户日历功能的自定义功能，我们使用vf页面覆盖新的事件标准按钮。我们使用“事件”标准控制器和一个扩展操作。

我们要为所选的多个用户创建事件记录。

请找到我们要求采取行动的以下扩展程序

public class CreateNewTaskController {
public Task currentTask {get; set;}
public Event currentEvent {get; set;}

public CreateNewTaskController(ApexPages.StandardController controller) {
    String objType = controller.getRecord().getSObjectType().getDescribe().getName();


    if(String.isNotBlank(objType) && objType.equalsIgnoreCase('Task')) {
        currentTask = (Task) controller.getRecord();
    }
    else if(String.isNotBlank(objType) && objType.equalsIgnoreCase('Event')) {
        currentEvent = (Event) controller.getRecord();
        System.debug('currentevent'+currentEvent);

    }
}
 public PageReference selectEventRT() {
    Id recordTypeId;
    String eventSubject = '';
    if(currentEvent != null) {
        Id myId = currentEvent.WhatId;
        if(myId == null) {
            myId = currentEvent.WhoId;
        }
        if(myId != null) {
            String sObjName = myId.getSObjectType().getDescribe().getName();
            if(sObjName.equalsIgnoreCase('Lead')) {
                recordTypeId = Schema.SObjectType.Event.getRecordTypeInfosByName().get('Person Account Event').getRecordTypeId();
            }
            if(sObjName.equalsIgnoreCase('Account') || sObjName.equalsIgnoreCase('Contact')) {
                recordTypeId = Schema.SObjectType.Event.getRecordTypeInfosByName().get('Account Event').getRecordTypeId();
                eventSubject = 'Appointment';
            }
            if(recordTypeId == null) {
                recordTypeId = Schema.SObjectType.Event.getRecordTypeInfosByName().get('Other Event').getRecordTypeId();
            }
        }
        else {
            recordTypeId = Schema.SObjectType.Event.getRecordTypeInfosByName().get('Other Event').getRecordTypeId();
        }
        PageReference pgRef = new PageReference('/00U/e');

        if(recordTypeId != null) {
            pgRef.getParameters().put('RecordType',recordTypeId);
      }


        Map<String, String> pageParamMap = new Map<String, String>();
        pageParamMap = ApexPages.currentPage().getParameters();


        for(String paramName : pageParamMap.keySet()) {
            if(paramName.equalsIgnoreCase('sfdc.override')) {
                pgRef.getParameters().put('nooverride', '1');
            }
            else {
                if(paramName != 'save_new') {
                    pgRef.getParameters().put(paramName, pageParamMap.get(paramName));
                }
            }
        }
        if(String.isNotBlank(eventSubject)) {
            pgRef.getParameters().put('title', eventSubject);
            pgRef.getParameters().put('tsk5', eventSubject);
        }
        return pgRef;
    }
    return null;
}
