64、通过PickListValuesUtil,Schema查看下拉列表中的值

public class PickListValuesUtil {
    public static Map<String,Object> getPicklistValues(String sObjectName,String sFieldName){
        Map<String,Object> picValues = new Map<String,Object>();
        Map<String,Schema.SObjectType> sObjectDescribeMap = Schema.getGlobalDescribe();
        if(sObjectDescribeMap.containsKey(sObjectName)){
            Map<String,Schema.SObjectField> sObjectFieldMap = sObjectDescribeMap.get(sObjectName).getDescribe().fields.getMap();
            if(sObjectFieldMap.containsKey(sFieldName)){
                Schema.DescribeFieldResult sObjectFieldDescribe = sObjectFieldMap.get(sFieldName).getDescribe();
                List<Schema.PicklistEntry> lPickEntryList = sObjectFieldDescribe.getPicklistValues();
                for (Schema.PicklistEntry tPicklistEntry : lPickEntryList){
                    picValues.put(tPicklistEntry.getValue(), new Map<String,object>{
                         'value'=>tPicklistEntry.getValue(),
                        'isActive'=>tPicklistEntry.getValue(),
                        'isDefaultValue'=>tPicklistEntry.isDefaultValue(),
                        'label'=>tPicklistEntry.getLabel()
                    });
                }
            }else{
                
            }
        }else{
            
        }
        return picValues;
    }
}

下面是调用部分

Map<String,Object> invoice_c = PickListValuesUtil.getPicklistValues('Invoice__c','Status__c');
System.debug(invoice_c);

输出的结果如下图所示

15:32:13:022 USER_DEBUG [2]|DEBUG|
{
Closed={isActive=Closed, isDefaultValue=false, label=Closed, value=Closed}, 
Negotiating={isActive=Negotiating, isDefaultValue=false, label=Negotiating, value=Negotiating},

Pending={isActive=Pending, isDefaultValue=false, label=Pending, value=Pending}
}
