/**
 * 消息类型
 */
enum class MessageType 
    MESSAGE_COMMENT, MESSAGE_GOODS;

    fun getKey(): String 
        return when (this) 
            MESSAGE_COMMENT -> "MESSAGE_COMMENT"
            MESSAGE_GOODS -> "MESSAGE_GOODS"
        
    

    fun getTitle(): String 
        return when (this) 
            MESSAGE_COMMENT -> "收到的评论"
            MESSAGE_GOODS -> "收到的赞"
        
    

  val viewList = ArrayList<CoreFragment>()
        MessageType.values().forEach 
            viewList.add(MessageReceivedCommentFragment(it.getKey()))
  
  
  val titleArray = MessageType.values().map  it.getTitle() 

/**
 * 状态类型
 */
enum class STATUS_TYPE_MODE(val key: String, val value: String) 
    //状态1，状态2
    STATEONE("STATEONE", "状态一"), ATTENTITWO("ATTENTITWO", "状态二")


使用方式
STATUS_TYPE_MODE.STATEONE.key
STATUS_TYPE_MODE.STATEONE.value

enum class ChangeReason(val key: String, val value: String) 
    AAA("INVITE_REGISTRATION", "邀请注册"),
    BBB("USER_REGISTRATION", "用户注册"),
 
    companion object 
        fun getChangeReason(key: String?): String 
            return values().firstOrNull  it.key == key ?.value ?: "--"
        
    

使用方法　item.reason未后台返回的的ｋｅｙ
　　IntegralChangeReason.getChangeReason(item.reason)
