自定义音讯 蕴含 list 数组
公司产品越来越简单,业务线也一直的减少,我的项目中聊天模块应用了融云的 sdk,然而 sdk 中自带的音讯类型无限,不能满足产品须要的多张图片布局的音讯类型,只能自定义一个,然而发现没有蕴含 list 的音讯例子,实现起来有点繁琐,这边给大家参考下。
——– 音讯体 ———-
- 新建一自定义音讯类,继承 MessageContent
2. 实现 encode() 办法,该办法的性能是将音讯属性封装成 json 串,再将 json 串转成 byte 数组,该办法会在发消息时调用
留神:要在这个办法外面加上这句话用来携带用户信息
if (getJSONUserInfo() != null){
jsonObj.putOpt("user", getJSONUserInfo());
}
3. 笼罩父类的 MessageContent(byte[] data) 构造方法,该办法将对收到的音讯进行解析,先由 byte 转成 json 字符串,再将 json 中内容取出赋值给音讯属性。
留神:要在这个办法外面加上这句话用来解析携带用户信息
if (jsonObj.has(“user”))
setUserInfo(parseJsonToUserInfo(jsonObj.getJSONObject("user")));
4.MessageContent 已实现 Parcelable 接口,自定义音讯类也须要实现 Parcelable
5. 减少注解信息:注解名:MessageTag;属性:value,flag;value 即 ObjectName 是音讯的惟一标识不能够反复,
开发者命名时不能以 RC 结尾,防止和融云内置音讯抵触;flag 是用来定义音讯的可操作状态。
flag 值如下表:
枚举值 阐明
MessageTag.NONE 为空值,不示意任何意义,发送的自定义音讯不会在会话页面和会话列表中展现。
MessageTag.ISCOUNTED 示意客户端收到音讯后,要进行未读音讯计数(未读音讯数减少 1),所有内容型音讯都应该设置此值。非内容类音讯暂不反对音讯计数。
MessageTag.ISPERSISTED 示意客户端收到音讯后,要进行存储,并在之后能够通过接口查问,存储后会在会话界面中显示。
MessageTag.STATUS 在本地不存储,不计入未读数,并且如果对方不在线,服务器会间接抛弃该音讯,对方如果之后再上线也不会再收到此音讯(聊天室类型除外,此类音讯聊天室会视为一般音讯)。
6. 自定义音讯应在 init 后注册 RongIM.registerMessageType(CustomizeMessage.class);
