接入融云IM-自定义中间提示信息

一、前言

这样的需求也比较常见，实现起来也比较简单。但往往要控制谁能看见，谁不能看见的。

二、效果图

三、解决思路

正常的自定义消息应该你们会了。说下如何控制谁能看见问题。如果要通知栏显示，即消息需要有app服务器发送，服务端发送的api中有个setIsIncludeSender方法。不要通知栏的，app服务器发送透传消息给app，app判断后本地添加。

四、关键的提示消息体和模板代码

@MessageTag(value = "customize_tip_message", flag = 3)

public class CustomizeTipsMessage extends MessageContent {

    public static final int DEFAULT_TYPE = 0; //0不进行任何跳转
    public static final int JUMP_BAIDU_MATCH_TYPE = 1; //跳转到百度真人认证
    public static final int JUMP_MY_AWARD = 2; //跳转到我的奖励（积分界面）
    public static final int JUMP_CHAT_SETTING = 3; //跳转到聊天设置
    public static final int JUMP_GIFT_DIALOG = 4; //弹起送礼物弹框
    private String content; //整体文案，传的是html文本，因为有些文本需要高亮显示
    private int showLeftTip; //默认0不显示 ,1为显示，用int，不用布尔型
    // 示例
    /**
     * tvUsedTime.setText(Html.fromHtml("认证状态：<font color='#aaaaaa'>认证审核中</font>你们好"));
     *  如果接口只需返回“认证状态：<font color='#aaaaaa'>认证审核中</font>你们好”
     */
    private int jumpType; //用于判断点击跳转
    private String outContent; //用于外面会话列表的文案，为空时统一用“温馨提示”文案
