最近在处理环信聊天时，需要修改聊天页面的用户昵称和头像，在网上搜索解决方案，发现没有合适，要么看不懂，要么代码太复杂，没办法，只能发挥自己的聪明才智动手解决了。
项目里的环信是基于V3.x的，项目里的聊天包括单聊和群组聊天，所以要同时兼顾这两种模式。
1.首先我们在easyui库里添加两个类：
package com.hyphenate.easeui.model;
/**
* author: chenzheng
* created on: 2017/7/26 17:11
* description:
*/
public class EaseMember {
public String member_hxid;
public String member_headphoto;
public String member_nickname;
}package com.hyphenate.easeui.utils;
import com.hyphenate.easeui.model.EaseMember;
import java.util.ArrayList;
import java.util.List;
/**
* author: chenzheng
* created on: 2017/7/26 17:04
* description:
*/
public class EaseGlobal {
public static List<EaseMember> memberList = new ArrayList<>();
}2.环信自己也说了环信不保存项目的用户信息，所以这里我们需要在自己的项目里处理。
如果是一对一聊天，我们就获取好友列表（网络请求），并赋值：
List<EaseMember> memberList = new ArrayList<>();
for(HxContact hc : contactList){
EaseMember em = new EaseMember();
em.member_hxid = hc.username;
em.member_headphoto = Api.IMAGE_DOMAIN_URL+hc.headPhoto;
em.member_nickname = hc.name;
memberList.add(em);
}
//添加自己的头像和昵称信息
EaseMember em2 = new EaseMember();
em2.member_hxid = Global.userData.user.hxUserName;
em2.member_headphoto = Api.IMAGE_DOMAIN_URL+Global.userData.user.headPhoto;
em2.member_nickname = Global.userData.user.loginName;
memberList.add(em2);
EaseGlobal.memberList = memberList;如果是群组聊天，我们就获取该群组的成员列表（网络请求），并赋值：
List<EaseMember> memberList = new ArrayList<>();
for(TeamMember tm : groupMemberList){
EaseMember em = new EaseMember();
em.member_hxid = tm.chatUsername;
em.member_headphoto = Api.IMAGE_DOMAIN_URL+tm.headPhoto;
em.member_nickname = tm.mgName;
memberList.add(em);
}
//添加自己的头像和昵称信息
EaseMember em2 = new EaseMember();
em2.member_hxid = Global.userData.user.hxUserName;
em2.member_headphoto = Api.IMAGE_DOMAIN_URL+Global.userData.user.headPhoto;
em2.member_nickname = Global.userData.user.loginName;
memberList.add(em2);
EaseGlobal.memberList = memberList;3.最后一步，离成功一步之遥啦！找到EaseChatRow类，在setUpBaseView()方法中将
修改成：
//set nickname and avatar
if(EaseGlobal.memberList.size()>0){
if (message.direct() == Direct.SEND) {
for(EaseMember em : EaseGlobal.memberList){
if(em.member_hxid.equals(EMClient.getInstance().getCurrentUser())){
Glide.with(context).load(em.member_headphoto).into(userAvatarView);
break;
}
}
} else {
for(EaseMember em : EaseGlobal.memberList){
if(em.member_hxid.equals(message.getFrom())){
Glide.with(context).load(em.member_headphoto).into(userAvatarView);
usernickView.setText(em.member_nickname);
break;
}
}
}
}else {
if (message.direct() == Direct.SEND) {
EaseUserUtils.setUserAvatar(context, EMClient.getInstance().getCurrentUser(), userAvatarView);
} else {
EaseUserUtils.setUserAvatar(context, message.getFrom(), userAvatarView);
EaseUserUtils.setUserNick(message.getFrom(), usernickView);
}
}这种解决方法我认为非常的棒，有木有，扩张性高，对任意项目都适用，而且，不会影响原有功能！
