環(huán)信服務器并不保存用戶的頭像用戶名，但實際開發(fā)需要設置用戶昵稱頭像。下面提供一個簡單的辦法設置用戶的頭像昵稱，這里的頭像昵稱從自己的服務器獲取的并且保存到本地。

1.服務端的設計
服務端設計比較簡單，提供個接口，用戶傳入自己的環(huán)信ID（用戶名）得到相關的用戶列表信息，其中包含用戶頭像昵稱還有其他一些你需要的信息

2.手機端的實現(xiàn)
找了半天找到環(huán)信設置用戶頭像的方法在DemoHelper這個類中，直接貼代碼吧

/*** Global listener* If this event already handled by an activity, you don't need handle it again* activityList.size() <= 0 means all activities already in background or not in Activity Stack*/protected void registerMessageListener() {messageListener = new EMMessageListener() {private BroadcastReceiver broadCastReceiver = null;@Overridepublic void onMessageReceived(List<EMMessage> messages) {for (EMMessage message : messages) {EMLog.d(TAG, "onMessageReceived id : " + message.getMsgId());String hxIdFrom=message.getFrom();if(SQUser.init().getUserGropMemData(appContext)!=null){groupMemList.clear();groupMemList = SQUser.init().getUserGropMemData(appContext).getRData();Log.d("這里的信息獲取到額", ""+groupMemList.size());}for (int i = 0; i <groupMemList.size() ; i++) {//接收并處理擴展消息if(message.getUserName().equals(groupMemList.get(i).getHx_user_name())){userName=groupMemList.get(i).getUser_name()+groupMemList.get(i).getDuty();userPic="http://img5.duitang.com/uploads/item/201508/30/20150830132007_TjANX.thumb.224_0.jpeg";}}System.out.println("helper接收到的用戶名："+userName+"helper接收到的id："+"helper頭像："+userPic);EaseUser easeUser=new EaseUser(hxIdFrom);//設置用戶頭像easeUser.setAvatar(userPic);//設置用戶昵稱easeUser.setNick(userName);//存入內存getContactList();contactList.put(hxIdFrom,easeUser);//存入dbUserDao dao=new UserDao(appContext);List<EaseUser> users=new ArrayList<EaseUser>();users.add(easeUser);dao.saveContactList(users);// in background, do not refresh UI, notify it in notification barif(!easeUI.hasForegroundActivies()){getNotifier().onNewMsg(message);}}}@Overridepublic void onCmdMessageReceived(List<EMMessage> messages) {for (EMMessage message : messages) {EMLog.d(TAG, "receive command message");//get message bodyEMCmdMessageBody cmdMsgBody = (EMCmdMessageBody) message.getBody();final String action = cmdMsgBody.action();//獲取自定義action//red packet code : 處理紅包回執(zhí)透傳消息if(!easeUI.hasForegroundActivies()){if (action.equals(RPConstant.REFRESH_GROUP_RED_PACKET_ACTION)){RedPacketUtil.receiveRedPacketAckMessage(message);broadcastManager.sendBroadcast(new Intent(RPConstant.REFRESH_GROUP_RED_PACKET_ACTION));}}if (action.equals("__Call_ReqP2P_ConferencePattern")) {String title = message.getStringAttribute("em_apns_ext", "conference call");Toast.makeText(appContext, title, Toast.LENGTH_LONG).show();}//end of red packet code//獲取擴展屬性 此處省略//maybe you need get extension of your message//message.getStringAttribute("");EMLog.d(TAG, String.format("Command：action:%s,message:%s", action,message.toString()));}}@Overridepublic void onMessageRead(List<EMMessage> messages) {}@Overridepublic void onMessageDelivered(List<EMMessage> message) {}@Overridepublic void onMessageRecalled(List<EMMessage> messages) {for (EMMessage msg : messages) {if(msg.getChatType() == ChatType.GroupChat && EaseAtMessageHelper.get().isAtMeMsg(msg)){EaseAtMessageHelper.get().removeAtMeGroup(msg.getTo());}EMMessage msgNotification = EMMessage.createReceiveMessage(Type.TXT);EMTextMessageBody txtBody = new EMTextMessageBody(String.format(appContext.getString(R.string.msg_recall_by_user), msg.getFrom()));msgNotification.addBody(txtBody);msgNotification.setFrom(msg.getFrom());msgNotification.setTo(msg.getTo());msgNotification.setUnread(false);msgNotification.setMsgTime(msg.getMsgTime());msgNotification.setLocalTime(msg.getMsgTime());msgNotification.setChatType(msg.getChatType());msgNotification.setAttribute(Constant.MESSAGE_TYPE_RECALL, true);EMClient.getInstance().chatManager().saveMessage(msgNotification);}}@Overridepublic void onMessageChanged(EMMessage message, Object change) {EMLog.d(TAG, "change:");EMLog.d(TAG, "change:" + change);}};EMClient.getInstance().chatManager().addMessageListener(messageListener);}

如上，這里的onMessageReceived(List messages)
是全局的消息監(jiān)聽，這兒收到消息后去對比從我們服務器請求的用戶數(shù)據(jù)并且設置相應的頭像用戶名到數(shù)據(jù)庫中。自己的服務器的數(shù)據(jù)我做了本地緩存.用到的時候取出即可。只要改如下方法即可

@Overridepublic void onMessageReceived(List<EMMessage> messages) {for (EMMessage message : messages) {EMLog.d(TAG, "onMessageReceived id : " + message.getMsgId());String hxIdFrom=message.getFrom();if(SQUser.init().getUserGropMemData(appContext)!=null){groupMemList.clear();groupMemList = SQUser.init().getUserGropMemData(appContext).getRData();Log.d("這里的信息獲取到額", ""+groupMemList.size());}for (int i = 0; i <groupMemList.size() ; i++) {//接收并處理擴展消息if(message.getUserName().equals(groupMemList.get(i).getHx_user_name())){userName=groupMemList.get(i).getUser_name()+groupMemList.get(i).getDuty();userPic="http://img5.duitang.com/uploads/item/201508/30/20150830132007_TjANX.thumb.224_0.jpeg";}}System.out.println("helper接收到的用戶名："+userName+"helper接收到的id："+"helper頭像："+userPic);EaseUser easeUser=new EaseUser(hxIdFrom);easeUser.setAvatar(userPic);easeUser.setNick(userName);//存入內存getContactList();contactList.put(hxIdFrom,easeUser);//存入dbUserDao dao=new UserDao(appContext);List<EaseUser> users=new ArrayList<EaseUser>();users.add(easeUser);dao.saveContactList(users);// in background, do not refresh UI, notify it in notification barif(!easeUI.hasForegroundActivies()){getNotifier().onNewMsg(message);}}}

至此可以顯示別人的昵稱頭像了。。。那么自己的該咋辦。。。

好的研究了半天，可以在這設置，EaseUserUtils找到這個方法

/*** set user avatar** @param username*/public static void setUserAvatar(Context context, String username, ImageView imageView) {EaseUser user = getUserInfo(username);Log.d("這里的用戶名", username);if (user != null && user.getAvatar() != null) {try {int avatarResId = Integer.parseInt(user.getAvatar());Glide.with(context).load(avatarResId).into(imageView);} catch (Exception e) {//use default avatarGlide.with(context).load(user.getAvatar()).diskCacheStrategy(DiskCacheStrategy.ALL).placeholder(R.drawable.ease_default_avatar).into(imageView);}} else {Glide.with(context).load(head).diskCacheStrategy(DiskCacheStrategy.ALL).placeholder(R.drawable.ease_default_avatar).into(imageView);}}

在這個類里面新增個方法，設置當前用戶的頭像昵稱

private static String hxUserName = "";private static String userName = "";private static String head = "";/** 設置我的用戶名 我的頭像* @param hxUserName 當前用的環(huán)信用戶名* @param userName 將要設置的用戶名* @param head 將要設置的用戶頭像地址* */public static void setMyUserInfo(String hxName, String myUserName, String headImg) {userName = myUserName;hxUserName = hxName;head = headImg;}

在setUserAvatar(Context context, String username, ImageView imageView)
中的else中設置頭像昵稱

Glide.with(context).load(head).diskCacheStrategy(DiskCacheStrategy.ALL).placeholder(R.drawable.ease_default_avatar).into(imageView);

OK收工，有什么不懂得可以留言哦
