Display of Huanxin's Avatar and nickname - based on Easeui
I am a college student. I used Huanxin to participate in the competition. I summarize and record the display method of Huanxin's head image and nickname (suffering).
1. First of all, you need to save your nickname and avatar locally when you log in successfully. When you send a message, you need to send your nickname and avatar to the other party.
SpUtils.getInstance().save("userNick",userInfo.getrNick());
SpUtils.getInstance().save("userAvatar",userInfo.getImage());SpUtils is a tool class that uses SharedPreferences to cache information.
2. Then in the chat listening of EaseChatFragment, in the onSetMessageAttributes method, send your nickname and avatar as the extended message. (the fragment of my chat is user-defined, and does not inherit easechattfragment. Therefore, you need to set the listening, rewrite the callback method and replace my fragment separately for the defined easechattfragment. If you are the inherited easechattfragment, you can directly rewrite the onSetMessageAttributes callback method in the fragment class.)
easeChatFragment.setChatFragmentListener(new EaseChatFragment.EaseChatFragmentHelper() {
@Override
public void onSetMessageAttributes(EMMessage message) {
//Set the user nickname to send the extended message
message.setAttribute(Constant.ChatUserNick, SpUtils.getInstance().getString("userNick",""));
//Set the profile of the user to send the extended message
message.setAttribute(Constant.ChatUserPic, SpUtils.getInstance().getString("userAvatar",""));
}
}3. Next, prepare a display class based on the avatar and nickname processing, as follows:
public class HxEaseuiHelper {
private static HxEaseuiHelper instance = null;
protected EMMessageListener messageListener = null;
private Context mContext;
private String username;
private EaseUI easeUI;
private Map<String, EaseUser> contactList;
public synchronized static HxEaseuiHelper getInstance() {
if (instance == null) {
instance = new HxEaseuiHelper();
}
return instance;
}
public void init(Context context) {
EMOptions options = initChatOptions();
//use default options if options is null
mContext = context;
//Get easeui instance
easeUI = EaseUI.getInstance();
//Initialize easeui
easeUI.init(mContext,options);
setEaseUIProviders();
//Set global listening
setGlobalListeners();
//When making packaging confusion, turn off the debug mode to avoid unnecessary resource consumption
EMClient.getInstance().setDebugMode(true);
}
private EMOptions initChatOptions(){
EMOptions options = new EMOptions();
options.setAcceptInvitationAlways(false);
options.setAutoAcceptGroupInvitation(false);
return options;
}
protected void setEaseUIProviders() {
EaseUI easeUI1 = EaseUI.getInstance();
// set profile provider if you want easeUI to handle avatar and nickname
easeUI1.setUserProfileProvider(new EaseUI.EaseUserProfileProvider() {
@Override
public EaseUser getUser(String username) {
return getUserInfo(username);
}
});
}
public EaseUser getUserInfo(String username) {
//Get the EaseUser instance, which is read from memory
//If you read from the server, it's better to cache locally
EaseUser user = null;
if(username == null) {
Toast.makeText(mContext, username+"", Toast.LENGTH_SHORT).show();
return null;
}
//If the user is himself / herself, set his / her own avatar
if(username.equals(EMClient.getInstance().getCurrentUser())){
user=new EaseUser(username);
user.setAvatar((String) SpUtils.getInstance().getString("userAvatar",""));
user.setNick((String)SpUtils.getInstance().getString("userName",""));
return user;
}
//Receive other people's messages and set their avatars
if (contactList!=null && contactList.containsKey(username)){
user=contactList.get(username);
}else { //If there is no in memory, take out the in local database to memory
contactList=getContactList();
user=contactList.get(username);
}
//Initialize if the user is not your contact
if(user == null){
user = new EaseUser(username);
EaseCommonUtils.setUserInitialLetter(user);
}else {
if (TextUtils.isEmpty(user.getAvatar())){//If the name is blank, the ring letter number will be displayed
user.setNick(user.getUsername());
}
}
return user;
}
/**
*Get all contact information
*
* @return
*/
public Map<String, EaseUser> getContactList() {
if (isLoggedIn() && contactList == null) {
contactList = new HashMap<>();
//UserInfo is your own user's bean class (defined user class)
//Get your own contact information through the local database
List<UserInfo> users = Model.getInstance().getDBManager().getContactTableDao().getContacts();
for (UserInfo userInfo: users){
EaseUser easeUser = new EaseUser(userInfo.getHxid());
easeUser.setNick(userInfo.getName());
easeUser.setAvatar(userInfo.getImage());
contactList.put(userInfo.getHxid(),easeUser);
}
}
// return a empty non-null object to avoid app crash
if(contactList == null){
return new Hashtable<String, EaseUser>();
}
return contactList;
}
/**
* if ever logged in
*
* @return
*/
public boolean isLoggedIn() {
return EMClient.getInstance().isLoggedInBefore();
}
/**
* set global listener
*/
protected void setGlobalListeners(){
registerMessageListener();
}
/**
* 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;
@Override
public void onMessageReceived(List<EMMessage> messages) {
for (EMMessage message : messages) {
EMLog.d(TAG, "onMessageReceived id : " + message.getMsgId());
//Receive and process extended messages
String userName=message.getStringAttribute(Constant.ChatUserNick,"");
String userPic=message.getStringAttribute(Constant.ChatUserPic,"");
String hxIdFrom=message.getFrom();
EaseUser easeUser=new EaseUser(hxIdFrom);
easeUser.setAvatar(userPic);
easeUser.setNick(userName);
//Memory in memory
getContactList();
contactList.put(hxIdFrom,easeUser);
UserInfo userInfo = new UserInfo(hxIdFrom);
userInfo.setName(userName);
userInfo.setImage(userPic);
//Save to db, save the contact information to the local database. I create my own contact database for all users on my mobile phone
ContactTableDao dao = Model.getInstance().getDBManager().getContactTableDao();
List<UserInfo> users=new ArrayList<UserInfo>();
users.add(userInfo);
dao.saveContacts(users,true);
// in background, do not refresh UI, notify it in notification bar
//Set local message push notification
if(!easeUI.hasForegroundActivies()){
getNotifier().onNewMsg(message);
}
}
}
@Override
public void onCmdMessageReceived(List<EMMessage> messages) {
for (EMMessage message : messages) {
EMLog.d(TAG, "receive command message");
//get message body
//end of red packet code
//Get extended properties omitted here
//maybe you need get extension of your message
//message.getStringAttribute("");
//Receive and process extended messages
String userName=message.getStringAttribute(Constant.ChatUserNick,"");
String userPic=message.getStringAttribute(Constant.ChatUserPic,"");
String hxIdFrom=message.getFrom();
EaseUser easeUser=new EaseUser(hxIdFrom);
easeUser.setAvatar(userPic);
easeUser.setNick(userName);
//Memory in memory
getContactList();
contactList.put(hxIdFrom,easeUser);
UserInfo userInfo = new UserInfo(hxIdFrom);
userInfo.setName(userName);
userInfo.setImage(userPic);
//Deposit in db
ContactTableDao dao = Model.getInstance().getDBManager().getContactTableDao();
List<UserInfo> users=new ArrayList<UserInfo>();
users.add(userInfo);
dao.saveContacts(users,true);
// in background, do not refresh UI, notify it in notification bar
//Set local message push notification
if(!easeUI.hasForegroundActivies()){
getNotifier().onNewMsg(message);
}
}
}
@Override
public void onMessageReadAckReceived(List<EMMessage> list) {
}
@Override
public void onMessageDeliveryAckReceived(List<EMMessage> list) {
}
@Override
public void onMessageChanged(EMMessage message, Object change) {
}
};
EMClient.getInstance().chatManager().addMessageListener(messageListener);
}
public EaseNotifier getNotifier(){
return easeUI.getNotifier();
}
}
4.After completion, you need to Application Class:
public class IMApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
HxEaseuiHelper.getInstance().init(this);
}
}5. At this point, the display of the avatar and nickname is completed. Finally, it is necessary to check the EaseChatRow class in the easeui:
private void setUpBaseView() {
......
//set nickname and avatar
if(message.direct() == Direct.SEND){
EaseUserUtils.setUserAvatar(context, EMClient.getInstance().getCurrentUser(), userAvatarView);
}else{
EaseUserUtils.setUserAvatar(context, message.getFrom(), userAvatarView);
EaseUserUtils.setUserNick(message.getFrom(), usernickView);
}
......
}
