环信即时聊天步骤

Posted 2020-08-17 linkai1

1:注册账号

2:下载sdk

3:导入modle EaseUI

4:讲model加入到主项目

5:登陆功能:代码如下:

EMClient.getInstance().login(userName,password,new EMCallBack() {//回调

@Override

public void onSuccess() {

EMClient.getInstance().groupManager().loadAllGroups();

EMClient.getInstance().chatManager().loadAllConversations();

Log.d("main", "登录聊天服务器成功！");

 

COnstact();

 

}

 

@Override

public void onProgress(int progress, String status) {

 

}

 

@Override

public void onError(int code, String message) {

Log.d("main", "登录聊天服务器失败！");

}

});

 

6:当登陆成功以后,跳转到联系人列表:

联系人代码如下:

List<String>usernames=

EMClient.getInstance().contactManager().getAllContactsFromServer();

备注:获取联系人必须在子线程执行,更新UI必须在主线程执行.

7:跳转到聊天页面,代码如下:

//new出EaseChatFragment或其子类的实例

EaseChatFragment chatFragment = new EaseChatFragment();

//传入参数

Bundle args = new Bundle();

args.putInt(EaseConstant.EXTRA_CHAT_TYPE, EaseConstant.CHATTYPE_SINGLE);

args.putString(EaseConstant.EXTRA_USER_ID, username);

chatFragment.setArguments(args);

getSupportFragmentManager().beginTransaction().add(R.id.container, chatFragment).commit();

 

8:添加好友功能,代码如下:

EMClient.getInstance().contactManager().addContact("13934127774", "你好");

注意:第一个参数是要加好友的用户名,第二个参数是添加的理由.

添加好友必须在子线程执行.

 

9:同意加好友功能,代码如下:

EMClient.getInstance().contactManager().acceptInvitation(username);

注意:参数是好友用户名.同意添加好友功能必须在子线程执行.

10:拒绝好友功能,代码如下:

EMClient.getInstance().contactManager().declineInvitation(username);

注意:参数为好友用户名,拒绝好友功能必须在子线程执行.

11:监听好友动态功能,代码如下:

EMClient.getInstance().contactManager().setContactListener(new EMContactListener() {

 

@Override

public void onContactAgreed(String username) {

//好友请求被同意

 

Log.d("username", "好友请求被同意" + username);

}

 

@Override

public void onContactRefused(String username) {

//好友请求被拒绝

Log.d("username", "好友请求被拒绝" + username);

}

 

@Override

public void onContactInvited(String username, String reason) {

//收到好友邀请

Log.d("username", "收到好友邀请" + username);

 

 

Message msg = mhandler.obtainMessage();

msg.what = 2;

msg.obj = username;

handler.sendMessage(msg);

 

}

 

@Override

public void onContactDeleted(String username) {

//被删除时回调此方法

Log.d("username", "被删除时回调此方法" + username);

}

 

 

@Override

public void onContactAdded(String username) {

//增加了联系人时回调此方法

Log.d("username", "增加了联系人时回调此方法" + username);

}

});

 

12:即时得到聊天消息功能,代码如下,一般下载application里面

 

//聊天消息

public void ChatListener(){

 

 

EMMessageListener msgListener = new EMMessageListener() {

 

@Override

public void onMessageReceived(List<EMMessage> messages) {

//收到消息

 

Log.d("gggggg",messages.toString());

}

 

@Override

public void onCmdMessageReceived(List<EMMessage> messages) {

//收到透传消息

}

 

@Override

public void onMessageReadAckReceived(List<EMMessage> messages) {

//收到已读回执

}

 

@Override

public void onMessageDeliveryAckReceived(List<EMMessage> message) {

//收到已送达回执

}

 

@Override

public void onMessageChanged(EMMessage message, Object change) {

//消息状态变动

}

};

 

EMClient.getInstance().chatManager().addMessageListener(msgListener);

}

 

 

注意:在导入环信的时候可能遇到V4包与V7包 的冲突,此时需要移除v4包.

解决方案如下:

在build.grade里面v7包下加入加入 exclude module: ‘support-v4‘如下代码:

 

compile (‘com.android.support:appcompat-v7:23.4.0‘){

exclude module: ‘support-v4‘

}
