Android群组回调初始化问题

群组事件监听 建议在 初始化的时候调用EMClient.getInstance().groupManager().addGroupChangeListener(new EMGroupChangeListener() { @Override public void onInvitationReceived(String groupId, String groupName, String inviter, String reason) { //接收到群组加入邀请 } @Override public void onRequestToJoinReceived(String groupId, String groupName, String applyer, String reason) { //用户申请加入群 } @Override public void onRequestToJoinAccepted(String groupId, String groupName, String accepter) { //加群申请被同意 } @Override public void onRequestToJoinDeclined(String groupId, String groupName, String decliner, String reason) { //加群申请被拒绝 } @Override public void onInvitationAccepted(String groupId, String inviter, String reason) { //群组邀请被同意 } @Override public void onInvitationDeclined(String groupId, String invitee, String reason) { //群组邀请被拒绝 } @Override public void onAutoAcceptInvitationFromGroup(String groupId, String inviter, String inviteMessage) { //接收邀请时自动加入到群组的通知 } @Override public void onMuteListAdded(String groupId, final List<String> mutes, final long muteExpire) { //成员禁言的通知 } @Override public void onMuteListRemoved(String groupId, final List<String> mutes) { //成员从禁言列表里移除通知 } @Override public void onAdminAdded(String groupId, String administrator) { //增加管理员的通知 } @Override public void onAdminRemoved(String groupId, String administrator) { //管理员移除的通知 } @Override public void onOwnerChanged(String groupId, String newOwner, String oldOwner) { //群所有者变动通知 } @Override public void onMemberJoined(final String groupId, final String member){ //群组加入新成员通知 } @Override public void onMemberExited(final String groupId, final String member) { //群成员退出通知 } @Override public void onAnnouncementChanged(String groupId, String announcement) { //群公告变动通知 } @Override public void onSharedFileAdded(String groupId, EMMucSharedFile sharedFile) { //增加共享文件的通知 } @Override public void onSharedFileDeleted(String groupId, String fileId) { //群共享文件删除通知 } });
