题外话:离开(Left)

public interface RtmChannelListener {
    void onMemberCountUpdated(int var1);

    void onAttributesUpdated(List<RtmChannelAttribute> var1);

    void onMessageReceived(RtmMessage var1, RtmChannelMember var2);

    void onMemberJoined(RtmChannelMember var1);

    void onMemberLeft(RtmChannelMember var1);
}

声网的离开用的是单词 Left …通常这个单词不都是 left or right 吗?

哈哈!!!
