android WIFi 连接状态之DetailedState

 public enum DetailedState {        /** Ready to start data connection setup. */        IDLE,        /** Searching for an available access point. */        SCANNING,        /** Currently setting up data connection. */        CONNECTING,        /** Network link established, performing authentication. */        AUTHENTICATING,        /** Awaiting response from DHCP server in order to assign IP address information. */        OBTAINING_IPADDR,        /** IP traffic should be available. */        CONNECTED,        /** IP traffic is suspended */        SUSPENDED,        /** Currently tearing down data connection. */        DISCONNECTING,        /** IP traffic not available. */        DISCONNECTED,        /** Attempt to connect failed. */        FAILED,        /** Access to this network is blocked. */        BLOCKED,        /** Link has poor connectivity. */        VERIFYING_POOR_LINK,        /** Checking if network is a captive portal */        CAPTIVE_PORTAL_CHECK    }

IDLE：空闲SCANNING：正在扫描CONNECTING：连接中AUTHENTICATING：正在进行身份验证...OBTAINING_IPADDR：正在获取Ip地址CONNECTED：已连接SUSPENDED：已暂停DISCONNECTING：正在断开连接...DISCONNECTED：已断开FAILED：失败BLOCKED：已阻止VERIFYING_POOR_LINK：暂时关闭（网络状况不佳）CAPTIVE_PORTAL_CHECK：判断是否需要浏览器二次登录（本人用6.0手机试了，好像不会走到这一步）关于 CAPTIVE_PORTAL_CHECK的解释，这里有一篇文章

android 系统把CONNECTING，AUTHENTICATING，OBTAINING_IPADDR都规为CONNECTING

  stateMap.put(DetailedState.IDLE, State.DISCONNECTED);        stateMap.put(DetailedState.SCANNING, State.DISCONNECTED);        stateMap.put(DetailedState.CONNECTING, State.CONNECTING);        stateMap.put(DetailedState.AUTHENTICATING, State.CONNECTING);        stateMap.put(DetailedState.OBTAINING_IPADDR, State.CONNECTING);        stateMap.put(DetailedState.VERIFYING_POOR_LINK, State.CONNECTING);        stateMap.put(DetailedState.CAPTIVE_PORTAL_CHECK, State.CONNECTING);        stateMap.put(DetailedState.CONNECTED, State.CONNECTED);        stateMap.put(DetailedState.SUSPENDED, State.SUSPENDED);        stateMap.put(DetailedState.DISCONNECTING, State.DISCONNECTING);        stateMap.put(DetailedState.DISCONNECTED, State.DISCONNECTED);        stateMap.put(DetailedState.FAILED, State.DISCONNECTED);        stateMap.put(DetailedState.BLOCKED, State.DISCONNECTED);
