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);
