检索WiFi连接状态（Android）

我已按照following link与本地wifi连接。它工作完美。我能够连接到我的本地WiFi。检索WiFi连接状态（Android）

但是，我真的想要wifi的当前状态，我使用下面的代码来获取wifi的状态。但不幸的是，我只能得到'DISABLED'，'ENABLED'和'SCANNING'的状态，我真的想要接受其他中间状态。

你能告诉我我做错了什么吗？

public class ConnectionChangeReceiver extends BroadcastReceiver { 
    @Override 
    public void onReceive(Context context, Intent intent) { 

     NetworkInfo info = intent.getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO); 
     Message msg = new Message(); 
     msg.what = 5; 
     Bundle b = new Bundle(); 
     String sStatus = "UnKnown"; 
     switch(info.getDetailedState()){ 
     case AUTHENTICATING: 
      sStatus = "Authenticating..."; 
      break; 
     case CONNECTED: 
      sStatus = "Connected"; 
      break; 
     case CONNECTING: 
      sStatus = "Connecting..."; 
      break; 
     case DISCONNECTED: 
      sStatus = "Disconnected"; 
      break; 
     case DISCONNECTING: 
      sStatus = "Disconnecting..."; 
      break; 
     case FAILED: 
      sStatus = "Failed"; 
      break; 
     case IDLE: 
      sStatus = "Idle"; 
      break; 
     case OBTAINING_IPADDR : 
      sStatus = "Obtaining IP Address..."; 
      break; 
     case SCANNING: 
      sStatus = "Scanning..."; 
      break; 
     case SUSPENDED: 
      sStatus = "Suspended"; 
      break; 
     } 
     b.putString("status", sStatus); 
     msg.setData(b); 
     mHandler.sendMessage(msg); 
    } 
}

我注册的广播接收机按以下方式

IntentFilter filter = new IntentFilter(
     ConnectivityManager.CONNECTIVITY_ACTION); 
    registerReceiver(networkStateReceiver, filter);

这可能是其他的可能性永远不会被你的设备上执行报告 - 它可能不会理会报告具有这种粒度。我认为你从来没有看到你在那里默认的“未知”？ – 2012-04-26 06:29:44

我无法注册registerReceiver（mReceiver，mIntentFilter）; 。我应该包含一些额外的清单权限。 – 2012-04-26 07:36:09

注册时发生了什么 – 2012-04-26 10:39:04

未提供WifiManager.NETWORK_STATE_CHANGED_ACTION请求者状态。如果您希望请求方状态，则为WifiManager.SUPPLICANT_STATE_CHANGED_ACTION添加意向过滤器 – 2017-05-19 17:32:04

而不是使用

NetworkInfo info = intent.getParcelableExtra(ConnectivityManager 
                  .EXTRA_NETWORK_INFO);

尝试使用

int extraWifiState = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE , 
    WifiManager.WIFI_STATE_UNKNOWN);

感谢您的链接和答案。但我无法检索其他状态，如“获取IP地址”。但对于“启用”，“扫描”和“禁用”（+ 1）非常有用。 – 2012-04-26 14:28:01

一个reciver此代码：

IntentFilter mIntentFilter = new IntentFilter(); 
mIntentFilter.addAction(WifiManager.SUPPLICANT_STATE_CHANGED_ACTION); 
registerReceiver(receiverWifi, mIntentFilter); 


class WifiReceiver extends BroadcastReceiver { 
    @Override 
    public void onReceive(Context c, Intent intent) { 
     String action = intent.getAction(); 
     if(action.equals(WifiManager.SUPPLICANT_STATE_CHANGED_ACTION)){ 
      Log.d("WifiReceiver", ">>>>SUPPLICANT_STATE_CHANGED_ACTION<<<<<<"); 
      SupplicantState supl_state=((SupplicantState)intent.getParcelableExtra(WifiManager.EXTRA_NEW_STATE)); 
      switch(supl_state){ 
      case ASSOCIATED:Log.i("SupplicantState", "ASSOCIATED"); 
       break; 
      case ASSOCIATING:Log.i("SupplicantState", "ASSOCIATING"); 
       break; 
      case AUTHENTICATING:Log.i("SupplicantState", "Authenticating..."); 
       break; 
      case COMPLETED:Log.i("SupplicantState", "Connected");
