java - 检索 wifi 连接状态(Android)

Question

我已经关注了 following link连接本地wifi。它工作完美。我可以连接到本地 wifi。

但是，我真的想要 wifi 的当前状态，我正在使用以下代码来获取 wifi 的状态。但不幸的是我只能获得'DISABLED'，'ENABLED'和'SCANNING'状态，我真的很想收到其他中间状态。

你能告诉我我哪里做错了吗

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);
    }
}

我通过以下方式注册广播接收器

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

Answer 1

注册接收器:

mIntentFilter = new IntentFilter();
  mIntentFilter.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
  mIntentFilter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
  mIntentFilter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
  mIntentFilter.addAction(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION);
  registerReceiver(mReceiver, mIntentFilter);




public void onReceive(Context context, Intent intent)
   {
    String action  = intent.getAction();
    if(action.equals(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION))
    {
    }else if(action.equals(WifiManager.WIFI_STATE_CHANGED_ACTION))
    {
     int iTemp = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE,
       WifiManager.WIFI_STATE_UNKNOWN);
     LogUtil.d(LOG_SET, "+++++++-----------wifiStateReceiver------+++++++", DEBUG);
     checkState(iTemp);
    }else if(action.equals(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION))
    {
     DetailedState state =WifiInfo.getDetailedStateOf((SupplicantState)
     intent.getParcelableExtra(WifiManager.EXTRA_SUPPLICANT_CONNECTED));
     changeState(state);
     LogUtil.d(LOG_SET, "------------>>>>SUPPLICANT_STATE_CHANGED_ACTION<<<<<<-------", DEBUG);
    }
    else if(action.equals(WifiManager.NETWORK_STATE_CHANGED_ACTION))
    {
        DetailedState state=
       ((NetworkInfo)intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO)).getDetailedState();
       changeState(state);
     }
   }
   private void changeState(DetailedState aState)
    {
     LogUtil.d(LOG_SET, ">>>>>>>>>>>>>>>>>>changeState<<<<<<<<<<<<<<<<"+aState, DEBUG);
   if (aState == DetailedState.SCANNING)
   {
   Log.d("wifiSupplicanState", "SCANNING");
   }
   else if (aState == DetailedState.CONNECTING)
   {
   Log.d("wifiSupplicanState", "CONNECTING");
   }else if(aState == DetailedState.OBTAINING_IPADDR)
   {
   Log.d("wifiSupplicanState", "OBTAINING_IPADDR");
   }
   else if (aState == DetailedState.CONNECTED)
   {
   Log.d("wifiSupplicanState", "CONNECTED");
   }
   else if (aState == DetailedState.DISCONNECTING)
   {
    Log.d("wifiSupplicanState", "DISCONNECTING");
   }
   else if (aState == DetailedState.DISCONNECTED)
   {
    Log.d("wifiSupplicanState", "DISCONNECTTED");
   }
   else if (aState == DetailedState.FAILED)
   {
   }
  }

  public void checkState(int aInt)
  {
   LogUtil.d(LOG_SET,"==>>>>>>>>checkState<<<<<<<<"+aInt, DEBUG);
   if (aInt == WifiManager.WIFI_STATE_ENABLING)
    {
    Log.d("WifiManager", "WIFI_STATE_ENABLING");
    }
   else if (aInt== WifiManager.WIFI_STATE_ENABLED)
   {
   Log.d("WifiManager", "WIFI_STATE_ENABLED");
    }
    else if (aInt == WifiManager.WIFI_STATE_DISABLING)
    {
    Log.d("WifiManager", "WIFI_STATE_DISABLING");
    }
    else if (aInt == WifiManager.WIFI_STATE_DISABLED)
    {
    Log.d("WifiManager", "WIFI_STATE_DISABLED");
    }
  }
