Listening to WIFI Status

I want the listener to listen to the status of the wireless network, can someone help me with my code.

import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;

...

 TelephonyManager wTelephonyManager;

...

     wTelephonyManager=(TelephonyManager)getSystemService(Context.WIFI_SERVICE);
    wTelephonyManager.listen(new PhoneL(),PhoneStateListener.LISTEN_DATA_CONNECTION_STATE);
    connManager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);

// here is the case that I use so that I want to listen to the Wi-Fi change and the above code is in onCreate {}

class PhoneL extends PhoneStateListener

{   






    public void onWifiStateChanged(int state, String nesto)
    {
         mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
            //mWifi.isConnectedOrConnecting()
             if(mWifi.isConnectedOrConnecting())
             {
                 Toast.makeText(WifiActivity.this,"Ima WIFI",Toast.LENGTH_LONG).show();     
             }
             else
             {
                 Toast.makeText(WifiActivity.this,"! NEMA WIFI",Toast.LENGTH_LONG).show(); 
             }


    }

}

// Can someone help me create a listener that will listen to wifi status and check if Wi-Fi is connected or connect if I do not want to enable data packet traffic via 3g / 4g

If you want to listen to the signal level, you can also listen to:

WifiManager.RSSI_CHANGED_ACTION
