You can check the connection status using the ConnectivityManager : 

ConnectivityManager cm =
    (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo infoRed = cm.getActiveNetworkInfo();
boolean conectado = infoRed.isConnectedOrConnecting();

To discriminate between Wifi or data connection you can consult: 

int tipo = activeNetwork.getType();
switch(tipo){
    case ConnectivityManager.TYPE_WIFI:
        // caso wifi
        break;
    case ConnectivityManager.TYPE_MOBILE:
        // caso telefono datos moviles
        break;
}

More types are found in the ConnectivityManager documentation.

There is documentation on the subject in Spanish at developer.android.com .

Then you create a Toast or a Snackbar with your information: 

int conectadoEstado = (conectado) ? R.string.connectado : R.string.no_conectado;
Snackbar.make(view, connectadoEstado, Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();


int conectadoEstado = (conectado) ? R.string.connectado : R.string.no_conectado;
Toast.makeText(context, conectadoEstado, Toast.LENGTH_SHORT).show();

You can also register a BroadcastReceiver listening by "android.net.conn.CONNECTIVITY_CHANGE", and use ConnectivityManager to determine the exact state of connectivity.
