    If you want to get the strength of some wifi , you can use wifi manager class and can get list of available wifis like this

      WifiManager manager;
        manager = (WifiManager) getSystemService(WIFI_SERVICE);
        List<ScanResult> res = manager.getScanResults();
        int level = getPowerPercentage(res.get(0).level);
    

    Method to find wifi signal stength like this :

        public int getWifiPercentage(int pow) {
        int i = 0;
        int MIN = -100;
        if (power <= MIN) {
            i = 0;
        } else {
            i = 100 + power;
        }
        return i;
    }
