我如何获得有关连接到我的Android手机的wifi信号强度的信息？

I'm trying to create an app that can tell you the signal strength of a wifi access point it's currently connected to. I'm using Android Studios and am a beginner. How do I retrieve this information? Any methods would be helpful.

public void onReceive(WifiManager wifiManager) {
                      int numberOfLevels=5;
                      WifiInfo wifiInfo = wifiManager.getConnectionInfo();
                      int level=WifiManager.calculateSignalLevel(wifiInfo.getRssi(), numberOfLevels);
                      System.out.println("Bars =" +level);
                }
