在 Android 中获取 WiFi 信号强度 [英] Getting WiFi signal strength in Android

问题描述

我可以使用以下代码以 dBm 为单位获得 WiFi 信号电平.

I can get WiFi signal level in dBm using following code.

for (ScanResult result : wifiScanResultList) {
    int signalLevel = result.level;
}

它给出了负值.当我们看到默认的系统 WiFi 设置并点击连接的 WiFi 网络时，它会给出好"或坏"作为信号强度.我们可以将那些负值过滤为好"信号强度或坏"信号强度的范围是多少?

It gives negative value. When we see the default system WiFi setting and clicked on the connected WiFi network, it gives "Good" or "Bad" as signal strength. What is the range that we can filter those negative vales as "Good" signal strength or "Bad" signal strength?

推荐答案

这是一个旧帖子，但这可能会帮助某人...

its an old post but this might help someone...

WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
int numberOfLevels = 5;
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
int level = WifiManager.calculateSignalLevel(wifiInfo.getRssi(), numberOfLevels);

文档:public static int calculateSignalLevel (int rssi,int numLevels)
