如何從掃描網絡獲取percantage中的WI-FI信號強度？

Question

我需要掃描Wifi網絡。

我如何getRssi() WiFi掃描網絡的getRssi() （未連接Wi-Fi網絡）

        int level = WifiManager.calculateSignalLevel(wifi.getConnectionInfo().getRssi(),
                        results.get(i).level);
                int difference = level * 100 / results.get(i).level;

Answer 1

好吧，嘗試一下以發現信號強度

    WifiManager manager;
    manager = (WifiManager) getSystemService(WIFI_SERVICE);
    List<ScanResult> results = manager.getScanResults();
    int level = getPowerPercentage(results.get(0).level);//0 for first scan result and so on.

查找信號強度的方法

    public int getPowerPercentage(int power) {
    int i = 0;
    int MIN_DBM = -100;
    if (power <= MIN_DBM) {
        i = 0;
    } else {
        i = 100 + power;
    }

    return i;
}

希望對您有幫助。
