Question

我正在尝试连接AP的Wi-Fi信号强度。当我尝试运行以下代码时，不会返回任何内容/显示错误。

public class Wifi extends uiscenario {
    public void onReceive(WifiManager wifiManager) throws UiObjectNotFoundException, InterruptedException, RemoteException, IOException {
        System.out.println("level");
        int numberOfLevels=4;
        WifiInfo wifiInfo = wifiManager.getConnectionInfo();
        int level=WifiManager.calculateSignalLevel(wifiInfo.getRssi(), numberOfLevels);
        System.out.println("Bars =" +level);
    }
}

如何获得wifi连接的信号强度，以及如何获得wifi的扫描结果并连接到信号强度最强的wifi？

更新了代码

public class Wifi extends UiScenario { 
       private static WifiManager wifiManager;
           public void wifiscan() throws UiObjectNotFoundException,InterruptedException,RemoteException, IOException { 
           int numberOfLevels=5; 
           WifiInfo wifiInfo = wifiManager.getConnectionInfo();
           int level=WifiManager.calculateSignalLevel(wifiInfo.getRssi(), numberOfLevels);        
           System.out.println("Bars =" +level);
     }
}

在此行中获取错误（WifiInfo wifiInfo = wifiManager.getConnectionInfo（）;）

Answer 1

希望它应该有效。它对我来说很好。

WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);
int linkSpeed = wifiManager.getConnectionInfo().getRssi();

Answer 2

WifiManager wifiManager = (WifiManager)getSystemService(Context.WIFI_SERVICE);
                            int linkSpeed = wifiManager.getConnectionInfo().getRssi();

                            System.out.println("Link Speed is======"+linkSpeed);

Answer 3

检查您的清单使用wifi的权限并阅读手机状态您的代码是完美的，它应该工作其他尝试这个。

WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);
int linkSpeed = wifiManager.getConnectionInfo().getRssi();

连接Wifi的信号强度（未被调用）
