如何检查Wi-Fi Switch状态＆＃x27; ON＆＃x27;或OFF＆＃x27;即使未连接到Android上的WiFi网络

我需要开发一项功能，即使未连接到 Android 上的 WiFi 网络，也需要检查 Wi-Fi 设置状态“开启”或“关闭”！我需要显示一个弹出窗口！

 public static boolean CheckWifiConnection(Context context) {
    ConnectivityManager conMgr = (ConnectivityManager) context.getSystemService (Context.CONNECTIVITY_SERVICE);
    return conMgr.getActiveNetworkInfo() != null
            && conMgr.getActiveNetworkInfo().isAvailable();
}

举个例子：假设我在公交车上，我已经打开了WiFi。它未连接到 wifi 网络，因为附近没有 WiFi 路由器。那么我的应用程序如何知道 wifi 是打开或关闭的。

原文

I need to develop a feature that is required checking Wi-Fi settings state 'ON' or 'OFF' even if not connected to a WiFi network on Android! I need to display a pop up!

 public static boolean CheckWifiConnection(Context context) {
    ConnectivityManager conMgr = (ConnectivityManager) context.getSystemService (Context.CONNECTIVITY_SERVICE);
    return conMgr.getActiveNetworkInfo() != null
            && conMgr.getActiveNetworkInfo().isAvailable();
}

For an example: Think I am in a bus, I have turned on the WiFi. It is not connected to a wifi network, because there is no WiFi router near by. So How can my app knows wifi is on or off.

您可以使用ConnectivityManager获取网络状态

private boolean isNetworkAvailable() {
            ConnectivityManager connectivityManager
                    = (ConnectivityManager) activity.getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
            return activeNetworkInfo != null && activeNetworkInfo.isConnected();
        }

You can use ConnectivityManager to get network status

private boolean isNetworkAvailable() {
            ConnectivityManager connectivityManager
                    = (ConnectivityManager) activity.getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
            return activeNetworkInfo != null && activeNetworkInfo.isConnected();
        }

对于这个问题我可以使用WifiManager。

public static boolean CheckWifiSwitch(Context context) {
    WifiManager wifiMgr = (WifiManager) context.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
    return wifiMgr.isWifiEnabled();
}

WifiManager

For this question I could use WifiManager.

public static boolean CheckWifiSwitch(Context context) {
    WifiManager wifiMgr = (WifiManager) context.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
    return wifiMgr.isWifiEnabled();
}

我认为你应该使用ConnectivityManager。

ConnectivityManager.NetworkCallback networkCallback = new ConnectivityManager.NetworkCallback() {
    @Override
    public void onAvailable(Network network) {
        // network available
    }

    @Override
    public void onLost(Network network) {
        // network unavailable
    }
};

如何检查连接类型

I think you should to use ConnectivityManager.

ConnectivityManager.NetworkCallback networkCallback = new ConnectivityManager.NetworkCallback() {
    @Override
    public void onAvailable(Network network) {
        // network available
    }

    @Override
    public void onLost(Network network) {
        // network unavailable
    }
};
