您可以使用：

获取活动网络信息（）；

ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
if (activeNetwork != null) { 
    // connected to the internet
    if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI) {
        // connected to wifi
    } else if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE) {
        // connected to mobile data
    }
} else {
    // not connected to the internet
}

或者在开关盒中

ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
if (activeNetwork != null) { 
    // connected to the internet
    switch (activeNetwork.getType()) {
        case ConnectivityManager.TYPE_WIFI:
            // connected to wifi
            break;
        case ConnectivityManager.TYPE_MOBILE:
            // connected to mobile data
            break;
        default:
            break;
    }
} else {
    // not connected to the internet
}
