检查手机是否正在使用WIFI或数据/3G [英] Check whether mobile is using WIFI or Data/3G

问题描述

假设设备上同时启用了WIFI和数据/3G，如何检查用户当前是否正在通过wifi使用互联网或数据计划(假设它们都已启用).因此，我不需要检查它们是启用还是禁用，我想检测用户实际使用的是哪个.

Assuming that both WIFI and Data/3G are enabled on a device, how do I check if the user is currently using the internet over the wifi or the data plan assuming they are both enabled. So I don't need to check if they are enabled or disabled, I would like to detect which one is the user actually using.

我一直在做以下事情，这是唯一的解决方法吗?

I've been doing the following, is this the only solution?

WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
if (WifiInfo.getDetailedStateOf(wifiInfo.getSupplicantState()) == NetworkInfo.DetailedState.CONNECTED) {
    String ssid = wifiInfo.getSSID();
}

推荐答案

void chkStatus() {
    final ConnectivityManager connMgr = (ConnectivityManager)
    this.getSystemService(Context.CONNECTIVITY_SERVICE);
    final android.net.NetworkInfo wifi = connMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
    final android.net.NetworkInfo mobile = connMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
    if (wifi.isConnectedOrConnecting ()) {
        Toast.makeText(this, "Wifi", Toast.LENGTH_LONG).show();
    } else if (mobile.isConnectedOrConnecting ()) {
        Toast.makeText(this, "Mobile 3G ", Toast.LENGTH_LONG).show();
    } else {
        Toast.makeText(this, "No Network ", Toast.LENGTH_LONG).show();
    }
}
