android - getAllNetworkInfo 检测 wifi 或移动连接，但不会同时检测两者

Question

我有一个检查网络连接的功能:

ConnectivityManager cm = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
NetworkInfo[] networkInfos = cm.getAllNetworkInfo();

但是，一旦 Wifi 网络连接上，移动网络就会显示为 DISCONNECTED

我怎么知道两个网络是否已连接？

提前感谢您的宝贵时间。

Answer 1

试试这个:

ConnectivityManager cm = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
NetworkInfo wifi = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
NetworkInfo mobileNet = cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
if(netInfo!=null){
  if(mobileNet.isConnected()){
    System.out.println("Mobile Network is connected");

  }
  if(wifi.isConnected()){
    System.out.println("Wi-fi Network is connected");
  }

}
