然后，迭代每个对象:
NetworkInterface intf = en.nextElement();
String name = intf.getName();
这是问题所在.返回值名称"的名称为:rmnet_data1，dymmy0，wlan0，rmnet_usb0，intf，lo，p2p0，sit0. (在我的设备上)我想知道它们的含义.

有关* nix网络接口命名的一些资源
Here's some resources on *nix network interface naming
- a tour of classic Linux network interface names
- new predictable interface names
- a good StackOverflow question
总结:
lo通常代表回送接口(localhost)
lo usually stands for the loopback interface (localhost)
wlan通常代表无线网络接口

rmnet接口通常与 sit接口与通过IPv4进行IPv6隧道关联
p2p接口通常与对等连接相关联(也许您的Android设备的
p2p interfaces are usually associated with peer-to-peer connections (perhaps your Android device's WiFi Direct support?)
dummy接口为回送接口提供特殊别名
dummy interfaces provide special aliases for the loopback interface
