主要功能是，自身是无线热点，获取连接自身的设备IP列表

GetConnectIP.java

package wifi.localinfo;


import java.io.BufferedReader;
import java.io.FileReader;
import java.util.ArrayList;


public class GetConnectIP {
	static StringBuilder resultList;
	static ArrayList<String> connectedIP;


	public static ArrayList<String> getAllIp()
	{
		try {
			connectedIP = getConnectIp();
		} catch (Exception e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}
		resultList = new StringBuilder();
		for (String ip : connectedIP) {
			resultList.append(ip);
			try {
				connectedIP = getConnectIp();
			} catch (Exception e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
		return connectedIP;
	}


	public static String getOneIp()
	{
		return getAllIp().get(1);
	}
	
	private static ArrayList<String> getConnectIp() throws Exception {
		ArrayList<String> connectIpList = new ArrayList<String>();
		BufferedReader br = new BufferedReader(new FileReader("/proc/net/arp"));
		String line;
		while ((line = br.readLine()) != null) {
			String[] splitted = line.split(" +");
			if (splitted != null && splitted.length >= 4) {
				String ip = splitted[0];
				connectIpList.add(ip);
			}
		}
		return connectIpList;
	}
}

具体调用

        GetConnectIP.getOneIp();
