我说说我的想法。手机往一个地址发组播消息，把自己的IP地址，端口发送出去。另一端接收数据包，解析出IP地址，端口，不就可以进行Socket通讯了吗？

不好意思，您的IpAdapter是不是自己编写的类？如果是的话，请不吝赐教把IpAdapter以及前台xml代码都贴出来好吗？

换个思路的话，我想将一台手机设置成静态的ip，然后另一台直接去连接这个ip，
可是为什么设置的静态ip没有起作用呢？？

连接一般要先发现对方主机，然后再建立连接
发现的过程可以有好多种
你可以去那台机器上执行个命令一查就能知道，这是笨办法，也是连的机器不多的偷懒办法
也可以对局域网进行一下扫描，PING或者其它的什么方式都行，
其实也可以直接对局域网所有IP对要连的端口进行连接，如果有主机并能连上，肯定是能连的上，也省的专门去扫描了。。。。
希望对你有用

我也想知道，或许可以循环ping完局域网内所有IP，但这个肯定很慢。坐等高手！

System.exit(0);
finish();
这样用要分清楚，不然出现错误。
