Android 为什么在SocketChannel中连接不在非阻塞模式下运行?
我试图打开不同主机的套接字,为此我在非阻塞模式下使用SocketChannel:Android 为什么在SocketChannel中连接不在非阻塞模式下运行?,android,Android,我试图打开不同主机的套接字,为此我在非阻塞模式下使用SocketChannel: ListIterator iter = hosts.listIterator(); SocketChannel sChannel = null; while (iter.hasNext()) { Host host = iter.next(); sChannel = SocketChannel.open(); sChannel.configureBlocking(false); s
ListIterator iter = hosts.listIterator();
SocketChannel sChannel = null;
while (iter.hasNext())
{
Host host = iter.next();
sChannel = SocketChannel.open();
sChannel.configureBlocking(false);
sChannel.connect(new InetSocketAddress(host, 80));
}
然后我打电话给finishConnect
问题是连接似乎被阻塞。我在android上看到了同样的行为。无论InetSocketAddress是否通过以下方式实例化,都会出现此问题 新的InetSocketAddressString主机,int端口 新InetSocketAddress InetAddress.getByAddress字节[]ipAddress 新InetSocketAddress InetAddress.getByAddress字符串主机,字节[]ipAddress 我看到的堆栈如下所示

InetAddress.getHostByAddrImpl(byte[]) line: 558
Inet4Address(InetAddress).getHostName() line: 352

您发布的代码显示您在循环中声明了sChannel。你怎么可能稍后打电话给finishConnect?或者使用这些频道
