急！急！急！我是搞java得由于公司有个项目没有android人手，让我做了一个app。马上就要交付测试了，现在遇到这样的问题：启动Android Socket服务端时报错说不让在主线程启动，找了一下相关资料说将线程启动到后台可是不知道怎么改，这是我的代码。
ServerSocket server;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Button bt_action = (Button) findViewById(R.id.bt_action);
bt_action.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
try {
ServerSocket server = new ServerSocket();
while (true) {
// 未连通前线程阻塞，连通后开启一个socket通道线程后继续监听9999端口
Socket socket = server.accept();
System.out.println(socket.getInetAddress()
.getHostAddress() + "连接进入");
new SocketThread(socket).start();
}
} catch (IOException e) {
e.printStackTrace();
}
}
});
}
// 一个服务器端口中监听多个客服端通道线程
class SocketThread extends Thread {
// 所有通道写入流的集合
private final List<PrintWriter> list = new ArrayList<PrintWriter>();
private BufferedReader bufferedReader;
private PrintWriter printWriter;
InputStream in = null;
public SocketThread(Socket socket) throws IOException {
this.bufferedReader = new BufferedReader(new InputStreamReader(
socket.getInputStream()));
this.printWriter = new PrintWriter(socket.getOutputStream());
this.in = socket.getInputStream();
list.add(printWriter);
}
@Override
public void run() {
String string = null;
while (true) {
try {
// 服务器在通道中读到的信息回显给客服端
string = bufferedReader.readLine();
System.out.println("客服端信息：" + string);
for (PrintWriter printWriter : list) {
// printWriter.write("服务器显示：" + string + "\r\n");
printWriter.flush();
}
} catch (IOException e) {
}
}
}
}
new Thread(new Runnable() {
@Override
public void run() {
ServerSocket server = new ServerSocket();
while (true) {
// 未连通前线程阻塞，连通后开启一个socket通道线程后继续监听9999端口
Socket socket = server.accept();
System.out.println(socket.getInetAddress()
.getHostAddress() + "连接进入");
new SocketThread(socket).start();
}
}
}.start();
这样就好了
这就是所谓的长连接吗？能实现服务器改过数据 客户端立即能收到数据吗？
