java - 单击按钮后停止线程

Question

我创建了一个线程并在点击按钮时调用它:

btnUpload.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
         new Thread(new ClientThread()).start();
    }
});

这是我的主线:

class ClientThread implements Runnable {

        @Override
        public void run() {

            try {
                InetAddress serverAddr = InetAddress.getByName(SERVER_IP);

                socket = new Socket(serverAddr, SERVERPORT);

            } catch (UnknownHostException e1) {
                e1.printStackTrace();

            } catch (IOException e1) {
                e1.printStackTrace();

            }

        }

    }

我需要在单击按钮后停止线程。我将如何做？我试过 boolean 、中断方法但没有用。我怎样才能阻止它？请帮助我。

Answer 1

试试这个测试代码:

public class Test3 {
    public static void main(String[] args) throws InterruptedException, IOException {
        Thread serverThread = new Thread(new ServerThread());
        serverThread.start();

        ClientThread client = new ClientThread();
        Thread clientThread = new Thread(client);
        clientThread.start();
        Thread.sleep(5000);
        client.closeSocket();
    }
}

class ServerThread implements Runnable {
    @Override
    public void run() {
        try {
            ServerSocket serverSocket = new ServerSocket(7777);
            serverSocket.accept();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

class ClientThread implements Runnable {
    Socket socket;

    public void closeSocket() throws IOException {
        socket.close();
    }

    @Override
    public void run() {
        try {
            InetAddress serverAddr = InetAddress.getByName("127.0.0.1");
            socket = new Socket(serverAddr, 7777);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

这将成功关闭套接字并退出线程。
