Question

我有一个包含我的服务器的文件，它从客户端应用程序获取内容。如何将服务器收到的内容发送到我的MainActvity？如果我尝试MainActivity main = new MainActivity（）;在服务器文件中，应用程序崩溃。

服务器文件。

class ServerThread implements Runnable {

    public void run() {

        Socket socket = null;
        try {
            serverSocket = new ServerSocket(SERVERPORT);
        } catch (IOException e) {
            e.printStackTrace();
        }
        while (!Thread.currentThread().isInterrupted()) {
            try {
                socket = serverSocket.accept();
                CommunicationThread commThread = new CommunicationThread(socket);
                new Thread(commThread).start();
                connected_server = true;
            } catch (IOException e) {
                connected_server = false;
                e.printStackTrace();
            }
        }
    }
}

class CommunicationThread implements Runnable {
    private Socket clientSocket;
    private BufferedReader input;
    public CommunicationThread(Socket clientSocket) {
        this.clientSocket = clientSocket;
        try {
            this.input = new BufferedReader(new InputStreamReader(this.clientSocket.getInputStream()));

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

    public void run() {
        while (!Thread.currentThread().isInterrupted()) {
            try {
                String read = input.readLine();
                updateConversationHandler.post(new updateUIThread(read));
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

}

class updateUIThread implements Runnable {
    private String msg;
    public updateUIThread(String str) {
        this.msg = str;
    }

    @Override
    public void run() {
        if (msg != null){
          //Where I need to send the received content to the main activity 

            Log.e("INPUT", msg);
        }
    }
}


  Main Activity 
   public class MainActivity extends Activity {
  …
public void  message_recieve(String msg){
   // do stuff with messages 
}



}

您需要实现回调，以便在服务器请求结束时正确接收结果

从文件向MainActivity发送消息（String）
