我正在尝试制作客户端服务器应用程序。我已经做了孔连接，它工作正常。我的服务器运行我的 PC 和我的客户端到我的 android 手机。我想从客户端向服务器发送和接收对象，我已经让服务器发送对象但我不知道如何在我的客户端中接收它们。我的对象类是 PacketManager。
公共类 PacketManager 实现 Serializable {
public String choise;
public int amount;
//Constructor
PacketManager(String ep,int p){
choise=ep;
amount=p;
}
}
我的 MainActivity ：
public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main);
arrayList = new ArrayList<String>();
mList = (ListView)findViewById(R.id.list);
mAdapter = new MyCustomAdapter(this, arrayList);
mList.setAdapter(mAdapter);
// connect to the server
new connectTask().execute("");
}
public class connectTask extends AsyncTask<String,String,TCPClient> {
@Override
protected TCPClient doInBackground(String... message) {
//we create a TCPClient object and
mTcpClient = new TCPClient(new TCPClient.OnMessageReceived() {
@Override
//here the messageReceived method is implemented
public void messageReceived(String message) {
//this method calls the onProgressUpdate
publishProgress(message);
}
});
mTcpClient.run();
return null;
}
@Override
protected void onProgressUpdate(String... values) {
super.onProgressUpdate(values);
//in the arrayList we add the messaged received from server
arrayList.add(values[0]);
// notify the adapter that the data set has changed. This means that new message received
// from server was added to the list
mAdapter.notifyDataSetChanged();
}
}
}
最后我的客户类：
PrintWriter 输出；BufferedReader 中；
public TCPClient(OnMessageReceived listener) {
mMessageListener = listener;
}
/**
* Sends the message entered by client to the server
* @param message text entered by client
*/
public void sendMessage(String message){
if (out != null && !out.checkError()) {
out.println(message);
out.flush();
}
}
public void stopClient(){
mRun = false;
}
public void run() {
mRun = true;
try {
//here you must put your computer's IP address.
InetAddress serverAddr = InetAddress.getByName(SERVERIP);
Log.e("TCP Client", "C: Connecting...");
//create a socket to make the connection with the server
Socket socket = new Socket(serverAddr, SERVERPORT);
try {
//send the message to the server
out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);
Log.e("TCP Client", "C: Sent.");
Log.e("TCP Client", "C: Done.");
//receive the message which the server sends back
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
//in this while the client listens for the messages sent by the server
while (mRun) {
serverMessage = in.readLine();
if (serverMessage != null && mMessageListener != null) {
//call the method messageReceived from MyActivity class
mMessageListener.messageReceived(serverMessage);
}
serverMessage = null;
}
Log.e("RESPONSE FROM SERVER", "S: Received Message: '" + serverMessage + "'");
} catch (Exception e) {
Log.e("TCP", "S: Error", e);
} finally {
//the socket must be closed. It is not possible to reconnect to this socket
// after it is closed, which means a new socket instance has to be created.
socket.close();
}
} catch (Exception e) {
Log.e("TCP", "C: Error", e);
}
}
//Declare the interface. The method messageReceived(String message) will must be implemented in the MyActivity
//class at on asynckTask doInBackground
public interface OnMessageReceived {
public void messageReceived(String message);
}
}
任何人都可以帮我解决这个问题吗，阿拉连接工作正常，但我想从服务器接收 Pack 对象，但我不知道怎么做。我尝试将 public void messageReceived(String message) 的类型更改为 public void messageReceived(PackageManager Pack) 但后来我遇到了 protected TCPClient doInBackground(String... message) 和 protected void onProgressUpdate(String... values) 的问题.
服务器代码
enter code here public TCPServer(OnMessageReceived messageListener) {
this.messageListener = messageListener;
public void sendMessage(String message) throws IOException{
if (mOut != null && !mOut.checkError()) {
mOut.println(message);
mOut.flush();
}
}@Override
public void run() {
super.run();
running = true;try {System.out.println("S: Connecting...");
//create a server socket. A server socket waits for requests to come in over the network.
ServerSocket serverSocket = new ServerSocket(SERVERPORT);
//create client socket... the method accept() listens for a connection to be made to this socket and accepts it.
Socket client = serverSocket.accept();
System.out.println("S: Receiving...");
try {//sends the message to the client
mOut = new PrintWriter(new BufferedWriter(new OutputStreamWriter(client.getOutputStream())), true);
//read the message received from client
BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));
//in this while we wait to receive messages from client (it's an infinite loop)
//this while it's like a listener for messages
while (running) {
String message = in.readLine();
if (message != null && messageListener != null) {
//call the method messageReceived from ServerBoard class
messageListener.messageReceived(message);
}
}catch (Exception e) {
System.out.println("S: Error");
e.printStackTrace();
} finally {
client.close();
System.out.println("S: Done.");
}
} catch (Exception e) {
System.out.println("S: Error");
e.printStackTrace();
}
}
//Declare the interface. The method messageReceived(String message) will must be implemented in the ServerBoard
//class at on startServer button click
public interface OnMessageReceived {
public void messageReceived(String message);
}
