java - 如何在我的应用程序 android 中编写 StreamReader？

Question

我要开发一个从服务器接收消息的 Android 应用程序，但我可以连接到服务器但无法接收消息，因为当我单击 Button 连接 block 时。我认为这是因为循环，但不知道如何以另一种方式解决这种情况，非常感谢您的帮助。

简而言之，我想知道是否有另一种方法来检测我何时收到消息并显示它。

更新:我找到了这样的解决方案:

String IP;

String comando;

PrintWriter msgout;

BufferedReader msgin;

Socket socket;

    private ConnectedThread mConnectedThread;



public void connect(){ //Function to Button connect

    IP = edit.getText().toString();

    try {

     InetAddress serverAddr = InetAddress.getByName(IP); //TCPServer.SERVERIP

     Socket socket = new Socket(serverAddr, 4444); //Porta 4444 serverAddr
     PrintWriter out = new PrintWriter( new BufferedWriter( new  OutputStreamWriter(socket.getOutputStream())),true);
     msgout = out;

     BufferedReader in = new BufferedReader(new  InputStreamReader(socket.getInputStream()));
     msgin = in;

 zav.text1.setText("Connectado.");

  //Wait to mensages
  mConnectedThread = new ConnectedThread();
  mConnectedThread.start();

     } catch (Exception e) {
         text1.setText("Erro! Não conectado." + e);
    }
}

public void send(String message){

     try {

         msg.println(message);


     } catch(Exception e) {
         text1.setText("Erro! Comando não enviado." + e);
 } 
}

private class ConnectedThread extends Thread {

    public void run(){

     while(true){

         //Read
     try {

                String str = msgin.readLine();
                 text1.setText(str);

              } catch(Exception e) {

                  text1.setText("Error" + e);

              } 
         }
   }
}
