显示确认对话框以接受连接，bluecove 服务器 java

Question

我按照本教程用 bluecove 做了一个蓝牙服务器：http://luugiathuy.com/2011/02/android-java-bluetooth/ 我想在连接前用 JOptionPane 添加一个确认弹出窗口，但我不知道如何。你能帮助我吗？这是代码：

import com.intel.bluetooth.BluetoothStack;
import javax.bluetooth.DiscoveryAgent; 
import javax.bluetooth.LocalDevice;
import javax.bluetooth.UUID; 
import javax.microedition.io.Connector; 
import javax.microedition.io.StreamConnection; 
import javax.microedition.io.StreamConnectionNotifier; 
import javax.swing.JOptionPane;

public class WaitThread implements Runnable { 
     private GestorPrincipal gestor = GestorPrincipal.getInstancia(); 

 /** * Constructor */ 
 public WaitThread() { }

 @Override 
 public void run() { 
     waitForConnection(); 
 } 

 /** * Waiting for connection from devices */ 
 private void waitForConnection() { 
     // retrieve the local Bluetooth device object 
     LocalDevice local = null;      
     StreamConnectionNotifier notifier; StreamConnection connection = null;   
     // setup the server to listen for connection 
     try { 
        local = LocalDevice.getLocalDevice();
        local.setDiscoverable(DiscoveryAgent.GIAC); 
        UUID uuid = new UUID(80087355); 
        // "04c6093b-0000-1000-8000-00805f9b34fb" 
        String url = "btspp://localhost:" + uuid.toString() + ";name=RemoteBluetooth"; 
        notifier = (StreamConnectionNotifier) Connector.open(url); 
     } 
     catch (Exception e) { 
        e.printStackTrace(); 
        return; 
      } 
      // waiting for connection 
      while (true) { 
        try { 
            System.out.println("Esperando la conexion...");
            gestor.agregarTexto("Esperando la conexion.."); 
            connection = notifier.acceptAndOpen(); 
            Thread processThread = new Thread(new ProcessConnectionThread(connection)); 
             processThread.start(); 
         } 
         catch (Exception e) { 
             e.printStackTrace(); return; 
          } 
     } 
   } 
}`

PD：抱歉我的英语不好，我来自 ARG。

Oracle 已经详细记录了这个名为 "How to Make Dialogs" 的主题，该文档展示了如何创建不同类型的对话框，这些对话框会提示用户一些期望用户输入的内容，并且有些只是用图标显示一些数据。

http://docs.oracle.com/javase/tutorial/uiswing/components/dialog.html

根据您的要求，您可以这样做：

...
 while (true) { 
        try { 
            System.out.println("Esperando la conexion...");
            gestor.agregarTexto("Esperando la conexion..");
            connection = notifier.acceptAndOpen();
            //Ask user if he/she wants to get connected to this device
            int userChoice = JOptionPane.showConfirmDialog(
            null,
            "Would you like to connect to DEVICE_NAME?",
            "Connection Request",
            JOptionPane.YES_NO_OPTION);
            if(userChoice == JOptionPane.YES_OPTION) {
               // Create thread and come out of loop
               Thread processThread = new Thread(new ProcessConnectionThread(connection)); 
               processThread.start();
               break;
            }
            else {
              // user rejected the connection so close the connection here to allow other devices to connect
            }

         } 
         catch (Exception e) { 
             e.printStackTrace(); return; 
          } 
     }
...
