// 藍(lán)牙設(shè)備連接程序
private class BluetoothConnect extends Thread
{
      private BluetoothSocket tempSocket;
      private BluetoothDevice tempDevice;

      public BluetoothConnect(BluetoothDevice device)
      {
         BluetoothSocket temp = null;
         tempDevice = device;

         //以下程序用于獲取BluetoothSocket
         try
         {
            temp = tempDevice.createRfcommSocketToServiceRecord(UUID.fromString(BluetoothCOM_UUID));

            Toast.makeText(getApplication(), device.getAddress(), Toast.LENGTH_LONG).show();
         } catch (IOException e) {

            e.printStackTrace();
         }

         tempSocket = temp;
      }
      public void run()
      {
         myBluetoothAdapter.cancelDiscovery();
         //以下程序用于連接藍(lán)牙設(shè)備
         try
         {
            tempSocket.connect();
//             MainActivity.myBluetoothSocket=x;//此處注意

            Message msg = new Message();
            msg.arg1 = 1;
            handler.sendMessage(msg);
         }
         catch (IOException e)
         {
            try
            {
                  tempSocket.close();
                  Message msg = new Message();
                  msg.arg1 = 2;
                  handler.sendMessage(msg);
            }
            catch (IOException ee)
            {

            }
            return;
         }

      } 連接原理，到底是怎么回事？
