使用方法：

 

  public static boolean pair(String strAddr, String strPsw){   boolean result=false;   BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();         bluetoothAdapter.cancelDiscovery();         if(!bluetoothAdapter.isEnabled()){    bluetoothAdapter.enable();     }     if(!BluetoothAdapter.checkBluetoothAddress(strAddr)){     //检查蓝牙地址是否有效        Log.d("mylog","devAdd un effient!");   }      BluetoothDevice device = bluetoothAdapter.getRemoteDevice(strAddr);       if (device.getBondState() != BluetoothDevice.BOND_BONDED) {     try {     ClsUtils.setPin(device.getClass(), device, strPsw);    //手机和蓝牙采集器配对     ClsUtils.createBond(device.getClass(), device);     remoteDevice = device;           //配对完毕就把这个设备对象传给全局的remoteDevice     result=true;    } catch (Exception e) {     // TODO Auto-generated catch block     Log.d("mylog","setPiN failed!");     e.printStackTrace();    } //        }   else    {    remoteDevice = device; //如果绑定成功，就直接把这个设备对象传给全局的remoteDevice    result=true;   }  return result; }
