android 蓝牙隐藏对话框 后台配对

     最近在做一个项目用到蓝牙，但是所有蓝牙的操作必须要后台进行，于是网上搜了下找到了方法。。首先需要下面3个方法，通过反射去操作

     

     static public boolean createBond(Class btClass, BluetoothDevice btDevice)throws Exception {Method createBondMethod = btClass.getMethod("createBond");Log.i("life", "createBondMethod = " + createBondMethod.getName());Boolean returnValue = (Boolean) createBondMethod.invoke(btDevice);return returnValue.booleanValue();}static public boolean setPin(Class btClass, BluetoothDevice btDevice,String str) throws Exception {Boolean returnValue = null;try {Method removeBondMethod = btClass.getDeclaredMethod("setPin",new Class[] { byte[].class });returnValue = (Boolean) removeBondMethod.invoke(btDevice,new Object[] { str.getBytes() });Log.i("life", "returnValue = " + returnValue);} catch (SecurityException e) {// throw new RuntimeException(e.getMessage());e.printStackTrace();} catch (IllegalArgumentException e) {// throw new RuntimeException(e.getMessage());e.printStackTrace();} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}return returnValue;}// 取消用户输入static public boolean cancelPairingUserInput(Class btClass,BluetoothDevice device) throws Exception {Method createBondMethod = btClass.getMethod("cancelPairingUserInput");// cancelBondProcess()Boolean returnValue = (Boolean) createBondMethod.invoke(device);Log.i("life", "cancelPairingUserInputreturnValue = " + returnValue);return returnValue.booleanValue();}

     然后监听蓝牙配对的广播  匹配“android.bluetooth.device.action.PAIRING_REQUEST”这个action

  然后分辨调用上面的setPin(mDevice.getClass(), mDevice, "1234"); // 手机和蓝牙采集器配对   createBond(mDevice.getClass(), mDevice);   cancelPairingUserInput(mDevice.getClass(), mDevice);

   其中上面的mDevice是你要去连接的那个蓝牙的对象 ， 1234为配对的pin码
