Question

我知道有很多这样的问题，但是没有一个能解决我的问题。我正在尝试在两个设备之间以编程方式实现蓝牙配对。我能够配对设备，但问题是它需要用户按下我不想在我的应用程序中的配对按钮。我希望它们在没有任何用户交互的情况下连接，或者如果不可能，它应该只要求一个设备按下配对按钮并且应该配对。我有一台三星电视的工作方式，当我尝试连接我的Android手机的蓝牙与它..我的手机上弹出一对引脚请求，当我点击它配对它没有在电视上显示任何东西他们俩都配对了。我需要在我的应用中实现这一点。我已经尝试过这段代码，但它没有取密码并连接它仍然要求输入密码。

public void setBluetoothPairingPin(BluetoothDevice device)
{
    byte[] pinBytes = convertPinToBytes("0000");
    try {
          Log.d(TAG, "Try to set the PIN");
          Method m = device.getClass().getMethod("setPin", byte[].class);
          m.invoke(device, pinBytes);
          Log.d(TAG, "Success to add the PIN.");
          try {
                device.getClass().getMethod("setPairingConfirmation", boolean.class).invoke(device, true);
                Log.d(TAG, "Success to setPairingConfirmation.");
            } catch (Exception e) {
                // TODO Auto-generated catch block
                Log.e(TAG, e.getMessage());
                e.printStackTrace();
            } 
        } catch (Exception e) {
          Log.e(TAG, e.getMessage());
          e.printStackTrace();
        }
}

我一直在寻找解决方案近一个星期。我们非常感谢能够实现上述目标的任何想法/建议。

你应该试试这个......！

private void pairDevice(BluetoothDevice device) {
            try {
                Method method = device.getClass().getMethod("createBond", (Class[]) null);
                method.invoke(device, (Object[]) null);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

和

mAdapter.setData(mDeviceList);
        mAdapter.setListener(new DeviceListAdapter.OnPairButtonClickListener() {            
            @Override
            public void onPairButtonClick(int position) {               
                BluetoothDevice device = mDeviceList.get(position);

                if (device.getBondState() == BluetoothDevice.BOND_BONDED) {
                    unpairDevice(device);
                } else {
                    showToast("Pairing...");
                    pairDevice(device);//here is calling
                }
            }
        });

Answer 2

`You should try this code on while pair button clicked,

String strPsw = "FBK645NKL"
mAdapter.setData(mDeviceList);
mAdapter.setListener(new OnPairButtonClickListener() {

            @Override
            public void onPairButtonClick(int position) {
                BluetoothDevice device = mDeviceList.get(position);

                if (device.getBondState() == BluetoothDevice.BOND_BONDED) {
                    unpairDevice(device);
                }  else {
                    Log.d("mylog", "HAS BOND_BONDED");
                    try {
                        ClsUtils.createBond(device.getClass(), device);
                        ClsUtils.setPin(device.getClass(), device, strPsw); //
                        ClsUtils.createBond(device.getClass(), device);
//                      remoteDevice = device; // ?remoteDevice
                        result = true;
                    } catch (Exception e) {
                        // TODO Auto-generated catch block
                        Log.d("mylog", "setPiN failed!");
                        e.printStackTrace();
                    }
                }
                return;
            }

        });

and You must write a code for ClsUtils.java 

//ClsUtils code for Bluetooth Device Pairing and Bonding...
