在Xamarin.Android中找不到PairingParams.PAIRING_VARIANT_CONSENT

Question

我遇到过这样的问题，当配对请求发生时，我得到了下面的PairingParams.PAIRING_VARIANT_CONSENT (= 3)配对变体，但它在...

object obj = intent.GetParcelableExtra(BluetoothDevice.ExtraDevice);
BluetoothDevice device = (obj as BluetoothDevice)!;
var extraPairingVariant = intent.GetIntExtra(BluetoothDevice.ExtraPairingVariant, 0);
switch (extraPairingVariant)
{
  case BluetoothDevice.PairingVariantPin:
  {
    ...
  }
    break;
  case BluetoothDevice.PairingVariantPasskeyConfirmation:
  {
    ...
  }
    break;
  case \* 3, what constant should be here ?? *\
  {
    ...
  }
    break;
}

... BluetoothDevice不包含像PAIRING_VARIANT_CONSENT这样的东西...

有没有人面临同样的问题？

Answer 1

在我的例子中，我调用abortBroadcast()不显示pin对话框，但仅当BluetoothDevice.ExtraPairingVariant不是3时才显示。否则，必须显示一个对话框，让用户接受配对。当您删除已配对的设备并要求重新配对时，就会出现此状态。(https://developer.android.com/reference/com/google/android/things/bluetooth/PairingParams.html#pairing_variant_consent)

BluetoothDevice device = (BluetoothDevice)intent.GetParcelableExtra(BluetoothDevice.ExtraDevice);
if (action == BluetoothDevice.ActionPairingRequest)
        {
            device.SetPin(System.Text.Encoding.UTF8.GetBytes("####"));
            int exraPairingVariant = intent.GetIntExtra(BluetoothDevice.ExtraPairingVariant, 0);
            if (exraPairingVariant == BluetoothDevice.PairingVariantPasskeyConfirmation || exraPairingVariant == BluetoothDevice.PairingVariantPin)
            {
                InvokeAbortBroadcast();
            }
        }
