有没有什么办法可以有力地点击配对键，每当出现蓝牙配对对话框？

Is there any way to forcefully click on "pair button" whenever the Bluetooth pairing dialog appears?

推荐答案

我不知道怎么去进入配对对话框，但是我能够通过以下方式逼配对：

I don't know how to get access to the pairing dialog, but I was able to "force" pairing in the following way:

1）注册一个BroadcastReceiver的行动：

1) register a BroadcastReceiver for the action:

android.bluetooth.device.action.PAIRING_REQUEST

2）一旦接收到的动作，逼PIN码使用反射：

2) once the action is received, "force" the PIN using reflection:

String DEVICE_PIN = "12345";

final BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

if (intent.getAction().equals("android.bluetooth.device.action.PAIRING_REQUEST")) {
    byte[] pin = (byte[]) BluetoothDevice.class.getMethod("convertPinToBytes", String.class).invoke(BluetoothDevice.class, ARDUINO_PIN);
    BluetoothDevice.class.getMethod("setPin", byte[].class).invoke(device, pin); 
}

它为我的GB和ICS（不知道这是否适用于更新的版本）。

It worked for me on GB and ICS (don't know if it works on newer releases).
