我就开始查找怎么关闭这个蓝牙配对提示框，后面还是伟大的android源码帮助了我。

在源码 BluetoothDevice 类中还有两个隐藏方法

cancelBondProcess（）和cancelPairingUserInput（）

这两个方法一个是取消配对进程一个是取消用户输入

下面是自动配对的代码

Mainfest,xml注册

 

1	<</code>receiver android:name=".BluetoothConnectActivityReceiver" >

2	<</code>intent-filter>

3	<</code>action android:name="android.bluetooth.device.action.PAIRING_REQUEST" />

4	</</code>intent-filter>

5	</</code>receiver>

自己在收到广播时处理并将预先输入的密码设置进去

 

01	public class BluetoothConnectActivityReceiver extends BroadcastReceiver

02

{

03

04	String strPsw = "0";

05

06

@Override

07	public void onReceive(Context context, Intent intent)

08

{

09	// TODO Auto-generated method stub

10	if (intent.getAction().equals(

11	"android.bluetooth.device.action.PAIRING_REQUEST"))

12

{

13	BluetoothDevice btDevice = intent

14	.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

15

16	// byte[] pinBytes = BluetoothDevice.convertPinToBytes("1234");

17	// device.setPin(pinBytes);

18	Log.i("tag11111", "ddd");

19

try

20

{

21	ClsUtils.setPin(btDevice.getClass(), btDevice, strPsw); // 手机和蓝牙采集器配对

22	ClsUtils.createBond(btDevice.getClass(), btDevice);

23	ClsUtils.cancelPairingUserInput(btDevice.getClass(), btDevice);

24

}

25	catch (Exception e)

26

{

27	// TODO Auto-generated catch block

28	e.printStackTrace();

29

}

}

 执行时直接使用：

09	if (!bluetoothAdapter.isEnabled())

{

11	bluetoothAdapter.enable();

12

}

13

14	if (!BluetoothAdapter.checkBluetoothAddress(strAddr))

15	{ // 检查蓝牙地址是否有效

16

17	Log.d("mylog", "devAdd un effient!");

18

}

19

20	BluetoothDevice device = bluetoothAdapter.getRemoteDevice(strAddr);

21

22	if (device.getBondState() != BluetoothDevice.BOND_BONDED)

23

{

24

try

25

{

26	Log.d("mylog", "NOT BOND_BONDED");

27	ClsUtils.setPin(device.getClass(), device, strPsw); // 手机和蓝牙采集器配对

28	ClsUtils.createBond(device.getClass(), device);

29	remoteDevice = device; // 配对完毕就把这个设备对象传给全局的remoteDevice

30	result = true;

31

}

32	catch (Exception e)

33

{

34	// TODO Auto-generated catch block

35

36	Log.d("mylog", "setPiN failed!");

37	e.printStackTrace();

38

} //

40

}

41

else

42

{

49	remoteDevice = device; // 如果绑定成功，就直接把这个设备对象传给全局的remoteDevice

50	result = true;

51

}
