如何实现android蓝牙开发 自动配对连接,并不弹出提示框

上网查资料说是用反射createBond（）和setPin（），但测试时进行配对还是会出现提示，但配对是成功了

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	<receiver android:name=".BluetoothConnectActivityReceiver" >

2	<intent-filter>

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

4	</intent-filter>

5	</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
