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             }
30         }
31
32
33     }
34 }

 执行时直接使用：

02     {
03         boolean result = false;
04         BluetoothAdapter bluetoothAdapter = BluetoothAdapter
05                 .getDefaultAdapter();
06
07         bluetoothAdapter.cancelDiscovery();
08
09         if (!bluetoothAdapter.isEnabled())
10         {
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             } //
39
40         }
41         else
42         {
43             Log.d("mylog", "HAS BOND_BONDED");
44             try
45             {
46                 ClsUtils.createBond(device.getClass(), device);
47                 ClsUtils.setPin(device.getClass(), device, strPsw); // 手机和蓝牙采集器配对
48                 ClsUtils.createBond(device.getClass(), device);
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
