如何实现android蓝牙开发 自动配对连接,并不弹出提示框

之前做一个android版的蓝牙 与血压计通讯的项目，遇到最大的难题就是自动配对.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<receiver android:name=".BluetoothConnectActivityReceiver" >
<intent-filter>
<action android:name="android.bluetooth.device.action.PAIRING_REQUEST" />
</intent-filter>
</receiver>
自己在收到广播时处理并将预先输入的密码设置进去public class BluetoothConnectActivityReceiver extends BroadcastReceiver
{ String strPsw = "0"; @Override
public void onReceive(Context context, Intent intent)
{
// TODO Auto-generated method stub
if (intent.getAction().equals(
"android.bluetooth.device.action.PAIRING_REQUEST"))
{
BluetoothDevice btDevice = intent
.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); // byte[] pinBytes = BluetoothDevice.convertPinToBytes("1234");
// device.setPin(pinBytes);
Log.i("tag11111", "ddd");
try
{
ClsUtils.setPin(btDevice.getClass(), btDevice, strPsw); // 手机和蓝牙采集器配对
ClsUtils.createBond(btDevice.getClass(), btDevice);
ClsUtils.cancelPairingUserInput(btDevice.getClass(), btDevice);
}
catch (Exception e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
} }

执行时直接使用：public static boolean pair(String strAddr, String strPsw)
{
boolean result = false;
BluetoothAdapter bluetoothAdapter = BluetoothAdapter
.getDefaultAdapter(); bluetoothAdapter.cancelDiscovery(); if (!bluetoothAdapter.isEnabled())
{
bluetoothAdapter.enable();
} if (!BluetoothAdapter.checkBluetoothAddress(strAddr))
{ // 检查蓝牙地址是否有效 Log.d("mylog", "devAdd un effient!");
} BluetoothDevice device = bluetoothAdapter.getRemoteDevice(strAddr); if (device.getBondState() != BluetoothDevice.BOND_BONDED)
{
try
{
Log.d("mylog", "NOT BOND_BONDED");
ClsUtils.setPin(device.getClass(), device, strPsw); // 手机和蓝牙采集器配对
ClsUtils.createBond(device.getClass(), device);
remoteDevice = device; // 配对完毕就把这个设备对象传给全局的remoteDevice
result = true;
}
catch (Exception e)
{
// TODO Auto-generated catch block Log.d("mylog", "setPiN failed!");
e.printStackTrace();
} // }
else
{
Log.d("mylog", "HAS BOND_BONDED");
try
{
ClsUtils.createBond(device.getClass(), device);
ClsUtils.setPin(device.getClass(), device, strPsw); // 手机和蓝牙采集器配对
ClsUtils.createBond(device.getClass(), device);
remoteDevice = device; // 如果绑定成功，就直接把这个设备对象传给全局的remoteDevice
result = true;
}
catch (Exception e)
{
// TODO Auto-generated catch block
Log.d("mylog", "setPiN failed!");
e.printStackTrace();
}
}
return result;
}
