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，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：

<b>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

		return result;
