android蓝牙自动配对连接的具体代码如下: 1. 获取蓝牙适配器BluetoothAdapter blueadapter=BluetoothAdapter.getDefaultAdapter(); 如果BluetoothAdapter 为null,说明android手机没有蓝牙模块。 2. 判断蓝牙模块是否开启,blueadapter.isEnabled() true表示已经开启,false表示蓝牙并没启用。 3. 启动配置蓝牙可见模式,即进入可配对模式Intent in=new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE); in.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 200); startActivity(in); ,200就表示200秒。 4. 获取蓝牙适配器中已经配对的设备Set<BluetoothDevice> device=blueadapter.getBondedDevices(); 当然,还需要在androidManifest.xml中声明蓝牙的权限 <uses-permission android:name="android.permission.BLUETOOTH" /> <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" /> 5.自动配对设置Pin值 static public boolean autoBond(Class btClass, BluetoothDevice device, String strPin) throws Exception { Method autoBondMethod = btClass.getMethod("setPin", new Class[] { byte[].class }

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
Log.d("mylog", "setPiN failed!");
e.printStackTrace();
}
}
return result;
}</b>

这个还是一样回弹出来
