如何使用Java发现并配对Android蓝牙设备？有什么代码可供我参考吗？

解决方法:

以下代码将在您必须实现客户端和服务器之后发现已配对和未配对设备的列表,该列表负责配对设备并将数据发送到设备,因为您可以利用BluetoothChatSample给你一个主意.

private Set pairedDevices;

public static ArrayList BondedDeviceList;

public static ArrayList NewDeviceList;

public void makeDiscoverable()

{

discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);

discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300);

activity.startActivity(discoverableIntent);

}

//It will Add the paired device in the BondedDeviceList

public void queryPairedDevice(){

pairedDevices = mBluetoothAdapter.getBondedDevices();

// If there are paired devices

if(pairedDevices==null)

{

//No Bonded Devices

}else

{

if (pairedDevices.size() > 0) {

// Loop through paired devices

for (BluetoothDevice device : pairedDevices) {

BondedDeviceList.add(device);

}

BondedDeviceList.add("End");

}

}

}

//Broadcast Receiver will find the Available devices and the discovery finished

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

// When discovery finds a device

if (BluetoothDevice.ACTION_FOUND.equals(action.trim())) {

// Get the BluetoothDevice object from the Intent

BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

// If it's already paired, skip it, because it's been listed already

if (device.getBondState() != BluetoothDevice.BOND_BONDED) {

NewDeviceList.add(device);

}

// When discovery is finished, change the Activity title

} else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {

if (NewDeviceList.isEmpty() == true) {

String noDevices = "No Devices";

NewDeviceList.add(noDevices);

}

System.out.println("Discovery Finished!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");

NewDeviceList.add("End");

}

}

};

//This is query for the bluetooth devices

public void queryDevices(){

actionFoundFilter = new IntentFilter(BluetoothDevice.ACTION_FOUND);

activity.registerReceiver(mReceiver, actionFoundFilter);

// Don't forget to unregister during onDestroy

discoveryFinishedFilter = new IntentFilter(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);

activity.registerReceiver(mReceiver, discoveryFinishedFilter);

// Don't forget to unregister during onDestroy

queryPairedDevice();

mBluetoothAdapter.startDiscovery();

}

//Unregister the receivers

public void unregisterReceiver() {

// Make sure we're not doing discovery anymore

if (mBluetoothAdapter != null) {

mBluetoothAdapter.cancelDiscovery();

}

// Unregister broadcast listeners

activity.unregisterReceiver(mReceiver);

}

干杯.
