1、添加权限<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.BLUETOOTH" />
2、得到蓝牙适配器BluetoothAdapter mBtAdapter = BluetoothAdapter.getDefaultAdapter();
3、搜索设备 mBtAdapter.startDiscovery();
4、在广播中得到蓝牙设备BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
5、获取蓝牙的名称和地址device.getName() + "\n" + device.getAddress()
连接设备：BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address);
开子线程连接设备BluetoothSocket tmp = device.createRfcommSocketToServiceRecord( MY_UUID_SECURE);
连接成功后InputStream tmpIn = socket.getInputStream();
OutputStream tmpOut =socket.getOutputStream(); 就可以进行通信了
6、关闭蓝牙mBtAdapter.disable()

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)) {
// 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) {
mNewDevicesArrayAdapter.add(device.getName() + "\n" + device.getAddress());
}
// When discovery is finished, change the Activity title
} else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {
setProgressBarIndeterminateVisibility(false);
setTitle(R.string.select_device);
if (mNewDevicesArrayAdapter.getCount() == 0) {
String noDevices = getResources().getText(R.string.none_found).toString();
mNewDevicesArrayAdapter.add(noDevices);
}
}
}
};
