使用Android中的Bluetooth API，扫描附近的蓝牙设备，将扫描结果与本地蓝牙设备的名称进行匹配。如果找到名称相同的设备，则自动进行配对。下面是示例代码：

public class AutoPairActivity extends AppCompatActivity {

    private BluetoothAdapter mBluetoothAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

        if (mBluetoothAdapter == null) {
            // Device does not support Bluetooth
            return;
        }

        if (!mBluetoothAdapter.isEnabled()) {
            Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
            startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
        } else {
            // start scanning for devices
            scanForDevices();
        }
    }

    private void scanForDevices() {
        // start discovery
        mBluetoothAdapter.startDiscovery();

        // create BroadcastReceiver for scan results
        BroadcastReceiver receiver = new BroadcastReceiver() {
            public void onReceive(Context context, Intent intent) {
                String action = intent.getAction();
                // device found
                if (BluetoothDevice.ACTION_FOUND.equals(action)) {
                    BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
                    // check if name matches
                    if (device.getName().equals(mBluetoothAdapter.getName())) {
                        // attempt to pair
                        device.createBond();
                    }
                }
            }
        };

        // register BroadcastReceiver
        IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND);
        registerReceiver(receiver, filter);
    }
}
