在Android中，将“altBeacon: didEnterRegion”改为“altBeacon: 进入区域”。修改时，需要先引用altBeacon库，然后在代码中实现以下语句:

public class MainActivity extends AppCompatActivity implements BeaconConsumer, MonitoringListener {

    private BeaconManager beaconManager;

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

        beaconManager = BeaconManager.getInstanceForApplication(this);
        beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout(BeaconParser.EDDYSTONE_UID_LAYOUT));
        beaconManager.addMonitoringListener(this);

        try {
            Identifier myBeaconNamespaceId = Identifier.parse("0x2f234454f4911ba9ffa6");
            Identifier myBeaconInstanceId = Identifier.parse("0x000000000001");
            Region myBeaconRegion = new Region("myBeaconRegion", myBeaconNamespaceId, myBeaconInstanceId, null);
            beaconManager.startMonitoringBeaconsInRegion(myBeaconRegion);
        } catch (RemoteException e) {
            e.printStackTrace();
        }

        beaconManager.bind(this);

    }

    @Override
    public void onBeaconServiceConnect() {
        beaconManager.addMonitorNotifier(new MonitorNotifier() {
            @Override
            public void didEnterRegion(Region region) {
                Log.d("BeaconsActivity", "I just saw an AltBeacon for the first time!");
            }

            @Override
            public void didExitRegion(Region region) {
                Log.d("BeaconsActivity", "I no longer see an AltBeacon");
            }

            @Override
            public void didDetermineStateForRegion(int state, Region region) {

            }
        });
    }

    @Override
    public Context getApplicationContext() {
        return this;
    }

    @Override
    public void unbindService(ServiceConnection serviceConnection) {
        unbindService(serviceConnection);
    }

    @Override
    public boolean bindService(Intent intent, ServiceConnection serviceConnection, int i) {
        return bindService(intent, serviceConnection, i);
    }

    @Override
    public void onPointerCaptureChanged(boolean hasCapture) {

    }

    @Override
