Android 标记点击并不总是被识别

我已经在我的应用程序中加入了谷歌地图，并使用for循环在地图中添加了4个标记。我还设法通过使用地理编码器获得了这些添加标记的邮政编码、城市名称和地址

这一切都是可行的，但问题是点击标记并不总是有效。有时我必须双击才能看到标记的标题。我真的不知道为什么。这是我的全部代码

     public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;
    String city, adress, zip;
    Marker marker;
    LatLngBounds.Builder builder = new LatLngBounds.Builder();

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

        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(map);
        mapFragment.getMapAsync(this);
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;    

        LatLng[] point_new = new LatLng[4];
        point_new[0] = new LatLng(52.4788535, 13.32730760000004);
        point_new[1] = new LatLng(52.4794297, 13.313520799999992);
        point_new[2] = new LatLng(52.5272885, 13.458033200000045);
        point_new[3] = new LatLng(52.52603999999999, 13.488159999999993);

        for (int i = 0; i < point_new.length; i++) {
            drawMarker(point_new[i]);

                  marker = mMap.addMarker(new MarkerOptions().position(point_new[i]));

           mMap.moveCamera(CameraUpdateFactory.newLatLng(point_new[i]));


        }
        getAdress(52.4788535, 13.32730760000004 );
        marker = mMap.addMarker(new MarkerOptions().position(point_new[0]).title(adress+"," + zip + "" + city));

        getAdress(52.4794297, 13.313520799999992);
        marker = mMap.addMarker(new MarkerOptions().position(point_new[1]).title(adress+"," + zip + "" + city));

        getAdress(52.5272885, 13.458033200000045);
        marker = mMap.addMarker(new MarkerOptions().position(point_new[2]).title(adress+"," + zip + "" + city));

        getAdress(52.52603999999999, 13.488159999999993);
         marker = mMap.addMarker(new MarkerOptions().position(point_new[3]).title(adress+"," + zip + "" + city));

        for (int j = 0; j < point_new.length; j++) {
            builder.include(point_new[j]);    
        }


        LatLngBounds bounds = builder.build();
        mMap.animateCamera(CameraUpdateFactory.newLatLngBounds(bounds, 20));

    }


    public void drawMarker(LatLng point) {
        // Creating an instance of MarkerOptions
        MarkerOptions markerOptions = new MarkerOptions();

        // Setting latitude and longitude for the marker
        markerOptions.position(point);

        // Adding marker on the Google Map
        mMap.addMarker(markerOptions);
    }

    public void getAdress(double lat, double lng){
        Geocoder geocoder = new Geocoder(MapsActivity.this, Locale.getDefault());

        List<Address> addresses  = null;
        try {

            addresses = geocoder.getFromLocation(lat,lng,1);

        } catch (IOException e) {
            e.printStackTrace();
        }

        city = addresses.get(0).getLocality();
         adress = addresses.get(0).getAddressLine(0);
         zip = addresses.get(0).getPostalCode();
    }
}

试试这个代码，我已经测试过了，它可以工作了

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }


    /**
     * Manipulates the map once available.
     * This callback is triggered when the map is ready to be used.
     * This is where we can add markers or lines, add listeners or move the camera. In this case,
     * we just add a marker near Sydney, Australia.
     * If Google Play services is not installed on the device, the user will be prompted to install
