Java 标记id在设置标记实例时更改

我正在使用谷歌地图和标记来显示一些关于照片拍摄地点的信息和其他相关信息

所以基本上我有一个活动，我有一个与特定植物相关的照片列表，在活动中我可以选择在地图上看到它。当我按下该选项时，所有照片（有位置）在地图上显示为绿色标记，当前单击的照片显示为黄色标记

因此，当我点击“查看地图”时，我会传递我所有照片的数组、选定的照片id以及用户的当前位置

像这样：

 public void showMap(View view){
        Intent i = new Intent(this,MapsActivity.class);
        i.putExtra("currentLat",location.getLatitude());
        i.putExtra("currentLon",location.getLongitude());
        i.putExtra("positionCurr",pos);
        Bundle bundle = new Bundle();
        bundle.putSerializable("key", photos);
        i.putExtras(bundle);
        startActivity(i);
    }

public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;
        Marker marker;
        LatLng currentZone = null;
        LatLng plantLocation = null;

        Double currentLat = getIntent().getDoubleExtra("currentLat", 0);
        Double currentLon = getIntent().getDoubleExtra("currentLon", 0);
        int currentPlantId = getIntent().getIntExtra("positionCurr",-1);

        allPhotos.setOnClickListener(new View.OnClickListener() {
            int count = 0;
            @Override

                count++;
                if(count == positions.size() - 1){
                    count = 0;
                }
                mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(plantPos, 35));
            }
        });

            mMap.addMarker(new MarkerOptions().position(currentZone).title("Marker in Portugal"));
            mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(currentZone, 15));
            found = true;
        }

        BitmapDescriptor bitmapDescriptor;

        LatLng latLng;

            ImageView image = (ImageView)view.findViewById(R.id.imageView1);

然后在地图活动中，我对它们进行如下初始化：

 public void showMap(View view){

    }
