Map Recyclerview inside scrollview display black flickering background while scrolling

Question

I have used map view inside recyclerview row. I have attached screenshot. While scrolling maps display black flickering background.

Adapter code:

 @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        if (viewType == TASK_VIEW) {
            return new TasksViewHolder(LayoutInflater.from(parent.getContext())
                    .inflate(R.layout.item_task_row, parent, false));
        } else if (viewType == CHECKIN_VIEW) {
            return new CheckInViewHolder(LayoutInflater.from(parent.getContext())
                    .inflate(R.layout.item_checkin_row, parent, false));
        } else {
            return null;
        }
    }


@Override
private void onBindCheckInViewHolder(CheckInViewHolder holder, int position) {
    final JobCheckIn singleCheckIn = (JobCheckIn) items.get(position);
    holder.location.setText(singleCheckIn.getAddress());

    holder.lastUpdated.setText(String.valueOf("Created " +
            activity.getDateTime(singleCheckIn.getCreatedDateTime())));

    holder.deleteTask.setOnClickListener(view -> jobInterface.deleteCheckIn(singleCheckIn.getId()));

    float f = 0.0f;
    if (holder.mapView != null && Float.compare(singleCheckIn.getLatitude(), f) != 0 &&
            Float.compare(singleCheckIn.getLongitude(), f) != 0) {
        holder.mapView.setVisibility(View.VISIBLE);
        holder.initializeMapView();
        if (holder.gMap != null) {
            // The map is already ready to be used
            moveMap(holder.gMap, singleCheckIn.getLatitude(), singleCheckIn.getLongitude());
        }
    }

}
   public class CheckInViewHolder extends RecyclerView.ViewHolder implements OnMapReadyCallback {

    MapView mapView;

    GoogleMap gMap;


    public CheckInViewHolder(View view) {
        super(view);
        mapView = view.findViewById(R.id.checkInMapView);

    }


    @Override
    public void onMapReady(GoogleMap googleMap) {
        MapsInitializer.initialize(context);
        gMap = googleMap;
        googleMap.getUiSettings().setMapToolbarEnabled(false);
        if(items.get(getLayoutPosition())!=null )
            moveMap(gMap,((JobCheckIn) items.get(getLayoutPosition())).getLatitude(), ((JobCheckIn) items.get(getLayoutPosition())).getLongitude());
    }
    public void initializeMapView() {
        if (mapView != null) {
            // Initialise the MapView
            mapView.onCreate(null);
            // Set the map ready callback to receive the GoogleMap object
            mapView.getMapAsync(this);

        }
    }
}
 public void moveMap(GoogleMap gMap, double latitude, double longitude) {
    Log.v(TAG, "mapMoved: " + gMap);
    LatLng latlng = new LatLng(latitude, longitude);
    CameraUpdate cu = CameraUpdateFactory.newLatLngZoom(latlng, 6);
    gMap.addMarker(new MarkerOptions().position(latlng));
    gMap.moveCamera(cu);
}

I refer this link: Link but in this demo they used array adapter in my code we have used recyclerview adapter.

xml code:

 <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="150dp">

            <com.google.android.gms.maps.MapView
                android:id="@+id/checkInMapView"
                android:layout_width="0dp"
                android:layout_height="150dp"
                android:layout_weight="1"
                android:enabled="true"
                android:visibility="gone"
                map:cameraZoom="15"
                map:liteMode="true"
                map:mapType="normal" />

         <!--   I have also tried adding transparent view as below but still no solution.

        <View
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@android:color/transparent"/>-->

        </LinearLayout>

I am not performing any zoom-In, Zoom-out or drag. Thanks in advance.

Update

Previously i was initializing map in viewHolder instead of mentioned as above scenario.

 onBindCheckInViewHolder(...){
 holder.mapView.onCreate(null);
            holder.mapView.getMapAsync(googleMap -> {
                MapsInitializer.initialize(context);
                gMap = googleMap;
                googleMap.getUiSettings().setMapToolbarEnabled(false);
                moveMap(gMap, singleCheckIn.getLatitude(), singleCheckIn.getLongitude());
            });
      }

Write this line in AndroidManifest.xml:

android:hardwareAccelerated="true"

 <application
        android:name="com.xyz"
        android:allowBackup="true"
        android:hardwareAccelerated="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
</application>

It works.
