Bug in recycle grid. Changing UI without click randomly

I have a recycler inside fragment in view pager.
The problem that it put likes on user accounts in UI randomly but in DB everything is fine.
In logs, I see that random is not influence on BD. So the bug is only in UI part. After the refresh of the list, it can appear again and after that disappear.
I would like to share code but I already don't have an I idea where the problem could be. It might be in adapter/refresh list listener / XML or any other places. Please let me know what part of the code you need and I will provide it. Maybe it is a bug of recycler as itself and I can't fix it.

Override this two methods inside your adapter
#Override
public long getItemId(int position) {
return position;

#Override

Expanding Listview using Recyclerview inside Scrollview

I tried below code to implement an expend and collapse content using recyclerview(listview) a link
final boolean isExpanded = position==mExpandedPosition;
holder.details.setVisibility(isExpanded?View.VISIBLE:View.GONE);
holder.itemView.setActivated(isExpanded);
if (isExpanded)
previousExpandedPosition = position;
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mExpandedPosition = isExpanded ? -1:position;
notifyItemChanged(previousExpandedPosition);
notifyItemChanged(position);
}
});
In my case when i click the particular position in recyclerview its expanding but it goes above the recyclerview.I cant see the full expanded content.i can see only partial content.In this case i need to scroll the recyclerview to view the full content.But i am searching for a solution to view the content without scroll the recyclerview. If i click another position in recyclerview that should be placed over an recyclerview.

recyclerView.setNestedScrollingEnabled(false);

I am using vector images generated from Android Studio but those images are not displayed in recyclerView.
What should i do? Let me mention that the vector images that i use inside recyclerView are properly displayed if i use them in simple image views.

MapView inside RecyclerView only displaying map on clicks

This has to be the most absurd thing ever.
I have a RecyclerView with repeated custom items. Inside these items, there are a few textfields, buttons and a single MapView.
The issue is that when the list loads, the MapView only displays the Google logo and no other tile or detail (or marker). However, when I tap once on the map, it shows the marker I added. On the next tap, it loads a pixellated map. On another tap, it loads a better quality map. On further clicks it adds the text labels for nearby locations. LatLngBounds are also not working but that's a secondary problem.
Why is this happening?
My code is as follows:
JobAdapter.java
public class JobAdapter extends RecyclerView.Adapter<JobAdapter.ViewHolder>
{
private Context context;
private static List<Job> jobList;
private HashSet<MapView> mapViews = new HashSet<>();
private GoogleMap googleMap;
public JobAdapter(Context con, List<Job> jobs)
{
context = con;
jobList = jobs;
}
#Override
public int getItemCount()
{
return jobList.size();
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
{
Context context = parent.getContext();
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.listitem_booking, parent, false);
ViewHolder viewHolder = new ViewHolder(view);
mapViews.add(viewHolder.mapView);
return viewHolder;
}
#Override
public void onBindViewHolder(ViewHolder holder, int position)
{
Job job = jobList.get(position);
holder.mapView.setClickable(false);
if(job.getJobType().equalsIgnoreCase("Now"))
{
holder.pickup.setBackgroundColor(ContextCompat.getColor(context, R.color.lightRed));
}
holder.pickup.setText(job.getPickupAddress());
if(job.getDestinationAddress() != null && !job.getDestinationAddress().equalsIgnoreCase(""))
{
holder.destination.setText(job.getDestinationAddress());
}
else
{
holder.destination.setVisibility(View.GONE);
}
holder.person.setText(job.getContact());
holder.datetime.setText(job.getDate() + " at " + job.getTime());
}

}

{

boolean hasDestination = true;
String[] destinationLatlng = null;

if(job.getDestinationAddress() == null || job.getDestinationAddress().equalsIgnoreCase(""))
{

}
else
{
destinationLatlng = job.getDestinationLatLong().split(",");
destination = new LatLng(Double.valueOf(destinationLatlng[0]), Double.parseDouble(destinationLatlng[1]));
}
final String[] pickupLatlng = job.getPickupLatLong().split(",");
final LatLng pickup = new LatLng(Double.valueOf(pickupLatlng[0]), Double.parseDouble(pickupLatlng[1]));
if(hasDestination)
{
googleMap.addMarker(new MarkerOptions()
.position(pickup)
.title(job.getPickupAddress()));
googleMap.addMarker(new MarkerOptions()
.position(destination)
.title(job.getDestinationAddress()));
LatLngBounds.Builder builder = new LatLngBounds.Builder();
builder.include(pickup);
builder.include(destination);
LatLngBounds bounds = builder.build();
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngBounds(bounds, 5);
googleMap.animateCamera(cameraUpdate);
}

I've tried various things but nothing seems to be working.

Try adding onResume, like this:
mapView.onCreate(null);
mapView.getMapAsync(this);
mapView.onResume();
Edit:
I've just noticed you are using
map:liteMode="true"
Try removing it (at least to test) or adding the following to the xml:
map:cameraZoom="15"
map:mapType="normal"
Either way, I think the onResume is needed.
When I use liteMode it sometimes takes a few seconds (about 5) for the map to show after the logo.

There might another issue in your code. The "map" should be:
xmlns:map="http://schemas.android.com/apk/res-auto"
but not:
xmlns:map="http://schemas.android.com/tools"

Android Recyclerview on swipe layout leave white space

I am implementing recyclerview with swipe layout from right side using this. I have hide one of the child view in adapteron first position as you can see but problem is that once it hide successfully, blank white space show while swiping from right side.
Below is my adapter view.xml. Below I have attached image in which you can see the exact problem.
