I want set gravity to right when horizontal recyclerview has only one row,
because when horizontal recyclerview has more one row it gravity set to right
,How can i do it?

In your RecyclerViewDataAdapter ,set the last parameter of the setLayotManager to false and if that does not work , set LinearLayoutManager.setStatckFromEnd property to true

How to remove the last item in recyclerview adapter by a button?

I have a recyclerview and I want to delete the last item on it when I click a button that is not in the recyclerview. I want to delete the item and notify the adapter that the item is deleted so I can enter another item. By the way, the items I enter are by edittext and a button.

this.personName = personName;
}
}
I expect to delete the last item (integer) in the recyclerview and notify the adapter so I can edit the value when needed.

You can add a method in your adapter to remove last item in the list:
public ViewHolder removeLastItem() {
if (personUtils == null || personUtils.isEmpty()) return;
personUtils.removeAt(personUtils.getSize()-1);
notifyDataSetChanged();
}
When the button is clicked, just call:
adapter.removeLastItem()

Check if you are in the last index, then remove the item and use notifyItemRemoved to notify any registered observers:
if(currentPosition == 0){
listOfItems.removeAt(currentPosition)
notifyItemRemoved(currentPosition)
}

Expandable layout Expands upwards instead of downwards

When i try to put my Expandable layout to the bottom of my cardview using
android:layout_gravity="bottom" it goes to the bottom but expands upwards
After clicking the relative layout "button"
I am getting data from arraylist passing it to the recyclerview and cardview
i don't know if it's because of the Adapter animation settings or just fomr the xml

Replace the below
InviteUsersListRow rowUser = new InviteUsersListRow(R.id.profileImage, R.id.imageButtonInviteUser, name, mobile);
with
InviteUsersListRow rowUser = new InviteUsersListRow(R.drawable.camera, R.drawable.add_user_50, name, mobile);
The pic should be from "R.drawable" not from "R.id"
You should actually set an image resource below and not an id
holder.imageView.setImageResource(rowItem.getImageId());
holder.imgStatus.setImageResource(rowItem.getImageStatus());
In the above code you are not setting a drawable item.
