How do I pass a Custom Object to a list in a different fragment?

Question

So I have my MainActivity which has a BottomNavigationView , in there I have 3 different tabs which redirects me to 3 different fragments when I click them.

In FragmentA I have a RecyclerView with items, each item has a button. When I click said button I want to send that object over to FragmentB so I can add it to the ArrayList<CustomObject> and update the RecyclerView in FragmentB to display that item.

The only issue is that I don't know how to send that object over on my button click.

adapter.setOnItemRemoveListener(new RemoveItemAdapter.OnItemRemoveListener() {
    @Override
    public void onItemRemove(int position) {
        //Do I send it from here?

    }
});

First of all implements Parcelable in your Model(Object) class and then from your Fragment A just call this -

Fragment fragmentA = new FragmentGet();
Bundle bundle = new Bundle();
bundle.putParcelable("CustomObject", customObject);
fragmentA .setArguments(bundle);

Also, in Fragment B you need to get the Arguments too -

Bundle bundle = getActivity().getArguments();
if (bundle != null) {
    model = bundle.getParcelable("CustomObject");
}

Your custom object class will look like this -

public class CustomObject implements Parcelable {

    private String name;
    private String description;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(this.name);
        dest.writeString(this.description);
    }

    public CustomObject() {
    }

    protected CustomObject(Parcel in) {
        this.name = in.readString();
        this.description = in.readString();
    }

    public static final Parcelable.Creator<CustomObject> CREATOR = new Parcelable.Creator<CustomObject>() {
        @Override
        public CustomObject createFromParcel(Parcel source) {
            return new CustomObject(source);
        }

        @Override
        public CustomObject[] newArray(int size) {
            return new CustomObject[size];
        }
    };
}

Just call the Fragment B from your recycler view item click listener and use the above mentioned code to pass the Custom Object using Parcelable.

Hope it helps.
