How to place the Floating Action Button exclusively on one fragment only in Tab layout

Question

I am trying to achieve the following with no success.I have two material design swipe tabs.I used this library 'com.oguzdev:CircularFloatingActionMenu:1.0.2' to achieve FAB but when i swipe the tab to the second tab,the FAB is still attached to the new fragment.

I would like to hide the FAB on the second Fragment. Is there a way to achieve this?

Here is what I did for a similar kind of problem. I declared a coordinator layout for the fragment. Inside that coordinator layout as you can see in the image i have declared a recyclerView that I use and below that i declared my floating action button.

After this I inflated the layout for floating action button in the onCreateView fragment method.

Here is my XML File Code:

<android.support.design.widget.CoordinatorLayout
android:id="@+id/main_content"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:focusableInTouchMode="true">

    <EditText
        android:id="@+id/search_string"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:layout_margin="5dp"
        android:layout_marginTop="50dp"
        android:hint="Search Keyword"
        android:drawableLeft="@drawable/search"
        android:gravity="left" >
    </EditText>

<android.support.v7.widget.RecyclerView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/photo_recycler_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="50dp"
    android:scrollbars="vertical"/>

<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="@dimen/fab_margin"
android:src="@drawable/ic_action_name6" />
</android.support.design.widget.CoordinatorLayout>

Here is my Java File Code:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_photo_list, container, false);

        FloatingActionButton fab = (FloatingActionButton) view.findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Photo photo = new Photo();
                PhotoLab.get(getActivity()).addPhoto(photo);
                Intent intent = PhotoPagerActivity.newIntent(getActivity(), photo.getId());
                startActivity(intent);
                /*Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();*/
                }
        });

        mSearchString=(EditText) view.findViewById(R.id.search_string);
        mPhotoRecyclerView = (RecyclerView) view.findViewById(R.id.photo_recycler_view);
        mPhotoRecyclerView.setLayoutManager(new GridLayoutManager(getActivity(), 3));

        updateUI();
        return view;
    }

It seems like this library assumes that you want to attach the FAB to your activity. The layout params that it generates also seems to assume that the parent is a FrameLayout. It is a little bit hacky, but you can detach it and reattach it where you want after you build() it.

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    FrameLayout root = (FrameLayout) inflater.inflate(R.layout.fragment_fab, container, false);

    FloatingActionButton actionButton = new FloatingActionButton.Builder(getActivity())
            .build();

    actionButton.detach();
    root.addView(actionButton);

    return root;
}
