Android Tooltips on MenuItem

I'm trying to show a tooltip on a MenuItem.

I'm using this library: compile 'com.github.xizzhu:simple-tool-tip:0.5.0' from this Maven repository: maven { url "https://jitpack.io" }. I'm getting the view for the MenuItem, to use it as an anchor for the ToolTip but it is launching a nullPointerException in the toolTipView.show() method. When I debug the app, the View item is correct. If i replace the View item with the floating button fab, it works perfectly.

At some point, it worked, but the ToolTip position was wrong, it appears on the left top corner of the screen, instead of the right position, which would be at bottom of View item.

Note: I'm creating the ToolTip inside OnCreateOptionsMenu() because OnViewCreated() run before this method, so I have to do it there.

Here is where it happens, if you need any other piece of code I can upload it.

Menu:

<menu
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tooltipproto="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/action_settings"
        tooltipproto:actionViewClass="android.widget.ImageButton"
        android:title="@string/action_settings"
        tooltipproto:showAsAction="always" />

</menu>

Fragment:

package com.tooltipproto;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v4.app.Fragment;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;

import com.github.xizzhu.simpletooltip.ToolTip;
import com.github.xizzhu.simpletooltip.ToolTipView;

public class ShowFragment extends Fragment{

    View item;
    FloatingActionButton fab;

    public ShowFragment(){
    }

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        super.onCreateOptionsMenu(menu, inflater);
        inflater.inflate(R.menu.menu_main, menu);
        MenuItem menuItem = menu.findItem(R.id.action_settings);
        item = menuItem.getActionView();

        ToolTip toolTip = new ToolTip.Builder()
                .withText("Simple Tool Tip!")
                .withTextSize(50)
                .withPadding(10,10,10,10)
                .withCornerRadius(10)
                .build();
        final ToolTipView toolTipView = new ToolTipView.Builder(getActivity())
                .withAnchor(item)
                .withToolTip(toolTip)
                .withGravity(Gravity.BOTTOM)
                .build();
        toolTipView.show();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {
        // Defines the xml file for the fragment
        setHasOptionsMenu(true);
        fab = (FloatingActionButton) getActivity().findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });
        setHasOptionsMenu(true);
        return inflater.inflate(R.layout.fragment, parent, false);
    }


}
