[Android][MenuItem]How to display title text when long press actionLayout?

Question

I'm using MenuItem in my tool bar and some of the items require custom layouts, so I created actionLayout for them.
The UI looks fine, but when I long press the items that only have icon but no actionLayout, they'll show title as a toast below the icon, while those have actionLayout won't show anything.
I want all items have same behavior that will show their title at the same place(below the icon) during long pressing.

• MenuItem without custom layout:

     <item
        android:id="@+id/normal_item"
        android:title="@string/title"
        android:icon="@drawable/icon"
        app:showAsAction="ifRoom"
        />

• MenuItem with custom layout:

     <item
        android:id="@+id/custom_item"
        android:title="@string/title"
        android:icon="@drawable/icon"
        app:actionLayout="@layout/layout"
        app:showAsAction="ifRoom"
        />

btw, the item with actionLayout was unclickable so I set an onClickListener in onCreateOptionsMenu and it worked:

    @CallSuper
        override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
            inflater.inflate(R.menu.myMenu, menu)
            menu.findItem(R.id.custom_item).actionView?.setOnClickListener {
                // do something
            }
        }    

It's easy to also set a LongClickListener to the actionView, but how to make it show the title text like this? (image source: http://www.devexchanges.info/2017/01/android-tip-detecting-long-click-at.html):

Solved this by simply using:

TooltipCompat.setTooltipText(myActionView, titleString).
