我一直在寻找相同的解决方案并找到了这个解决方案，它适用于我的 SearchView。查看(Kotlin 版本):

override fun onCreateOptionsMenu(menu: Menu?): Boolean {
        menuInflater.inflate(R.menu.menu_main, menu)
        val search: SearchView =
            menu!!.findItem(R.id.action_search_main).actionView as SearchView
        search.apply {
            imeOptions = EditorInfo.IME_ACTION_DONE
            isSubmitButtonEnabled = true
            setOnQueryTextListener(object : SearchView.OnQueryTextListener {
                override fun onQueryTextSubmit(p0: String?): Boolean {
                    return false
                }

                override fun onQueryTextChange(p0: String?): Boolean {
                    // My Function
                    return false
                }
            })
        }
        val menuItemSearch = menu.findItem(R.id.action_search_main)
        menuItemSearch.setOnActionExpandListener(object : MenuItem.OnActionExpandListener {
            override fun onMenuItemActionExpand(item: MenuItem?): Boolean {
                Log.wtf("FAB", "HIDE")
                fab.hide()
                return true
            }

            override fun onMenuItemActionCollapse(item: MenuItem?): Boolean {
                Log.wtf("FAB", "SHOW")
                fab.show()
                return true
            }
        })

        return super.onCreateOptionsMenu(menu)
    }
