Print name of the list while using KivyMDList

Question

I am developing an application that shows movie info. But a problem has arisen; how to find out which item of the mdlist has been clicked? E.g: if I clicked a movie name in the list: joker, it should open a new screen with a name joker.

You just need to add an on_press or on_release to each OneLineListItem. Here is a modified hlo() method that does that:

def hlo(self):
    self.helper.current='show'
    ia = imdb.IMDb()
    name = self.helper.get_screen('searchs').ids.wow.text
    search = ia.search_movie(name)
    self.no=0
    self.j=0
    for self.i in search:
       self.helper.get_screen('show').ids.container.add_widget(OneLineListItem(text=str(self.i), on_release=self.item_pressed))

def item_pressed(self, item):
    print('item_pressed:', item.text)
