kivy：__ init __（）缺少x必需的位置参数

Question

我的课程电影如下：

class Movie(Widget):
    def __init__(self, title, image, time, description, trailer, fsk, threeD, **kwargs):
        super(Movie, self).__init__(title, image, time, description, trailer, fsk, threeD, **kwargs)
        title = StringProperty()
        image = StringProperty()
        time = StringProperty()
        description = StringProperty()
        trailer = StringProperty()
        fsk = NumericProperty()
        threeD = BooleanProperty()

当我运行我的脚本时，Python解释器会告诉我：

TypeError: __init__() missing 7 required positional arguments: 'title', 'image', 'time', 'description', 'trailer', 'fsk', and 'threeD'

那么我做错了什么？我已经有一段时间了。

与此问题相关的整个源代码：

class Movie(Widget):
    def __init__(self, title, image, time, description, trailer, fsk, threeD, **kwargs):
        super(Movie, self).__init__(title, image, time, description, trailer, fsk, threeD, **kwargs)
        title = StringProperty()
        image = StringProperty()
        time = StringProperty()
        description = StringProperty()
        trailer = StringProperty()
        fsk = NumericProperty()
        threeD = BooleanProperty()

class MainView(Widget):
    def __init__(self, **kwargs):
        super(MainView, self).__init__(**kwargs)
        movies = ListProperty()
        # movies = self.getMovies()
        # for movie in movies:
        #   self.add_widget(movie)

    def getMovies(self, url="http://.../"):
        html = lxml.html.parse(url)
        titles = html.xpath("//h5")
        times = html.xpath("//td[@class='pday ptoday']/span/a")
        trailers = html.xpath("//a[@data-modal-trailer-url]/@data-modal-trailer-url")
        fsks = html.xpath("//tr[@data-fsk]/@data-fsk")
        movies = list()
        # for i in range(0, len(titles)):
        #   movie = Movie(titles[i].text, "images[i]", times[i].text, "", "https:" + trailers[i][:-11], fsks[i], "no")
        #   movies.append(movie)
        return movies

Answer 1

我发现kv-lang文件是导致此对象初始化错误的原因。所以我不知道如何修复它，但我认为这是另一个问题，因为这是为什么__init__被称为
