在 Recycleview Kivy 中显示不同的小部件类型

Question

我想知道是否可以在 kivy recycleview 中显示不同的小部件类型，我让它显示文本框，这很好，但可以在同一个回收视图中显示图像，还是我必须在顶部创建另一个 recycleview我现有的，这是我的代码和当前的应用程序快照，我目前的理解是你只能在回收视图中有一个视图类，我的是文本输入，那么如何将另一个视图类添加到同一个回收视图。

您可以定义自己的viewclass 来显示您想要的任何内容。您的viewclass 必须具有与RecycleView 的data 中的键相对应的Properties。

这是一个简单的例子：

from kivy.app import App
from kivy.lang import Builder
from kivy.uix.recycleview import RecycleView


class RV(RecycleView):
    def __init__(self, **kwargs):
        super(RV, self).__init__(**kwargs)

        # set up the data
        self.data = [
            {'text': 'Some Text', 'image': 'dots.png'},
            {'text': 'more text', 'image': 'tester.png'}
            ]

kv = '''
<MyViewClass@BoxLayout>:
    # define the properties that appear in the data
    text: ''
    image: ''
    
    # define how the data is displayed
    Image:
        source: root.image
    Label:
        text: root.text
RV:
    viewclass: 'MyViewClass'
    RecycleBoxLayout:
        padding: 10, 0, 10, 0
        size_hint_y: None
        height: self.minimum_height
        default_size: None, 40
        default_size_hint: 1, None
        orientation: 'vertical'
        spacing: 3
'''

class TestApp(App):
    def build(self):
        return Builder.load_string(kv)

TestApp().run()
