标签在框中重叠而不是在滚动视图中环绕

Question

我有大量文本要以滚动视图的形式显示在屏幕上，因此我要字符串化以生成滚动视图，并添加一个gridlayout（或任何布局）以填充每个带有文本的标签。我的代码如下： KV：

ScrollView:
#The scrollview that the gridlayout filled with labels is added to.
            size_hint: 1, .8
            id: content_holder_kv

PY：

layout = GridLayout(cols=1, spacing=10, size_hint_y=None)
#The gridlayout that the labels will be added to and that will then be added to the scrollview.
layout.bind(minimum_height=layout.setter('height'))
for i in range(1141):
    temp = ("Long stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong string")
    line_of_text = Label(text=temp,text_size=(self.size))
    #This is the part ^ that I think is causing the issues. When I didnt have(text_size=(self.size)) the labels just went off the end of the screen. I have attempted adding text size as well as other attributes to try to get the wrapping behavior I need where the text label uses the entire width of the screen, is multiline, and doesnt overlap text with other labels in the scrollview but I have been unable to achieve this behavior.
    layout.add_widget(line_of_text)
self.content_holder_py.add_widget(layout)

一些我认为不重要的事情，但也许我想提一提，我的应用程序具有多个屏幕，并且由于要显示一本书的章节，所以我试图将行分开。文本行是本书中的句子/段落，我需要在不与其他文本标签重叠的情况下进行包装。下面是此代码产生的图片（尝试了其他布局设置选项，并且不确定导致该问题的原因）。

Answer 1

可以垂直增长但将文本以一定宽度包裹的标签：

<CustomLabel>:
    size_hint_y: None
    text_size: self.width, None
    height: self.texture_size[1]

要在X轴/水平方向和Y轴/垂直方向上滚动GridLayout，请将size_hint属性设置为（无，无）。

ScrollView - ScrollEffect, scroll_type，bar_width等

  

默认情况下，ScrollView允许同时在X和Y轴上滚动。通过将do_scroll_x或do_scroll_y属性设置为False，可以显式禁用在轴上滚动。

     

要在Y轴上/垂直滚动GridLayout，请设置子项的   宽度为ScrollView的宽度（size_hint_x = 1），然后将   将size_hint_y属性设置为“无”：

     

当滚动超出ScrollView的范围时，它将使用ScrollEffect处理超滚动。

     

scroll_type

     

设置用于滚动视图内容的滚动类型。   可用的选项包括：['内容']，['栏']，['栏'，'内容']

     

[“ bars”]可以通过拖动或滑动scoll栏来滚动内容。

main.py

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.label import Label
from kivy.properties import ObjectProperty


class CustomLabel(Label):
    pass


class RootWidget(BoxLayout):
    content_holder_py = ObjectProperty(None)

    def __init__(self, **kwargs):
        super(RootWidget, self).__init__(**kwargs)
        temp = "Long stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong stringLong string"

        for i in range(1141):
            line_of_text = CustomLabel(text=temp)
            self.content_holder_py.add_widget(line_of_text)


class TestApp(App):
    title = "Kivy ScrollView of Labels Demo"

    def build(self):
        return RootWidget()


if __name__ == "__main__":
    TestApp().run()

test.kv

#:kivy 1.11.0
#:import Window kivy.core.window.Window

<CustomLabel>:
    size_hint_y: None
    text_size: self.width, None
    height: self.texture_size[1]

<RootWidget>:
    orientation: "vertical"
    content_holder_py: content_holder_kv

    ScrollView:
        bar_width: 10
        bar_color: 0, 0, 1, 1   # blue
        bar_inactive_color: 1, 0, 0, 1   # red
        effect_cls: "ScrollEffect"
        scroll_type: ['bars']
        size_hint: (1, None)
        size: (Window.width, Window.height)

        GridLayout:
            id: content_holder_kv
            cols: 1
            spacing: 10
            size_hint_y: None
            height: self.minimum_height
