如何用python

Question

如果没有.kv文件，如何在kivy中进行此布局？

基本上我想做的就是在同一列

中安装Button2和button3

from kivy.app import App
from kivy.uix.button import Button
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.textinput import TextInput


class TestApp(App):
def build(self):
    root = FloatLayout()
    layout = BoxLayout(orientation='vertical')
    button1 = TextInput(size_hint=(1,.7))
    button2 = TextInput(size_hint=(1,.2))
    button3 = Button(text='Send',size_hint=(1, .1))
    layout.add_widget(button1)
    layout.add_widget(button2)
    layout.add_widget(button3)
    root.add_widget(layout)
    return root

 TestApp().run()

Answer 1

将Button2和Button3添加到其他BoxLayout，然后将此BoxLayout添加为layout的子项。 在build方法中有类似的内容：

root = FloatLayout()
layout = BoxLayout(orientation='vertical')
layout1 = BoxLayout()
button1 = TextInput()
button2 = TextInput()
button3 = Button()
layout.add_widget(button1)
layout1.add_widget(button2)
layout1.add_widget(button3)
layout.add_widget(layout1)
root.add_widget(layout)

我假设这是你期望获得的行为：

Answer 2

要构建图像中的内容，您有4个按钮和两个框布局，一个嵌套在另一个内。您不应该需要大小提示，因为2行的高度相同，底部3个按钮的宽度相同。上图中不需要浮动布局。

class TestApp(App):
def build(self):
    # layout for the outer box layout to handle the rows
    layout = BoxLayout(orientation='vertical')
    # layout for the inner box layout, which is the bottom 3 columns
    bottom_row = BoxLayout(size_hint_y=0.6)  # Defaults to horizontal orientation

    # Make the buttons
    button1 = TextInput()    
    button2 = TextInput()
    button3 = Button()
    button4 = Button()

    # Add the first button and then bottom row to the layout. Add the bottom 3 buttons to the bottom_row box layout.
    layout.add_widget(button1)
    bottom_row.add_widget(button2)
    bottom_row.add_widget(button3)
    bottom_row.add_widget(button4)
    layout.add_widget(bottom_row)

return layout
