有没有一种方法可以使用Kivy和Python在TextInput字段中显示数字键盘(最好带有气泡)?带代码的新问题 [英] Is there a way to show a number pad (preferably with a bubble) in a TextInput field using Kivy and Python? NEW ISSUE WITH CODE
问题描述
我有一个应用程序，您在其中输入数字(很多)，并且键盘也很难是字母，我希望它只是数字(0-9)和一个点.有什么方法可以使用Kivy的.kv文件和Python做到这一点?我已经在.kv文件中尝试过input_type: 'number'，但是无法正常工作.谢谢！
I have an app where you input numbers (a lot) and it gets hard that the keyboard is also letters, I would like it to be just numbers (0-9), and a dot. Is there any way to do this using Kivy's .kv file and Python? I have tried input_type: 'number' in the .kv file, but I couldn't get it to work. Thanks!
修改: 我也尝试过使用泡沫，没有运气.不过，如果可能的话，最好有一个泡泡数字键盘.
I have also tried using bubbles, no luck. Although, it would be nice to have a bubble number pad if possible.
修改2: 我在这个问题上给予了另一个赏金，因为当我将VKeyboard放置在物理设备上(以及弹出窗口)时，它会中断.具体来说，VKeyboard不会显示(并且转到另一个TextInput字段后也会崩溃)，并且我的弹出窗口无法正确缩放.我的logcat如下所示.
Edit 2: I have put another bounty on this question because when I put the VKeyboard on a physical device (along with a popup) it breaks. In specific, the VKeyboard wont show up (and it also crashes after going to another TextInput field) and my popup doesn't scale correctly. My logcat is shown below.

修改3: 感谢 Fadi Abu Raid ，我得以弄清弹出问题.现在，我希望增加VKeyboard的尺寸，因为它在手机上非常小.我发现此发布，但没有找到任何帮助.
Edit 3: Thanks to Fadi Abu Raid, I was able to figure out the Pop-Up issue. Right now, I am looking to increase the size of the VKeyboard as it is very small on a phone. I found this post, but I did not find any help from it.
推荐答案
我已使用以下示例完成此操作:
I have done it using this example:
https://github.com/kivy/kivy/tree/master /examples/键盘
您的.kv文件应该是这样的:
Your .kv file it should be like this:
TextInput:
input_type: 'number'
on_focus: root.text_focused()
您应该有一种方法可以在Python文件中使用数字布局调用键盘.
And you should have a method to call the keyboard with numeric layout in your Python file.
from kivy.uix.vkeyboard import VKeyboard
def text_focused(self):
VKeyboard.layout = 'numeric.json'
player = VKeyboard()
从上面的链接获取布局，并将其与脚本保存在同一文件夹中.
Get the layout from the link above and save it in the same folder with your script.
输出应如下所示:
更新
在发布此内容后，我在此处找到了更好的解决方案.
After posting this I have found a better solution here.
但是它缺少我添加的一些功能:
However it lacks some features that I have added :
- 添加删除按钮.
- 气泡键盘外的触摸使其消失.
- 删除一些不必要的代码.
- 允许使用光标位置删除
您需要从在此处并将字体与main.py脚本放置在同一文件夹中，以便能够在小键盘上显示删除符号.
You need to download arial-unicode-ms.ttf font from here and place the font in the same folder as your main.py script to be able to display the delete symbol on the keypad.
main.py
from kivy.app import App
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.bubble import Bubble, BubbleButton
from kivy.lang import Builder
from kivy.core.window import Window
class CustomBubbleButton(BubbleButton):

app.root.text_input.cursor=(index+2,0)
else:
app.root.text_input.text=app.root.text_input.text[:index] + app.root.text_input.text[index+1:]
app.root.text_input.cursor=(index,0)
pass
class NumericKeyboard(Bubble):
def on_touch_up(self, touch):
app= App.get_running_app()
if not self.collide_point(*touch.pos) and not app.root.text_input.collide_point(*touch.pos):
app.root.remove_widget(app.root.bubb)
app.root.text_input.focus=False
delattr(app.root, 'bubb')
def __init__(self, **kwargs):
super(NumericKeyboard, self).__init__(**kwargs)
self.create_bubble_button()
def create_bubble_button(self):
numeric_keypad = ['7', '8', '9', '4', '5', '6', '1', '2', '3', '.', '0', '⌫']
for x in numeric_keypad:
bubb_btn = CustomBubbleButton(text=str(x),font_name='arial-unicode-ms.ttf')
self.layout.add_widget(bubb_btn)

def show_bubble(self, *l):
