问题描述

您好，我在使用 kivy 的 textinput 小部件的 input_type 属性时遇到问题.问题是我做了两个自定义文本输入，一个称为 StrText，我在其中设置 input_type = 'text'.然后是第二个名为 NumText 的文本输入，input_type = 'number'.我使用 kivy 启动器在我的手机上对此进行了测试，并注意到一旦我点击 NumText 输入，它会带来一个数字键盘，如果我点击 StrText，它会带来相同的数字键盘而不是普通的文本键盘.如果你稍微玩一下，你会发现大部分时间都会返回数字键盘.请问我的代码有问题吗，或者我该如何解决?你会在下面找到我的代码

Hi im having issues with using the input_type property of kivy's textinput widget. The thing is i made two custom text input one i called StrText where i set input_type = 'text'. Then a second text input named NumText with input_type = 'number'. I tested this on my phone using kivy launcher, and noticed that once i tap on the NumText input and it brings a number keyboard, if i tap on the StrText, it brings the same number keyboard instead of a normal text keyboard. If you play with it a little you'll notice mostly number key board is returned most of the time. Please is there something wrong with my code, or how can i fix this? You'll find my code below

main.py

from kivy.app import App
from kivy.uix.bubble import Bubble
from kivy.core.window import Window

class  BubbleApp(App):
    pass

if __name__ == '__main__':
    Window.fullscreen = False
    BubbleApp().run()

bubble.kv 

GridLayout:
    cols: 1
    StrText:
        height: '48dp'
        size_hint_y: None

    Label:
        text: 'Number keyboard below'
        height: '48dp'
        size_hint_y: None
        multiline: False
        font_size: self.height * .5

    NumText:
        height: '48dp'
        size_hint_y: None


<StrText@TextInput>:
    input_type: 'text'
    multiline: False
    font_size: self.height * .5

<NumText@TextInput>:
    input_type: 'number'
    input_filter: 'int'
    multiline: False
    font_size: self.height *.5

解决方案

最近我在使用 Kivy1.10.0 构建我的应用程序时遇到了类似的问题.我在 android 中使用了默认的键盘应用程序，但它仍然不断地从 Numeric Keypad 更改为 Text Keypad.

Recently I faced similar issue when I built my App using Kivy1.10.0. I used the default keyboard app in android but still it was keep changing from Numeric Keypad to Text Keypad.

这次我尝试使用 kivy==1.9.1 和 Cython==0.23.1 和 buildozer==0.32 来构建 .apk，它对我有用.

This time I tried kivy==1.9.1 with Cython==0.23.1 and buildozer==0.32 to build the .apk and it worked for me.

注意:

我建议创建一个 virtualenv 来安装上面的特定包并使用它来创建 .apk 文件.

I suggest to create a virtualenv to install above specific packages and use it to create the .apk file.

virtualenv build32env
source build32env/bin/activate
pip install buildozer==0.32 Cython==0.23.1

执行 buildozer init 后，确保更改 buildozer.spec 文件:

After executing buildozer init make sure to change buildozer.spec file:

来自

requirements = kivy

到

requirements = kivy==1.9.1

否则它将使用最新的 kivy 版本来构建 .apk 文件.

otherwise it will use the latest kivy version to build the .apk file.

希望对他人有所帮助！
