I would like to reshape those image to fit the button, so the ratio would possibly have to change. This is how my GUI looks right now. The images do not fit the buttons I tried several adjustments in my kv file, but right now I am stuck. This is my kv file.

由 情到浓时终转凉″ 提交于 2020-03-25 12:31:09
问题 I would like to populate MyData with information gathered from dropdown menus that show up in a popup window with "on_touch_up" in AddTouch. That data includes the position of "on_touch_up", in addition to the dropdown data. I am able to print the position within the AddTouch class, but I am having a hard time getting the data further down in my script using (for example: print('from MyMainApp: {}'.format(MyData.pos))).

1. Kivy 是什么？ 　 　 简单的说就是一个开源的库，这个库可以用来开发各种App。 　　 https://kivy.org/#home 2. Kivy能做什么？ 　　 3. 用Python写一个安卓app的基本流程 　　　 一：当然是下载安装Python 　　　二：确保安装的Python具备最新的 【 pip wheel setuptools virtualenv 】等模块。 　　　　　如果没有或者不是最新的到【 https://pypi.org/ 】下载最新的库安装。 　　　三：下载并安装kivy的依赖库 　　　　【 docutils pygments pypiwin32 kivy_deps . sdl2 == 0.1 . 22 kivy_deps . glew == 0.1 . 12 kivy_deps . gstreamer == 0.1 . 17 】， 　　　　　版本则需要根据自己的Python版本对应下载（直接pip在线安装较慢的话，可以使用IDM下载工具下载） 　　　四：安装Kivy，直接pip的方式安装或者下载到本地安装都没有问题。 　　　五： 确认电脑CPU已经开启虚拟化支持,否则可能会导入kivy失败； 　　　六 ：Python console 里面 import kivy 试下，确定Kivy及其支持库都安装成功， 　　　　　将官网的 例子
