kivy

问题 Anyone know how to use kivy? I installed it on my window7, python2.7.

问题 I'm trying to run a simple Kivy testapp on Android, but I'm having problems getting Buildozer to build and push the APK to my phone. I'm running it inside a Linux (Ubuntu 64-bit) virtual machine; my host machine runs Windows 10. I have installed all prerequisites that I know of: zlib1g-dev, cython, openjdk-8-jdk, git, pip. I'm trying to run "buildozer android debug deploy run" as per the Kivy documentation's instructions and it seems like Buildozer gets pretty far into the process, but

问题 I'm having trouble with the threading in Python and Kivy. I'm trying to implement threading in my kivy app. Basically, when I click a button and the screen switches to the next one, I want to launch a thread, and when I click the 'back' button, the thread should stop. It's a pretty simple task, but my current code doesn't end the thread once I pressed 'back'. Here is my code. I'm only including the necessary parts: KV: <MenuScreen>: canvas.before: Rectangle: pos: self.pos size: self.size

问题 I am new to kivy and I was able to finally finish my project and compile it into a single executable using pyinstaller and its spec file. If I try to launch it on a machine with no kivy or python installation it always fails with this error (Below). I have looked and researched amny articles but most of them assume that kivy or the path of the missing png or gstreamer to be in the PATH but my machines where I am trying to launch does not have python or kivy. Can someone please help me here?

问题 Currently I am trying to build an App that I wrote in Python and Kivy via buildozer. Whatever I am doing, I am running into problems with window_x11. Even if I comment all the windows related things out in the code or doing all the things described in this post. Here is a part of the error generated: x11 - ImportError: No module named 'kivy.core.window.window_x11' Another strange aspect is that I am using Python-3.x, but it keeps on saying about python-2.7. running cython ./kivy/core/window
