设置 text_input 的值，所以它仍然是默认的 None 。只是设置一个ID不会设置该属性。这里有几个简单的修复。
首先，您可以填写该值：
< OptionMenu>：
＃设置text_input属性为
下面的text_input id的值
text_input：text_input
。 ..
TextInput：
id：text_input
...
或者，您可以通过 ids 集合来访问该小部件，并完全删除 text_input 属性：
$ b $
def load（self，path，filename）：
with open（os.path.join（path，filename [0]） ）作为流：
＃self.ids是这个小部件规则的id的集合
self.ids.text_input.text = stream.read（）
self.dismiss_popup（）
Keep running into a error that says "Attribute Error: 'None Type' object has no attribute 'text'. I have no idea where the problem is. Did a fair amount of research, but saw no posts that provided any clarity on the issue. Thoughts?

You never set the value of text_input, so it is still the default None. Just setting an id doesn't set that attribute. There are a couple easy fixes here.
First, you can fill in that value:
<OptionMenu>:
# this sets the `text_input` attribute to the value
# of the `text_input` id below
text_input: text_input
...
TextInput:
id: text_input
...
Alternatively, you can access the widget via the ids collection, and remove the text_input attribute completely:
def load(self, path, filename):
with open(os.path.join(path, filename[0])) as stream:
# self.ids is the collection of ids for this widget rule
self.ids.text_input.text = stream.read()
self.dismiss_popup()
