Appium gets the exception of displaying spaces in the middle of object text through XPath

appium, Why can't we find the correct element

//android.view.View[@content-desc=" Show menu All "]

Print all types of objects on the page to by looping List

So you can see

a = self.find_elements(*show_all_button2)
text = FindText(self.driver).find_text('//android.view.View')
L= []
for i in a:
text = i.get_attribute("contentDescription")
L.append(text)
print(L)

  Print the results ：

[None,' Show menu \n All ']
