Looks like at least part of this has been addressed in a recent update to p4a: https://github.com/kivy/python-for-android/pull/2692

You may find using input_filter simpler that overloading insert_text.
Assuming you wanted to only allow letter inputs, you could do as below:
from kivymd.app import MDApp
from kivymd.uix.button import MDFlatButton
from kivymd.uix.floatlayout import MDFloatLayout
from kivymd.uix.textfield import MDTextField
class Word(MDTextField):
def __init__(self, **kwargs):
super().__init__(**kwargs)
self.input_filter = self.letters_only
def letters_only(self, substring, from_undo):
if substring.isalpha():
return substring
class TestTextFieldApp(MDApp):
def btnOnRelease(self, instance):
if (self.word.keyboard_suggestions):
self.word.keyboard_suggestions = False
self.btn.text = "Turn on keyboard suggestions"
else:
self.btn.text = "Turn off keyboard suggestions"
self.word.keyboard_suggestions = True
def build(self):
self.root = MDFloatLayout()
self.word = Word()
self.word.input_type = "text"
self.root.add_widget(self.word)
self.word.pos_hint = {"center_x": 0.5, "center_y": 0.5}
self.word.size_hint = (0.75, 0.125)
self.btn = MDFlatButton()
self.btn.text = "Turn off keyboard suggestions"
self.btn.bind(on_release=self.btnOnRelease)
self.btn.pos_hint = {"center_x": 0.5, "center_y": 0.4}
self.btn.size_hint = (0.6, 0.125)
self.root.add_widget(self.btn)
return self.root
if __name__ == '__main__':
TestTextFieldApp().run()

Robert – do you have any idea here?
I suggest removing the input filter and testing this again to make sure there is not an issue with the input filter. If the suggestion is trying to add a space, it will not be accepted by the filter.

I suggest you look back at the GitHub issue link. If the solution at the link does not work – ask there. I have not done any android programing.
