Describe the bug Keyboard suggestions for TextInput do not work correctly on android. Words are inputted twice when you use a suggestion or swipe as you can notice when you delete the words or press enter. Setting keyboard_suggestions to false does not deactivate suggestions.

Expected behavior Keyboard suggestions or swiping should input words correctly and it should be possible to deactivate the suggestions feature with keyboard_suggestions set to false.

To Reproduce

from kivy.app import App
from kivy.lang import Builder


kv = """
Screen:
    TextInput:
        size_hint_y: None
        height: dp(45)
        hint_text: "keyboard_suggestions: False"
        write_tab: False
        keyboard_suggestions: False
        pos_hint: {"top": 0.9}
    TextInput:
        size_hint_y: None
        height: dp(45)
        hint_text: "keyboard_suggestions: True"
        write_tab: False
        keyboard_suggestions: True
        pos_hint: {"top": 0.7}
"""


class Test(App):
    def build(self):
        return Builder.load_string(kv)


Test().run()

I'm wondering if it's due to https://github.com/kivy/kivy/pull/7231. Can you try a commit before that? Or maybe 2.0.0?

@dwmoffatt could you take a look?

[dwmoffatt]

I'll take a look

GBoard:

• Issue confirmed when using swipe or suggestions.

Samsung Keyboard:

• The first inputted character, keeps into TextInput.

Reverting #7231 fixed the issue.

It could potentially disrupt the UX for multiple users. @dwmoffatt any news?

I think I know what the problem is. There are some other variations/flags that need to get set for some of the autocomplete and suggestions to work properly based on how you are entering the data.

https://developer.android.com/reference/android/text/InputType

I haven't had a chance to try anything out yet. Hopefully next week I will have some time.

Update: Looks like some device vendors and keyboards are de-facto ignoring the InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS flag, so we can't really rely on this one to disable suggestions.

I'd also add that for Gboard and other keyboards its built-in "Copy" and "Paste" buttons don't work: "Copy" is disabled even if text is selected, "Paste" just does nothing. Probably "Copy" just can't detect that something is selected, but seems that "Paste" should work fine.

Hi, I would like to help you in solving the poblem, since I need it to find a solution quickly. May you tell me which files (and/or part of codes) I have to check and modify (including the event on keyboard) to try to find a solution?

Thank you

Indeed should be (input_type:"text" added) :

from kivy.app import App
from kivy.lang import Builder


kv = """
Screen:
    TextInput:
        size_hint_y: None
        height: dp(45)
        hint_text: "keyboard_suggestions: False"
        write_tab: False
        keyboard_suggestions: False
        pos_hint: {"top": 0.9}
    TextInput:
        size_hint_y: None
        height: dp(45)
        hint_text: "keyboard_suggestions: True"
        input_type: "text"
        write_tab: False
        keyboard_suggestions: True
        pos_hint: {"top": 0.7}
"""


class Test(App):
    def build(self):
        return Builder.load_string(kv)


Test().run()
