Help on soft keyboard handling

[Marekeon]

Hi, im still fairly new to toga but making quick progress with my Android app. What I'm struggling with right now is the fact that when I change focus after having performed summer user input in a text fields, the keyboard remains open.

I saw that there is already an engagement"iOS App needs a "native" way to remove keyboard from view #1236" but it's already quite old and open. Maybe someone had the same issue and found a workaround?
Many thanks in advance!

The only workaround I can think of would be to invoke the native API to hide the keyboard - on a text input I believe:

my_text_input._impl.native.endEditing(True)

should work; another approach that should work on any input widget would be:

my_widget._impl.native.resignFirstResponder()

There are iOS-specific APIs though - they won't work on any other platform.

Thanks for the feedback!
That doesn't seem to work on my android setup indeed.. Is there any way to use this "_impl.native." to get access to java/kotlin and issue commands around the InputMethodManager ? or to send a command, like the sendKeys() in some other programming languages? sending the key "back" would probably do the trick as well?

The ..._impl.native part will be the same on every platform; it's what you invoke on the native object that will change.

I don't know the Android solution off the top of my head, but this SO answer has a couple of suggestions. From the look of it, they might not be methods on the native textinput widget, though, so you'll need to find a path to the native widget that has the API.

In that SO answer:

• The equivalent of view is widget._impl.native, where widget is any widget in your app.
• The equivalent of the implicit this on which getSystemService is called is app._impl.native, where app is your App object.

Thank you very much for the hints! My different attempts all miserably failed for now (a bit beyond my competence...), but as a temporary workaround, just reloading the window content worked:
self.app.main_window.content = self

I'll check later if I manage to use this _impl.native, as that really opens infinite doors :D
