How should be handled onFocusChange for view in compose? I meant that keyboard is not always called automatically and we need a view reference in order to present it or hide it. It there any clean way to handle from composable?

You mean this onFocusChange?

yes, but how could I expose this to activity in order to call imm.showKeyboard() blabla.. ?

and more precise how can I get an id of the view to focus on

Why do you need to do that in your activity? The TextField provides a soft keyboard controller: https://cs.android.com/androidx/platform/frameworks/support/+/androidx-master-dev:ui/ui-foundation/src/main/java/androidx/ui/foundation/TextField.kt;drc=a69d17b1108d220aab5b2e902c886d92cc9199cb;l=245

oh, nice. Did not noticed that it returns already keyboard. Thanks.

One more question… if I have a livedata with text coming from input, what is usual way to convert it into TextFieldValue?

[Zach Klippenstein (he/him) [MOD]]

(although if you're still interested, there's a focus modifier for controlling focus inside Compose - composables do not have Android IDs)

liveData.observeAsState

[aipok]

and how pass it later to TextFieldValue(stateName.value ?: “”)?
