Adam Powell · Answer

it ll be kind of ugly but your entry point for what it s trying to do is here <https cs android com androidx platform frameworks support + androidx main compose ui ui src androidMain kotlin androidx compose ui platform WindowRecomposer android kt l=79 q=WindowRecomposer amp sq=|https cs android com androidx platform frameworks support + androidx main compose form WindowRecomposer android kt l=79 q=WindowRecomposer amp sq=>

Adam Powell · Answer

the composition needs a parentCompositionContext set on the view to be able to measure and AutoCompleteTextView tries to measure unattached views to determine the size of the popup window to create

Adam Powell · Answer

if a parentCompositionContext isn t present the ComposeView will search the view tree for one If it s attached to a window then a window scoped recomposer will be lazily created at that point

Adam Powell · Answer

you can install one yourself in the window where the AutoCompleteTextView is attached by doing what this internal property does <https cs android com androidx platform frameworks support + androidx main compose ui ui src androidMain kotlin androidx compose ui platform WindowRecomposer android kt l=227 q=WindowRecomposer>

I believe I understand and will give this an attempt Thank you Adam smile

Adam Powell · Answer

it should make things easier that we recently opened the create function for this as experimental so you can at least call that to create one instead of having to copy all of that slightly smiling face

Adam Powell · Answer

that might only be in the recent alphas I forget if it was experimental in 1 1 or only `internal`
