04/15/2020, 7:53 PManyone who would know, why following code fails because of type inference ?
Jiri Bruchanov
04/15/2020, 7:54 PM Copy code
private val working = listOf<Pair<String, (View) -> Unit>>(
"FOCUS_DOWN" to { it -> it.requestFocus(View.FOCUS_DOWN) }
)
Type inference failed. Expected type mismatch: inferred type is Pair<String, () -> [ERROR : <ERROR FUNCTION RETURN TYPE>]> but Pair<String, (View) -> Unit> was expected
private val failing = listOf<Pair<String, (View) -> Unit>>(
"FOCUS_DOWN" to { it.requestFocus(View.FOCUS_DOWN) }
)Jiri Bruchanov

//following is fine
"FOCUS_DOWN" to { it -> it.requestFocus(View.FOCUS_DOWN)
//this one fails
"FOCUS_DOWN" to { it.requestFocus(View.FOCUS_DOWN) }s

04/15/2020, 8:48 PM@Zach Klippenstein (he/him) [MOD] don't think so, how can I confirm that ?
Jiri Bruchanov
04/15/2020, 8:49 PMdoesn't seem to be related to IDE...
just compiling it via gradle fails with same error

04/15/2020, 8:58 PMOpen settings, search for Kotlin Compiler settings, there should be a checkbox to enable new type inference. But yea sounds like that's irrelevant, nvm.
