java - Android Spinner not responing to clicks, does not close and OnItemSelectedListener does not fire off -


i developing app in kotlin (if don't know kotlin sure can still android/java experience)

details:

i have spinner in there app.though not responding clicks once pops , shows weird views. , because of onitemselected listener never fired either.

i start method update spinner asyncrealm call.

here's code:

this whole function runs, spinner not null, after attaching listener, no longer null either (when debugging).

    private fun updatecategoryspinner(result: mutablelist<category>) {         info("updatecategoryspinner")         val arrayadapter: arrayadapter<string> = arrayadapter(ctx, r.layout.spinner_item, result.map{ it.category })         arrayadapter.setdropdownviewresource(r.layout.spinner_item)         arrayadapter.notifydatasetchanged()         categoryspinner.adapter = arrayadapter         info("updatecategoryspinner done")     }

result.map{..} creates mutablelist category names.

problem:

i have no idea why there arrows, no matter layout use (even if simple textview) there

what missing here?

disabling listener doesn't help.

attaching listener anko doesn't help.

the listener fires once when initialized, that's it.

once dropdown opens stuck.

i creating views anko.

the r.layout.spinner-item <textview>.

class addtodofragmentui:ankocomponent<viewgroup>,ankologger {     override fun createview(ui: ankocontext<viewgroup>): view {         val edittexttheme = r.style.widget_appcompat_edittext          return with(ui){             verticallayout {                 info("inverticallayout")                 verticalpadding =dip(15)                 gravity = gravity.center                 edittext(edittexttheme){                     id = r.id.txt_todo_desc                     hintresource = r.string.txt_todo_desc_hint                     width = matchparent                  }                 spinner(r.style.widget_appcompat_spinner){                     id= r.id.spinner_todo_category                     prompt = "select category"                 }                 button{                     id = r.id.btn_add_todo                     textresource = r.string.btn_add_todo                     width = matchparent                  }                 button{                     id = r.id.btn_del_todo                     textresource = r.string.btn_del_todo                     width = matchparent                     visibility = view.invisible                  }              }.applyrecursively {view -> when(view){                 edittext -> view.textsize = 20f                 button -> view.textsize = 30f             }             }         }     }

spinner dropped-down

okay, issue of non-responsiveness setting widget_app_compact spinner theme.

 spinner(r.style.widget_appcompat_spinner){                     id= r.id.spinner_todo_category                     prompt = "select category"

removing solves problem.

don't lose 2 days did on this, please :d.
