Button onclicklistener not fired in Fragment - android-fragments

Question

I'm using Kotlin 1.3.61, kotlin extensions, androidx.appcompat:appcompat:1.1.0, androidx.constraintlayout:constraintlayout:1.1.3, androidx.core:core-ktx:1.1.0, org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.61
and access a button defined in my xml in the fragment, like so:
class MyFragment : Fragment(), OnMapReadyCallback {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
Log.i(TAG, "In onCreate()")
}
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
Log.i(TAG, "In onCreateView()")
return inflater.inflate(R.layout.fragment_map_bottom_view, container, false)
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
...
whereBtn.setOnClickListener {
Log.i(TAG, "where clicked but first click doesn't register")
}
but the first click of the button is never fired but the second and subsequent clicks do fire.
I tried #ContainerOptions(CacheImplementation.SPARSE_ARRAY) for the fragment but no luck.
Here is the fragment layout file:
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

Answer 1

it seems that whereBtn is focusable.
There is no event to perform click at first time because focus change already has consumed the event.
