在 Android 中设置谷歌地图我的位置按钮

Question

So I am trying to use a floating action button instead of the default google map's my location button. Any ideas of how can I do that? I've tried many ways, I tried to call the MyLocationButtonClick() event inside my FloatingActionButton with either the map?.uiSettings?.isMyLocationButtonEnabled true or false but it did not zoom the user position. Any help is welcome! Thanks for your time!

This is my xml with the map and the button I want to replace for the google maps my location button.

<LinearLayout android:layout_height="match_parent"
    android:layout_width="match_parent"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <com.google.android.material.floatingactionbutton.FloatingActionButton
            android:id="@+id/btn_myLocation"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:elevation="8dp"
            android:backgroundTint="#fff"
            app:borderWidth="0dp"
            android:src="@drawable/ic_round_my_location_24"
            android:layout_margin="10dp"
            android:layout_alignParentEnd="true"
            android:layout_alignParentTop="true"/>

        <fragment
            android:id="@+id/map"
            class="com.google.android.gms.maps.SupportMapFragment"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>
    </RelativeLayout>

</LinearLayout>

And here is my kotlin onCreate() with my floating button click listener

val view : View = inflater.inflate(R.layout.fragment_courier_map, container, false)

// starts google places client
Places.initialize(this.requireContext(), getString(R.string.google_maps_key))
placesClient = Places.createClient(requireContext())

// starts fused location
fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(requireContext())

view.btn_myLocation.setOnClickListener {
    map!!.setOnMyLocationButtonClickListener  {
         false
    }
}

val mapFragment = childFragmentManager.findFragmentById(R.id.map) as SupportMapFragment?
mapFragment?.getMapAsync(this)
return view

You need to modify the map's camera as follows,

map.moveCamera(
   CameraUpdateFactory.newLatLngZoom(location, DEFAULT_ZOOM.toFloat()))

to zoom into user position. Read this for more details
