Is it possible to display the small button to change the map type using Android and Maps fragment?

Question

When using Google Maps on the bottom left you have an icon to change the map type, I want to add this functionnality to my small Android application but I can't figure out how.

Here is what I have:

    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;

        getLastLocation();
        mMap.setMyLocationEnabled(true);
        mMap.getUiSettings().setMyLocationButtonEnabled(true);
        mMap.getUiSettings().setMapToolbarEnabled(true);
        mMap.getUiSettings().setCompassEnabled(true);
        mMap.getUiSettings().setZoomControlsEnabled(true);

        // different types of maps
      /*  mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
        mMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
        mMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
        mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);*/

    }  

I tried to check the getUiSettings but it seems like there isn't an option for that ? (which I find a bit strange)

It's simple :)

Use FAB in your map XML File like this:

 <com.google.android.material.floatingactionbutton.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="top|right"
    android:layout_margin="@dimen/fab_margin"
    app:backgroundTint="#0D640B"
    app:elevation="20dp"
    app:fabSize="mini"
    app:rippleColor="#0D640B"
    app:srcCompat="@android:drawable/ic_menu_map_type" />

Then add this lines in your Map Activity:

  FloatingActionButton fab = root.findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if (GoogleMap.MAP_TYPE_NORMAL == mMap.getMapType()) {
                mMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
            } else {
                mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
            }
