android java -如何在Google Maps api的折线中设置可见性false和true？

implementation 'com.google.android.gms:play-services-maps:17.0.0'

<com.google.android.gms.maps.MapView
    android:id="@+id/mapView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapView;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Polyline;
import com.google.android.gms.maps.model.PolylineOptions;

public class MainActivity extends AppCompatActivity implements OnMapReadyCallback {
    private MapView mapView;
    private GoogleMap googleMap;
    private Polyline polyline;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mapView = findViewById(R.id.mapView);
        mapView.onCreate(savedInstanceState);
        mapView.getMapAsync(this);
    }

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

        // 添加折线
        PolylineOptions polylineOptions = new PolylineOptions()
                .add(new LatLng(37.35, -122.0))
                .add(new LatLng(37.45, -122.0))
                .add(new LatLng(37.45, -122.2))
                .add(new LatLng(37.35, -122.2))
                .add(new LatLng(37.35, -122.0))
                .visible(true); // 设置折线可见性为true
        polyline = googleMap.addPolyline(polylineOptions);
    }
}

polyline.setVisible(false); // 设置折线可见性为false，隐藏折线
