如何在谷歌地图Android上找到MyLocationButton？

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;

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

    @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;
        // 在这里可以对地图进行操作，例如添加标记、设置地图类型等
    }
}

@Override
public void onMapReady(GoogleMap map) {
    googleMap = map;
    UiSettings uiSettings = googleMap.getUiSettings();
    boolean isMyLocationButtonEnabled = uiSettings.isMyLocationButtonEnabled();
    // 判断MyLocationButton是否可见
    if (isMyLocationButtonEnabled) {
        // MyLocationButton可见，可以进行相应的操作
    } else {
        // MyLocationButton不可见，可以进行相应的操作
    }
}

@Override
public void onMapReady(GoogleMap map) {
    googleMap = map;
    UiSettings uiSettings = googleMap.getUiSettings();
    uiSettings.setMyLocationButtonEnabled(true);
}
