如何在没有操作栏的应用程序中使用Mapbox PlacePicker activity？

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import androidx.appcompat.app.AppCompatActivity;
import com.mapbox.mapboxsdk.Mapbox;
import com.mapbox.mapboxsdk.maps.MapView;
import com.mapbox.mapboxsdk.maps.MapboxMap;
import com.mapbox.mapboxsdk.maps.OnMapReadyCallback;
import com.mapbox.mapboxsdk.plugins.places.picker.PlacePicker;
import com.mapbox.mapboxsdk.plugins.places.picker.model.PlacePickerOptions;

public class MainActivity extends AppCompatActivity implements OnMapReadyCallback {

    private MapView mapView;
    private MapboxMap mapboxMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Mapbox.getInstance(this, "YOUR_MAPBOX_ACCESS_TOKEN");
        setContentView(R.layout.activity_main);

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

        findViewById(R.id.btnOpenPlacePicker).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
                Intent intent;
                try {
                    intent = builder.build(MainActivity.this);
                    startActivityForResult(intent, PlacePicker.PLACE_PICKER_REQUEST);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }

    @Override
    public void onMapReady(MapboxMap mapboxMap) {
        this.mapboxMap = mapboxMap;
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == PlacePicker.PLACE_PICKER_REQUEST && resultCode == RESULT_OK) {
            com.mapbox.mapboxsdk.plugins.places.picker.model.Place place = PlacePicker.getPlace(data);
            // 处理用户选择的地点
        }
    }

    @Override
    public void onStart() {
        super.onStart();
        mapView.onStart();
    }

    @Override
    public void onResume() {
        super.onResume();
        mapView.onResume();
    }

    @Override
    public void onPause() {
        super.onPause();
        mapView.onPause();
    }

    @Override
    public void onStop() {
        super.onStop();
        mapView.onStop();
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        mapView.onSaveInstanceState(outState);
    }

    @Override
    public void onLowMemory() {
        super.onLowMemory();
        mapView.onLowMemory();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        mapView.onDestroy();
    }
}
