<FrameLayout
    android:id="@+id/map_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

SupportMapFragment mapFragment = SupportMapFragment.newInstance();

FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.map_container, mapFragment);
fragmentTransaction.commit();

mapFragment.getMapAsync(new OnMapReadyCallback() {
    @Override
    public void onMapReady(GoogleMap googleMap) {
        // 在地图准备就绪后的回调中进行地图相关操作
        // 可以设置地图类型、添加标记、设置缩放级别等
    }
});
