Question

所以我有一个问题......我想在我的GoogleMaps FragmentActivity中添加一个SpriteLayer，用于绘制和显示Menus，Enemys等类似内容。

首先，我创建我的GoogleMaps FragmentActivity：

public class GoogleMaps extends FragmentActivity implements OnMapReadyCallback,AndroidFragmentApplication.Callbacks,GoogleMap.OnMapLoadedCallback {

private GoogleMap mMap;

View mapView;

SupportMapFragment mapFragment;

FutureTask<PlayFabErrors.PlayFabResult<PlayFabClientModels.LoginResult>> loginTask = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    setContentView(R.layout.activity_google_maps);


    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

    mapFragment.getMapAsync(this);


    GameFragment fragment = new GameFragment();

    FragmentTransaction trans = getSupportFragmentManager().beginTransaction();

    trans.add(R.id.map,fragment);

    trans.commit();

}

@Override
public void onMapReady(GoogleMap googleMap) {

    mMap = googleMap;

    mMap.getUiSettings().setMapToolbarEnabled(false);

    mMap.getUiSettings().setZoomGesturesEnabled(false);


    // Add a marker in Sydney and move the camera
    LatLng sydney = new LatLng(-34, 151);

    mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));


    // Move the camera instantly to location with a zoom of 15.
    mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(sydney, 20));

    // Zoom in, animating the camera.
    mMap.animateCamera(CameraUpdateFactory.zoomTo(17.5f), 2000, null);



    mapView = mapFragment.getView();

    mapView.post(new Runnable() {
        @Override
        public void run() {

            int width = mapView.getMeasuredWidth();

            int height = mapView.getMeasuredHeight();

            String widthAndHeight = width + " " + height;

            Log.println(Log.ERROR,"Width and height :",widthAndHeight);
        }
    });

}

@Override
public void onMapLoaded() {


}

public static class GameFragment extends AndroidFragmentApplication
{
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
        return initializeForView(new Main());
    }

}

@Override
public void exit() {


}
}

正如你所看到的，我称之为在onCreate方法中添加片段：

GameFragment fragment = new GameFragment();

FragmentTransaction trans = getSupportFragmentManager().beginTransaction();

trans.add(R.id.map,fragment);

trans.commit();

这应创建一个新的静态GameFragment，它在GoogleMaps FragmentActivity中定义：

 public static class GameFragment extends AndroidFragmentApplication
{
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
        return initializeForView(new Main());
    }

}

此时它将从Libgdx返回Main ApplicationAdapter类作为片段。哪个已添加到R.id.map，GoogleMaps的地图布局。

以下是Main类的内容：

public class Main extends ApplicationAdapter {

SpriteBatch batch;

Texture img;

@Override
public void create () {
    batch = new SpriteBatch();
    img = new Texture("badlogic.jpg");
}

@Override
public void render () {

    Gdx.gl.glClearColor( 0, 0, 0, 1 );
    Gdx.gl.glClear( GL20.GL_COLOR_BUFFER_BIT | GL20.GL_DEPTH_BUFFER_BIT );

    batch.begin();
    batch.draw(img, 0, 0);
    batch.end();

}

@Override
public void dispose () {
    batch.dispose();
    img.dispose();
}

}

它只是画一幅画。

当我现在启动应用程序时，行为非常奇怪。首先，Libgdx碎片弹出1秒钟。在那之后它就“消失了”。然后谷歌地图被加载，但触摸事件似乎被打破，因为我不能再缩放/移动地图。

那我做错了什么？

感谢您的帮助！我很高兴能得到的一切帮助：D！
