示例代码




// 主活动代码示例


public class MainActivity extends AppCompatActivity {


    private ArFragment arFragment;


 


    @Override


    protected void onCreate(Bundle savedInstanceState) {


        super.onCreate(savedInstanceState);


        setContentView(R.layout.activity_main);


 


        arFragment = (ArFragment) getSupportFragmentManager().findFragmentById(R.id.ar_fragment);


        arFragment.setOnTapArPlaneListener(


            (HitResult hitResult, Plane plane, MotionEvent motionEvent) -> {


                Anchor anchor = hitResult.createAnchor();


                placeObject(arFragment, anchor, R.raw.andy);


            }


        );


    }


 


    private void placeObject(ArFragment arFragment, Anchor anchor, int resourceId) {


        ModelRenderable.builder()


            .setSource(this, resourceId)


            .build()


            .thenAccept(modelRenderable -> addNodeToScene(arFragment, anchor, modelRenderable))


            .exceptionally(throwable -> {


                Toast.makeText(this, "Unable to load model", Toast.LENGTH_SHORT).show();


                return null;


            });


    }


 


    private void addNodeToScene(ArFragment arFragment, Anchor anchor, Renderable renderable) {


        AnchorNode anchorNode = new AnchorNode(anchor);


        TransformableNode node = new TransformableNode(arFragment.getTransformationSystem());


        node.setRenderable(renderable);


        node.setParent(anchorNode);


        arFragment.getArSceneView().getScene().addChild(anchorNode);


        node.select();


    }
