Question

我有一个AnimatedSprite元素，我想对它应用一些修饰符（AlphaModifier，ScaleModifier，...）

修改器完成后，应删除AnimatedSprite元素。正常调用时removeFace（）方法正常工作。但是我在onModifierFinished（）方法中调用它，然后我收到错误。我是这样实现的。

void removeBallWithModifier(final AnimatedSprite ball) {

    final LoopEntityModifier em = new LoopEntityModifier(
            new SequenceEntityModifier(new ParallelEntityModifier(
                    new AlphaModifier(1, 1, 0.4f), new ScaleModifier(1, 1,
                            0.4f), new RotationByModifier(1, 270))), 1,
            new IEntityModifierListener() {
                @Override
                public void onModifierStarted(IModifier<IEntity> pModifier,
                        IEntity pItem) {
                }

                @Override
                public void onModifierFinished(
                        IModifier<IEntity> pModifier, IEntity pItem) {
                    ball.setVisible(false);
                    removeFace(ball);
                }
            });
    ball.registerEntityModifier(em);
}

void removeFace(final AnimatedSprite face) {
    final PhysicsConnector facePhysicsConnector = this.mPhysicsWorld.getPhysicsConnectorManager().findPhysicsConnectorByShape(face);

    this.mPhysicsWorld.unregisterPhysicsConnector(facePhysicsConnector);
    this.mPhysicsWorld.destroyBody(facePhysicsConnector.getBody());

    this.mScene.unregisterTouchArea(face);
    this.mScene.detachChild(face);

    System.gc();
}

也许你应该尝试这样的事情

  YourClassName.this.runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                      ball.setVisible(false);
                       removeFace(ball);
                            }
                         });
