如何使用rajawali切换对象的位图纹理？

import org.rajawali3d.materials.Material;
import org.rajawali3d.materials.textures.ATexture;

import org.rajawali3d.materials.textures.TextureManager;
import org.rajawali3d.primitives.Cube;
import org.rajawali3d.renderer.RajawaliRenderer;

public class MyRenderer extends RajawaliRenderer {
    private Cube object;
    private Texture texture1;
    private Texture texture2;

    public MyRenderer(Context context) {
        super(context);
    }

    protected void initScene() {
        object = new Cube(1);
        getCurrentScene().addChild(object);

        // 加载第一个纹理
        texture1 = new Texture("texture1", R.drawable.texture1);
        try {
            TextureManager.getInstance().addTexture(texture1);
        } catch (ATexture.TextureException e) {
            e.printStackTrace();
        }

        // 加载第二个纹理
        texture2 = new Texture("texture2", R.drawable.texture2);
        try {
            TextureManager.getInstance().addTexture(texture2);
        } catch (ATexture.TextureException e) {
            e.printStackTrace();
        }

        // 应用第一个纹理到对象的材质上
        Material material = new Material();
        material.addTexture(texture1);
        object.setMaterial(material);
    }

    public void switchTexture() {
        // 切换纹理
        if (object.getMaterial().getTextureList().get(0).getTexture() == texture1) {
            object.getMaterial().getTextureList().get(0).setTexture(texture2);
        } else {
            object.getMaterial().getTextureList().get(0).setTexture(texture1);
        }
    }
}
