Android 在ARCore场景窗体中添加旋转和缩放按钮？

我正在尝试在我的android应用程序中添加一个3D模型，这个应用程序运行良好（在屏幕上点击一个3D模型，用手指手势旋转它，用捏法缩放它）。我正在尝试用按钮进行手指缩放和旋转

你可以通过获得模特的位置来实现这一点。下面的方法可用于您的按钮点击。希望这对你有帮助

private void modleMovement(TransformableNode node, String moveMent) {
    Vector3 currentPosition = new Vector3();
    Vector3 move = new Vector3();

    try {
        currentPosition = Objects.requireNonNull(node.getLocalPosition());

        if (moveMent.equals("down")) {
            move.set(currentPosition.x, (float) (currentPosition.y - 0.1), currentPosition.z);
            localPosition = move;
        }

        if (moveMent.equals("up")) {

            move.set(currentPosition.x, (float) (currentPosition.y + 0.1), currentPosition.z);
            localPosition = move;
        }

        if (moveMent.equals("right_move")) {

            move.set((float) (currentPosition.x + 0.1), currentPosition.y, currentPosition.z);
            localPosition = move;
        }

        if (moveMent.equals("left_move")) {

            move.set((float) (currentPosition.x - 0.1), currentPosition.y, currentPosition.z);
            localPosition = move;
        }
         if (moveMent.equals("rotate_left")) {
            localPosition = currentPosition;
            rotateLeft(node, objAxis, currentPosition);
        }

        if (moveMent.equals("rotate_right")) {
            localPosition = currentPosition;
            rotateRight(node, objAxis, currentPosition);
        }

        if (moveMent.equals("zoom_in")) {
            move.set(currentPosition.x, currentPosition.y, (float) (currentPosition.z + 0.1));
            localPosition = move;
        }

        if (moveMent.equals("zoom_out")) {
            move.set(currentPosition.x, currentPosition.y, (float) (currentPosition.z - 0.1));
            localPosition = move;
        }


        node.setLocalPosition(move);
    } catch (Exception e) {
        e.printStackTrace();
    }
}
