Android 如何使用动画使图像像吃角子老虎机一样滚动？

我有静态的ImageView，当我点击一个按钮时，它的内容会随机改变。 如何使图像像这样滚动：

我在以下位置使用Android Wheel： 我的适配器：

private class SlotMachineAdapter extends AbstractWheelAdapter {
    // Layout inflater
    private Context context;

    /**
     * Constructor
     */
    public SlotMachineAdapter(Context context) {
        this.context = context;
    }

    @Override
    public int getItemsCount() {
        return arrImgList.size();
    }

    // Layout params for image view
    final ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

    @Override
    public View getItem(int index, View cachedView, ViewGroup parent) {
        ImageView img;

        if (cachedView != null) {
            img = (ImageView) cachedView;
        } else {
            img = new ImageView(context);
        }

        img.setLayoutParams(params);

        Bitmap bitmap = BitmapFactory.decodeFile(arrImgList.get(index));
        Bitmap scaled = Bitmap.createScaledBitmap(bitmap, widthWheel, heightWheel, true);
        bitmap.recycle();

        img.setImageBitmap(scaled);

        return img;
    }
}

我想要这样的图像改变效果。谢谢先生。我不能使用gif，因为我的图像是由用户添加的。你试过jquery动画吗？我是初级开发人员，我不知道如何使用动画。让我搜索jqueryanimate。请做研究并在这里发布您的答案。

    Bitmap bmImg = BitmapFactory.decodeFile(arrImgList.get(pickedNumber));
    img.setImageBitmap(bmImg);

private class SlotMachineAdapter extends AbstractWheelAdapter {
    // Layout inflater
    private Context context;

    /**
     * Constructor
     */
    public SlotMachineAdapter(Context context) {
        this.context = context;
    }

    @Override
    public int getItemsCount() {
        return arrImgList.size();
    }

    // Layout params for image view
    final ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

    @Override
    public View getItem(int index, View cachedView, ViewGroup parent) {
        ImageView img;

        if (cachedView != null) {
            img = (ImageView) cachedView;
        } else {
            img = new ImageView(context);
        }

        img.setLayoutParams(params);

        Bitmap bitmap = BitmapFactory.decodeFile(arrImgList.get(index));
        Bitmap scaled = Bitmap.createScaledBitmap(bitmap, widthWheel, heightWheel, true);
        bitmap.recycle();

        img.setImageBitmap(scaled);

        return img;
    }
}
