我已经为这样的arraylist增加了一些价值:

    private List<InfoProduct> product;

    product = new ArrayList<>();
    product.add(new InfoProduct(R.drawable.cloth, Product_title, "0", Product_data2, lunch,R.drawable.cardview_circle_corner));
    product.add(new InfoProduct(R.drawable.guitar, Product_title, "1", Product_data2, lunch,R.drawable.cardview_circle_corner));
    product.add(new InfoProduct(R.drawable.cloth, Product_title, "2", Product_data2, lunch,R.drawable.cardview_circle_corner));
    product.add(new InfoProduct(R.drawable.guitar, Product_title, "3", Product_data2, lunch,R.drawable.cardview_circle_corner));
    product.add(new InfoProduct(R.drawable.cloth, Product_title, "4", Product_data2, lunch,R.drawable.cardview_circle_corner));
    product.add(new InfoProduct(R.drawable.guitar, Product_title, "5", Product_data2, lunch,R.drawable.cardview_circle_corner));
    product.add(new InfoProduct(R.drawable.cloth, Product_title, "6", Product_data2, lunch,R.drawable.cardview_circle_corner));
    product.add(new InfoProduct(R.drawable.guitar, Product_title, "7", Product_data2, lunch,R.drawable.cardview_circle_corner));
    product.add(new InfoProduct(R.drawable.cloth, Product_title, "8", Product_data2, lunch,R.drawable.cardview_circle_corner));
    product.add(new InfoProduct(R.drawable.guitar, Product_title, "9", Product_data2, lunch,R.drawable.cardview_circle_corner));

当我需要去其他Fragment时,我想使用Bundle来传输我的ArrayList,所以我写了一些代码来遵守这个

    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    ft.replace(R.id.fragment_youtube, new FragmentYoutubeProduct(), "youtube");
    ft.addToBackStack("youtube");
    Bundle bundle …
