How to put the ArrayList into bundle

I have put some value into arraylist like this : 

    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));

when I need to go other Fragment , I want to use Bundle to transfer my ArrayList , so I write some code to comply this 

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

I got error on bundle.putStringArrayList("Product",product); , how can I do to resolve this question ?

First, make InfoProduct Parcelable Check this Link

Then use

bundle.putParcelableArrayList(product)

You can get ArrayList by

getParcelableArrayList(...)

Your code of

bundle.putStringArrayList("Product",product);

Is trying to place an array list of strings into the bundle. However, you don't have an array list of strings. You have an array list of InfoProduct

Therefore you need to put your array list of into the bundle. For this you need to use the method putParcelableArrayList

bundle.putParcelableArrayList("Product", product);

In order to do this you also need to ensure that your object InfoProduct in parcelable, which is serializable by Android. So you need to have it implement the Parcelable interface

This post might also help you with that.

You can pass the arraylist of your custom define object either by implementing serializable or parcelable.

You need to use bundle.putParcelableArrayList() and instantiate your list as private ArrayList<InfoProduct> product;.Also make sure that InfoProduct is Parcelable.
