Androidstudio - Swap url for image in local project path

Question

Good afternoon, everyone,

I have a string that I use to set the image of some buttons:

 String imagem[] = {"https://cdn.pixabay.com/photo/2015/12121.jpg",
            "https://cdn.pixabay.com/photo/2016/0555555.jpg"};

I downloaded the images and saved in the src main images directory inside the project.

How can I replace the url in the string above with the local path?

Follow the detailed code:

In my onCreateView:

mAdapter = new ModuloAdapter(lista(), getActivity());

private List<ItemModulo> lista() {

    String titulo[] = {"A", "B", "C", "D"};

    String imagem[] = {"https://cdn.pixabay.com/photo/2015/10/19/20/01/5555.jpg",
              "https://cdn.pixabay.com/photo/2016/02/11/23/24/5554.jpg",
              "https://cdn.pixabay.com/photo/2016/11/08/05/29/44141.jpg",
              "https://cdn.pixabay.com/photo/2016/11/08/05/29/4412241.jpg"};

    for (int i = 0; i < titulo.length; i++){
            ItemModulo item = new ItemModulo();
            item.setLista(lista[i]);
            item.setImagem(imagem[i]);
            itemList.add(item);
    }

    return itemList;
}

Hello, the right is to leave project images in the drawable folder and change its nomenclature not to start with number:

src/main/res/drawable

You can call the images as follows:

        //adiciona suas imagens em um array de inteiros ao invés de String
        int[] imagem = new int[]{R.drawable.imagem1, R.drawable.imagem2, R.drawable.imagem3};

Soon, in your getters and setters changes the image and getImage to int

in his for to send the list keeps the same

Now here’s the trick, when it comes to retrieving that entire image do the following:

Drawable drawable = getResources().getDrawable(item.getImagens());

Use this drawable to set the image on the button.

The R class is responsible for communication between xml and java, and the drawable directory where the project images are stored.
