Put all drawable folder images directly in arraylist

Issue

I am developing an android game app and I have more then 150 images inside my app! I want to put all images which exist in drawable package in a ArrayList. I have this code

InputStream ips = getAssets().open("Arrow001.jpg");
        Drawable d = Drawable.createFromStream(ips, null);
        questionImageView.setImageDrawable(d);

but i don't want to add them one by one in myArray and i want to use a loop for generate images in arrayList when i run my app!

Thanks for your help

Solution

You can get array of all assets files on root assets folder by calling

String[] list = getAssets().list("")

In our case you can write code like below.

for (String assetPath : getAssets().list("")) {
    InputStream ips = getAssets().open(assetPath);
    //yours code
}
