how to use same array in another class

Question

In my mainactivity.java I am setting images from drawable in a array list.

Like this:

static final int[] ICONS = new int[] { R.drawable.cover_akon, R.drawable.cover_justin,
            R.drawable.cover_alright, R.drawable.cover_big_sean, R.drawable.cover_britney, R.drawable.cover_hilary,
            R.drawable.cover_mb, R.drawable.cover_akon, R.drawable.cover_justin, R.drawable.cover_alright,
            R.drawable.cover_big_sean, R.drawable.cover_britney, R.drawable.cover_hilary, R.drawable.cover_mb,
            R.drawable.cover_britney, R.drawable.cover_hilary, R.drawable.cover_mb, R.drawable.cover_akon,
            R.drawable.cover_justin, R.drawable.cover_alright, R.drawable.cover_big_sean, R.drawable.cover_britney,
            R.drawable.cover_hilary, R.drawable.cover_mb, R.drawable.cover_akon, R.drawable.cover_justin,
            R.drawable.cover_alright, R.drawable.cover_big_sean, R.drawable.cover_britney, R.drawable.cover_hilary,
            R.drawable.cover_mb, R.drawable.cover_akon, R.drawable.cover_justin, R.drawable.cover_alright,
            R.drawable.cover_big_sean, R.drawable.cover_britney, R.drawable.cover_hilary, R.drawable.cover_mb,
            R.drawable.cover_britney, R.drawable.cover_hilary, R.drawable.cover_mb, R.drawable.cover_akon,
            R.drawable.cover_justin, R.drawable.cover_alright, R.drawable.cover_big_sean, R.drawable.cover_britney,
            R.drawable.cover_hilary, R.drawable.cover_mb };

And I am also creating an image array list in another class swipeactivity.java

like this:

private int[] mImages = new int[] 
    {           
            R.drawable.cover_akon, R.drawable.cover_justin,
            R.drawable.cover_alright, R.drawable.cover_big_sean, R.drawable.cover_britney, R.drawable.cover_hilary,
            R.drawable.cover_mb, R.drawable.cover_akon, R.drawable.cover_justin, R.drawable.cover_alright,
            R.drawable.cover_big_sean, R.drawable.cover_britney, R.drawable.cover_hilary, R.drawable.cover_mb,
            R.drawable.cover_britney, R.drawable.cover_hilary, R.drawable.cover_mb, R.drawable.cover_akon,
            R.drawable.cover_justin, R.drawable.cover_alright, R.drawable.cover_big_sean, R.drawable.cover_britney,
            R.drawable.cover_hilary, R.drawable.cover_mb, R.drawable.cover_akon, R.drawable.cover_justin,
            R.drawable.cover_alright, R.drawable.cover_big_sean, R.drawable.cover_britney, R.drawable.cover_hilary,
            R.drawable.cover_mb, R.drawable.cover_akon, R.drawable.cover_justin, R.drawable.cover_alright,
            R.drawable.cover_big_sean, R.drawable.cover_britney, R.drawable.cover_hilary, R.drawable.cover_mb,
            R.drawable.cover_britney, R.drawable.cover_hilary, R.drawable.cover_mb, R.drawable.cover_akon,
            R.drawable.cover_justin, R.drawable.cover_alright, R.drawable.cover_big_sean, R.drawable.cover_britney,
            R.drawable.cover_hilary, R.drawable.cover_mb
    };

but what i want is how can i use same image array list in another class. i want to use static final int[] ICONS = new int[] (mainactivity.java) so i don't have to create new array list (don't have to create "private int[] mImages = new int[]" in swipeactivity.java)

what I want is like this example:

Main.java

static final int[] ICONS = new int[] 
{ 
R.drawable.cover_akon, R.drawable.cover_justin,
R.drawable.cover_akon, R.drawable.cover_akon,
R.drawable.cover_akon, R.drawable.cover_3,
}

Swipe.java

private int[] mImages = ICONS;

I hope you got what I mean.

I want to use a single array list in both class like above example.

Um, if it's static final, then you can just access it as int[] icons = MainActivity.ICONS; — EpicPandaForce

You can already access them since they are static.

MainActivity.ICONS will return array list.
