Pass an array from an Activity to a View Android

I'm coding an app for android. How can I pass an int array from my activity to my view class? I've searched but not found anything that seems to answer my question. I have this class:

public class ConvertToGrid extends Activity{...}

which takes the user's input from the Main activity's layout (using an intent) and converts it into an int array: int[] binary = {...} which has 64 values. How do I get it into this:

public class DrawGrid extends View{...}

I naively tried an intent but unless I was doing it wrong, it seemed like the wrong thing to do for a view! Also, as an aside I assume I don't need to declare my View in the Manifest like I do my activities?

Create a constructor that it has usual parameters plus int array,for example:

public class DrawGrid extends View {

    private int[] intArray;

    public DrawGrid(Context context,int[] intArray) {
        super(context);
        // TODO Auto-generated constructor stub
            this.intArray = intArray;
    }

    public DrawGrid(Context context, AttributeSet attrs, int defStyle,int[] intArray) {
        super(context, attrs, defStyle);
        // TODO Auto-generated constructor stub
            this.intArray = intArray;
    }

    public DrawGrid(Context context, AttributeSet attrs,int[] intArray) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
            this.intArray = intArray;
    }

public class DrawGrid extends View{
int[] binary;

public void setBinaryData(int[] binary)
{
  this.binary = binary
}
