Question

I have a bitmap of 9X11 pixels representing a maze with the path in green, walls in black, start in orange and blue end.

it matrix is:

int[][] map = new int[][] { 
            { 1, 1, 1, 1, 1, 1, 1, 1, 1 }, 
            { 0, 0, 1, 0, 0, 0, 0, 0, 1 },
            { 1, 1, 1, 1, 0, 1, 1, 0, 1 }, 
            { 1, 1, 1, 1, 1, 1, 1, 0, 0 },
            { 1, 0, 0, 0, 0, 1, 0, 0, 0 }, 
            { 1, 1, 1, 1, 0, 1, 1, 1, 1 },
            { 1, 1, 1, 1, 0, 1, 0, 0, 1 }, 
            { 1, 1, 1, 1, 0, 1, 0, 0, 1 },
            { 1, 1, 1, 1, 0, 1, 0, 0, 1 }, 
            { 1, 1, 1, 1, 0, 1, 0, 0, 0 },
            { 1, 1, 1, 1, 0, 1, 1, 1, 1 }, };

The problem is that when I draw the bitmap in a ImageView (fill_parent,fill_parent) the result is:

How can I keep the pixels squared?

Note: I create the Bitmap with

 Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);

and set the pixels with the method

 bitmap.setPixel(x,y,Color.XXX);

If you want an image view to scale without antialiasing, what you really need to do is get a BitmapDrawable. Example:

BitmapDrawable bd = new BitmapDrawable(activity.getResources(), bitmap);
bd.setAntiAlias(false);
