Change border style in Gallery

I am t开发者_如何学编程aking this tutorial. As you can see on this image, the standard grey border is applied to all elements in the gallery. I would like to remove this rather ugly border, or, actually, make it a 1 px border instead (or just so the images can be distinguished from each other). I tried removing this line:

imgView.setBackgroundResource(GalItemBg);

That removes the border, but then the images overlap each other and it's still not very pretty.

So, how do I change the border? And how do I get the gallery elements to not overlap each other?

I'm sure you've already discovered an answer for this problem, but as there's none posted, here's one now!

You can place each of your imgView objects inside of a RelativeLayout with a black background and a 1 padding. Then return the RelativeLayout object containing the ImageView instead of returning the ImageView itself.

public View getView(int position, View convertView, ViewGroup parent)
{
    ImageView imgView = new ImageView(m_Context);
    // do stuff initializing your imgView as before
    RelativeLayout borderImg = new RelativeLayout(m_Context);
    borderImg.setPadding(1,1,1,1);
    borderImg.setBackgroundColor(0xff000000);
    borderImg.addView(imgView);
    return borderImg;
}

Finally, it is much easier to enforce a spacing between your Gallery images by using the Gallery method setSpacing(int pixels) to put a space between each Gallery object. You won't get the black border around them, but the Gallery background will be visible between and behind them.
