In the HelloGallery sample they state how to add the default gray border in step 5 by using an attrs.xml
file. If you don't want the border you can simple skip this step.
In the next step an ImageAdapter is created, in the constructor they apply the border to all items. If you change the constructor to the following code the border should be gone and you should only have a row of your images left:
public ImageAdapter(Context c) {
mContext = c;
TypedArray a = obtainStyledAttributes(R.styleable.HelloGallery);
a.recycle();
}
Also, in the getView
method there's a line i.setBackgroundResource(mGalleryItemBackground);
which can be removed in this case.
Hope this helps you a little bit in the right direction.
