Android ViewPager padding/margin between page fragments

Question

Android Market/Google Music seem to be able to have a gap of some sort between the different fragments that are contained in the ViewPager.

Any idea how this is done? Adding margin/padding to the actual fragment view doesn't work, because the view still needs to occupy the entire width of the screen. The 'gap' is only visible when swiping the ViewPager.

In Support Package, r4 you can use these methods:

setPageMargin(int marginPixels)
setPageMarginDrawable(Drawable)
setPageMarginDrawable(int)

in ViewPager class.

I don't know why this doesn't have equivalent in XML :-(

If you need use dip unit you can use this method:

public static int convertDip2Pixels(Context context, int dip) {
    return (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dip, context.getResources().getDisplayMetrics());
}
