Question

I used Horizontal scroll view in which I add ‘Child View’. But on HZ scroll view I want to arrange child some think like, whole screen will show 3.5 child at a time or 4.5 , 5.5 depends on screen size. The half of child indicate there is more child on Scroller.

For that I used different dimensions for child view depends on density. But still their is some device which show whole child at the end of screen.

So how I can mange this on scroll view. Please guide me in right direction.

end of screen.

That will not work well in a lot of devices.
Assuming that those orange child views are all of the same width(although not that important) and you want to show half of one only when the HorizontallScrollView is first laid out, you could simply post a Runnable(in the onCreate method) on a view to set their widths to a proper dimension so you make the proper appearance:

public void onCreate(Bundle saved) {
    // ... work   
    horizontalScrollView.post(new Runnable() {

            @Override
            public void run() {
                DisplayMetrics dm = getResources().getDisplayMetrics();
                int screenWidth = dm.widthPixels;
                // based on this width, the space between the children and their
                // widths calculate new widths so you get a half clipped
                // children on the right side.
            }
        });
}

But, I would avoid this and simply set a much more powerful indicator on the HorizontalScrollView(overriding its dispatchDraw method and drawing something there(maybe also hiding it a bit later with a Runnable)) if you really want to make sure that the user sees the extra content.
