android gallery image position problem

I'm using Gallery view within my app. Now when I run the code. Gallery has default selected item is no 1 which is in center and left side is blank. Instead I want no 1 item should be at left and selected. Also clicking on the any gallery item should not bring that item in the center.

I tired hunting it lot on the groups but not found any solution. Is this possible or not ? If yes then how come?

hey, I kinda got around the very same issue with adjusting the left margin like so:

DisplayMetrics metrics = new DisplayMetrics();
ctx.getWindowManager().getDefaultDisplay().getMetrics(metrics);

Gallery gallery = (Gallery) ctx.findViewById(R.id.gallery);

MarginLayoutParams mlp = (MarginLayoutParams) gallery.getLayoutParams();
mlp.setMargins(-(metrics.widthPixels/2), 
               mlp.topMargin, 
               mlp.rightMargin, 
               mlp.bottomMargin
);

which goes almost to the left edge, but there is a bit of slack (half image width?), which I actually liked;

if you replace

-(metrics.widthPixels/2)

with

-(metrics.widthPixels/2 + YOUR_IMAGE_WIDTH)

it goes all the way to left edge of the screen (provided this gallery is displaying images of same size, which was my case)
