Android : Imageview is not filling to the full width of the screen

I am having a strange behaviour with the layout for the nexus 5 device only.The problem is after flipping, the image is not setting to the screen size. Here is my code

img.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {


            flipCard();

        }
    });



 private void flipCard() {
    if (mShowingBack) {
        getFragmentManager().popBackStack();
        return;
    }

    // Flip to the back.

    mShowingBack = true;

    // Create and commit a new fragment transaction that adds the fragment
    // for the back of
    // the card, uses custom animations, and is part of the fragment
    // manager's back stack.

    getFragmentManager().beginTransaction()

    // Replace the default fragment animations with animator resources
    // representing
    // rotations when switching to the back of the card, as well as animator
    // resources representing rotations when flipping back to the front
    // (e.g. when
    // the system Back button is pressed).
            .setCustomAnimations(R.animator.card_flip_right_in,
                    R.animator.card_flip_right_out,
                    R.animator.card_flip_left_in,
                    R.animator.card_flip_left_out)

            // Replace any fragments currently in the container view with a
            // fragment
            // representing the next page (indicated by the just-incremented
            // currentPage
            // variable).
            .replace(R.id.container, new CardBackFragment())

            // Add this transaction to the back stack, allowing users to
            // press Back
            // to get to the front of the card.
            .addToBackStack(null)

            // Commit the transaction.
            .commit();

    // Defer an invalidation of the options menu (on modern devices, the
    // action bar). This
    // can't be done immediately because the transaction may not yet be
    // committed. Commits
    // are asynchronous in that they are posted to the main thread's message
    // loop.
    mHandler.post(new Runnable() {
        @Override
        public void run() {
            invalidateOptionsMenu();
        }
    });
}

@Override
public void onBackStackChanged() {
    mShowingBack = (getFragmentManager().getBackStackEntryCount() > 0);

    // When the back stack changes, invalidate the options menu (action
    // bar).
    invalidateOptionsMenu();
}

/**

 */
public static class CardFrontFragment extends Fragment {
    public CardFrontFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        return inflater.inflate(R.layout.singlecard, container, false);
    }
