Managed to make it work, now the content width is set to wrap_content and you can give gravity to your parent layout.

Add this function to the component class file.
public void resetPosition() {

if (mContext != null && mAdapter != null) {

    DisplayMetrics metrics = mContext.getResources()
            .getDisplayMetrics();
    int width = metrics.widthPixels;

    if (mAdapter.getCount() * mChildWidth > 0
            && mAdapter.getCount() * mChildWidth < width) {

        Log.e("child width", "child: " + mAdapter.getCount()
                + ": width:" + mChildWidth + "");

        setLayoutParams(new LinearLayout.LayoutParams(
                mAdapter.getCount() * mChildWidth, 300));
    }
}

}
After you set the adapter/notifydatasetchanged

call the function like

yourHorizontalListView.post(new Runnable() {

        @Override
        public void run() {
            // TODO Auto-generated method stub
            yourHorizontalListView.resetPosition();

        }
    }); 

Worked in my case.
