@Override
    public void onBackPressed() {
        super.onBackPressed();

        int position=100;
        position=getIntent().getExtras().getInt("position");
        NewsListAdapter newsListAdapter=new NewsListAdapter();
        Constants.sVisited=position;
        newsListAdapter.notifyDataSetChanged();

    }
