/*----i have tried this but this is showing error....R.id.content_classroom is not a vlaid argument
            QuestionFragment qf=new QuestionFragment();
            FragmentManager fm = ((Home)context).getSupportFragmentManager();

public void setupViewPager(ViewPager viewPager) {
    MyPagerAdapter adapter = new MyPagerAdapter(getSupportFragmentManager());
    adapter.addFragment(new QuestionFragment(), FRAGMENT_NAME[0]);
    adapter.addFragment(new ArticleFragment(), FRAGMENT_NAME[1]);
    adapter.addFragment(new VideoFragment(), FRAGMENT_NAME[2]);
    //Set adapter to ViewPager
    viewPager.setAdapter(adapter);
}

create method in your fragment

public void selectTab(int position) {
    mViewPager.setCurrentItem(position);
}

Call this method to select tab.
For question - position 0,article - position 1 and video - position 2

---- Way to call method from recyclerView----
 Make your adapter class abstract

public abstract class CartAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    // constructor ..
    // Other recyclerView methods

    // You ViewHolder class
    public class CartHolder extends RecyclerView.ViewHolder {

        Button mButton;

        CartHolder(View itemView) {
            super(itemView);
            mButton = (Button) itemView.findViewById(R.id.referece_of_view);
            mButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    OnButtonClicked();
                }
            });
        }
    }

    protected abstract void OnButtonClicked();
}

While initializing your adapter,

mAdapter = new CartAdapter(context, mDataSet) {
            @Override
            protected void OnButtonClicked() {
                // Call method selectTab()
            }
};
