How to open a viewpager fragment when a recyclerview item is clicked

Question

I'm new in android. I have a navigation drawer where i used recyclerview for the item. I have three tabs representing three fragments in a viewpager. My problem is that i can not open a fragment by clicking recycler view item. And another problem is that I tried FragmentTransaction but don't know how to get the fragment id. Please help me i'm stuck on it.You can give me any tutorial link.

Here is my code...

In my recyclerview adapter i have tried:

public void onBindViewHolder(MyViewHandler holder, int position) {

    final Information current = data.get(position);
    holder.title.setText(current.title);
    holder.icon.setImageResource(current.iconId);
    holder.title.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            fragmentJump(current);
        }
    });

}
private void fragmentJump(Information mItemSelected) {
    mFragment = new FragmentIncome();
    mBundle = new Bundle();
    mBundle.putParcelable("item_selected_key", mItemSelected);// here my Information class is not parcelable how to solve it?
    mFragment.setArguments(mBundle);
    switchContent(R.id.frag1, mFragment);/// Here how to get the fragment id in R.id.frag1 of viewpager
}
public void switchContent(int id, Fragment fragment) {
    if (mContext == null)
        return;
    if (mContext instanceof MainActivity) {
        MainActivity mainActivity = (MainActivity) mContext;
        Fragment frag = fragment;
        mainActivity.switchContent(id, frag);
    }

}

And in the MainActivity i have created this method:

 public void switchContent(int id, Fragment fragment) {
    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    ft.replace(id, fragment, fragment.toString());
    ft.addToBackStack(null);
    ft.commit();
}

I have followed this link how to open a different fragment on recyclerview OnClick

You can do this by using interface callback when a recyclerview item is clicked:

You could do this:

class NavdrawerRecyclerAdapter extends RecyclerView.Adapter<> {

private OnFragmentInteractionListener mListener;

public NavdrawerRecyclerAdapter(OnFragmentInteractionListener listener){
mListner = listner;
}

//call and pass position inside onClick
public void onRecyclerItemClicked(int pos){
mListener.openFragment(pos);
}


public interface OnFragmentInteractionListener{
public void openFragment(int pos);
}}

Now your mainactivity which has tablayouts implement this interface.

public class MainActivity extends AppCompatActivity implements NavdrawerRecyclerAdapter.OnFragmentInteractionListener{

NavdrawerRecyclerAdapter adapter = new NavdrawerRecyclerAdapter(this);

@override
openFragment(int position){
TabLayout.Tab tab = tabLayout.getTabAt(position);
tab.select();
}
}

Try it and tell me if this works.

It doesn't work. It don't make any change in the app. On click is not working – Fatema Dec 01 '16 at 06:36
which onClick is not working the recyclerview's onClick – pawar Dec 01 '16 at 06:41
it's onRecyclerItemClicked – Fatema Dec 01 '16 at 06:44
I meant that item can not be clicked. – Fatema Dec 01 '16 at 07:05
ok so do one thing you can add onclick listener inside recycler view's adapter (i.e. on textviews or whatever item you are clicking). Recycler view has on Item Touch Listener you can either use that. Tell me if this helps. – pawar Dec 01 '16 at 09:26
What should i do in onClick method? – Fatema Dec 01 '16 at 09:43
I have edited the answer for you. After onclick please write the above code. Tell me if it works. – pawar Dec 01 '16 at 10:18
