How open fragment from RecyclerView.Adapter<CardAdapter.ViewHolder>

Question

1.TabLayout

- tab1 (Fragment1) - tab2 (Fragment2) - tab3 (Fragment3)      * RecyclerView + CardView (OnClick) 

On CardView ClickListner open another fragment in tab3. So how to open fragment in tab3.

Error is in getFragmentManager():

FragmentTransaction transaction = getFragmentManager().beginTransaction(); 

Instead of this, I tried:

FragmentTransaction transaction = activity.getFragmentManager().beginTransaction(); FragmentTransaction transaction = itemview.getContext().getFragmentManager().beginTransaction(); 

But error is not resolve.

Here is my code:

 public class CardAdapter extends RecyclerView.Adapter<CardAdapter.ViewHolder> {      List<NatureItem> mItems;     private int lastPosition = -1;     Context context;     TaskFragment main;     public CardAdapter(Context context,TaskFragment ma)     {          this.context=context;         main=ma;     }       public CardAdapter() {         super();         mItems = new ArrayList<NatureItem>();         NatureItem nature = new NatureItem();         nature.setName("The Paris Attack 2015");         nature.setDes("Lorem ipsum dolor sit amet.");         nature.setThumbnail(R.drawable.news1);         mItems.add(nature);             }        @Override     public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int position) {         View v = LayoutInflater.from(viewGroup.getContext())                 .inflate(R.layout.custom_list, viewGroup, false);         ViewHolder viewHolder = new ViewHolder(v);       return viewHolder;     }        @Override     public void onBindViewHolder(ViewHolder viewHolder, int i) {         NatureItem nature = mItems.get(i);         viewHolder.tvNature.setText(nature.getName());         viewHolder.tvDesNature.setText(nature.getDes());         viewHolder.imgThumbnail.setImageResource(nature.getThumbnail());       //  setAnimation(viewHolder.card,i);     }       @Override     public int getItemCount() {         return mItems.size();     }      class ViewHolder extends RecyclerView.ViewHolder {          private int lastPosition = -1;         public ImageView imgThumbnail;         public TextView tvNature;         public TextView tvDesNature;        // Button btnclear,btncancle;         CardView card;         Activity activity;         Context co;         public ViewHolder(final View itemView) {             super(itemView);             imgThumbnail = (ImageView)     itemView.findViewById(R.id.img_thumbnail);             tvNature = (TextView) itemView.findViewById(R.id.tv_nature);             tvDesNature = (TextView) itemView.findViewById(R.id.tv_des_nature);             card = (CardView) itemView.findViewById(R.id.card);        card.setOnClickListener(new View.OnClickListener() {     @Override     public void onClick(View v) {          Toast.makeText(itemView.getContext(), "Clicked Card...", Toast.LENGTH_LONG).show();             ShareFragment newFragment = new ShareFragment();             FragmentTransaction transaction =  getFragmentManager().beginTransaction();             transaction.replace(R.id.viewFragments, newFragment);             transaction.addToBackStack(null);             transaction.commit();              }     });          }     } }

Open new fragment as follows in your onclick

@Override         public void onClick(View view){              AppCompatActivity activity = (AppCompatActivity) view.getContext();             Fragment myFragment = new MyFragment();             activity.getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, myFragment).addToBackStack(null).commit();           }
