I want to make an app with gridmenu in android studio. I have made a design, but i can`t make an intent activity with it. How can i make intent activity from Recyclerview and cardview from this code :

PlaylistAdapter.java :

public class PlaylistAdapter extends RecyclerView.Adapter<PlaylistViewHolder>

 private static final String TAG = PlaylistAdapter.class.getSimpleName();

 private Context context;
 private List<PlaylistObject> playlists;

 public PlaylistAdapter(Context context, List<PlaylistObject> playlists) 
 this.context = context;
 this.playlists = playlists;
 

 @Override
 public PlaylistViewHolder onCreateViewHolder(ViewGroup parent, int viewType) 
 View view = LayoutInflater.from(context).inflate(R.layout.play_list_layout, parent, false);
 return new PlaylistViewHolder(view);
 

 @Override
 public void onBindViewHolder(PlaylistViewHolder holder, int position) 
 PlaylistObject playlistObject = playlists.get(position);
 holder.playlistTitle.setText(playlistObject.getPlaylistTitle());
 holder.playlistCover.setImageResource(playlistObject.getPlaylistCover());

 

 @Override
 public int getItemCount() 
 return playlists.size();
 

PlaylistFragment.java :

public class PlaylistFragment extends Fragment 

 public PlaylistFragment() 
 

 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
 View view = inflater.inflate(R.layout.fragment_playlist, container, false);

 RecyclerView playlisRecyclerView = (RecyclerView)view.findViewById(R.id.your_play_list);
 GridLayoutManager gridLayout = new GridLayoutManager(getActivity(), 2);
 playlisRecyclerView.setLayoutManager(gridLayout);
 playlisRecyclerView.setHasFixedSize(true);

 PlaylistAdapter mAdapter = new PlaylistAdapter(getActivity(), getTestData());
 playlisRecyclerView.setAdapter(mAdapter);

 return view;
 

 public List<PlaylistObject> getTestData() 
 List<PlaylistObject> trackList = new ArrayList<PlaylistObject>();
 trackList.add(new PlaylistObject("My Account", "12 tracks", R.drawable.prf1));
 trackList.add(new PlaylistObject("My Teacher", "12 tracks", R.drawable.teacher));
 trackList.add(new PlaylistObject("Falling over", "12 tracks", R.drawable.album2));
 trackList.add(new PlaylistObject("Falling over", "12 tracks", R.drawable.album2));
 

fragment_playlist.xml :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="match_parent"

 android:layout_width="match_parent"
 android:layout_height="match_parent"

public class PlaylistAdapter extends RecyclerView.Adapter<PlaylistViewHolder> 

 private static final String TAG = PlaylistAdapter.class.getSimpleName();

 private Context context;
 private List<PlaylistObject> playlists;

 private OnItemClickListener mOnItemClickListener;

 public PlaylistAdapter(Context context, List<PlaylistObject> playlists) 
 this.context = context;
 this.playlists = playlists;
 

 // Set the click listener
 public void setOnItemClickListener(OnItemClickListener onItemClickListener) 
 mOnItemClickListener = onItemClickListener;
 

 @Override
 public PlaylistViewHolder onCreateViewHolder(ViewGroup parent, int viewType) 
 View view = LayoutInflater.from(context).inflate(R.layout.play_list_layout, parent, false);
 return new PlaylistViewHolder(view);
 

 @Override
 public void onBindViewHolder(PlaylistViewHolder holder, int position) 
 PlaylistObject playlistObject = playlists.get(position);
 holder.playlistTitle.setText(playlistObject.getPlaylistTitle());
 holder.playlistCover.setImageResource(playlistObject.getPlaylistCover());

 // Whole item
 holder.itemView.setOnClickListener(new View.OnClickListener 
 @Override
 public void onClick(View v) 
 if(mOnItemClickListener != null) 
 mOnItemClickListener.onItemClick();
 
 
 );

 // Or Title
 holder.playlistTitle.setOnClickListener(new View.OnClickListener 
 @Override
 public void onClick(View v) 
 if(mOnItemClickListener != null) 
 mOnItemClickListener.onItemClick();
 
 
 );

 // Or Cover
 holder.playlistCover.setOnClickListener(new View.OnClickListener 
 @Override
 public void onClick(View v) 
 if(mOnItemClickListener != null) 
 mOnItemClickListener.onItemClick();
 
 
 );
 

 @Override
 public int getItemCount() 
 return playlists.size();
 

 // The Item click listener
 public interface OnItemClickListener 

 void onItemClick();
 

Adapter add a OnItemClickListener, and Fragment implements this Listener

public class PlaylistFragment extends Fragment implements PlaylistAdapter.OnItemClickListener 

 public PlaylistFragment() 

 

 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
 View view = inflater.inflate(R.layout.fragment_playlist, container, false);

 RecyclerView playlisRecyclerView = (RecyclerView)view.findViewById(R.id.your_play_list);
 GridLayoutManager gridLayout = new GridLayoutManager(getActivity(), 2);
 playlisRecyclerView.setLayoutManager(gridLayout);
 playlisRecyclerView.setHasFixedSize(true);

 PlaylistAdapter mAdapter = new PlaylistAdapter(getActivity(), getTestData());

 // Set the click listener
 mAdapter.setOnItemClickListener(this);

 playlisRecyclerView.setAdapter(mAdapter);

 return view;
 

 public List<PlaylistObject> getTestData() 
 List<PlaylistObject> trackList = new ArrayList<PlaylistObject>();
 trackList.add(new PlaylistObject("My Account", "12 tracks", R.drawable.prf1));
 trackList.add(new PlaylistObject("My Teacher", "12 tracks", R.drawable.teacher));
 trackList.add(new PlaylistObject("Falling over", "12 tracks", R.drawable.album2));
 trackList.add(new PlaylistObject("Falling over", "12 tracks", R.drawable.album2));
 

 @Override
 public void onItemClick() 
 // Do what you want do
 //startActivity(new Intent(getActivity(), XXXXActivity.class));
