How to launch another activity by clicking on cardview?

I have a Recyclerview with Cardview s that show an image and a short description that is obtained through a JSON (with volley ), what I want is that, when I click on an item from the recycler all the information is opened together with the image but I do not know how, I do not know if to use an activity or a fragment and obviously each item must open its respective description

MainActivity

public class MainActivity extends AppCompatActivity {
    private Toolbar mToolbar;
    RequestQueue queue;
    String url = "http://urljson";
    RecyclerView recyclerView;
    List<NewsFeed> feedsList = new ArrayList<NewsFeed>();
    MyRecyclerAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //initialize toolbar
        mToolbar = (Toolbar)findViewById(R.id.toolbar);
        setSupportActionBar(mToolbar);
        getSupportActionBar().setDisplayShowHomeEnabled(true);
        //Initialize RecyclerView
        recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
        adapter = new MyRecyclerAdapter(this, feedsList);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));

        recyclerView.setAdapter(adapter);
        //Scroll-hide
        recyclerView.setOnScrollListener(new MyScrollListener(this) {
            @Override
            public void onMoved(int distance) {
                mToolbar.setTranslationY(-distance);
            }
            //Scroll-hide
        });
        //Getting Instance of Volley Request Queue
        queue = NetworkController.getInstance(this).getRequestQueue();
        //Volley's inbuilt class to make Json array request
        JsonArrayRequest newsReq = new JsonArrayRequest(url, new Response.Listener<JSONArray>() {
            @Override
            public void onResponse(JSONArray response) {

                for (int i = 0; i < response.length(); i++) {
                    try {

                        JSONObject obj = response.getJSONObject(i);
                        NewsFeed feeds = new NewsFeed(obj.getString("title"), obj.getString("content"), obj.getString("image"));

                        // adding movie to movies array
                        feedsList.add(feeds);

                    } catch (Exception e) {
                        System.out.println(e.getMessage());
                    } finally {
                        //Notify adapter about data changes
                        adapter.notifyItemChanged(i);
                    }
                }
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                System.out.println(error.getMessage());
            }
        });
        //Adding JsonArrayRequest to Request Queue
        queue.add(newsReq);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }


    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

}

AdapterRecycler

public class MyRecyclerAdapter extends    RecyclerView.Adapter<MyRecyclerAdapter.MyViewHolder> {

    private List<NewsFeed> feedsList;
    private Context context;
    private LayoutInflater inflater;

    public MyRecyclerAdapter(Context context, List<NewsFeed> feedsList) {

        this.context = context;
        this.feedsList = feedsList;
        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        View rootView = inflater.inflate(R.layout.singleitem_recyclerview, parent, false);
        return new MyViewHolder(rootView);
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {
        NewsFeed feeds = feedsList.get(position);
        //Pass the values of feeds object to Views
        holder.title.setText(feeds.getFeedName());
        holder.content.setText(feeds.getContent());
        holder.imageview.setImageUrl(feeds.getImgURL(), NetworkController.getInstance(context).getImageLoader());
    }

    @Override
    public int getItemCount() {
        return feedsList.size();
    }

    public class MyViewHolder extends RecyclerView.ViewHolder {

        private TextView content, title;
        private NetworkImageView imageview;

        public MyViewHolder(View itemView) {
            super(itemView);
            title = (TextView) itemView.findViewById(R.id.title_view);
            content = (TextView) itemView.findViewById(R.id.content_view);
            // Volley's NetworkImageView which will load Image from URL
            imageview = (NetworkImageView) itemView.findViewById(R.id.thumbnail);
            itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    Toast.makeText(context, "msg msg", Toast.LENGTH_SHORT).show();
                }
            });

        }
