recyclerviewのクリックリスナーに設定して静的ページを開き、json URLからコンテンツを取得する方法

Question

リサイクルビューの一連のアイテムがあります。クリックリスナーに設定して特定のアイテムの説明ページを開き、データを設定したいjson url。私はすでに説明画面とBeanクラス用のアダプタを作っています。私はレイアウト上でアダプタを設定する方法を知らない。 json urlからの静的コンテンツを表示するための線形レイアウトでアダプタを設定することは可能ですか？

私のコードは次のとおりです。

これは、URLからデータを取得するために使用され、私のコード（JSONデータであります）、アダプターを使ってrecyclerviewにロードし、同じ値を別のaに渡しますctivity。

MyActivity

public class Video_List extends AppCompatActivity { 
    private RecyclerView recyclerView; 
    private RecyclerView.LayoutManager layoutManager; 
    private RecyclerView.Adapter adapter; 
    //private GridLayoutManager layoutManager; 
    private List<Video_Details> videodetails; 
    public static final String VideoID = "v_id"; 
    public static final String ID = "id"; 
    public static final String Title = "title"; 
    public static final String Thumb = "thumb"; 
    public static final String url = "http://115.115.122.10/paul/api/videos.php?start=1&count=10"; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_video__list); 
     getdata(); 
     recyclerView = (RecyclerView) findViewById(R.id.card_recycler_view); 
     recyclerView.setHasFixedSize(true); 
     layoutManager = new LinearLayoutManager(this); 
     //layoutManager = new GridLayoutManager(this,2); 
     recyclerView.setLayoutManager(layoutManager); 
     videodetails = new ArrayList<>(); 



    } 
    private void getdata(){ 
     final ProgressDialog loading = ProgressDialog.show(this,"Loading Data", "Please wait...",false,false); 

     final JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(url, 
       new Response.Listener<JSONArray>() { 
        @Override 
        public void onResponse(JSONArray response) { 
         //Dismissing progress dialog 
         loading.dismiss(); 
         Log.d("count",response.toString()); 
         //calling method to parse json array 
         parseData(response); 
        } 
       }, 
       new Response.ErrorListener() { 
        @Override 
        public void onErrorResponse(VolleyError error) { 

         loading.dismiss(); 

         Log.d("infoz","777"+error.getMessage()); 

         Toast.makeText(getApplicationContext(),"No data Found",Toast.LENGTH_LONG).show(); 


        } 
       }); 

     //Creating request queue 
     RequestQueue requestQueue = Volley.newRequestQueue(this); 

     //Adding request to the queue 
     requestQueue.add(jsonArrayRequest); 
    } 

    //This method will parse json data 
    private void parseData(JSONArray array){ 

     try { 

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

       JSONObject json = array.getJSONObject(i); 

       Video_Details video = new Video_Details(); 

       if (json.has(VideoID)) { 
        Log.d("has values", json.getString(VideoID)); 
       } 
       video.setId(json.getString(ID)); 
       video.setV_id(json.getString(VideoID)); 
       video.setTitle(json.getString(Title)); 
       video.setThumb(json.getString(VideoID)); 
       videodetails.add(video); 

       if (json.has(VideoID)) 
       { 
        Log.d("Video",VideoID); 
       } 
      } 


     } catch (Exception e) { 
      e.printStackTrace(); 
     } 



     //Finally initializing our adapter 
     adapter = new DataAdapter(videodetails, this); 

     //Adding adapter to recyclerview 
     recyclerView.setAdapter(adapter); 



    }
