每個標籤由具有在recyclerview相同數據

-1

高科技大家我已經使用JSONS每個標籤包含其中該標籤的所需的數據，將顯示有再循環器視圖中創建的選項卡，但其中在輸出相同的數據在每一個標籤顯示和還一個項目在它顯示每個標籤由具有在recyclerview相同數據

JSON

適配器：

public class Recycler_Adapter extends RecyclerView.Adapter<ViewHolder> { 
    private Context context; 

    private List<TestPojo> list; 

    public Recycler_Adapter(Context context, List list) { 
     this.context = context; 
     this.list= list; 
    } 

    @Override 
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View namelist = LayoutInflater.from(parent.getContext()).inflate(R.layout.fragment_list_row, parent, false); 
     ViewHolder viewHolder = new ViewHolder(namelist); 
     return viewHolder; 
    } 

    @Override 
    public void onBindViewHolder(ViewHolder holder, int position) { 
     try { 
       TestPojo testpojo = list.get(position); 
       holder.cat_item_id.setText(testpojo.getId()); 
       holder.cat_item_name.setText(testpojo.getTitle()); 

     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 
    } 
    @Override 
    public int getItemCount() { 
     return list.length(); 
    } 
}

MainActivity.java

在TestFragment

public class MainActivity extends AppCompatActivity { 
    Toolbar toolbar; 
    TabLayout tabs; 
    ViewPager viewpager; 
    List<TestPojo> testlit; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 
     assert getSupportActionBar() != null; 
     getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
     tabs = (TabLayout) findViewById(R.id.tabs); 
     viewpager = (ViewPager) findViewById(R.id.viewpager); 
     testlit=new ArrayList<TestPojo>(); 
     catmethod(); 
    } 
    private void catmethod() { 
     String url = "http://www.souqalkhaleejia.com/webapis/categories.php"; 
     JsonObjectRequest catreq = new JsonObjectRequest(Request.Method.GET, url, (String) null, new Response.Listener<JSONObject>() { 
      @Override 
      public void onResponse(JSONObject response) { 
       try { 
        JSONArray menuarray = response.getJSONArray("menu1"); 
        for (int i = 0; i < menuarray.length(); i++) { 
         JSONObject menuobj = menuarray.getJSONObject(i); 
        tabs.addTab(tabs.newTab().setText(menuobj.getString("category"))); 
test.setTitlestring(itemobj.getString("title")); 
        } 
        } 
        TabsAdapter tabsAdapter = new TabsAdapter(getSupportFragmentManager(), menuarray); 
        viewpager.setAdapter(tabsAdapter); 
        tabs.setupWithViewPager(viewpager); 
       } catch (JSONException e) { 
        e.printStackTrace(); 
       } 

      } 
     }, new Response.ErrorListener() { 
      @Override 
      public void onErrorResponse(VolleyError error) { 
       Log.d("CatMenu", String.valueOf(error)); 
      } 
     }); 
     AppController.getInstance().addToRequestQueue(catreq); 
    } 
}

使用position：

private void catmethod() { 
      String url = "http://www.souqalkhaleejia.com/webapis/categories.php"; 
      int position = getArguments().getInt("position", 0); 
      JsonObjectRequest catreq = new JsonObjectRequest(Request.Method.GET, url, (String) null, new Response.Listener<JSONObject>() { 
       @Override 
       public void onResponse(JSONObject response) { 
        try { 
         JSONArray menuarray = response.getJSONArray("menu1"); 
          JSONObject menuobj = menuarray.getJSONObject(position); 
          JSONArray itemarray = menuobj.getJSONArray("items"); 
          List<TestPojo> objList = new ArrayList<>(); 
          for (int j = 0; j < itemarray.length(); j++) { 
           JSONObject itemobj = itemarray.getJSONObject(j); 
           TestPojo test = new TestPojo(); 
           test.setIdstring(itemobj.getString("id")); 
           test.setTitlestring(itemobj.getString("title")); 
           objList.add(test); 
          } 
          recycler_adapter = new Recycler_Adapter(getActivity(), objList); 
          recycler_view.setLayoutManager(new LinearLayoutManager(getActivity())); 
          recycler_view.setAdapter(recycler_adapter); 
          recycler_adapter.notifyDataSetChanged(); 
        } catch (JSONException e) { 
         e.printStackTrace(); 
        } 

       } 
      }, new Response.ErrorListener() { 
       @Override 
       public void onErrorResponse(VolleyError error) { 
        Log.d("CatMenu", String.valueOf(error)); 
       } 
      }); 
      AppController.getInstance().addToRequestQueue(catreq); 
     }

取出loop.Or你會得到所有的行顯示最後的數據。你應該在catmethod（）中使用getArguments（）。getInt（「position」，0）。

@Override 
public void onBindViewHolder(ViewHolder holder, int position) { 
    try { 
      String idname = jsonArray.getJSONObject(position).getString("id"); 
      String titlename = jsonArray.getJSONObject(position).getString("title"); 

      holder.cat_item_id.setText(idname); 
      holder.cat_item_name.setText(titlename); 
    } catch (JSONException e) { 
     e.printStackTrace(); 
    } 
}

代碼自爆應該只在TestFragment中使用一次，你不應該把它們放在循環中。

recycler_adapter = new Recycler_Adapter(getActivity(), itemarray); 
           recycler_view.setLayoutManager(new LinearLayoutManager(getActivity())); 
           recycler_view.setAdapter(recycler_adapter); 
           recycler_adapter.notifyDataSetChanged(); 


int position = getArguments().getInt("position", 0);

你在哪裏使用position.You得到這個位置，選擇什麼樣的數據在每個選項卡中顯示爲0 =>女性，1 =>小孩，2 =>男人。但你在哪裏使用它？請嘗試在TestFragment的catmethod中使用positoin。

不，先生沒有工作 – prominere

PLZ讀catmethod在TestFragment和寫入使用每一行的。 –

它不接受編輯先生 – prominere

每個標籤由具有在recyclerview相同數據
