每个标签由具有在recyclerview相同数据

-1

高科技大家我已经使用JSONS每个标签包含其中该标签的所需的数据，将显示有再循环器视图中创建的选项卡，但其中在输出相同的数据在每一个标签显示和还一个项目在它显示每个标签由具有在recyclerview相同数据

JSON

适配器：

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你会得到所有的行显示最后的数据。你应该在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(); 
    } 
}

代码自爆应该只在TestFragment中使用一次，你不应该把它们放在循环中。

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);

你在哪里使用position.You得到这个位置，选择什么样的数据在每个选项卡中显示为0 =>女性，1 =>小孩，2 =>男人。但你在哪里使用它？请尝试在TestFragment的catmethod中使用positoin。

不，先生没有工作 – prominere

PLZ读catmethod在TestFragment和写入使用每一行的。 –

它不接受编辑先生 – prominere

每个标签由具有在recyclerview相同数据
