在单独的视图中过滤搜索

Question

您好，我有一个类似于以下image的菜单标签，在这里我需要过滤回收站中的产品。因此，现在有了在活动中进行搜索的工具栏，并在片段中添加了我需要过滤的回收者，当使用过滤来获取片段中的内容时，我就会停滞不前，可以通过某种方式在两者之间进行交互并可以执行我的过滤。

我的活动菜单标签

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_products1);
    showToolbar("Productos", true);


    TabLayout tabLayout = (TabLayout) findViewById(R.id.tabLayout);
    tabLayout.addTab(tabLayout.newTab().setText("Productos"));
    tabLayout.addTab(tabLayout.newTab().setText("Combos"));

    searchView = (MaterialSearchView) findViewById(R.id.search_view);

    final ViewPager viewPager = (ViewPager) findViewById(R.id.viewPager1);
    PagerAdapter adapter = new ViewPagerAdapter1(getSupportFragmentManager(), tabLayout.getTabCount());


    viewPager.setAdapter(adapter);
    viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));

    searchView.setOnQueryTextListener(new MaterialSearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            //Do some magic
            Log.w("TAG", "Click1");
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            //Do some magic
            Log.w("TAG", "Click2");
            return false;
        }
    });

    searchView.setOnSearchViewListener(new MaterialSearchView.SearchViewListener() {
        @Override
        public void onSearchViewShown() {
            //Do some magic
            showToolbar("", false);
            Log.w("TAG", "Click3");
        }

        @Override
        public void onSearchViewClosed() {
            Log.w("TAG", "Click4");
            showToolbar("Productos", true);

            //Do some magic
        }
    });

    tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            int position = tab.getPosition();
            viewPager.setCurrentItem(position);
        }

        @Override
        public void onTabUnselected(TabLayout.Tab tab) {
            // Toast.makeText(Products1Activity.this, "Unselected -> "+tab.getText(), Toast.LENGTH_SHORT).show();
            SendParametro();
        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {
            //  Toast.makeText(Products1Activity.this, "Reselected -> "+tab.getText(), Toast.LENGTH_SHORT).show();
            SendParametro();
        }
    });
}

我的Fragmet回收站：

@Override
   public View onCreateView(LayoutInflater inflater, ViewGroup container,
                            Bundle savedInstanceState) {

       showProgressDialog();
       rootView = inflater.inflate(R.layout.fragment_products, container, false);

       addMyCart = (Button) rootView.findViewById(R.id.addMyCart);
       db = FirebaseDatabase.getInstance().getReference();
       user = FirebaseAuth.getInstance().getCurrentUser();
       MycategoriesCard = new ArrayList<MyCartProducts>();
       gson = new Gson();
       preferences = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
       String savedList = preferences.getString("MyProductsCardList","");
       Type type = new TypeToken<List<MyCartProducts>>(){}.getType();
       MyProductsCardList = gson.fromJson(savedList,type);

       mMyProducts = new ArrayList<>();
       mMyProducts = this.getAllProducts();

       mRecyclerView = (RecyclerView) rootView.findViewById(R.id.recycler_products);
       mLayoutManager = new LinearLayoutManager(getContext());

      mAdapter = new MyAdapterProducts1(mMyProducts, R.layout.my_recycler_products1, new MyAdapterProducts1.OnItemClickListener() {
           @Override
           public void onItemClick(MyProducts myProducts, int position) {

           }

          @Override
          public void onClickMore(MyProducts myProducts, int position, int contadorProd, String name, double soles) {

          }

          public void onClickLess(int contadorProd) {
              String cadena = Integer.toString(contadorProd);
              text_count.setText(cadena);
          }


          public void onClickReservar(int contadorProd) {
              String cadena = Integer.toString(contadorProd);
              text_count.setText(cadena);
              Log.w(TAG,"contadorProd: " + contadorProd);
          }

       });

       mRecyclerView.setHasFixedSize(true);
       mRecyclerView.setItemAnimator(new DefaultItemAnimator());
       mRecyclerView.setLayoutManager(mLayoutManager);
       mRecyclerView.setAdapter(mAdapter);

       return rootView;
   }
