Ausblenden eines Relaylayouts in Recyclerview

Question

Ich verwende dieses Liabray für Swipe-Gesten. https://github.com/nikhilpanju/RecyclerViewEnhanced.

Aktivität:

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_admin_panel); 
     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 


     unclickableRows = new ArrayList<>(); 
     unswipeableRows = new ArrayList<>(); 
     dialogItems = new String[25]; 
     for (int i = 0; i < 25; i++) { 
      dialogItems[i] = String.valueOf(i + 1); 
     } 

     mRecyclerView = (RecyclerView) findViewById(R.id.recyclerView); 
     mAdapter = new MainAdapter(this, getData()); 
     mRecyclerView.setAdapter(mAdapter); 
     mRecyclerView.setLayoutManager(new LinearLayoutManager(this)); 

     onTouchListener = new RecyclerTouchListener(this, mRecyclerView); 
     onTouchListener 
       .setIndependentViews(R.id.rowButton) 
       .setViewsToFade(R.id.rowButton) 
       .setClickable(new RecyclerTouchListener.OnRowClickListener() { 
        @Override 
        public void onRowClicked(int position) { 
         util.shortToast(getApplicationContext(), "Row " + (position + 1) + " clicked!"); 
        } 

        @Override 
        public void onIndependentViewClicked(int independentViewID, int position) { 
         util.shortToast(getApplicationContext(), "Button in row " + (position + 1) + " clicked!"); 
        } 
       }) 
       .setSwipeOptionViews(R.id.add, R.id.edit, R.id.change) 
       .setSwipeable(R.id.rowFG, R.id.rowBG, new RecyclerTouchListener.OnSwipeOptionsClickListener() { 
        @Override 
        public void onSwipeOptionClicked(int viewID, int position) { 
         String message = ""; 
         if (viewID == R.id.add) { 
          message += "Add"; 
         } else if (viewID == R.id.edit) { 
          message += "Edit"; 
         } else if (viewID == R.id.change) { 
          message += "Change"; 
         } 
         message += " clicked for row " + (position + 1); 
         util.shortToast(getApplicationContext(), message); 
        } 
       }); 
     mRecyclerView.addOnItemTouchListener(onTouchListener); 

Im folgenden Code, ich will ein Relativelayout verstecken, wenn in onSwipeOptionclicked() gibt die viewId == R.id.add. Ich habe Code geändert, um eine Referenz zu erhalten, weiß aber nicht, was ich als nächstes tun soll.

.setSwipeOptionViews(R.id.add, R.id.edit, R.id.change) 
        .setSwipeable(R.id.rowFG, R.id.rowBG, new RecyclerTouchListener.OnSwipeOptionsClickListener() { 
         @Override 
         public void onSwipeOptionClicked(int viewID, int position) { 
          if (viewID == R.id.add) { 
          } 
         } 
        }); 

Modified Code:

.setSwipeOptionViews(R.id.add, R.id.edit, R.id.change) 
         .setSwipeable(R.id.rowFG, R.id.rowBG, new RecyclerTouchListener.OnSwipeOptionsClickListener() { 
          @Override 
          public void onSwipeOptionClicked(int viewID, int position) { 
           if (viewID == R.id.add) { 


RelativeLayout username = (RelativeLayout) view.findViewById(R.id.add); 
           } 
          } 
         });
