如何在ontouch方法之后恢复recyclerview项目颜色

Question

我希望在点击回收器视图项后恢复为原来的颜色，如果之后我调用了thread.sleep并在此之后将textview颜色和imageview图像更改为原始图像然后没有显示更改一，它在完全执行touchlistener后显示输出是否有任何函数将在touchlistener之后执行

这是MyAdapter类

       Toast.makeText(context,"The Item Clicked is:       "+getPosition(),Toast.LENGTH_SHORT).show(); 


        Log.i("inside",String.valueOf(textView));
        }
        }


  MyAdapter(String Titles[],int Icons[],String Name,String Email, int    Profile)     { // MyAdapter Constructor with titles and icons parameter
                                    // titles, icons, name, email, profile pic are passed from the main activity as we

    //Below first we ovverride the method onCreateViewHolder which is called when the ViewHolder is

       @Override
          public MyAdapter.ViewHolder1 onCreateViewHolder(ViewGroup parent, int viewType) {

         if (viewType == TYPE_ITEM) {
         View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_row,parent,false); //Inflating the layout

          ViewHolder1 vhItem = new ViewHolder1(v,viewType, context); //Creating ViewHolder and passing the object of type view

         return vhItem; // Returning the created object

    //inflate your layout and pass it to view holder

         } else if (viewType == TYPE_HEADER) {

          View v =    LayoutInflater.from(parent.getContext()).inflate(R.layout.header,parent,false); //Inflating the layout

           ViewHolder1 vhHeader = new ViewHolder1(v,viewType,context); //Creating ViewHolder and passing the object of type view

       }
       return null;

         }

   //Next we override a method which is called when the item in a row is needed to be displayed, here the int position
  // Tells us item at which position is being constructed to be displayed and the holder id of the holder object tell us
  // which view type is being created 1 for item row
       @Override
        public void onBindViewHolder(MyAdapter.ViewHolder1 holder, int position)         {
         if(holder.Holderid ==1) {                              // as the list view is  going to be called after the header view so we decrement the
                                                      // position by 1 and pass it to the holder while setting the text and image
           holder.textView.setText(mNavTitles[position - 1]); // Setting the Text with the array of our Titles

           @Override
           public int getItemCount() {
           return mNavTitles.length+1; // the number of items in the list will be +1 the titles including the header view.
          }

         @Override
        public int getItemViewType(int position) {

          }

       private boolean isPositionHeader(int position) {
       return position == 0;
       }
     }

这是主要活动中的听众

    mRecyclerView.addOnItemTouchListener(new             RecyclerView.OnItemTouchListener() {


            @Override
              public boolean onInterceptTouchEvent(RecyclerView recyclerView, MotionEvent motionEvent) {
            View child = recyclerView.findChildViewUnder(motionEvent.getX(),motionEvent.getY());



            if(child!=null && mGestureDetector.onTouchEvent(motionEvent)){
              //Drawer.closeDrawers();
             Toast.makeText(home.this,"The Item Clicked is: "+recyclerView.getChildPosition(child),Toast.LENGTH_SHORT).show();
           // ImageView imageView1 = imageView;
            //TextView textView1 = textView;

            im = ((ViewHolder1) recyclerView.getTag()).imageView;
            te = ((ViewHolder1) recyclerView.getTag()).textView;
               im.setImageResource(ICONS2[(recyclerView.getChildPosition(child))-1]);
           te.setTextColor(Color.parseColor("#000000"));
           Log.i("text",String.valueOf(te.toString()));

              return true;
           }
          return false;
          }

附加图像是我点击后点击后应该像其他项目一样

Answer 1

我通过更改回收器视图的myadapter中的单击侦听器解决了我上面提到的问题

    holder.root.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
          holder.imageView.setImageResource(ICONS[position -1]);
         holder.textView.setTextColor(Color.parseColor("#FFFFFF"));
        }         
        });
        Log.i("position",String.valueOf(position));

    }

和主要活动中的触摸监听器如下。在onintercept触摸事件中写入以下代码

       if(txt!=null)
           {

                img.setImageResource(ICONS2[(recyclerView.getChildPosition(child)-1)]);
           txt.setTextColor(Color.parseColor("#000000"));}
