回收站查看錯誤地選擇查看項目同時進行多選擇

我已經實現與多選成功地利用addOnItemTouchListener識別和使用的單人和雙人click.When我已經不到5項詮釋的回收來看，一切正常選擇回收視圖很好，但是當我有更多的數據時，確切地說，當回收視圖開始回收視圖時，我的選擇會變得瘋狂，並且它會選擇不同的位置。我退出以查看點擊位置，這些看起來是正確的，但是某些不正確這使我的選擇wrong.I'm新的編程和Android應用development.Can任何人在這個很多參加並幫我請，這裏是我的代碼回收站查看錯誤地選擇查看項目同時進行多選擇

我的適配器類

public class ContactAdapter extends RecyclerView.Adapter<ContactAdapter.ContactHolder> implements SectionIndexer, Filterable { 

    public List<Contact> contactList; 
    List<Contact> filteredUsersList; 
    CustomFilter filter; 
    Context mContext; 
    int itemResource; 
    ArrayList<Contact> selected_usersList = new ArrayList<>(); 
    int pos; 

    private ArrayList<Integer> mSectionPositions; 

    ContactAdapter(Context mContext, int itemResource, List<Contact> contactList, ArrayList<Contact> selectedList) { 
     this.contactList = contactList; 
     this.mContext = mContext; 
     this.itemResource = itemResource; 
     this.selected_usersList = selectedList; 
     this.filteredUsersList = contactList; 
    } 

    @Override 
    public ContactHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View v = LayoutInflater.from(parent.getContext()).inflate(itemResource, parent, false); 
     return new ContactHolder(v); 
    } 

    @Override 
    public void onBindViewHolder(final ContactHolder holder, int position) { 
     pos = position; 
     final Contact contact = contactList.get(pos); 

     holder.colg.setText(contact.getColg()); 
     holder.name.setText(contact.getName()); 
     holder.job.setText(contact.getJob()); 


     if (contact.getImage() != null) 
      holder.img.setImageBitmap(Utility.getPhoto(contact.getImage())); 


    } 

    @Override 
    public int getItemCount() { 
     return this.contactList.size(); 
    } 


    class ContactHolder extends RecyclerView.ViewHolder { 

     private TextView name, colg, job, id, mentee, mentor, participant; 
     private ImageView selected; 
     // private PorterShapeImageView img; 
     private HexagonMaskView img; 
     private RelativeLayout rr_layout; 
     ItemClickListener itemClickListener; 

     ContactHolder(View itemView) { 
      super(itemView); 
      // Set up the UI widgets of the holder 
      // img = (PorterShapeImageView) itemView.findViewById(R.id.contact_image); 
      img = (HexagonMaskView) itemView.findViewById(R.id.contact_image); 
      name = (TextView) itemView.findViewById(R.id.contact_name); 
      colg = (TextView) itemView.findViewById(R.id.contact_colg); 
      job = (TextView) itemView.findViewById(R.id.contact_job); 
      mentee = (TextView) itemView.findViewById(R.id.mentee); 
      mentor = (TextView) itemView.findViewById(R.id.mentor); 
      participant = (TextView) itemView.findViewById(R.id.participant); 
      rr_layout = (RelativeLayout) itemView.findViewById(R.id.rr_layout); 
      selected = (ImageView) itemView.findViewById(R.id.tic_contact_selected); 

     } 

    } 
}

我RecyclerItemClickListener類

public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener { 

    public interface OnItemClickListener { 
     void onItemClick(View view, int position); 

     void onItemLongClick(View view, int position); 
    } 

    private OnItemClickListener mListener; 
    private GestureDetector mGestureDetector; 

    public RecyclerItemClickListener(Context context, final RecyclerView recyclerView, OnItemClickListener listener) { 
     mListener = listener; 

     mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() { 
      @Override 
      public boolean onSingleTapUp(MotionEvent e) { 
       return true; 
      } 

      @Override 
      public void onLongPress(MotionEvent e) { 
       View childView = recyclerView.findChildViewUnder(e.getX(), e.getY()); 

       if (childView != null && mListener != null) { 
        mListener.onItemLongClick(childView, recyclerView.getChildAdapterPosition(childView)); 
       } 
      } 
     }); 
    } 

    @Override 
    public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) { 
     View childView = view.findChildViewUnder(e.getX(), e.getY()); 

     if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) { 
      mListener.onItemClick(childView, view.getChildAdapterPosition(childView)); 
     } 

     return false; 
    } 

    @Override 
    public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) { 
    } 

    @Override 
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) { 

    } 
}

我addOnItemTouchListener實施

contactsRecyclerViewT.addOnItemTouchListener(new RecyclerItemClickListener(this, contactsRecyclerViewT, new RecyclerItemClickListener.OnItemClickListener() { 
     @Override 
     public void onItemClick(View view, final int position) { 

      Log.e("tag", "" + position); 

      for (int i = 0; i < multiselect_list.size(); i++) { 
       Log.e("tag", "sss" + multiselect_list.get(i).getName()); 
      } 

      pos = position; 

      contact = contactArrayList.get(position); 

      menteeTextView = (TextView) view.findViewById(R.id.mentee);

您應該添加你的邏輯在onBindViewHolder不onItemClick –

能否請您詳細說明和賜教請@MuthukrishnanRajendran –

RecyleView始終重用視圖，您將所有的onItemClick但是當你開始滾動的新對象將創建或現有對象將修改以完成新項目。那麼請更好地對onBindViewHolder進行所有更改。 –

你正在做的大部分的onclick聽衆認爲操縱的，你應該適配器onBindView移動您來決定，因爲即使您在Onclick監聽器中設置，它將在用戶滾動時進行修改。

我不會放棄完整視圖操作，我只是給的提示，我們應該怎麼做。

@Override 
public void onBindViewHolder(final ContactHolder holder, int position) { 
    pos = position; 
    final Contact contact = contactList.get(pos); 

    holder.colg.setText(contact.getColg()); 
    holder.name.setText(contact.getName()); 
    holder.job.setText(contact.getJob()); 


    if (contact.getImage() != null) 
     holder.img.setImageBitmap(Utility.getPhoto(contact.getImage())); 


    if (multiselect_list.contains(contactArrayList.get(position))) { // May be you should check form your fragment or actvity using listeners 
     holder.mentee.setBackgroundColor(ContextCompat.getColor(ContactsActivity.this, R.color.colorPrimary)); 
     holder.participant.setBackgroundColor(ContextCompat.getColor(ContactsActivity.this, R.color.colorPrimary)); 

     holder.mentee.setVisibility(View.VISIBLE); 
     holder.participant.setVisibility(View.VISIBLE); 
    } else { 

     holder.mentee.setVisibility(View.GONE); 
     holder.participant.setVisibility(View.GONE); 
    } 

}

所以所有的點擊收聽邏輯應該內onBindViewHolder wriiten呃？那麼我的addOnItemTouchListener實現中應該包含什麼 –

yes對於每個項目中的視圖，您應該添加到onBindViewHolder（ex menteeTextView.setOnClickListener）中，但是對於完整的項目，您可以使用RecycleViewClickListener。 –

裏面addOnItemTouchListener你可以添加或刪除到multiselect_list，只是調用notifyDataSetChange它會更新onBindViewHolder中的視圖 –

添加boolena陣列

初始化構造機智ArrayList中。

itemcheck = new boolean[feedItemList.size()];

在bindview持有人檢查這樣

if(itemcheck[position]==true){ 
    holder.row_linearlayout.setBackgroundColor(Color.parseColor("#b7c5ea")); 
     }else { 
      holder.row_linearlayout.setBackgroundColor(0xFFFFFFFF); 
      //holder.row_linearlayout.setBackgroundResource(R.drawable.blurback); 
     }

，並設置問題還是你的RelativeLayout CONTROLE，而不是任何其他CONTROLE虛假的onclick。

holder.row_linearlayout.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        LinearLayout Lout = (LinearLayout) v.findViewById(R.id.selectlinear); 
        if(model.isSelected()){ 
         Lout.setBackgroundColor(0xFFFFFFFF); 
         itemcheck[position]=false; 
         //get all other controle value here 
        }else{ 

         Lout.setBackgroundColor(Color.parseColor("#b7c5ea")); 
         itemcheck[position]=true;  
         //get all other controle value here     
        } 
       } 
      });
