Question

我正在创建一个类似于聊天应用的应用。现在我不希望当前用户当前登录设备的帐户显示在FirebaseRecyclerAdapter结果列表中。我是当前用户的UID。现在我想从Adapter中仅过滤当前的UID。如果可能的话？提前谢谢。

这是我的FirebaseRecyclerAdapter代码

        FirebaseRecyclerAdapter<Donors, DonorsViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<Donors, DonorsViewHolder>(
            Donors.class,
            R.layout.donors_single_layout,
            DonorsViewHolder.class,
            mUsersDatabase.orderByChild("search").equalTo(searchKey)
    ) {

        @Override
        protected void populateViewHolder(DonorsViewHolder viewHolder, Donors model, int position) {

            viewHolder.setName(model.getName());
            viewHolder.setLocation(model.getLocation());
            viewHolder.setImage(model.getThumb_image(), getApplicationContext());
            viewHolder.setGroup(model.getGroup());

            final String donorID = getRef(position).getKey();

            //WANTED TO HIDE THIS WAY BUT THAT DOESN"T WORK :( 
            if(donorID == mCurrentUserId){
               viewHolder.setIsRecyclable(false);
                return;
            }

        }
    };

    mDonorsList.setAdapter(firebaseRecyclerAdapter);
    firebaseRecyclerAdapter.notifyDataSetChanged();

试试这个：

 viewHolder.setVisibility(View.INVISIBLE);

您的代码是这样的：

if(donorID == mCurrentUserId){
               viewHolder.setIsRecyclable(false);
               viewHolder.setVisibility(View.INVISIBLE);
                return;
            }

或：

viewHolder.setVisibility(View.GONE);

所以代码是这样的：

if(donorID == mCurrentUserId){ viewHolder.setIsRecyclable(false); viewHolder.setVisibility(View.GONE); return; }

如果Works隐藏了 itemview

隐藏FirebaseRecyclerAdapter中的值查看
