Question

我正在尝试在Recyclerview单个项目上实现Onclicklistner。我有点击单个项目时添加的功能功能是

我必须更改可绘制图像，文本视图颜色和视图的颜色边框。 2我还必须对布局隐藏一些看法，就像在Recyclerview的某些特定视图中没有显示按钮一样。我很难解决这个问题，请帮忙

这是我的RecyclerAdapter

    }



    @Override

        View view;
        LayoutInflater mInflater = LayoutInflater.from(context);

    }

    @Override

        holder.typeofGuest.setText(mData.get(position).getText());
        holder.guestImage.setImageResource(mData.get(position).getDrawable());
        holder.mLinearLayout.setOnClickListener(new View.OnClickListener() {

            mLinearLayout=itemView.findViewById(R.id.recycleritem_layout);
            typeofGuest = itemView.findViewById(R.id.guest_type);

                    click = false;
                } else {
                    typeofGuest.setTextColor(Color.parseColor("#000000"));

                    click = true;
                }


            }
        }
    }
}

我的模特课

public class DataModel {
    public String text;
    public boolean isSelected;


    public void setSelected(boolean selected) {
        isSelected = selected;
    }

    public int drawable;

    public DataModel(){

    }

    public DataModel(String text, int drawable) {
        this.text = text;
        this.drawable = drawable;
    }

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }

    public int getDrawable() {
        return drawable;
    }

    public void setDrawable(int drawable) {
        this.drawable = drawable;
    }

}

这是我的活动，我必须显示RecyclerView

public class AddVisitorActivity extends BaseActivity {
    List<DataModel>lsData;
    int spanCount = 3; // 3 columns
    int spacing = 50; // 50px
    boolean includeEdge = false;

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_add_visitor);
        lsData= new ArrayList<>();
        lsData.add(new DataModel("Guest",R.drawable.guest_two));
        lsData.add(new DataModel("Metting Room Booking",R.drawable.meetingroom_booking_two));
        lsData.add(new DataModel("Center Tour",R.drawable.centertour_two));
        lsData.add(new DataModel("House Keeping",R.drawable.housekeeping_two));
        lsData.add(new DataModel("Delivery",R.drawable.deliverytwo));
        lsData.add(new DataModel("Vendor",R.drawable.vendor_two));
        RecyclerView mRecyclerview= findViewById(R.id.rvNumbers);
        RecyclerViewAdapter mAdapter = new RecyclerViewAdapter(this,lsData);
        mRecyclerview.setLayoutManager(new GridLayoutManager(this,3));
        mRecyclerview.setAdapter(mAdapter);

        mRecyclerview.addItemDecoration(new SpacesItemDecoration(spanCount, spacing, includeEdge));
    }

}

Answer 1

如果项目数据不足以决定显示哪个，你可以考虑使用一个包装器ViewData类来保存项目数据和视图状态，如isButtonShown，imageUrl，......所以基于ViewData类，你可以决定ViewHolder的UI

单击recyclerview的单个视图并更改图标，文本颜色并使布局的某些部分可见且不可见
