这是我的活动，我必须在其中显示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));
    }

}

public类AddVisitorActivity扩展了BaseActivity{
列表数据；
int spanCount=3；//3列
int间距=50；//50px
布尔includeEdge=false；
@凌驾
创建时的公共void（@Nullable Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（R.layout.activity\u add\u visitor）；
lsData=newarraylist（）；
添加（新的数据模型（“Guest”，R.drawable.Guest_-two））；
lsData.add（新的数据模型（“会议室预订”，R.drawable.meetingroom_Booking_two））；
添加（新的数据模型（“中心漫游”，R.drawable.centertour_two））；
添加（新的数据模型（“House-Keeping”，R.drawable.housing_-two））；
添加（新的数据模型（“Delivery”，R.drawable.deliverytwo））；
添加（新的数据模型（“供应商”，R.drawable.Vendor_two））；
RecyclerView mRecyclerview=findViewById（R.id.RVNumber）；
RecycleServiceAdapter mAdapter=新的RecycleServiceAdapter（此为lsData）；
setLayoutManager（新的GridLayoutManager（this，3））；
mRecyclerview.setAdapter（mAdapter）；
mRecyclerview.addItemDecoration（新的SpacesItemDecoration（跨度、间距、包括边缘））；

如果项目数据不足以决定要显示哪个，则可以考虑使用包含项目数据和视图状态的包装器VIEWDATA类，如ISButon Studio、IVIULL、…因此，根据ViewData类，您可以决定ViewHolder的UI
难道您不能至少有礼貌地显示您已经完成的工作吗？如果没有任何代码测试，您的问题的上下文将变得过于宽泛而无法感知。是的，确定我在共享我正在显示可绘图文件夹中的图像，而不是url中的图像
