用recyclerReview展示Banner,很简单

不废话,直接上图 

 1.布局随便

<androidx.recyclerview.widget.RecyclerView
                    android:id="@+id/recycler_emigrates"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:orientation="horizontal"
                    android:overScrollMode="never"
                    app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
                    app:layout_constraintTop_toBottomOf="@+id/tv_emigrates_more"
                    tools:layout_editor_absoluteX="0dp" />

2. 打造水平 ItemDecorationHorizontal

import android.graphics.Rect;
import android.view.View;

import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;

import com.xx.common.utils.ScreenUtil;

public class ItemDecorationHorizontal extends RecyclerView.ItemDecoration {

    private int left;
    private int top;
    private int right;
    private int bottom;
    private int first;

    public ItemDecorationHorizontal(int left, int top, int right, int bottom) {
        this.left = (int) ScreenUtil.dp2px(left);
        this.top = (int) ScreenUtil.dp2px(top);
        this.right = (int) ScreenUtil.dp2px(right);
        this.bottom = (int) ScreenUtil.dp2px(bottom);
    }

    public ItemDecorationHorizontal(int first, int left, int top, int right, int bottom) {
        this.first = (int) ScreenUtil.dp2px(first);
        this.left = (int) ScreenUtil.dp2px(left);
        this.top = (int) ScreenUtil.dp2px(top);
        this.right = (int) ScreenUtil.dp2px(right);
        this.bottom = (int) ScreenUtil.dp2px(bottom);
    }

    @Override
    public void getItemOffsets(@NonNull Rect outRect, @NonNull View view, @NonNull RecyclerView parent, @NonNull RecyclerView.State state) {
        super.getItemOffsets(outRect, view, parent, state);
        int left = this.left;
        if (first > 0) {
            int position = ((RecyclerView.LayoutParams) view.getLayoutParams()).getViewLayoutPosition();
            if (position == 0)
                left += first;
        }
        outRect.set(left, top, right, bottom);
    }
}

3.配置

 emigratesList = new ArrayList<>();
        emigratesAdapter = new EmigratesAdapter(getContext(), emigratesList);
        binding.recyclerEmigrates.addItemDecoration(new ItemDecorationHorizontal(12, 0, 0, 12, 0));
        binding.recyclerEmigrates.setHasFixedSize(true);
        binding.recyclerEmigrates.setAdapter(emigratesAdapter);

//请求接口成功后,填充数据
//刷新适配器

 emigratesList.addAll(data.getHwEmigrates());
 emigratesAdapter.notifyDataSetChanged();

4.Adapter ,没有用Bindding的,自己修改下就好了

import android.content.Context;
import android.view.LayoutInflater;
import android.view.ViewGroup;

import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;

import com.alibaba.android.arouter.launcher.ARouter;
import com.bumptech.glide.Glide;
import com.google.gson.Gson;
import com.xx.common.bean.ListString;
import com.xx.common.bean.NationalProjectDto;
import com.xx.common.route.RoutePath;
import com.xx.module.club365.R;
import com.xx.module.club365.databinding.AdapterEmigratesBinding;
import com.xx.module.club365.databinding.BannerAdapterItemBinding;

import java.util.List;

public class EmigratesAdapter extends RecyclerView.Adapter {

    private Context mContext;
    private List<NationalProjectDto> mList;
    private LayoutInflater mInflater;

    public EmigratesAdapter(Context context, List<NationalProjectDto> list) {
        this.mContext = context;
        this.mList = list;
        mInflater = LayoutInflater.from(mContext);
    }

    @Override
    public int getItemViewType(int position) {
        return 0;
    }

    @NonNull
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        RecyclerView.ViewHolder holder;
        AdapterEmigratesBinding binding = AdapterEmigratesBinding.inflate(mInflater, parent, false);

        holder = new EmigratesHolder(binding);
        holder.itemView.setOnClickListener(v -> {
            int position = holder.getAdapterPosition();
            ARouter.getInstance().build(RoutePath.IMMIGRANT_INFO)
                    .withString("telephone",mList.get(position).getTelephone())
                    .withString("images", new Gson().toJson(new ListString(mList.get(position).getImages())))
                    .navigation();
        });
        return holder;
    }

    @Override
    public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) {

        ((EmigratesHolder) holder).binding.brief.setText(mList.get(position).getBrief());
        ((EmigratesHolder) holder).binding.name.setText(mList.get(position).getName());

        Glide.with(mContext).load(mList.get(position).getImage()).placeholder(R.drawable.icon_def)
                .error(R.drawable.icon_def).into(((EmigratesHolder) holder).binding.image);
    }

    @Override
    public int getItemCount() {
        return mList == null ? 0 : mList.size();
    }

    class EmigratesHolder extends RecyclerView.ViewHolder {

        AdapterEmigratesBinding binding;

        public EmigratesHolder(@NonNull AdapterEmigratesBinding binding) {
            super(binding.getRoot());
            this.binding = binding;
        }
    }

}

5.adapter布局 布局的大小写法很重要(注意)
