添加给需要项目的依赖

implementation 'com.github.CymChad:BaseRecyclerViewAdapterHelper:2.9.42' implementation 'com.android.support:recyclerview-v7:28.0.0'

万能适配器的代码

package com.example.administrator.myapplication;

import android.content.Context;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v7.widget.RecyclerView;
import android.widget.ImageView;

import com.bumptech.glide.Glide;
import com.chad.library.adapter.base.BaseQuickAdapter;
import com.chad.library.adapter.base.BaseViewHolder;

import java.util.List;

public class MyApter extends BaseQuickAdapter<Bean1.DataEntity,BaseViewHolder>{
    Context context;

    public MyApter(int layoutResId, @Nullable List<Bean1.DataEntity> data, Context context) {
        super(layoutResId, data);
        this.context=context;
    }

    @Override
    protected void convert(BaseViewHolder helper, Bean1.DataEntity item) {
        helper.setText(R.id.tv,item.getTitle());
        Glide.with(context).load(item.getPic()).into((ImageView) helper.getView(R.id.iv));
    }
}

package com.example.administrator.myapplication;

        OkGo.<String>get("http://www.qubaobei.com/ios/cf/dish_list.php?stage_id=1&limit=200&page=1").execute(new StringCallback() {

                String body = response.body();
                Bean1 bean1 = new Gson().fromJson(body, Bean1.class);

                recyclerView.setLayoutManager(linearLayoutManager);
             myApter1.notifyDataSetChanged();


            }

            @Override
            public void downloadProgress(Progress progress) {
                super.downloadProgress(progress);
                int fraction = (int)progress.fraction;
            }
        });

    }
