        </LinearLayout>
    </androidx.core.widget.NestedScrollView>
</androidx.coordinatorlayout.widget.CoordinatorLayout>

首先要完成这个列表数据的显示，这里还是会有item的布局和适配器，首先创建item的布局，在layout下新建一个item_trash_new_rv.xml。里面的代码如下：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="@dimen/dp_1"
    android:id="@+id/item_trash_news"
    android:foreground="?attr/selectableItemBackground"
    android:background="@color/white"
    android:orientation="vertical"
    android:padding="@dimen/dp_16">
    <!--标题-->
    <TextView
        android:id="@+id/tv_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:ellipsize="end"
        android:singleLine="true"
        android:text="标题"
        android:textColor="@color/black"
        android:textSize="@dimen/sp_16"
        android:textStyle="bold" />

    <!--内容描述-->
    <TextView
        android:id="@+id/tv_description"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/tv_title"
        android:layout_marginTop="@dimen/dp_8"
        android:text="内容描述"
        android:textColor="@color/black"
        android:textSize="@dimen/sp_14" />

</RelativeLayout>

然后就是适配器，在adapter下新建一个TrashNewsAdapter类，里面的代码如下：

package com.llw.goodtrash.adapter;

import androidx.annotation.Nullable;

import com.chad.library.adapter.base.BaseQuickAdapter;
import com.chad.library.adapter.base.BaseViewHolder;
import com.llw.goodtrash.R;
import com.llw.goodtrash.model.TrashNewsResponse;

import java.util.List;

/**
 * 垃圾分类新闻列表适配器
 *
 */
public class TrashNewsAdapter extends BaseQuickAdapter<TrashNewsResponse.NewslistBean, BaseViewHolder> {

    public TrashNewsAdapter(int layoutResId, @Nullable List<TrashNewsResponse.NewslistBean> data) {
        super(layoutResId, data);
    }

    @Override
    protected void convert(BaseViewHolder helper, TrashNewsResponse.NewslistBean item) {
        helper.setText(R.id.tv_title, item.getTitle())
                .setText(R.id.tv_description, item.getDescription())
                .addOnClickListener(R.id.item_trash_news);
    }
}

/**
     * 页面初始化
     */
    private void initView() {
        banner = findViewById(R.id.banner);
        collapsingToolbarLayout = findViewById(R.id.toolbar_layout);
        appBarLayout = findViewById(R.id.appbar_layout);
        rvNews = findViewById(R.id.rv_news);

        //伸缩偏移量监听
        appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
            boolean isShow = true;
            int scrollRange = -1;

            @Override
            public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
                if (scrollRange == -1) {
                    scrollRange = appBarLayout.getTotalScrollRange();
                }
                if (scrollRange + verticalOffset == 0) {//收缩时
                    collapsingToolbarLayout.setTitle("垃圾分类");
                    isShow = true;
                } else if (isShow) {//展开时
                    collapsingToolbarLayout.setTitle("");
                    isShow = false;
                }
            }
        });
        //设置列表
        mAdapter = new TrashNewsAdapter(R.layout.item_trash_new_rv, mList);
        mAdapter.setOnItemChildClickListener((adapter, view, position) -> {
            showMsg("点击了第" + position + "个");
        });
        rvNews.setLayoutManager(new LinearLayoutManager(context));
        rvNews.setAdapter(mAdapter);
        //请求垃圾分类新闻数据
        mPresenter.getTrashNews(10);
    }
