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); }
