一 ListView

以常被RecyclerView代替，用时遗忘可翻阅以下文章：

二 RecyclerView

adapter代码:

public class FruitAdapter extends RecyclerView.Adapter<FruitAdapter.ViewHolder>{

    private List<Fruit> mFruitList;

    static class ViewHolder extends RecyclerView.ViewHolder {
        View fruitView;
        ImageView fruitImage;
        TextView fruitName;

        public ViewHolder(View view) {
            super(view);
            fruitView = view;
            fruitImage = (ImageView) view.findViewById(R.id.fruit_image);
            fruitName = (TextView) view.findViewById(R.id.fruit_name);
        }
    }

    public FruitAdapter(List<Fruit> fruitList) {
        mFruitList = fruitList;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.fruit_item, parent, false);
        final ViewHolder holder = new ViewHolder(view);
        holder.fruitView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int position = holder.getAdapterPosition();
                Fruit fruit = mFruitList.get(position);
                Toast.makeText(v.getContext(), "you clicked view " + fruit.getName(), Toast.LENGTH_SHORT).show();
            }
        });
        holder.fruitImage.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int position = holder.getAdapterPosition();
                Fruit fruit = mFruitList.get(position);
                Toast.makeText(v.getContext(), "you clicked image " + fruit.getName(), Toast.LENGTH_SHORT).show();
            }
        });
        return holder;
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        Fruit fruit = mFruitList.get(position);
        holder.fruitImage.setImageResource(fruit.getImageId());
        holder.fruitName.setText(fruit.getName());
    }

    @Override
    public int getItemCount() {
        return mFruitList.size();
    }

}

列表（数据源）：

private List<Fruit> fruitList = new ArrayList<Fruit>();

activity中的代码：

常版本：

RecyclerView recyclerView=(RecyclerView)findViewById(R.id.recyclerView);
LinearLayoutManager layoutManager=new LinearLayoutManager(this);//线性布局
recyclerView.setLayoutManager(layoutManager);
VegeAdapterSecond vegeAdapterSecond=new VegeAdapterSecond(vegetableList);
recyclerView.setAdapter(vegeAdapterSecond);

瀑布流：

initFruits();
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
StaggeredGridLayoutManager layoutManager = new
                StaggeredGridLayoutManager(3, StaggeredGridLayoutManager.VERTICAL);
recyclerView.setLayoutManager(layoutManager);
FruitAdapter adapter = new FruitAdapter(fruitList);
recyclerView.setAdapter(adapter);

三 轮子推荐

3.1 ​​BRVAH​​

详细可看作者文章：​​https://www.jianshu.com/p/b343fcff51b0​​

先在 build.gradle(Project:XXXX) 的 repositories 添加:

allprojects {
        repositories {
            ...
            maven { url "https://jitpack.io" }
        }
    }

然后在 build.gradle(Module:app) 的 dependencies 添加:

dependencies {
            compile 'com.github.CymChad:BaseRecyclerViewAdapterHelper:2.9.30'
    }

更新说明：​​https://github.com/CymChad/BaseRecyclerViewAdapterHelper/releases​​

adapter：

public class HomeAdapter extends BaseQuickAdapter<HomeItem, BaseViewHolder> {
    public HomeAdapter(int layoutResId, List data) {
        super(layoutResId, data);
    }

    @Override
    protected void convert(BaseViewHolder helper, HomeItem item) {
        helper.setText(R.id.text, item.getTitle());
        helper.setImageResource(R.id.icon, item.getImageResource());
        // 加载网络图片
      Glide.with(mContext).load(item.getUserAvatar()).crossFade().into((ImageView) helper.getView(R.id.iv));
    }
}

设置adapter：

//--------------------------适配器--------------------------
            //Adapter适配器初始化
            recyclerView_forum.setLayoutManager(new LinearLayoutManager(getActivity()));
            //设置列表默认动画效果
            recyclerView_forum.setItemAnimator(new DefaultItemAnimator());
            //绑定适配器
            myBaseAdapter = new MyBaseAdapter(forum_list, getActivity());
            recyclerView_forum.setAdapter(myBaseAdapter);
            //列表点击事件
            myBaseAdapter.setOnItemClickLitener(new MyBaseAdapter.OnItemClickLitener() {
                @Override
                public void onItemClick(View view, int position) {
                    LogUtils.w("common帖子的点击事件：",
                            "点击的position:" + position);
                    Intent intent = new Intent(getActivity(), ForumArticleActivity.class);
                    intent.putExtra("帖子对象", forum_list.get(position));
                    ActivityUtils.startActivity(intent);
                }
            });
            //--------------------------适配器--------------------------
