CarouselLayoutManager的使用

先上图：

使用时使用 RecyclerView，除了 LayoutManager 使用 CarouselLayoutManager外，其余用法全和 RecyclerView 一样。

下面介绍具体的使用方法：

（1）添加依赖：

 compile 'com.azoft.carousellayoutmanager:carousel:1.2.1'

（2）主要逻辑代码：

//垂直显示还是水平显示

CarouselLayoutManager layoutManager = new
        CarouselLayoutManager(CarouselLayoutManager.VERTICAL);

recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
adapter.setUrl(urls);
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setHasFixedSize(true);

//这两个必须设置
layoutManager.setPostLayoutListener(new CarouselZoomPostLayoutListener());
recyclerView.addOnScrollListener(new CenterScrollListener());

（3）全部代码：

1）适配器：

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {    private Context context;    private List<String> urls;    public MyAdapter(Context context) {        this.context = context;    }    public void setUrl(List<String> url) {        this.urls = url;        notifyDataSetChanged();    }    @Override    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        View view = LayoutInflater.from(context).inflate(R.layout.item,parent,false);        MyViewHolder holder = new MyViewHolder(view);        return holder;    }    @Override    public void onBindViewHolder(MyViewHolder holder, final int position) {        Glide.with(context).load(urls.get(position)).into(holder.imageView);        holder.imageView.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                Toast.makeText(context, "position:" + position, Toast.LENGTH_SHORT).show();            }        });    }    @Override    public int getItemCount() {        return urls.size();    }    class MyViewHolder extends RecyclerView.ViewHolder{        private ImageView imageView;        public MyViewHolder(View itemView) {            super(itemView);            imageView = (ImageView) itemView.findViewById(R.id.iv);        }    }}

2）MainActivity:

public class MainActivity extends AppCompatActivity {    private RecyclerView recyclerView;    private List<String> urls;    private MyAdapter adapter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        adapter = new MyAdapter(this);        urls = new ArrayList<>();        for (int i = 0; i < 8; i++) {            urls.add("http://cdn.indata3.com/images/20170630062508d2ib32lBty95o5RS/20170818/1503034118_10.jpeg");        }        CarouselLayoutManager layoutManager = new                CarouselLayoutManager(CarouselLayoutManager.VERTICAL);        recyclerView = (RecyclerView) findViewById(R.id.recycler_view);        adapter.setUrl(urls);        recyclerView.setAdapter(adapter);        recyclerView.setLayoutManager(layoutManager);        recyclerView.setHasFixedSize(true);        layoutManager.setPostLayoutListener(new CarouselZoomPostLayoutListener());        recyclerView.addOnScrollListener(new CenterScrollListener());    }}

3)activity_main.xml：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="sosee.demoglarypic.MainActivity">    <android.support.v7.widget.RecyclerView        android:id="@+id/recycler_view"        android:layout_width="match_parent"        android:layout_height="match_parent"/></LinearLayout>

4）item.xml:

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="wrap_content"    android:layout_height="wrap_content">    <ImageView        android:layout_centerInParent="true"        android:id="@+id/iv"        android:layout_width="200dp"        android:layout_height="260dp" /></RelativeLayout>
