recyclerview需要导入support-v7使用
recyclerview优点是切换样式容易一个可以顶ListView GridView使用
recyclerview缺点是没有点击长按事件需要自己写
插拔式的体验，高度的解耦，异常的灵活

导入

    compile 'com.android.support:recyclerview-v7:25.+'

MainActivity

    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initData();        recyclerView = (RecyclerView) findViewById(R.id.id_recyclerview);        /**         * 这里是控制RecyclerView的样式         *  LinearLayoutManager 就类似listview 上到下的排列         *  GridLayoutManager 就是Gridview  4是列数         *  StaggeredGridLayoutManager  也像Gridview  可以控制上到下的排列 也可以左到右的排列         *///        recyclerView.setLayoutManager(new LinearLayoutManager(this));//        recyclerView.setLayoutManager(new GridLayoutManager(this, 4));//        recyclerView.setLayoutManager(new StaggeredGridLayoutManager(4,StaggeredGridLayoutManager.VERTICAL));        recyclerView.setLayoutManager(new StaggeredGridLayoutManager(3, StaggeredGridLayoutManager.HORIZONTAL));//        recyclerView.setAdapter(animationListAdapter = new AnimationListAdapter(this, strings));        recyclerView.setAdapter(mAdapter = new RecyclerAdapter(this, strings));        recyclerView.setItemAnimator(new DefaultItemAnimator());        SpacesItemDecoration decoration = new SpacesItemDecoration(16);        recyclerView.addItemDecoration(decoration);    }    protected void initData() {        strings = new ArrayList<String>();        for (int i = 'a'; i <= 'z'; i++) {            strings.add("" + (char) i);        }    }

Adapter

class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.Holder> {    private static final String TAG = "RecyclerAdapter";    private Context context;    private List<String> strings;    public RecyclerAdapter(Context context, List<String> strings) {        this.context = context;        this.strings = strings;    }    @Override    public Holder onCreateViewHolder(ViewGroup parent, int viewType) {        Holder holder = new Holder(LayoutInflater.from(context).inflate(R.layout.item, parent,                false));        return holder;    }    @Override    public void onBindViewHolder(Holder holder, int position) {        holder.textView.setText(strings.get(position));    }    @Override    public int getItemCount() {        return strings.size();    }    class Holder extends RecyclerView.ViewHolder {        TextView textView;        public Holder(View view) {            super(view);            textView = (TextView) view.findViewById(R.id.textView);        }    }    }

mainactivity layout

<?xml version="1.0" encoding="utf-8"?><android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.team.we.recyclerview.MainActivity">    <android.support.v7.widget.RecyclerView        android:id="@+id/id_recyclerview"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:divider="#ffff0000"        android:dividerHeight="10dp" /></android.support.constraint.ConstraintLayout>

itemlayout

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:background="@color/colorPrimary"    android:layout_height="150dp">    <TextView        android:id="@+id/textView"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_centerHorizontal="true"        android:layout_centerVertical="true"        android:gravity="center_horizontal|center_vertical" /></RelativeLayout>

持续更新中，下次更新点击事件和item刷新增删 item交换操作
