Introduction

RecyclerView是谷歌V7包下新增的控件,用来替代ListView的使用,在RecyclerView标准化了ViewHolder类似于ListView中convertView用来做视图缓存.先来说说RecyclerView的有点就是,他可以通过设置LayoutManager来快速实现listview、gridview、瀑布流的效果，而且还可以设置横向和纵向显示，添加动画效果也非常简单(自带了ItemAnimation，可以设置加载和移除时的动画，方便做出各种动态浏览的效果),也是官方推荐使用的.以下是官方的说明:

RecyclerView is a more advanced and flexible version of ListView. This widget is a container for large sets of views that can be recycled and scrolled very efficiently. Use the RecyclerView widget when you have lists with elements that change dynamically.简单说就是当你需要动态展示一组数据的时候就会需要用到它。

List

首先要用这个控件，你需要在gradle文件中添加包的引用(配合官方CardView使用)

compile 'com.android.support:cardview-v7:21.0.3'
compile 'com.android.support:recyclerview-v7:21.0.3'

然后是在XML文件用使用它

<android.support.v7.widget.RecyclerView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/recycler_view"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"/>

接着在Activity中设置它

public class MainActivity extends ActionBarActivity {
  @InjectView(R.id.recycler_view)
  RecyclerView mRecyclerView;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ButterKnife.inject(this);

    mRecyclerView.setLayoutManager(new LinearLayoutManager(this)); //这里用线性显示 类似于listview

    //        mRecyclerView.setLayoutManager(new GridLayoutManager(this, 2));//这里用线性宫格显示 类似于grid view
    //        mRecyclerView.setLayoutManager(new StaggeredGridLayoutManager(2, OrientationHelper.VERTICAL));//这里用线性宫格显示 类似于瀑布流
    mRecyclerView.setAdapter(new NormalRecyclerViewAdapter(this));
  }

  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
  }

  @Override
  public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    if (id == R.id.action_settings) {
      return true;
    }

    return super.onOptionsItemSelected(item);
  }
}

然后是适配器代码

public class NormalRecyclerViewAdapter extends RecyclerView.Adapter<NormalRecyclerViewAdapter.NormalTextViewHolder> {
    private final LayoutInflater mLayoutInflater;
    private final Context mContext;
    private String[] mTitles;

    public NormalRecyclerViewAdapter(Context context) {
        mTitles = context.getResources().getStringArray(R.array.titles);
        mContext = context;
        mLayoutInflater = LayoutInflater.from(context);
    }

    @Override
    public NormalTextViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return new NormalTextViewHolder(mLayoutInflater.inflate(R.layout.item_text, parent, false));
    }

    @Override
    public void onBindViewHolder(NormalTextViewHolder holder, int position) {
        holder.mTextView.setText(mTitles[position]);
    }

    @Override
    public int getItemCount() {
        return mTitles == null ? 0 : mTitles.length;
    }

    public static class NormalTextViewHolder extends RecyclerView.ViewHolder {
        @InjectView(R.id.text_view)
        TextView mTextView;

        NormalTextViewHolder(View view) {
            super(view);
            ButterKnife.inject(this, view);
            view.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Log.d("NormalTextViewHolder", "onClick--> position = " + getPosition());
                }
            });
        }
    }
}
