RecyclerView

工程源码
添加对应的支持库

compile 'com.android.support:recyclerview-v7:24.2.1'
compile 'com.android.support:cardview-v7:24.2.1'

添加 res/layout/recycler_view.xml

在ListContentFragment.java TileContentFragment.java 和 CardContentFragment.java中
分别创建各自的ContentAdapter,在onCreateView方法中初始化RecyclerView相关的内容

@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    RecyclerView recyclerView = (RecyclerView)inflater.inflate(R.layout.recycler_view,container,false);
    ContentAdapter adapter = new ContentAdapter(recyclerView.getContext());
    recyclerView.setAdapter(adapter);
    recyclerView.setHasFixedSize(true);
    recyclerView.setLayoutManager(new GridLayoutManager(getActivity(),2));
    return recyclerView;
}

public static class ViewHolder extends RecyclerView.ViewHolder{
  public ImageView imageView;
  public TextView textView;
  public ViewHolder(LayoutInflater inflater,ViewGroup parent) {
      super(inflater.inflate(R.layout.item_tile,parent,false));
      imageView = (ImageView)itemView.findViewById(R.id.title_picture);
      textView = (TextView)itemView.findViewById(R.id.title_title);
  }
}

public static class ContentAdapter extends RecyclerView.Adapter{
  private static final int LENGTH = 18;
  private String[] names;
  private Drawable[] avatars;

  public ContentAdapter(Context context) {
      Resources resources = context.getResources();
      names = resources.getStringArray(R.array.places);
      TypedArray a = resources.obtainTypedArray(R.array.places_picture);
      avatars = new Drawable[a.length()];
      for(int i = 0;i
