RecyclerView的高级使用

1、ScrollView嵌入RecyclerView的处理
用NestedScrollView替代ScrollView，如下布局：

<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:fresco="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/bgWhite"
android:fillViewport="true">
<LinearLayout
android:id="@+id/rl_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
...
<android.support.v7.widget.RecyclerView
android:id="@+id/rv_ofen_buy"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView

注意android:fillViewport这个属性，运行NestedScrollView里面的组件填充它。
2、RecyclerView的多布局

3、RecyclerView的刷新
相比ListView的刷新notifyDataSetChanged()，RecyclerView额外增加了如下的一些刷新方法：

notifyItemChanged(int position)

notifyItemChanged(int position, Object payload)

notifyItemRangeChanged(int positionStart, int itemCount)

notifyItemRangeChanged(int positionStart, int itemCount, Object payload)

notifyItemRemoved(int position)

notifyItemRangeRemoved(int positionStart, int itemCount)

notifyItemInserted(int position)

notifyItemRangeInserted(int positionStart, int itemCount)

notifyItemMoved(int fromPosition, int toPosition)
