RecycleView多布局的实现

在之前的一篇《RecycleView的简单使用，替代ListView、GridView并且实现瀑布流》http://www.jianshu.com/p/f6418086a1b3
介绍了RecycleView的简单使用，并实现了RecycleView的点击事件和长按事件，本篇文章主要讲解的是RecycleView实现多布局。
现在来看下效果图如下：

上图+实现了四种布局：现在来看看主布局XML：

<RelativeLayout 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" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:background="#E0F2F1"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context=".main.MainActivity">

<android.support.v7.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/recycleViewlist"
        />
</RelativeLayout>

其他四种布局：
布局一：item_01.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="200dp">
    <ImageView
        android:id="@+id/iv_item1"
        android:src="@mipmap/ic_launcher"
        android:layout_width="match_parent"
        android:layout_height="200dp" />
    <TextView
        android:id="@+id/tv_item1"
        android:text="title"
        android:textColor="#e5ffffff"
        android:textSize="20sp"
        android:textStyle="bold"
        android:layout_marginLeft="15dp"
        android:layout_marginTop="20dp"
        android:layout_marginRight="15dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</RelativeLayout>

布局二：item_list_recycle.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:background="@android:color/holo_orange_dark"
    android:layout_height="350dp">
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_margin="10dp"
        android:background="@android:color/white"
        android:layout_height="330dp">
        <ImageView
            android:id="@+id/img_shopping_img"
            android:src="@drawable/shop02"
            android:layout_width="match_parent"
            android:layout_margin="5dp"
            android:layout_height="150dp" />


        <LinearLayout
            android:id="@+id/line_shoppong"
            android:layout_width="match_parent"
            android:orientation="vertical"
            android:gravity="center"
            android:layout_below="@id/img_shopping_img"
            android:layout_height="wrap_content">
            <TextView
                android:id="@+id/tv_shopping_name"
                android:text="手机"
                android:padding="5dp"
                android:textSize="15sp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" />
            <TextView
                android:id="@+id/tv_shopping_desc"
                android:text="手机放寒假"
                android:padding="5dp"
                android:textSize="12sp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" />
            <TextView
                android:id="@+id/tv_shopping_new_money"
                android:text="￥5567"
                android:padding="5dp"
                android:textSize="14sp"
                android:textColor="@android:color/holo_red_light"
                android:layout_width="wrap_content"
                android:layout_marginRight="10dp"
                android:layout_height="wrap_content" />
            <View
                android:layout_width="0dp"
                android:layout_weight="1"
                android:layout_height="2dp"/>
            <Button
                android:id="@+id/item_shopping_order"
                android:layout_width="120dp"
                android:text="立即购买"
                android:layout_marginBottom="10dp"
                android:layout_marginRight="10dp"
                android:background="@android:color/holo_red_light"
                android:textColor="@android:color/white"
                android:layout_height="30dp" />

        </LinearLayout>
    </RelativeLayout>
</LinearLayout>

布局三和布局五一样：item_grid_recycle.xml

                android:textSize="12sp" />

        </LinearLayout>

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"

多布局实现的适配器：RecycleViewMulitAdapter
其中方法getItemViewType（position）获取数据源某个数据的类型；ViewHolder onCreateViewHolder(ViewGroup parent, int viewType)根据不同的viewtype创建不同的ViewHolder
onBindViewHolder(ViewHolder holder, int position)根据不同的viewtype把数据绑定到对应的布局中

public class RecycleViewMulitAdapter extends RecyclerView.Adapter<RecycleViewMulitAdapter.ViewHolder> implements View.OnClickListener
{

    Context mContext;
    List<RecycleListMode> listRecyDatas;
    LayoutInflater inflate;
    RecyclerView mRecycleView;
    private OnItemClickListener clickListener;
    public RecycleViewMulitAdapter(Context mContext, List<RecycleListMode> listRecyDatas) {

        this.mContext=mContext;
        this.listRecyDatas=listRecyDatas;
        inflate= LayoutInflater.from(mContext);
    }


    @Override

        mRecycleView=recyclerView;
    }

            notifyDataSetChanged();
        }

    }

    public void addLoadMore(List<RecycleListMode> dataload){

            notifyDataSetChanged();
        }

    }
