xrecyclerview多条目布局
1.导入依赖包
` compile 'com.jcodecraeer:xrecyclerview:1.3.2'2.布局文件
<com.jcodecraeer.xrecyclerview.XRecyclerView
android:id="@+id/home_xrcv"
android:layout_below="@id/seach_top"
android:layout_width="match_parent"
android:layout_height="match_parent">
com.jcodecraeer.xrecyclerview.XRecyclerView>4.加载布局管理器
//加布局管理器
LinearLayoutManager layoutManager=new LinearLayoutManager(getActivity());
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
homeXrcv.setLayoutManager(layoutManager);5.设置 上拉加载下拉刷新的功能,
//设置上拉和下拉监听
homeXrcv.setLoadingListener(new XRecyclerView.LoadingListener() {
@Override
public void onRefresh() {
//refresh data here
//刷新时清空
curr=0;
list.clear();
getData(API.TYPE_HOME,curr);
//刷新控件
homeXrcv.refreshComplete();
}
@Override
public void onLoadMore() {
// load more data here
//分页加载时使用
/* curr++;
getData(API.TYPE_HOME,curr);
xr.refreshComplete();*/
}
});
//加载数据
getData(API.TYPE_HOME,curr);6.最关键的一步来了添加适配器
package sizu.nanshigou.adapter;
import android.content.Context;
import android.support.v7.widget.DefaultItemAnimator;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.StaggeredGridLayoutManager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import com.nostra13.universalimageloader.core.ImageLoader;

import sizu.nanshigou.view.GlideImageLoader;
import sizu.nanshigou.view.SpacesItemDecoration;
public class XRAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
HomeBean.DataBean data;
Context mcontext;
ArrayList mlist;
ArrayList bannerlist;
//枚举类型
private enum Item_Type {
Typeone, Typetwo, Typethree, Typefour, Typefive
}
//构造方法
public XRAdapter(HomeBean.DataBean data, Context mcontext) {
this.data = data;
this.mcontext = mcontext;
}
/**
* 创建ViewHolder
*
* @param parent
* @param viewType :不同ItemView的类型加载布局
* @return
*/
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if (viewType == Item_Type.Typeone.ordinal()) {
View mView = LayoutInflater.from(mcontext).inflate(R.layout.recycle_item_a, null);
ViewHolderA viewHolder = new ViewHolderA(mView);
return viewHolder;
} else if (viewType == Item_Type.Typetwo.ordinal()) {

}
return null;
}
/**
* 绑定数据：可以直接拿到已经绑定控件的Viewholder对象
*
* @param holder
* @param position
*/
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
//判断条目类型
if (holder instanceof ViewHolderA) {
mlist = new ArrayList();
for (int i = 0; i < data.getAd1().size(); i++) {
mlist.add(data.getAd1().get(i).getImage());
}
//设置banner图片加载器
((ViewHolderA) holder).mbanner.setImageLoader(new GlideImageLoader());
((ViewHolderA) holder).mbanner.setImages(mlist);
((ViewHolderA) holder).mbanner.start();
} else if (holder instanceof ViewHolderB) {
//给子布局的控件传值
ImageLoader.getInstance().displayImage(data.getAd5().get(0).getImage(), ((ViewHolderB) holder).homeClassifiledImg1);
((ViewHolderB) holder).homeClassifiledText1.setText(data.getAd5().get(0).getTitle());
} else if (holder instanceof ViewHolderC) {

((ViewHolderC) holder).tvc.setText("热门活动");
ImageLoader.getInstance().displayImage(data.getActivityInfo().getActivityInfoList().get(0).getActivityImg(), ((ViewHolderC) holder).tvcHotImg1);
ImageLoader.getInstance().displayImage(data.getActivityInfo().getActivityInfoList().get(1).getActivityImg(), ((ViewHolderC) holder).tvcHotImg2);
} else if (holder instanceof ViewHolderD) {
bannerlist = new ArrayList<>();
for (int i = 0; i < data.getSubjects().size(); i++) {
bannerlist.add(data.getSubjects().get(i).getImage());
}
((ViewHolderD) holder).reItemdText.setText("热门专题");
((ViewHolderD) holder).itemdMybanner.setImageLoader(new GlideImageLoader());
((ViewHolderD) holder).itemdMybanner.setImages(bannerlist);
((ViewHolderD) holder).itemdMybanner.start();
} else if (holder instanceof ViewHolderE) {
//设置layoutManager
((ViewHolderE) holder).recyclerView.setLayoutManager(new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL));
// 设置item动画
((ViewHolderE) holder).recyclerView.setItemAnimator(new DefaultItemAnimator());
//设置item之间的间隔
SpacesItemDecoration decoration=new SpacesItemDecoration(16);
((ViewHolderE) holder).recyclerView.addItemDecoration(decoration);
List defaultGoodsList = data.getDefaultGoodsList();
((ViewHolderE) holder).recyclerView.setAdapter( new MasonryAdapter(mcontext,defaultGoodsList));
}
}
//得到item的数量
@Override
public int getItemCount() {
return 5;
}
//得到viewType类型 返回值赋值给onCreateViewHolder的参数
@Override
public int getItemViewType(int position) {
// return super.getItemViewType(position);
//根据下标判断类型返回布局
if (position == 0) {
return Item_Type.Typeone.ordinal();
} else if (position == 1) {
return Item_Type.Typetwo.ordinal();
} else if (position == 2) {
return Item_Type.Typethree.ordinal();
} else if (position == 3) {
return Item_Type.Typefour.ordinal();
} else if (position == 4) {
return Item_Type.Typefive.ordinal();
}
return -1;
}
class ViewHolderA extends RecyclerView.ViewHolder {
public Banner mbanner;
public ViewHolderA(View itemView) {
super(itemView);
mbanner = (Banner) itemView.findViewById(R.id.mybanner);
}
}
class ViewHolderB extends RecyclerView.ViewHolder {
//得到控件
@BindView(R.id.home_classifiled_img1)
ImageView homeClassifiledImg1;
@BindView(R.id.home_classifiled_text1)
TextView homeClassifiledText1;
public ViewHolderB(View itemView) {
super(itemView);
//初始化ButterKnife
ButterKnife.bind(this, itemView);
}
}
class ViewHolderC extends RecyclerView.ViewHolder {
@BindView(R.id.tvc)
TextView tvc;
@BindView(R.id.countdownView)
CountdownView countdownView;
@BindView(R.id.tvc_hot_img1)
ImageView tvcHotImg1;
@BindView(R.id.tvc_hot_img2)
ImageView tvcHotImg2;
public ViewHolderC(View itemView) {
super(itemView);
ButterKnife.bind(this, itemView);
}
}
class ViewHolderD extends RecyclerView.ViewHolder {
@BindView(R.id.itemd_mybanner)
Banner itemdMybanner;
@BindView(R.id.re_itemd_text)
TextView reItemdText;
public ViewHolderD(View itemView) {
super(itemView);
ButterKnife.bind(this, itemView);
}
}
class ViewHolderE extends RecyclerView.ViewHolder {
@BindView(R.id.id_recyclerview)
RecyclerView recyclerView;
public ViewHolderE(View itemView) {
super(itemView);
ButterKnife.bind(this, itemView);
}
}
} 7.最后一步网络请求数据里添加适配器
点击 Okhttp网络请求封装使用
private void getData(String url,int curr) { OkHttp3Utils.getInstance().doGet(url, new GsonObjectCallback() {
@Override
public void onUi(HomeBean homeBean) {
homeBean.getMsg();
//添加适配器
XRAdapter mxradapter=new XRAdapter(homeBean.getData(),getActivity());
homeXrcv.setAdapter(mxradapter);
}
@Override
public void onFailed(Call call, IOException e) {
}
});
}
