RecyclerView多条目加载（网络请求数据）

RecyclerView多条目加载和ListView的多条目加载用法是一样的，代码如下：

1.导入RecyclerView或XRecyclerView的依赖包（自己按照需求导入依赖包，下面RecyclerView可以替换成XRecyclerView）XRecyclerView可以实现上拉加载，下拉刷新，而RecyclerView不可以

//Recyclerview
compile 'com.android.support:recyclerview-v7:22.1.1'
compile 'com.android.support:appcompat-v7:22.1.1'

2.xml的布局文件

<android.support.v7.widget.RecyclerView
android:id="@+id/id_recyclerview"
android:divider="#ffff0000"
android:dividerHeight="10dp"
android:layout_width="match_parent"
android:layout_height="match_parent" />

3.自己定义多条目的布局

一、Adapter(简单的多条目)

public class ThreeAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

private final int TYPRONE = 1;
private final int TYPETWO = 2;

Context context;
MusicBean bean;

ArrayList<MusicBean.SongListBean> list;
ArrayList<MusicBean.SongListBean> list1;

public ThreeAdapter(Context context, MusicBean bean) {
this.context = context;
this.bean = bean;
}

@Override
public int getItemViewType(int position) {
if(position%2==0){
return TYPRONE;
} else if(position%2==1){
return TYPETWO;
} else {
return super.getItemViewType(position);
}
}

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if(viewType==TYPRONE){
View view = LayoutInflater.from(context).inflate(R.layout.three_item_one, null);
ViewHolderA viewHolderA = new ViewHolderA(view);
return viewHolderA;
}else if(viewType==TYPETWO){
View view = LayoutInflater.from(context).inflate(R.layout.three_item_two, null);
ViewHolderB viewHolderB = new ViewHolderB(view);
return viewHolderB;
}

return null;
}

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
if(holder instanceof ViewHolderA){
list1=new ArrayList<>();
for(int i=0;i<bean.getSong_list().size();i++){
list1.add(new MusicBean.SongListBean(bean.getSong_list().get(position).getPic_small(),bean.getSong_list().get(position).getTitle()));
}
ImageLoader.getInstance().displayImage(list1.get(position).getPic_small(),((ViewHolderA) holder).img);
}else if(holder instanceof ViewHolderB){
list=new ArrayList<>();
for(int i=0;i<bean.getSong_list().size();i++){
list.add(new MusicBean.SongListBean(bean.getSong_list().get(position).getPic_small(),bean.getSong_list().get(position).getTitle()));
}
((ViewHolderB) holder).text.setText(list.get(position).getTitle());
}
}

@Override
public int getItemCount() {
return bean.getSong_list().size();
}

class ViewHolderA extends RecyclerView.ViewHolder{

ImageView img;

public ViewHolderA(View itemView) {
super(itemView);
img= (ImageView) itemView.findViewById(R.id.item_img);
}
}

class ViewHolderB extends RecyclerView.ViewHolder{

TextView text;

public ViewHolderB(View itemView) {
super(itemView);
text= (TextView) itemView.findViewById(R.id.item_text);
}
}

MainActivity（简单的）

RecyclerView re_three;
ArrayList<MusicBean.SongListBean> songs;
private String position;
ThreeAdapter adapter;
String url;
String url2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_three);

re_three= (RecyclerView) findViewById(R.id.re_three);
url="http://tingapi.ting.baidu.com/v1/restserver/ting?method=baidu.ting.billboard.billList&type=1&size=1

&offset=0";

position = getIntent().getStringExtra("position"); getData();}public void getData() { OkHttp3Utils.getInstance().doGet(url, new GsonObjectCallback<MusicBean>() { @Override public void onUi(MusicBean musicBean) { musicBean.getSong_list(); //Log.d("main2",musicBean.getSong_list().get(0).getAlbum_title()+"---"); adapter=new ThreeAdapter(ThreeActivity.this,musicBean); re_three.setLayoutManager(new LinearLayoutManager(ThreeActivity.this)); re_three.setAdapter(adapter); adapter.notifyDataSetChanged(); } @Override public void onFailed(Call call, IOException e) { } });}

二、Adapter(复杂的)

Home_goods.DataBean list;
Context mcontext;
ArrayList mlist;
ArrayList mlist2;
ArrayList imgs_gwc;
ArrayList<Home_goods.DataBean.SubjectsBean.GoodsListBeanX> goodslist;
private Intent intent;

//枚举类型
private enum Item_Type{
Typeone ,Typetwo,Typethree,Typefour,Typefive,Typesix;
}

public XRAdapter(Context mcontext, Home_goods.DataBean list) {
this.mcontext = mcontext;
this.list = list;
intent = new Intent(mcontext, HomeWebActivity.class);

}

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if (viewType == Item_Type.Typeone.ordinal()) {
View mView = LayoutInflater.from(mcontext).inflate(R.layout.recycler_item_one, null);
ViewHolderA viewHolder = new ViewHolderA(mView);
return viewHolder;

} else if (viewType == Item_Type.Typetwo.ordinal()) {

View mView = LayoutInflater.from(mcontext).inflate(R.layout.recycler_item_two, null);
ViewHolderB viewHolder = new ViewHolderB(mView);
return viewHolder;
} else if (viewType == Item_Type.Typethree.ordinal()) {
View mView = LayoutInflater.from(mcontext).inflate(R.layout.recycler_item_three, null);
ViewHolderC viewHolder = new ViewHolderC(mView);
return viewHolder;
}else if (viewType == Item_Type.Typefour.ordinal()) {
View mView = LayoutInflater.from(mcontext).inflate(R.layout.recycler_item_four, null);
ViewHolderD viewHolder = new ViewHolderD(mView);
return viewHolder;
}else if (viewType == Item_Type.Typefive.ordinal()) {
View mView = LayoutInflater.from(mcontext).inflate(R.layout.recycler_item_five, null);
ViewHolderE viewHolder = new ViewHolderE(mView);
return viewHolder;
}else if (viewType == Item_Type.Typesix.ordinal()) {
View mView = LayoutInflater.from(mcontext).inflate(R.layout.recycler_item_six, null);
ViewHolderF viewHolder = new ViewHolderF(mView);
return viewHolder;
}

return null;
}

@Override
public void onBindViewHolder(final RecyclerView.ViewHolder holder, int position) {
if (holder instanceof ViewHolderA) {
mlist=new ArrayList();
for(int i=0;i<list.getAd1().size();i++){
mlist.add(list.getAd1().get(i).getImage());
}
//设置图片加载器
((ViewHolderA) holder).mbanner.setImageLoader(new GlideImageLoader());

}
});

} else if (holder instanceof ViewHolderB) {

((ViewHolderB) holder).t4.setText(list.getAd5().get(3).getTitle());

ImageLoader.getInstance().displayImage(list.getAd5().get(0).getImage(),((ViewHolderB) holder).img1);

((ViewHolderE) holder).banner2.setImages(mlist2);

@Override
