//先贴一下Bean类需要重写MultiItemEntity，这个重写之后会有一个方法，我这里写了一个Index Integer类型的。然后配置一下get和set方法。记得return 返回Index

下边是适配器
//我的布局比较简单两个布局一个里边是一个按钮一个里边是一个texView
public class Adapterextends BaseMultiItemQuickAdapter {
public Adapter(@Nullable List data) {
super(data);
//添加自己的多布局
addItemType(0,R.layout.day8_recitem);
addItemType(1,R.layout.day8_recitemmain);
}
@Override
protected void convert(@NotNull BaseViewHolder baseViewHolder, FoodsBean.DataBean dataBean) {
这里的dataBean的getIndex就是刚刚Bean类自己设置的Integer类型。
switch (dataBean.getIndex()){
case 1:
//数据源绑定控件和正常的ViewHolder一样
baseViewHolder.setText(R.id.day8_text,dataBean.getFood_str());
break;
case 0:
baseViewHolder.setText(R.id.day8_btn,dataBean.getTitle());
break;
}
}
}
MainAct 这里解析数据用的是OKGO的get请求
public class Day8Activityextends AppCompatActivity {
private RecyclerViewday8Rec;
private ListmyData=new ArrayList<>();
private Adapteradapter;
int a=1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_day8);
initView();
day8Rec.setLayoutManager(new LinearLayoutManager(this));
//Get
OkGo.get("http://www.qubaobei.com/ios/cf/dish_list.php?stage_id=1&limit=20&page=1").execute(new StringCallback() {
@Override
public void onSuccess(Response response) {
String string = response.body();
Gson gson=new Gson();
//解析数据
FoodsBean foodsBean = gson.fromJson(string, FoodsBean.class);
myData=foodsBean.getData();
adapter =new Adapter(myData);
day8Rec.setAdapter(adapter);
//这里比较重要我这里设置的a=1；这里和adapter的绑定控件添加数据源有关，同时还设置了要选中的布局是哪一个
for (int i =0; i
myData.get(i).setIndex(a%2);
a++;
}
adapter =new Adapter(myData);
day8Rec.setAdapter(adapter);
}
});
}
private void initView() {
day8Rec = (RecyclerView) findViewById(R.id.day8_rec);
}
}
