Modle层：

Contract层：
public class Contract {    //    1、创建View  get/set    public interface IDataView {        void setData(List<Bean.DataBean> list);//   void setText(String str);//    String getText();    }    //    2、Model接口    public interface IDataModel {        //获取数据        void getData(DataModel.IGetDataFromNet iGetDataFromNet);//此处需要回调接口    }    //    3、Presenter接口    public interface IDataPresenter {        void showData();    }}

Presenter层：public class DataPresenter implements Contract.IDataPresenter{    //需要Model,view    private DataModel model;    private Contract.IDataView view;    public DataPresenter(Contract.IDataView view) {        this.view = view;        model = new DataModel();    }    @Override    public void showData() {        model.getData(new DataModel.IGetDataFromNet() {            @Override            public void getData(List<Bean.DataBean> list) {                view.setData(list);            }        });    }}

适配器：
public class Adapter extends RecyclerView.Adapter<Adapter.ViewHolder>{    private List<Bean.DataBean> list = new ArrayList<>();    private Context context;    private LayoutInflater inflater;    public Adapter(List<Bean.DataBean> list, Context context) {        this.list = list;        this.context = context;        inflater = LayoutInflater.from(context);    }    @Override    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        View view = inflater.inflate(R.layout.item, parent, false);        return new ViewHolder(view);    }    @Override    public void onBindViewHolder(ViewHolder holder, int position) {        Bean.DataBean bean = list.get(position);        holder.tv.setText(bean.title);        Glide.with(context).load(bean.img.get(0).url).into(holder.iv);    }    @Override    public int getItemCount() {        return list==null?0:list.size();    }    public class ViewHolder extends RecyclerView.ViewHolder {        public ImageView iv;        public TextView tv;        public ViewHolder(View itemView) {            super(itemView);            iv = itemView.findViewById(R.id.img);            tv = itemView.findViewById(R.id.tv);        }    }}
Main_Activity类： public class Main_Activity extends AppCompatActivity implements Contract.IDataView{    private RecyclerView my_recycler;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_second);               initView();    }    private void initView() {        my_recycler = (RecyclerView) findViewById(R.id.recyclerview);        LinearLayoutManager manager = new LinearLayoutManager(this);        my_recycler.setLayoutManager(manager);        DataPresenter presenter = new DataPresenter(this);        presenter.showData();    }    @Override    public void setData(List<Bean.DataBean> list) {        Adapter adapter = new Adapter(list,this);        my_recycler.setAdapter(adapter);    }}
