Descrifit + Fresco requests network data and displays it to RecyclerView,

Pull fit + Fresco requests network data and displays it to RecyclerView. First look at the effect, the effect is a bit ugly, but focus on Functions

Step 1: import dependencies

compile 'com.android.support:recyclerview-v7:26.1.0'    compile 'com.facebook.fresco:fresco:0.9.0+'    compile 'com.squareup.retrofit2:retrofit:2.0.0-beta4'    compile 'com.squareup.retrofit2:converter-gson:2.0.0-beta3'

Step 2: Add network Permissions

Below is the code

Display Layout

activity_main

list_item

Api

public class Api { public final static String A="https://120.27.23.105/"; public final static String B = "ad/getAd"; } 

Service Interface

public interface Service { @GET(Api.B) Call
 
   getDatas(); } 
 

The MyApp class is used for Fresco initialization.

import com.facebook.drawee.backends.pipeline.Fresco; /** * Created by BAIPEI on 2018/1/1. */ public class MyApp extends Application { @Override public void onCreate() { super.onCreate(); Fresco.initialize(this); } }

Apadper adapter class

import android.content.Context; import android.net.Uri; import android.support.v7.widget.RecyclerView; import android.view.View; import android.view.ViewGroup; import android.widget.TextView; import com.facebook.drawee.view.SimpleDraweeView; /** * Created by BAIPEI on 2018/1/1. */ public class Apadper extends RecyclerView.Adapter { Context context; Datas datas; public Apadper(Context context, Datas datas) { this.context = context; this.datas = datas; } @Override public Apadper.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view=View.inflate(context,R.layout.list_item,null); return new MyViewHolder(view); } @Override public void onBindViewHolder(Apadper.MyViewHolder holder, int position) { holder.tv1.setText(datas.getData().get(position).getTitle()); holder.tv2.setText(datas.getData().get(position).getType()+""); holder.sv.setImageURI(Uri.parse(datas.getData().get(position).getIcon())); } @Override public int getItemCount() { return datas.getData().size(); } public class MyViewHolder extends RecyclerView.ViewHolder{ SimpleDraweeView sv; TextView tv1,tv2; public MyViewHolder(View itemView) { super(itemView); tv1=itemView.findViewById(R.id.tv1); tv2=itemView.findViewById(R.id.tv2); sv=itemView.findViewById(R.id.sv); } } }
