Android Json Bild recyclerView mit picasso Parsen

Question

Ich versuche, JSON-Daten zu analysieren, die Bild und Text eines Kontakts zu recyclerView hat, erhalte ich die Fehler

java.lang.NumberFormatException: Invalid int: "http://lorempixel.com/100/100/" 

Wenn ich versuche, das Bild zu setzen in onBindViewHolder() in meinem Adapter mit picasso

Das ist mein Adapter

package com.example.task; 

import android.content.Context; 
import android.support.v7.widget.RecyclerView; 
import android.text.Layout; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ImageView; 
import android.widget.TextView; 

import com.squareup.picasso.Picasso; 

import java.util.List; 

public class Adapter extends RecyclerView.Adapter<Adapter.MyViewHolder>{ 

    private List<Contact> contactList; 
    Context context ; 
    private LayoutInflater mInflater; 

    public Adapter(Context context ,List<Contact> contactList) { 
     this.context = context; 
     this.contactList = contactList; 
    } 

    @Override 
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View itemView = LayoutInflater.from(parent.getContext()) 
       .inflate(R.layout.recycler_card, parent, false); 

     return new MyViewHolder(itemView); 

    } 

    @Override 
    public void onBindViewHolder(MyViewHolder holder, int position) { 

     Contact item = contactList.get(position); 

     holder.title.setText(item.getName()); 

     Picasso.with(context).load(contactList.get(position).getProfilePic()) 
       .into((holder.profile_pic)); 

     //holder.profile_pic.setImageResource(Integer.parseInt(item.getProfilePic())); 
     //holder.year.setText(movie.getYear()); 

    } 

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

    public class MyViewHolder extends RecyclerView.ViewHolder { 

     TextView title; 
     ImageView profile_pic; 

     public MyViewHolder(View itemView) { 
      super(itemView); 
      title = (TextView) itemView.findViewById(R.id.name_left); 
      profile_pic = (ImageView) itemView.findViewById(R.id.profile_image_left); 


     } 
    } 
}

Dies wird der Link zum json api ich Zugriff auf

Was mache ich falsch?

Answer 1

Legen Sie den Rückgabetyp Ihrer "profile_pic" -Variable als Zeichenfolge fest und ändern Sie auch den Datentyp von "profile_pic" in String in Ihrer Contact.java-Klasse.
