CustomPicasso.java

import android.content.Context; 
import android.util.Log; 

import com.jakewharton.picasso.OkHttp3Downloader; 
import com.squareup.picasso.Picasso; 

/**

public class CustomPicasso { 

    private static String LOG_TAG = CustomPicasso.class.getSimpleName(); 
    private static boolean hasCustomPicassoSingletonInstanceSet; 

    public static Picasso with(Context context) { 

     if (hasCustomPicassoSingletonInstanceSet) 
      return Picasso.with(context); 

     try { 
      Picasso.setSingletonInstance(null); 
     } catch (IllegalStateException e) { 
      Log.w(LOG_TAG, "-> Default singleton instance already present" + 
        " so CustomPicasso singleton cannot be set. Use CustomPicasso.getNewInstance() now."); 
      return Picasso.with(context); 
     } 

     Picasso picasso = new Picasso.Builder(context). 
       downloader(new OkHttp3Downloader(context)) 
       .build(); 

     Picasso.setSingletonInstance(picasso); 
     Log.w(LOG_TAG, "-> CustomPicasso singleton set to Picasso singleton." + 
       " In case if you need Picasso singleton in future then use Picasso.Builder()"); 
     hasCustomPicassoSingletonInstanceSet = true; 

     return picasso; 
    } 

    public static Picasso getNewInstance(Context context) { 

     Log.w(LOG_TAG, "-> Do not forget to call customPicasso.shutdown()" + 
       " to avoid memory leak"); 

     return new Picasso.Builder(context). 
       downloader(new OkHttp3Downloader(context)) 
       .build(); 
    } 
} 

build.gradle (모듈 : 응용 프로그램)

android { 

    ... 

} 

dependencies { 

    ... 

    compile 'com.squareup.picasso:picasso:2.5.2' 
    compile 'com.jakewharton.picasso:picasso2-okhttp3-downloader:1.1.0' 
} 

사용 -

CustomPicasso.with(context) 
    .load("http://api.learn2crack.com/android/images/donut.png") 
    .resize(218, 192) 
    .centerCrop() 
    .into(holder.coverImageViewa); 

Answer 2

URL 문제입니다. http에서 https로 리디렉션하는 URL을 사용하므로 Picasa가 이미지를로드하지 않습니다. URL에 http 대신 https를 사용하면 작동합니다.
