und-Code in Adapter, hat Adapter den Kontext der Aktivität, was wiederum zu FrescoImageViewer geführt wird:

holder.simpleDraweeView.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      Log.d(TAG, holder.getAdapterPosition()+" "); 
      new ImageViewer.Builder<>(context,fileMaps) 
        .setFormatter(new ImageViewer.Formatter<FileMap>(){ 
         @Override 
         public String format(FileMap fileMap) { 
          return fileMap.getUrls().get(0).getUrl(); 
         } 
        }) 
        .show(); 
     } 
    });

Answer 1

Sie müssen die AppCompatActivity Themen Rahmen der Tätigkeit gesetzt verwenden, die es Ihre Anwendung scheint nicht

Ersetzen Sie alle getApplicationContext() mit QueryImageGalleryActivity.this (die aktuelle Aktivität/Kontext)
