Pay'ı Picasso ile yer tutucu görüntüsü olarak nasıl kullanabilirim?

Question

Renk olarak yer tutucu görüntüsü ayarlamak için Picasso'yu kullanmak istiyorum.

bu çalıştı:

int placeHolderColor2 = Color.rgb(20,20,20); 

    Picasso.with(context) 
     .load(item.getImageUrls().get(0)) 
     .placeholder(placeHolderColor2) 
     .error(R.drawable.card_image) 
     .centerCrop() 
     .fit() 
     .into(viewHolder.imageView); 

Ama şu hataya yol açmaktadır:

nasıl Picasso ile yer tutucu görüntüsü olarak bir Renk kullanabilir?

Answer 1

Sen hatadan anlayabileceği kendisini Picasso

ait android.content.res.Resources$NotFoundException: Resource ID #0xff141414

kullanılabilmesi için son sürümünü log Ve ben bir renk yer tutucu yapmak için bu çözümü kullanılan Projemde bu

Picasso.with(mContext).load("URL").placeholder(R.color.holder_color).error(R.color.error_color).into(viewHolder.imageView); 

Answer 2

deneyin

 gradientDrawable = new GradientDrawable(); 
     gradientDrawable.setShape(GradientDrawable.RECTANGLE); 
     gradientDrawable.setColor(color); 

Picasso.with(context) 
    .load(item.getImageUrls().get(0)) 
    .placeholder(gradientDrawable) 
    .error(R.drawable.card_image) 
    .centerCrop() 
    .fit() 
    .into(viewHolder.imageView); 

Bu yaklaşım, ImageView öğesinin wrap_content olarak ayarlanmasına yardımcı olur, çünkü basit bir renk dolumu resim yükleninceye kadar görüntünüzü görünmez yapar, çünkü bildiğiniz gibi, renk herhangi bir yer kaplamaz.
