我想使用Picasso将Color设置为占位符图像.

我试过这个:

    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);

但它会导致以下错误:
