推荐答案

您可以通过在Adapter类上添加以下代码来更改备用行的颜色. 您还可以使用此代码更改行的图像.

You can change the color of alternate row by adding the following code on your Adapter class. You can also change the images of your row by using this code.

将此代码放在适配器类的OnBindViewHolder中.

Put this code inside OnBindViewHolder in Adapter Class.

 if(position %2 == 1)
    {
        holder.itemView.setBackgroundColor(Color.parseColor("#FFFFFF"));
        //  holder.imageView.setBackgroundColor(Color.parseColor("#FFFFFF"));
    }
    else
    {
       holder.itemView.setBackgroundColor(Color.parseColor("#FFFAF8FD"));
       //  holder.imageView.setBackgroundColor(Color.parseColor("#FFFAF8FD"));
    }
