        if(fb == 0 && tw == 0) {

       mImageViewCapUser = (ImageView) itemLayoutView.findViewById(R.id.imgv_capture_user); 
       mImageViewIcon = (ImageView) itemLayoutView.findViewById(R.id.imgv_Icon_list); 
       mImageViewPriority = itemLayoutView.findViewById(R.id.imgv_priority); 
      } 
     } 


     @Override 
     public int getItemCount() { 

      return dashboardPhotoses.length; 
     } 
} 

请帮助我，如果任何人有这种解决方案特别的问题。

在此先感谢

将默认在您的switch语句

default: 
    viewHolder.mImageViewPriority.setBackgroundColor("Default color here for other priorities"); 
break; 

，并把默认值的所有if else条件
