Glide 图片框架

 1        Glide.with(mContext).load(localImagePath)
 2                 .crossFade()//淡入淡出动画
 3                 //设置缩略图 显示原图的10%
 4                 //当全分辨率的目标图片在后台加载完全后，Glide会自动切换显示全像素的图片。
 5                 //设置缩略图 也可以是其他图片
 6                 .thumbnail(0.1f)
 7                 .centerCrop()//缩放 填充iamgeview宽高，图片可能不完全显示
 8                 .placeholder(R.drawable.ic_picture_loading)//占位图
 9                 .error(R.drawable.mis_default_error)//error图
10                 //内存缓存策略 true跳过内存缓存； false默认不跳过内存缓存：注意，跳过内存缓存，还是会缓存到硬盘
11                 .skipMemoryCache(false) 
12                 .diskCacheStrategy(DiskCacheStrategy.NONE)//磁盘缓存策略 不缓存到SD卡
13                 .dontAnimate()//取消淡入淡出动画
14                 .listener(reqlistener)
15                 .into(item_iv);
