Kotlin： Glide加载图片工具类

最近在学习kotlin,发现代码比java简洁不好，下面是kotlin写的Glide工具类

首先引入lib库：

api 'com.github.bumptech.glide:glide:4.9.0'
api 'jp.wasabeef:glide-transformations:3.3.0'

以下直接上代码：

/**
 * glide工具类

class GlideUtils {

    companion object {

        /**
         * 加载图片(String地址)
         */
        fun loadImage(context: Context, url: String, imageView: ImageView) {
            var strategy = DiskCacheStrategy.NONE
            if (url.startsWith("http://") || url.startsWith("https://")) {
                strategy = DiskCacheStrategy.RESOURCE
            }
            val options =
                RequestOptions().centerCrop().placeholder(R.color.white).error(R.color.white)
                    .dontAnimate().diskCacheStrategy(strategy)
            Glide.with(context).load(url).apply(options).into(imageView)
        }

        /**
         * 加载图片(int资源地址)
         */
        fun loadImage(context: Context, res: Int, imageView: ImageView) {
            var strategy = DiskCacheStrategy.NONE
            val options =
                RequestOptions().centerCrop().placeholder(R.color.white).error(R.color.white)
                    .dontAnimate().diskCacheStrategy(strategy)
            Glide.with(context).load(res).apply(options).into(imageView)
        }
