android开发使用Glide加载Bitmap的方法

方法一：不推荐，会出现闪烁

fun loadBitmapImage(target: ImageView, bitmap: Bitmap) {
    val baos = ByteArrayOutputStream()
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos)
    val bytes: ByteArray = baos.toByteArray()
    val requestOptions = RequestOptions().centerCrop()
    Glide.with(target.context)
        .setDefaultRequestOptions(requestOptions)
        .load(bytes)
        .into(target)
    baos.closeQuietly()
}

方法二：推荐
fun loadBitmapImage(target: ImageView, bitmap: Bitmap) {
        val drawable = BitmapDrawable(target.resources, bitmap)
        val requestOptions = RequestOptions().centerCrop()
            .diskCacheStrategy(DiskCacheStrategy.ALL)
            .error(drawable)　　//放在出错位置
            .placeholder(drawable)　　//放在占位符位置
        Glide.with(target.context)
            .setDefaultRequestOptions(requestOptions)
            .load("https://${System.currentTimeMillis()}")　　//随便给个不可用的url
            .into(target)
    }
