我正在利用冰川展示URL图像。 当我有透明的PNG时,它显示出黑色的反向。 是否有任何办法调整山崩,以显示这些透明形象,或至少隐蔽的透明度以达到白人?
感谢。

如果您正在使用,则 它赢得的LOSSLESS在第29号及以下文稿上是透明的。
override fun applyOptions(context: Context, builder: GlideBuilder) {
super.applyOptions(context, builder)
val memoryCacheSizeBytes = 1024 * 1024 * 100 // 100mb
builder.setMemoryCache(LruResourceCache(memoryCacheSizeBytes.toLong()))
builder.setDefaultRequestOptions(requestOptions(context))
builder.apply {
requestOptions(context)
}
}
private fun requestOptions(context: Context): RequestOptions {
val compressFormat = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
Bitmap.CompressFormat.WEBP_LOSSY
} else {
Bitmap.CompressFormat.PNG
}
return RequestOptions()
.signature(
ObjectKey(
System.currentTimeMillis() / (24 * 60 * 60 * 1000)
)
)
.encodeFormat(compressFormat)
.encodeQuality(80)
.diskCacheStrategy(DiskCacheStrategy.RESOURCE)
.skipMemoryCache(false)
}
使用地势和滑坡的原木,而不是可以()和变形(CenterInside())也造成这种情况。
I encountered similar issue recently, with glide version 4.14.2
. By borrowing the idea from this answer s comment, I overcome this problem in glide with a customized bitmap transformation.
class HasAlpha: BitmapTransformation() {
companion object {
private const val ID = "com.bumptech.glide.transformations.HasAlpha"
private val ID_BYTES = ID.toByteArray(CHARSET)
}
override fun updateDiskCacheKey(messageDigest: MessageDigest) {
messageDigest.update(ID_BYTES)
}
override fun transform(pool: BitmapPool, toTransform: Bitmap, outWidth: Int, outHeight: Int): Bitmap {
toTransform.setHasAlpha(true)
return toTransform
}
override fun equals(other: Any?): Boolean {
return other is HasAlpha
}
override fun hashCode(): Int {
return ID.hashCode()
}
}
然后在装上图像时适用上述转变。
Glide.with(this).load(url).transform(HasAlpha()).into(imageView)
我不相信它会在某些版本的冰川中产生暂时的 b,也不相信它会以任何一种透明渠道制作任何形式的图像,而我的设想中的形象是完全透明的。 希望任何人来到这里会有所帮助。
