Question

我正在将base64转换为图像，但是当我将其设置为imageView时，它什么也没显示。

我已经尝试了几乎所有可用于stackoverflow的解决方案，但结果相同。这就是我现在正在尝试的方式

var iconBase64String = "myBASE64StringWhichIsGivenBelow"
// remove 'data:image/svg+xml;base64,' from start of string
iconBase64String = iconBase64String.substring(iconBase64String.indexOf(",")  + 1)
val image = findViewById<ImageView>(R.id.imageView)

val imageAsBytes = Base64.decode(iconBase64String.toByteArray(), Base64.DEFAULT)
val decodedString = Base64.decode(iconBase64String, Base64.DEFAULT)
val bitmap = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.size)
image.setImageBitmap(bitmap)

我也尝试过使用glide

var iconBase64String = "myBASE64StringWhichIsGivenBelow"
// remove 'data:image/svg+xml;base64,' from start of string
iconBase64String = iconBase64String.substring(iconBase64String.indexOf(",")  + 1)
val image = findViewById<ImageView>(R.id.imageView)

val imageAsBytes = Base64.decode(iconBase64String.toByteArray(), Base64.DEFAULT)
Glide.with(this)
      .asBitmap()
      .load(imageAsBytes)
      .into(image)

这是我要转换的base64：

您可以使用滑行显示图片

          String photoId="base64value"
          Glide.with(getApplicationContext())
            .load(photoId)
            .apply(RequestOptions.circleCropTransform())  //If you get circule
            .into(employeeImage); //xml file name

将base64转换为图像无法正常工作
