如何在Android中使用Glide设置位图图像

Question

我在我的应用程序中有一个SqliteDatabase，在这个数据库里，我保存字符串和Blob（用于保存图像）。这个图像被保存在应用程序中，以byte[ ]的形式。我使用以下代码将此图像转换为位图：

    byte[] Recycler_imageByte;
    Bitmap Recycler_theImage;

holder.Recycler_imageByte = data.get(position).getKey_image();
ByteArrayInputStream imageStream = new ByteArrayInputStream(holder.Recycler_imageByte);
holder.Recycler_theImage = BitmapFactory.decodeStream(imageStream);

我希望在 Glide 库中显示这张图片，我已经编写了以下代码：

Glide.with(context).load(holder.Recycler_theImage).asBitmap().into(holder.Recycler_adapter_image);

但是，当我运行应用程序时，会显示以下错误：

如何在Glide库中修复并显示位图？

Answer 1

这对我来说完美地运作。您可以尝试以下方法：

@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (resultCode != Activity.RESULT_OK) return;

    if (requestCode == AppConstants.REQUEST_CAMERA_PICK) {
      Bitmap photo = (Bitmap) data.getExtras().get("data");
      ByteArrayOutputStream stream = new ByteArrayOutputStream();
      photo.compress(Bitmap.CompressFormat.PNG, 100, stream);
      Glide.with(this)
          .load(stream.toByteArray())
          .asBitmap()
          .error(R.drawable.ic_thumb_placeholder)
          .transform(new CircleTransform(this))
          .into(imageview);
    }
  }

Answer 2

试试这个。

 Glide.with(this)
             .load(holder.Recycler_theImage)
             .diskCacheStrategy(DiskCacheStrategy.ALL)             
             .asBitmap().into(holder.Recycler_adapter_image);

希望能有所帮助...

谢谢 @SJ143，但是当使用.diskCacheStrategy(DiskCacheStrategy.ALL)时，不知道该怎么用.asBitmap()!!! - erere

好的，请跳过这一部分，继续进行。 - user6059242

asBitmap()必须在Glide 4的load()之前调用，在Glide 3中则必须在其之后调用。 - David
