如何在Android的Glide中设置位图图像 [英] How to set bitmap image in Glide on Android

问题描述

我的应用程序中有一个SqliteDatabase.在此数据库中，我保存了 Sting 和 Blob(用于保存图像).此图像使用 byte [] 保存在应用程序中.我借助以下代码将该图像转换为Bitmap:

I have a SqliteDatabase in my application. In this database, I save Sting and Blob(for save image). This image is saved in application with byte[ ]. I convert this image to Bitmap with the help of following code:

    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);

我想在Glide库中显示此图像，我编写了以下代码:

I want to show this image in Glide libary, I have written the following code:

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

但是，当我运行应用程序时，显示以下错误:

But, when I run application, following error is shown:

如何修复它并在Glide库中显示位图?

How can I fix it and show bitmap in Glide library?

推荐答案

这非常适合我.您可以尝试以下方法，

This works perfectly for me. You can try the following ,

@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);
    }
  }
