问题
Im looking for a way to use bitmap as input to Glide. I am even not sure if its possible. It's for resizing purposes. Glide has a good image enhancement with scale. The problem is that I have resources as bitmap already loaded to memory. The only solution I could find is to store images to temporary file and reload them back to Glide as inputStream/file.. Is there a better way to achieve that ?
Please before answering .. Im not talking about output from Glide.. .asBitmap().get() I know that.I need help with input.
Here is my workaround solution:
Bitmap bitmapNew=null;
try {
//
ContextWrapper cw = new ContextWrapper(ctx);
File directory = cw.getDir("imageDir", Context.MODE_PRIVATE);
File file=new File(directory,"temp.jpg");
FileOutputStream fos = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 90, fos);
fos.close();
//
bitmapNew = Glide
.with(ctx)
.load(file)
.asBitmap()
.diskCacheStrategy(DiskCacheStrategy.NONE)
.skipMemoryCache(true)
.into( mActualWidth, mActualHeight - heightText)
.get();
file.delete();
} catch (Exception e) {
Logcat.e( "File not found: " + e.getMessage());
}
I'd like to avoid writing images to internal and load them again.That is the reason why Im asking if there is way to to have input as bitmap
Thanks
回答1:
For version 4 you have to call asBitmap() before load()
GlideApp.with(itemView.getContext())
.asBitmap()
.load(data.getImageUrl())
.into(new SimpleTarget<Bitmap>() {
@Override
public void onResourceReady(Bitmap resource, Transition<? super Bitmap> transition) {}
});
}
More info: http://bumptech.github.io/glide/doc/targets.html

A really strange case, but lets try to solve it. I'm using the old and not cool Picasso, but one day I'll give Glide a try.
Here are some links that could help you :
- Bitmap POC
- Supporting bitmaps topic
- Someone also facing your problem
And actually a cruel but I think efficient way to solve this :
ByteArrayOutputStream stream = new ByteArrayOutputStream();
yourBitmap.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);
I'm not sure if this will help you, but I hope it can make you a step closer to the solution.

This solution is working with Glide V4. You can get the bitmap like this:
Bitmap bitmap = Glide
.with(context)
.asBitmap()
.load(uri_File_String_Or_ResourceId)
.submit()
.get();
Note: this will block the current thread to load the image.

There is little changes according to latest version of Glide. Now we need to use submit() to load image as bitmap, if you do not class submit() than listener won't be called.
here is working example i used today.
Glide.with(cxt)
.asBitmap().load(imageUrl)
.listener(new RequestListener<Bitmap>() {
@Override
public boolean onLoadFailed(@Nullable GlideException e, Object o, Target<Bitmap> target, boolean b) {
Toast.makeText(cxt,getResources().getString(R.string.unexpected_error_occurred_try_again),Toast.LENGTH_SHORT).show();
return false;
}
@Override
public boolean onResourceReady(Bitmap bitmap, Object o, Target<Bitmap> target, DataSource dataSource, boolean b) {
zoomImage.setImage(ImageSource.bitmap(bitmap));
return false;
}
}
).submit();
It is working and I'm getting bitmap from listener.

The accepted answer works for previous versions, but in new versions of Glide use:
RequestOptions requestOptions = new RequestOptions();
requestOptions.placeholder(android.R.drawable.waiting);
requestOptions.error(R.drawable.waiting);
Glide.with(getActivity()).apply(requestOptions).load(imageUrl).into(imageView);

here's another solution which return you a bitmap to set into your ImageView
Glide.with(this)
.load(R.drawable.card_front) // you can pass url too
.asBitmap()
.into(new SimpleTarget<Bitmap>() {
@Override
public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
// you can do something with loaded bitmap here
imgView.setImageBitmap(resource);
}
});

In Kotlin,
Glide.with(this)
.asBitmap()
.load("https://...")
.addListener(object : RequestListener<Bitmap> {
override fun onLoadFailed(
e: GlideException?,
model: Any?,
target: Target<Bitmap>?,
isFirstResource: Boolean
): Boolean {
Toast.makeText(this@MainActivity, "failed: " + e?.printStackTrace(), Toast.LENGTH_SHORT).show()
return false
}
override fun onResourceReady(
resource: Bitmap?,
model: Any?,
target: Target<Bitmap>?,
dataSource: DataSource?,
isFirstResource: Boolean
): Boolean {
//image is ready, you can get bitmap here
return false
}
})
.into(imageView)

Please use Implementation for that is:
implementation 'com.github.bumptech.glide:glide:4.9.0'
Glide.with(this)
.asBitmap()
.load(item.getMarkertOverlayImage())
.into(new CustomTarget <Bitmap>() {
@Override
public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition <? super Bitmap> transition) {
// you can do something with loaded bitmap here
}
@Override
public void onLoadCleared(@Nullable Drawable placeholder) {
}
});

Most of the API's and methods of Glide are now deprecated. Below is working for Glide 4.9 and upto Android 10.
For image URI
Bitmap bitmap = Glide
.with(context)
.asBitmap()
.load(image_uri_or_drawable_resource_or_file_path)
.submit()
.get();
Use Glide as below in build.gradle
implementation 'com.github.bumptech.glide:glide:4.9.0'

For what is is worth, based upon the posts above, my approach:
Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");
Uri imageUri = Uri.withAppendedPath(sArtworkUri, String.valueOf(album_id));
then in the adapter:
// loading album cover using Glide library
Glide.with(mContext)
.asBitmap()
.load(imageUri)
.into(holder.thumbnail);
