Glide image from gallery to bitmap variable

I have a variable Bitmap image. I have imageButton in my fragment. I can change image of imageButton with Glide.with().load().into(). But I want not to just change image but to save it into Bitmap variable so I can use it for some other task. I tried this
Bitmap image = Glide.with(getContext()).asBitmap().load(imagePath).submit().get();
imageButton.setImageBitmap(image);
But image of imageButton does not change. What's wrong with first line then? Because I am pretty sure that problem is there but don't understand yet what is exactly wrong.
A solution is to do
Bitmap image = BitmapFactory.
decodeStream(getContext().
getContentResolver().
openInputStream(selectedImage));
imageButton.setImageBitmap(image);
Where selectedImage is Uri selectedImage = data.getData() of onActivityResult method, but it will be total mess because of size of bitmap, so we have to use createScaledBitmap, I don't like it. For some reason Bitmap image = BitmapFactory.decodeFile(imagePath) doesn't work, imageButton just becomes tiny grey square, and I didn't find a solution for this.

first of all why are using the imageButton..use imageView it will good than
imagebutton and it will work

I don't know if you should even think about doing this in some serious project but for now it did what needs to be done for me. Earlier I declared private Bitmap jopa.
Glide.with(getContext()).asBitmap().
load(selectedImage).override(500,500).
into(new CustomTarget<Bitmap>()
{
#Override
public void onResourceReady(#NonNull Bitmap resource, #Nullable Transition<? super Bitmap> transition) {
imgShare.setImageBitmap(resource);
jopa = ((BitmapDrawable)imgShare.getDrawable()).getBitmap();
}
#Override
public void onLoadCleared(#Nullable Drawable placeholder) {
}
});
Now Bitmap jopa can be used for other tasks. I hope. Tested it to change picture of another imageview, it worked, so I'll pray it will work further. Full onActivityResult code here. Don't want question to get too messy

Custom imageview with background and src

I've been using CircleImageView till now. But now I need to add background as well as src. Both these features are available in native ImageView. But when I add background color to CircleImageView, the background becomes square instead of circle. I tried many custom circle imageview but to no avail. Is there any way to achieve this?

Use this RoundedImageView code from github
RoundedImageView

Check my code using glide with normal imageview:
Glide.with(getActivity()).load(dashBoardCompanyInfoModel.getLogo()).asBitmap().into(new BitmapImageViewTarget(ivProfile) {
#Override
protected void setResource(Bitmap resource) {
final RoundedBitmapDrawable circularBitmapDrawable =
RoundedBitmapDrawableFactory.create(getResources(), resource);
circularBitmapDrawable.setCircular(true);
ivProfile.setImageDrawable(circularBitmapDrawable);
}
});

ImageSwitcher load images from url

I'm trying to show images from a URL in a ImageSwitcher. I've tried with:
myImageSwitcher.setImageURI(Uri.parse("http://miurl.com/images/foto01.jpg"));
but it said me this "error":
I/System.out﹕ resolveUri failed on bad bitmap uri: http://miurl.com/images/foto01.jpg
Thanks

I know it is late but because I found a better solution for this, would love to share it with all :)
I had to look at the source code of the default ImageSwitcher and know how it works. Whenever we use ImageSwitcher we set a ViewFactory to it. This ViewFactory creates Views which are then used in the ImageSwitcher. Usually we create an ImageView in the ViewFactory. This ImageView is then used in the ImageSwitcher class to draw the view with the image source specified. Below is the setImageResource() method of the ImageSwitcher class.
public void setImageResource(#DrawableRes int resid){
ImageView image = (ImageView)this.getNextView();
image.setImageResource(resid);
showNext();
}
Let's focus on the first and second line of the method.
ImageView image = (ImageView)this.getNextView();
image.setImageResource(resid);
this.getNextView() gets the view from the ViewFactory and casts the view into an ImageView. And then, the Drawable resource is set to it.
Solution
Now, with these information, let's get to the solution! I'm using Volley's NetworkImageView , but you can use Picasso or Glide too! You just have to change the code a bit.
We need to create a custom ImageSwitcher. Here's my code
MyImageSwitcher.java
public class MyImageSwitcher extends ImageSwitcher {
public MyImageSwitcher(Context context) {
super(context);
}
public MyImageSwitcher(Context context, AttributeSet attrs) {
super(context, attrs);
}
public void setImageUrl(String url) {
NetworkImageView image = (NetworkImageView) this.getNextView();
image.setImageUrl(url, AppController.getInstance().getImageLoader());
showNext();
}
}
Notice the setImageUrl() method. We cast the view we get from getNextView() to a NetworkImageView and set the Url to it. If you want to use Picasso, then just cast it into an ImageView and then use Picasso as it needs to be used.
Activity
MyImageSwitcher imageSwitcher = (MyImageSwitcher) findViewById(R.id.imageSwitcher);
imageSwitcher.setFactory(new ViewSwitcher.ViewFactory() {
public View makeView() {
NetworkImageView myView = new NetworkImageView(getApplicationContext());
myView.setScaleType(ImageView.ScaleType.CENTER_CROP);
myView.setLayoutParams(new ImageSwitcher.LayoutParams(imageSwitcher.getLayoutParams()));
return myView;
}
});
If you want to use Picasso, then just use an ImageView.
Layout
<xyz.farhanfarooqui.loadingimages.MyImageSwitcher
android:id="#+id/imageSwitcher"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
AndroidManifest.xml
Don't forget to include android.permission.INTERNET to your AndroidManifest.xml
Done!
Whenever you want to change the image, do it this way,
imageSwitcher.setImageUrl("http://miurl.com/images/foto01.jpg");

I've solucionated this problem using SliderLayot (https://github.com/daimajia/AndroidImageSlider), but I'll try to do with ImageSwitcher too.

I was trying to achieve the same thing when I landed here. I know it's and old question, but since I don't see an answer, I'll tell you the solution that worked for me.
First of all, I downloaded the image/s that I wanted to show in the imageswitcher and return them as a Bitmap using this code:
InputStream in = new java.net.URL(url).openStream();
Bitmap bitmap = BitmapFactory.decodeStream(in);
Then I set the bitmap in the imageswitcher using imageSwitcher.setImageDrawable(new BitmapDrawable(getResources(), bitmap)).
To use java.net.URL(url).openStream(), you'll need to add <uses-permission android:name="android.permission.INTERNET"> to your AndroidManifest.xmlfile.
Have in mind that you could change the download code to make it better (checking for timeouts for example), but this is just a basic solutions to start from.
Another thing about what you were using, I think you can't use setImageURI() to set an internet resource in your ImageSwitcher. Acording to this post, this method is only for content URIs particular to the Android platform (Note that they are talking about an ImageView in that post, but I think the same goes to this case).

How can you use a loading placeholder that is an animated spinner with image loaders like Glide, Picasso etc?

I am trying to insert a generic loading circle as placeholder while an image is being loaded with an image loader library like Glide or Picasso.
I cannot for the life of me find out how you are supposed to create a rotating drawable from xml.
I tried using an AnimationDrawable in XML by creating an animation-list, but it doesn't even show up (not even static).
I just want to have a simple circle that spins all by itself, all in an xml drawable, so I can pass the id as placeholder to my image loader. If that is not possible please tell me now, so I can save a lot of research :)
EDIT: Some code to make it more clear, I need a spinning drawable for this Glide command:
Glide.with(context)
.load(imageUrl)
.into(imageView)
.placeHolder(R.drawable.spinning_loading_placeholder);
While the image is being loaded a placeholder drawable will be shown where the image will later be. I need a drawable that spins itself.

You can add a ProgressBar element to your layout XML, and then display/hide this element as needed. The ProgressBar View is built in and already animated, no custom AnimationDrawable required.

You can use something like this:
Glide.with(mContext).load(imageUrl).asBitmap().centerCrop().into(new BitmapImageViewTarget(vh.avatarImageView) {
#Override
public void onLoadStarted(Drawable placeholder) {
vh.avatarImageView.setImageDrawable(mContext.getResources().getDrawable(R.drawable.ic_placeholder));
}
#Override
public void onLoadFailed(Exception e, Drawable errorDrawable) {
vh.avatarImageView.setImageDrawable(mContext.getResources().getDrawable(R.drawable.ic_failed_download));
}
#Override
protected void setResource(Bitmap resource) {
RoundedBitmapDrawable circularBitmapDrawable =
RoundedBitmapDrawableFactory.create(mContext.getResources(), resource);
circularBitmapDrawable.setCircular(true);
vh.avatarImageView.setImageDrawable(circularBitmapDrawable);
}
});

ANDROID::GET ID(R.drawable.image) value of the image in a imageview

I would like to store image ID's of the images in ImageView into database....then use these IDs as to change the images in ImageViews dynamically...

Pretty much simpler than you think it is.
The trick is to use Tag, so after you set image to the ImageView, set a tag with value of the Drawable id, afterward you can retrieve the id by getting tag.
public void setImageTag(ImageView imageView, int resId) {
imageView.setImage.... <--- set your image
imageView.setTag(int);
}
public int getImageTag(ImageView imageView) {
return (int)imageView.getTag();
}
