I am attempting to dynamically load an imageview when a user clicks on an object. I have tried.

 if(mImage != null){ mImage.setImageURI(null);}

            Glide.with(itemView).load(imageString).into(mImage);

imagestring is an external string that contains a url to an image. What would be the best way to do this?

Try this:

imageView.setImageBitmap(null);

Moreover you will also need to clear the Glide Cache as it stores the image.

This is how I solved this problem.

Method 1: When the URL changes whenever image changes

Glide.with(DemoActivity.this)
.load(Uri.parse("file://" + imagePath))
.diskCacheStrategy(DiskCacheStrategy.NONE)
.skipMemoryCache(true)
.into(mImage);

diskCacheStrategy() can be used to handle the disk cache and you can skip the memory cache using skipMemoryCache() method.

Method 2: When URL doesn't change, however, image changes

If your URL remains constant then you need to use Signature for image cache.

 Glide.with(yourFragment)
 .load(yourFileDataModel)
 .signature(new StringSignature(yourVersionMetadata))
 .into(yourImageView);

Glide signature() offers you the capability to mix additional data with the cache key.

You can use MediaStoreSignature if you are fetching content from media store. MediaStoreSignature allows you to mix the date modified time, mime type, and orientation of a media store item into the cache key. These three attributes reliably catch edits and updates allowing you to cache media store thumbs. You may StringSignature as well for content saved as Files to mix the file date modified time.

Replace image on an imageview without showing white background , I have one ImageView and a button which, when pressed, loads new image (from disk, asBitmap() on the first load Bitmap bitmap = null; if (drawable Glide .​with(context) .load(imageUrl) .thumbnail(Glide // this thumbnail  Call .override(width, height) during the Glide load and explicitly set a width or height for the image such as: GlideApp.with().load(imageUri).override(500, 500).into(). Try removing android:adjustViewBounds="true" from your ImageView if present and if you not calling .override()

If you want to empty imageview using Glide Try this:

  imageString="";
  Glide.with(itemView).load(imageString).into(mImage);

this worked for me.

Displaying Images with the Glide Library, Glide is an Image Loader Library for Android developed by bumptech and is a library It has been used in many Google open source projects including Google I/O For now, the class is empty but later we will show how it can be used to set GlideApp.with(context) .load("http://via.placeholder.com/300.png") .​into(ivImg);  I'm using Glide inside an ArrayAdapter alongside a ViewAdapter. Each row of the adapter contains an image view and a button for taking a photo, which will then be displayed in the image view. After adding a photo, a new row will be added with an empty image view.

Glide v4 : Caching, Permanent size changes; Clearing the disk cache Resource - Has this image been decoded, transformed, and written to the disk cache before? The available strategies allow you to prevent your load from using or writing to the disk cache  @kanoonsantikul Ah, sorry, the null check is earlier in the flow than I thought, try load(new byte[0] /*won't be used to decode, just satisfy signature*/); but remember that this is a hack of a hack, the better approach is to use a custom model where Glide properly can decide if it's in the cache or not.

Best strategy to load images using Glide, It has been used in many Google open source projects including Many of us use glide for image loading but only some of us know its real power. for this but you can set up a monthly schedule to clear up all the cache. into(ImageView imageView): the target image view into which the image will be placed.

  • So loading the image works, and you want to know how to empty the imageview later?
  • mImagee? e? Typo?
  • yes, i fixed it Z. Thanks for catching that.
  • Hm, Ok, thank you for your time and insight jrb. I've narrowed it down to this adapter knowing the url string has changed, but for some reason the imageviewholder doesn't want to update.
