Edit: This is super simple now with the CircularProgressDrawable
build.gradle
implementation "androidx.swiperefreshlayout:swiperefreshlayout:1.1.0"
MyGlideModule.kt
@GlideModule
class MyGlideModule : AppGlideModule()
MainActivity.kt
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val circularProgressDrawable = CircularProgressDrawable(this)
circularProgressDrawable.strokeWidth = 5f
circularProgressDrawable.centerRadius = 30f
circularProgressDrawable.start()
GlideApp.with(applicationContext)
.load("https://raw.githubusercontent.com/bumptech/glide/master/static/glide_logo.png")
.placeholder(circularProgressDrawable)
.into(a_main_image)
}
These are some other Glide snippets
Old answer: You could also create a normal ProgressBar, and then hide it on Glide's onResourceReady()
.
The method that will be called when the resource load has finished.
Example:
MainActivity.java
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ImageView imageView = (ImageView) findViewById(R.id.img_glide);
final ProgressBar progressBar = (ProgressBar) findViewById(R.id.progress);
Glide.with(this)
.load("https://raw.githubusercontent.com/bumptech/glide/master/static/glide_logo.png")
.listener(new RequestListener<Drawable>() {
@Override
public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
progressBar.setVisibility(View.GONE);
return false;
}
@Override
public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
progressBar.setVisibility(View.GONE);
return false;
}
})
.into(imageView);
}
activity_main.xml (layout):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<ProgressBar
android:id="@+id/progress"
android:layout_width="match_parent"
android:layout_height="100dp"
android:visibility="visible" />
<ImageView
android:id="@+id/img_glide"
android:layout_width="match_parent"
android:layout_height="100dp" />
</RelativeLayout>
Result:
You can set progress value whatever you want with my GlideImageLoader.
I hope it will solve your question.
I encapsulate Image loader with progress in GlideImageLoader.java & ProgressAppGlideModule .java
How to implement with 3 steps:
1. build.gradle
//Glide
implementation 'com.github.bumptech.glide:glide:4.4.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.4.0'
implementation 'com.github.bumptech.glide:okhttp3-integration:4.4.0'
2. Clone GlideImageLoader.java & ProgressAppGlideModule.Java into Your Project
3. Simple Use anywhere
RequestOptions options = new RequestOptions()
.centerCrop()
.placeholder(R.drawable.placeholder)
.error(R.drawable.ic_pic_error)
.priority(Priority.HIGH);
new GlideImageLoader(YOUR.imageView,
YOUR.progressBar).load(url,options);
Complete Java code for clone:
GlideImageLoader.java
public class GlideImageLoader {
private ImageView mImageView;
private ProgressBar mProgressBar;
public GlideImageLoader(ImageView imageView, ProgressBar progressBar) {
mImageView = imageView;
mProgressBar = progressBar;
}
public void load(final String url, RequestOptions options) {
if (url == null || options == null) return;
onConnecting();
//set Listener & start
ProgressAppGlideModule.expect(url, new ProgressAppGlideModule.UIonProgressListener() {
@Override
public void onProgress(long bytesRead, long expectedLength) {
if (mProgressBar != null) {
mProgressBar.setProgress((int) (100 * bytesRead / expectedLength));
}
}
@Override
public float getGranualityPercentage() {
return 1.0f;
}
});
//Get Image
Glide.with(mImageView.getContext())
.load(url)
.transition(withCrossFade())
.apply(options.skipMemoryCache(true))
.listener(new RequestListener<Drawable>() {
@Override
public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
ProgressAppGlideModule.forget(url);
onFinished();
return false;
}
@Override
public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
ProgressAppGlideModule.forget(url);

return false;
}
})

I was writing an app in Kotlin and was having this exact problem, but, unfortunately, the accepted answer was in Java. So, I rewrote it in Kotlin.
Glide.with(context)
.load("<Insert Your URL>")
.listener(object : RequestListener<Drawable> {
override fun onResourceReady(resource: Drawable?, model: Any?, target: Target<Drawable>?, dataSource: DataSource?, isFirstResource: Boolean): Boolean {
progressBar.visibility = View.GONE
return false
}
override fun onLoadFailed(e: GlideException?, model: Any?, target: Target<Drawable>?, isFirstResource: Boolean): Boolean {
progressBar.visibility = View.GONE
return false
}
})
.into(holder.imageView)
Yes we can show loader on ImageView using Glide RequestOptions.
1)Use below compile line in app level gradle file.
implementation 'com.github.bumptech.glide:glide:4.8.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0'
2)Add progress_animation.xml file in drawable
<?xml version="1.0" encoding="utf-8"?>
<animated-rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:drawable="@drawable/loader_test"
android:pivotX="50%"
android:pivotY="50%"/>
3)Add below loader_test.png image in drawable
4)Create RequestOption as below
public RequestOptions options = new RequestOptions()
.centerCrop()
.placeholder(R.drawable.progress_animation)
.error(R.drawable.user_image)
.diskCacheStrategy(DiskCacheStrategy.ALL)
.priority(Priority.HIGH)
.dontAnimate()
.dontTransform();
5)Finally use this to load image as below
Glide.with(this).load(//*Your image url*//).apply(options).into(image_view);
Here is my complete solution with a circle loading progress. I think it is better to use requestOptions
attributes to achieve this.
CircularProgressDrawable circularProgressDrawable = new CircularProgressDrawable(context);
circularProgressDrawable.setStrokeWidth(5f);
circularProgressDrawable.setCenterRadius(30f);
circularProgressDrawable.start();
RequestOptions requestOptions = new RequestOptions();
requestOptions.placeholder(circularProgressDrawable);
requestOptions.error(R.drawable.ic_image_not_found);
requestOptions.skipMemoryCache(true);
requestOptions.fitCenter();
glide.load(imagePath) //passing your url to load image.
.load(imagePath)
.apply(requestOptions) // here you have all options you need
.transition(DrawableTransitionOptions.withCrossFade()) // when image (url) will be loaded by glide then this face in animation help to replace url image in the place of placeHolder (default) image.
.listener(requestListener)
.into(view); //pass imageView reference to appear the image.
And you got it.
