Solución:
Editar: Esto es súper simple ahora con 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)
Estos son algunos otros fragmentos de Glide
Respuesta anterior: También puede crear una barra de progreso normal y luego ocultarla en Glide’s onResourceReady().
El método al que se llamará cuando finalice la carga de recursos.
Ejemplo:
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()
@Override
public boolean onLoadFailed(@Nullable GlideException e, Object model, Target target, boolean isFirstResource)
progressBar.setVisibility(View.GONE);
return false;
@Override
public boolean onResourceReady(Drawable resource, Object model, Target target, DataSource dataSource, boolean isFirstResource)
progressBar.setVisibility(View.GONE);
return false;
)
.into(imageView);
activity_main.xml (diseño):
Resultado:
Puede establecer el valor de progreso lo que quiera con mi GlideImageLoader.
Espero que resuelva tu pregunta.
Encapsulo el cargador de imágenes con el progreso en GlideImageLoader.java y ProgressAppGlideModule .java
Cómo implementar con 3 pasos:
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 y ProgressAppGlideModule.Java en su proyecto
3. Uso simple en cualquier lugar
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);
Código Java completo para clonar:
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
private void onConnecting()
if (mProgressBar != null) mProgressBar.setVisibility(View.VISIBLE);
private void onFinished()
if (mProgressBar != null && mImageView != null)
mProgressBar.setVisibility(View.GONE);
mImageView.setVisibility(View.VISIBLE);
ProgressAppGlideModule.java
@GlideModule
public class ProgressAppGlideModule extends AppGlideModule

super.registerComponents(context, glide, registry);

else
totalBytesRead += bytesRead;
progressListener.update(url, totalBytesRead, fullLength);
return bytesRead;
;
Estaba escribiendo una aplicación en Kotlin y tenía este problema exacto, pero, desafortunadamente, la respuesta aceptada estaba en Java. Entonces, lo reescribí en Kotlin.
Glide.with(context)
.load("")
.listener(object : RequestListener
override fun onResourceReady(resource: Drawable?, model: Any?, target: Target?, dataSource: DataSource?, isFirstResource: Boolean): Boolean
progressBar.visibility = View.GONE
return false
override fun onLoadFailed(e: GlideException?, model: Any?, target: Target?, isFirstResource: Boolean): Boolean
progressBar.visibility = View.GONE
return false
)
.into(holder.imageView)
