Anda dapat mengatur nilai kemajuan apa pun yang Anda inginkan dengan GlideImageLoader saya.
Saya harap ini akan menjawab pertanyaan Anda.
Saya merangkum Image loader dengan kemajuan di GlideImageLoader.java & ProgressAppGlideModule .java
Cara menerapkan dengan 3 langkah:
1. build.gradle
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 ke dalam Proyek Anda
3. Penggunaan Sederhana di mana saja
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);
Kode Java lengkap untuk klon:
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();
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;
}
});
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);
onFinished();
return false;
}
})
.into(mImageView);
}
private void onConnecting() {
if (mProgressBar != null) mProgressBar.setVisibility(View.VISIBLE);
}

}
}
}
