आप मेरी GlideImageLoader के साथ जो भी चाहें प्रगति मूल्य निर्धारित कर सकते हैं।
मुझे उम्मीद है कि यह आपके सवाल को हल कर देगा।
मैं GlideImageLoader.java और ProgressAppGlMModule .java में प्रगति के साथ छवि लोडर को एन्क्रिप्ट करता हूं।
3 चरणों के साथ कैसे लागू करें:
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. क्लोन GlideImageLoader.java और ProgressAppGlideModule.Java एक परियोजना में
3. सरल उपयोग कहीं भी
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);
क्लोन के लिए पूरा जावा कोड:
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
