Bạn có thể đặt giá trị tiến độ bất cứ thứ gì bạn muốn với GlideImageLoader của tôi.
Tôi hy vọng nó sẽ giải quyết câu hỏi của bạn.
Tôi đóng gói Trình tải hình ảnh với tiến trình trong GlideImageLoader.java & ProgressAppGlideModule .java
Cách thực hiện với 3 bước:
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. Nhân bản GlideImageLoader.java & ProgressAppGlideModule.Java vào dự án của bạn
3. Sử dụng đơn giản ở mọi nơi
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);
Hoàn thành mã Java cho bản sao:
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);
onFinished();
return false;
}
})
.into(mImageView);
}
private void onConnecting() {

}

}
}
}
