Glide를 사용하여 이미지를로드하는 동안 진행률 표시 줄

Glide를 사용하여 이미지를로드하는 동안 진행률 표시 줄

---

Glide를 사용하여 이미지를로드 할 때까지 회전 애니메이션이있는 자리 표시 자에 스피너를로드 할 수 있습니까?

.placeholder (R.Drawable.spinner) 사용하여 애니메이션이 나오지 않습니까?

누군가 나를 도울 수 있다면 좋을까요?

감사!

편집 : 이것은 (지원 라이브러리) 에서 출시 된 CircularProgressDrawable로 이제 매우 간단합니다 26.1.0.

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)
}

이전 답변 : 일반 ProgressBar 를 만든 다음 Glide의 onResourceReady () 에서 숨길 수도 있습니다.

리소스로드가 완료되면 호출 될 메서드입니다.

예 :

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 (레이아웃) :

<?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>

내 GlideImageLoader를 사용하여 원하는대로 진행 값을 설정할 수 있습니다.

질문이 해결되기를 바랍니다.

GlideImageLoader.java 및 ProgressAppGlideModule .java에서 진행률과 함께 이미지 로더를 캡슐화합니다.

3 단계로 구현하는 방법 :

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. GlideImageLoader.java 및 ProgressAppGlideModule.Java를 프로젝트에 복제

3. 어디서나 간단하게 사용

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);

복제를위한 완전한 Java 코드 :

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() {
        if (mProgressBar != null) mProgressBar.setVisibility(View.VISIBLE);
    }

    private void onFinished() {
        if (mProgressBar != null && mImageView != null) {
            mProgressBar.setVisibility(View.GONE);

나는 Kotlin으로 앱을 작성하고 있었고 정확한 문제가 있었지만 안타깝게도 허용되는 대답은 Java였습니다. 그래서 Kotlin에서 다시 작성했습니다.

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)

Another trick: Put your ImageView inside a RelativeLayout with a ProgressBar behind it. Then load the image via Glide or Picasso. It will do the job for you without any deep digging. You don't need to hide or show the progressbar anymore. It will be fully overlapped by the image.

<RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="@dimen/_180sdp">
            <ProgressBar
                android:layout_centerInParent="true"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"/>
            <ImageView
                android:id="@+id/iv_image"
                android:layout_width="match_parent"
                android:layout_height="@dimen/_180sdp"
                android:scaleType="centerCrop"/>
</RelativeLayout>

Try using RequestOptions

RequestOptions requestOptions = new RequestOptions();
requestOptions.placeholder(R.drawable.ic_placeholder);
requestOptions.error(R.drawable.ic_error);


Glide.with(MainActivity.this)
            .load(url)
            .apply(requestOptions)
            .into(imageview);

This is the one way you can implement loading image using with Glide.

---

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);
