使用glide库，您可以使用以下代码:

Glide.with(context)
    .load(imageUrl)
    .asBitmap()
    .placeholder(R.drawable.user_pic)
    .centerCrop()
    .into(new BitmapImageViewTarget(img_profPic) {
        @Override
        protected void setResource(Bitmap resource) {
            RoundedBitmapDrawable circularBitmapDrawable = RoundedBitmapDrawableFactory.create(context.getResources(), resource);

            circularBitmapDrawable.setCircular(true);
            img_profPic.setImageDrawable(circularBitmapDrawable);
        }
    });

滑翔V4:

    Glide.with(context)
        .load(url)
        .circleCrop()
        .into(imageView);

滑翔V3:

您可以使用RoundedBitmapDrawable圆形图像与Glide。不需要自定义ImageView。

 Glide.with(context).load(url).asBitmap().centerCrop().into(new BitmapImageViewTarget(imageView) {
        @Override
        protected void setResource(Bitmap resource) {
            RoundedBitmapDrawable circularBitmapDrawable =
                    RoundedBitmapDrawableFactory.create(context.getResources(), resource);
            circularBitmapDrawable.setCircular(true);
            imageView.setImageDrawable(circularBitmapDrawable);
        }
    });

为了Glide 4.x.x

use

Glide
  .with(context)
  .load(uri)
  .apply(
      RequestOptions()
        .circleCrop())
  .into(imageView)

医生说

圆形图片:CircleImageView/CircularImageView/RoundedImageView 已知与TransitionDrawable (.crossFade()有问题 .thumbnail()或.placeholder())和动画gif，使用 BitmapTransformation (.circleCrop()将在v4中可用)或 .dontAnimate()来修复这个问题

试试这个方法

code

Glide.with(this)
    .load(R.drawable.thumbnail)
    .bitmapTransform(new CropCircleTransformation(this))
    .into(mProfile);

XML

<ImageView
  android:id="@+id/img_profile"
  android:layout_width="76dp"
  android:layout_height="76dp"
  android:background="@drawable/all_circle_white_bg"
  android:padding="1dp"/>

all_circle_white_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item>
    <shape android:shape="oval">
      <solid android:color="@android:color/white"/>
  </shape>
  </item>
</selector>

我用这个变换库。 - > https://github.com/wasabeef/glide-transformations 圆圈描边宽度是ImageView的填充

在这种情况下，我需要添加阴影，和imageView抬高不工作

实现“com.github.bumptech.glide:滑翔:4.10.0”

XML

<FrameLayout
    android:id="@+id/fl_image"
    android:layout_width="60dp"
    android:layout_height="60dp"
    android:layout_margin="10dp"
    android:background="@drawable/card_circle_background"
    android:elevation="8dp">

    <ImageView
        android:id="@+id/iv_item_employee"
        android:layout_width="60dp"
        android:layout_height="60dp"
        tools:background="@color/colorPrimary" />
</FrameLayout>

可拉的形状

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="oval">
     <solid android:color="@color/white"/>
</shape>

滑翔的配置

Glide.with(this)
    .asBitmap()
    .load(item.image)
    .apply(RequestOptions.circleCropTransform())
    .into(iv_item_employee)

我之前在找它，我用最简单的方法做了它，我希望你会喜欢。

 //crete this method into your Utils class and call this method wherever you want to use.
    //you can set these placeHolder() and error() image static as well. I made it as comment inside this method, then no need to use [placeHolderUrl and errorImageUrl] parameters. remove it from this method.
    public static void loadImage(final Activity context, ImageView imageView, String url, int placeHolderUrl, int errorImageUrl) {
        if (context == null || context.isDestroyed()) return;

        //placeHolderUrl=R.drawable.ic_user;
        //errorImageUrl=R.drawable.ic_error;
            Glide.with(context) //passing context
                    .load(getFullUrl(url)) //passing your url to load image.
                    .placeholder(placeHolderUrl) //this would be your default image (like default profile or logo etc). it would be loaded at initial time and it will replace with your loaded image once glide successfully load image using url.
                    .error(errorImageUrl)//in case of any glide exception or not able to download then this image will be appear . if you won't mention this error() then nothing to worry placeHolder image would be remain as it is.
                    .diskCacheStrategy(DiskCacheStrategy.ALL) //using to load into cache then second time it will load fast.
                    .transform(new CircleTransform(context))//this CircleTransform class help to crop an image as circle.
                    .animate(R.anim.fade_in) // when image (url) will be loaded by glide then this face in animation help to replace url image in the place of placeHolder (default) image.
                    .fitCenter()//this method help to fit image into center of your ImageView
                    .into(imageView); //pass imageView reference to appear the image.
    } 

CircleTransform.java

  public class CircleTransform extends BitmapTransformation {
    public CircleTransform(Context context) {
        super(context);

        if(context==null)
            return;
    }

    private static Bitmap circleCrop(BitmapPool pool, Bitmap source) {
        if (source == null) return null;

        int size = Math.min(source.getWidth(), source.getHeight());
        int x = (source.getWidth() - size) / 2;
        int y = (source.getHeight() - size) / 2;


        Bitmap squared = Bitmap.createBitmap(source, x, y, size, size);

        Bitmap result = pool.get(size, size, Bitmap.Config.ARGB_8888);
        if (result == null) {
            result = Bitmap.createBitmap(size, size, Bitmap.Config.ARGB_8888);
        }

        Canvas canvas = new Canvas(result);
        Paint paint = new Paint();
        paint.setShader(new BitmapShader(squared, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP));
        paint.setAntiAlias(true);
        float r = size / 2f;
        canvas.drawCircle(r, r, r, paint);
        return result;
    }

    @Override
    protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
        return circleCrop(pool, toTransform);
    }

    @Override
    public String getId() {
        return getClass().getName();
    }
}

Fade_in.xml用于渐隐动画。

    <set xmlns:android="http://schemas.android.com/apk/res/android">
<!--THIS ANIMATION IS USING FOR FADE IN -->

<alpha
    android:duration="800"
    android:fromAlpha="0.0"
    android:interpolator="@android:anim/decelerate_interpolator"
    android:toAlpha="1.0" />

最后调用此方法。

Utils.loadImage(YourClassName.this,mImageView,url,R.drawable.ic_user,R.drawable.ic_error);
