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

使用这个转换，它会工作得很好。

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

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

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

    int borderColor = ColorUtils.setAlphaComponent(Color.WHITE, 0xFF);
    int borderRadius = 3;

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

    // TODO this could be acquired from the pool too
    Bitmap squared = Bitmap.createBitmap(source, x, y, size, size);
    if (squared != source) {
        source.recycle();
    }

    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);

    // Prepare the background
    Paint paintBg = new Paint();
    paintBg.setColor(borderColor);
    paintBg.setAntiAlias(true);

    // Draw the background circle
    canvas.drawCircle(r, r, r, paintBg);

    // Draw the image smaller than the background so a little border will be seen
    canvas.drawCircle(r, r, r - borderRadius, paint);

    squared.recycle();

    return result;
}

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

它很简单，我看过Glide图书馆，它非常好的图书馆和论文基础上的volley谷歌的图书馆

使用此库查看圆形图像

https://github.com/hdodenhof/CircleImageView

now

//一个简单的视图

 @Override
 public void onCreate(Bundle savedInstanceState) {
  ...

  CircleImageView civProfilePic = (CircleImageView)findViewById(R.id.ivProfile);
  Glide.load("http://goo.gl/h8qOq7").into(civProfilePic);
}

//对于一个列表:

@Override
public View getView(int position, View recycled, ViewGroup container) {
final ImageView myImageView;
 if (recycled == null) {
    myImageView = (CircleImageView) inflater.inflate(R.layout.my_image_view,
            container, false);
} else {
    myImageView = (CircleImageView) recycled;
}

String url = myUrls.get(position);

Glide.load(url)
    .centerCrop()
    .placeholder(R.drawable.loading_spinner)
    .animate(R.anim.fade_in)
    .into(myImageView);

  return myImageView;
}

以及XML格式

<de.hdodenhof.circleimageview.CircleImageView
   android:id="@+id/ivProfile
   android:layout_width="160dp"
   android:layout_height="160dp"
   android:layout_centerInParent="true"
   android:src="@drawable/hugh"
   app:border_width="2dp"
   app:border_color="@color/dark" />

                Glide.with(MainActivity.this)
                        .load(personPhoto)
                        .transition(withCrossFade(500))
                        .apply(RequestOptions.circleCropTransform())
                        .thumbnail(0.5f)
                        .into(imageView);

            

现在在Glide V4中，你可以直接使用CircleCrop()

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

内置类型

CenterCrop FitCenter CircleCrop

Roman Samoylenko的答案是正确的，只是函数变了。 正确答案是

Glide.with(context)
                .load(yourImage)
                .apply(RequestOptions.circleCropTransform())
                .into(imageView);
