这里有一个更模块化和更清晰的方法来在Glide中循环裁剪你的位图:

通过扩展BitmapTransformation创建一个自定义转换，然后重写transform方法，如下所示:

为了Glide 4.x.x

public class CircularTransformation extends BitmapTransformation {

@Override
protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
    RoundedBitmapDrawable circularBitmapDrawable =
            RoundedBitmapDrawableFactory.create(null, toTransform);
    circularBitmapDrawable.setCircular(true);
    Bitmap bitmap = pool.get(outWidth, outHeight, Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    circularBitmapDrawable.setBounds(0, 0, outWidth, outHeight);
    circularBitmapDrawable.draw(canvas);
    return bitmap;
    }

@Override
public void updateDiskCacheKey(MessageDigest messageDigest) {}

}

为了Glide 3.x.x

public class CircularTransformation extends BitmapTransformation {

@Override
protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
    RoundedBitmapDrawable circularBitmapDrawable =
            RoundedBitmapDrawableFactory.create(null, toTransform);
    circularBitmapDrawable.setCircular(true);
    Bitmap bitmap = pool.get(outWidth, outHeight, Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    circularBitmapDrawable.setBounds(0, 0, outWidth, outHeight);
    circularBitmapDrawable.draw(canvas);
    return bitmap;
    }

@Override
public String getId() {
    // Return some id that uniquely identifies your transformation.
    return "CircularTransformation";
    }

}

然后在Glide builder中设置你需要它的地方:

Glide.with(yourActivity)
   .load(yourUrl)
   .asBitmap()
   .transform(new CircularTransformation())
   .into(yourView);

希望这对你有所帮助。

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

简单的解决方案 通过使用这个库 实现“de.hdodenhof: circleimageview: 3.1.0”

<de.hdodenhof.circleimageview.CircleImageView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/profile_image"
android:layout_width="96dp"
android:layout_height="96dp"
android:src="@drawable/profile"
app:civ_border_width="2dp"
app:civ_border_color="#FF000000"/>

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

最简单的方法(需要Glide 4.x.x)

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

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);

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);
        }
    });
