您也可以使用这个实现，不过值得注意的是，这个实现是基于匕首柄的

提供程序实现

@Module
@Named("circleCrop")
@InstallIn(SingletonComponent::class)
object AppModule {
    @Singleton
    @Provides
    fun provideGlideInstance(
        @ApplicationContext context: Context
    ) = Glide.with(context).setDefaultRequestOptions(
        RequestOptions()
            .placeholder(R.drawable.logo)
            .error(R.drawable.logo)
            .apply(RequestOptions().circleCropTransform())
            .diskCacheStrategy(DiskCacheStrategy.DATA)
    )
}

依赖注入

@Inject
@Named("circleCrop")
 lateinit var glide: RequestManager

加载图片

    glide.load(hotel.image).into(imgItemSearch)

Glide 4.6.1版本

Glide.with(context)
.load(url)
.apply(RequestOptions.bitmapTransform(new CircleCrop()))
.into(imageView);

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);

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);
        }
    });

根据这个答案，两种语言中最简单的方法是:

科特林：

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

Java:

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

这适用于Glide 4.X.X

看看这篇文章，glide vs毕加索… 编辑:链接的文章并没有指出图书馆之间的重要区别。Glide会自动回收。详见TWiStErRob的评论。

Glide.with(this).load(URL).transform(new CircleTransform(context)).into(imageView);

public static 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 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);

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