RequestOptions options=new RequestOptions();

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);
        }
    });

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)

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();
}} 

对我来说;.apply(RequestOptions.circleCropTransform())(4.11)未工作。因为我在用ImageButton。当我用(可点击的)ImageView更改时，它工作了，看起来像我想要的样子。
