滑翔 V4：

        .into(imageView);

滑翔 V3：

您可以使用RoundedBitmapDrawableGlide 制作圆形图像。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);
        }
    });

    .centerCrop()
    .placeholder(R.drawable.loading_spinner)
    .animate(R.anim.fade_in)

其他解决方案对我不起作用。我发现它们都有明显的缺点：

使用滑行变换的解决方案不适用于占位符
使用圆形图像视图的解决方案不适用于动画（即淡入淡出）
使用剪辑其子级的父级的通用方法（即此处接受的答案）的解决方案不适用于 glide

真的很有趣，在摸索之后，我找到了关于圆角和圆的 Fresco 库页面，其中列出了基本相同的限制并以声明结束：

Android 上的圆角没有真正好的解决方案，必须在上述权衡之间做出选择

令人难以置信的是，此时我们仍然没有真正的解决方案。我有一个基于上面链接的替代解决方案。这种方法的缺点是它假设您的背景是纯色（角落不是真正透明的）。你会像这样使用它：

    private Bitmap maskBitmap;
    private Paint paint;
    private float cornerRadius;

    public RoundedCornerLayout(Context context) {
        super(context);
        init(context, null, 0);
    }

    public RoundedCornerLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
        init(context, attrs, 0);
    }

    public RoundedCornerLayout(Context context, AttributeSet attrs, int defStyle) {

    }

    private void init(Context context, AttributeSet attrs, int defStyle) {
        paint = new Paint(Paint.ANTI_ALIAS_FLAG);

        setWillNotDraw(false);
    }

    @Override
    public void draw(Canvas canvas) {
        super.draw(canvas);

        if (maskBitmap == null) {
            // This corner radius assumes the image width == height and you want it to be circular
            // Otherwise, customize the radius as needed
            cornerRadius = canvas.getWidth() / 2;
            maskBitmap = createMask(canvas.getWidth(), canvas.getHeight());
        }

        canvas.drawBitmap(maskBitmap, 0f, 0f, paint);
    }

    private Bitmap createMask(int width, int height) {

我找到了一种简单易用的解决方案，用于在要设置颜色的图像视图上添加边框或在图像上添加渐变。

脚步：

采用一帧布局并添加两个图像。您可以根据需要设置大小。对于imgPlaceHolder，您需要一个要设置的白色图像或颜色。

        <ImageView
            android:id="@+id/imgPlaceHolder"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="center"
            android:src="@drawable/white_bg"/>

        <ImageView
            android:id="@+id/imgPic"
            android:layout_width="190dp"
            android:layout_height="190dp"
            android:layout_gravity="center"
            android:src="@drawable/image01"/>
    </FrameLayout>

将此代码放在 xml 文件中后，将下面的行放在 java 文件中。

Glide.with(this).load(R.drawable.image01).asBitmap().centerCrop().into(new BitmapImageViewTarget(imgPic) {
    @Override
    protected void setResource(Bitmap resource) {
        RoundedBitmapDrawable circularBitmapDrawable =
                RoundedBitmapDrawableFactory.create(getResources(), resource);
        circularBitmapDrawable.setCircular(true);
        imageView.setImageDrawable(circularBitmapDrawable);
    }
});

Glide.with(this).load(R.drawable.white_bg).asBitmap().centerCrop().into(new BitmapImageViewTarget(imgPlaceHolder) {
    @Override
    protected void setResource(Bitmap resource) {
        RoundedBitmapDrawable circularBitmapDrawable =
                RoundedBitmapDrawableFactory.create(getResources(), resource);
        circularBitmapDrawable.setCircular(true);
        imgTemp2.setImageDrawable(circularBitmapDrawable);
    }
});

这将使 imageview 的边框简单地没有任何额外的填充和边距。

注意：白色图像对于边框是强制性的，否则它将不起作用。

快乐编码:)

这是在 Glide 中圆形裁剪位图的更模块化和更简洁的方法：

BitmapTransformation通过扩展then overridetransform方法来创建自定义转换，如下所示：

对于 Glide 4.xx

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) {}

}

对于 Glide 3.xx

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";
    }

}

然后在您需要的 Glide builder 中设置它：

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

希望这可以帮助：）

笔记：

您可以使用

CircularImageView imgIcon = (CircularImageView)findViewById(R.id.imageview);

或者

ImageView imgIcon = (ImageView)findViewById(R.id.imageview);

它不会影响您的其他库...不必更改您的代码以下载图像或其他任何内容...它也可以使用 XML 定义...

不要附加太多placeholder()、transition()等函数，只要像这段代码一样简单，就可以了。

                        Glide.with(mContext)
                            .load(datas.getUser_img())
                            .centerCrop()
                            .into(ivAvator);

使用这个库 实现 'de.hdodenhof:circleimageview:3.1.0' 的简单解决方案

<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);
