其他的解决方法对我都不起作用。我发现它们都有明显的缺点:

使用滑动转换的解决方案不能使用占位符 使用圆形图像视图的解决方案不适用于动画(即交叉渐隐) 使用父类的通用方法来剪辑子类(即这里接受的答案)的解决方案不能很好地与glide一起工作

有趣的是，在摸索了一番之后，我发现了Fresco图书馆关于圆角和圆的页面，其中他们列出了基本相同的限制，并以声明结尾:

在Android上没有真正好的解决方案，人们必须在上述的权衡中做出选择

令人难以置信的是，在这个时候我们仍然没有一个真正的解决方案。基于上面的链接，我有一个替代的解决方案。这种方法的缺点是它假设你的背景是纯色的(角落不是真正透明的)。你可以这样使用它:

<RoundedCornerLayout ...>
    <ImageView ...>
</RoundedCornerLayout>

要点在这里，完整代码在这里:

public class RoundedCornerLayout extends RelativeLayout {
    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) {
        super(context, attrs, defStyle);
        init(context, attrs, 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) {
        Bitmap mask = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(mask);

        Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
        paint.setColor(Color.WHITE); // TODO set your background color as needed

        canvas.drawRect(0, 0, width, height, paint);

        paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.CLEAR));
        canvas.drawRoundRect(new RectF(0, 0, width, height), cornerRadius, cornerRadius, paint);

        return mask;
    }
}

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" />

你必须使用CircularImageView来显示那种类型的图像…

您正在使用Glide库，用于加载图像..

创建一个类文件在你的项目和加载它在Imageview…你会得到你想要的结果…

试试下面的代码…

XML

 <com.yourpackage.CircularImageView
    android:id="@+id/imageview"
    android:layout_width="96dp"
    android:layout_height="96dp"
    app:border="true"
    app:border_width="3dp"
    app:border_color="@color/white"
    android:src="@drawable/image" />

CircularImageView.java

public class CircularImageView extends ImageView {
    private int borderWidth;
    private int canvasSize;
    private Bitmap image;
    private Paint paint;
    private Paint paintBorder;

    public CircularImageView(final Context context) {
        this(context, null);
    }

    public CircularImageView(Context context, AttributeSet attrs) {
        this(context, attrs, R.attr.circularImageViewStyle);
    }

    public CircularImageView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);

        // init paint
        paint = new Paint();
        paint.setAntiAlias(true);

        paintBorder = new Paint();
        paintBorder.setAntiAlias(true);

        // load the styled attributes and set their properties
        TypedArray attributes = context.obtainStyledAttributes(attrs, R.styleable.CircularImageView, defStyle, 0);

        if(attributes.getBoolean(R.styleable.CircularImageView_border, true)) {
            int defaultBorderSize = (int) (4 * getContext().getResources().getDisplayMetrics().density + 0.5f);
            setBorderWidth(attributes.getDimensionPixelOffset(R.styleable.CircularImageView_border_width, defaultBorderSize));
            setBorderColor(attributes.getColor(R.styleable.CircularImageView_border_color, Color.WHITE));
        }

        if(attributes.getBoolean(R.styleable.CircularImageView_shadow, false))
            addShadow();
    }

    public void setBorderWidth(int borderWidth) {
        this.borderWidth = borderWidth;

    }

    @Override

        // load the bitmap
        image = drawableToBitmap(getDrawable());

        // init shader
        if (image != null) {

            canvasSize = canvas.getWidth();
            if(canvas.getHeight()<canvasSize)
                canvasSize = canvas.getHeight();

            canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, ((canvasSize - (borderWidth * 2)) / 2) + borderWidth - 4.0f, paintBorder);
            canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, ((canvasSize - (borderWidth * 2)) / 2) - 4.0f, paint);
        }
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int width = measureWidth(widthMeasureSpec);
        int height = measureHeight(heightMeasureSpec);
        setMeasuredDimension(width, height);
    }

    private int measureWidth(int measureSpec) {
        int result = 0;
        int specMode = MeasureSpec.getMode(measureSpec);
        int specSize = MeasureSpec.getSize(measureSpec);

        if (specMode == MeasureSpec.EXACTLY) {
            // The parent has determined an exact size for the child.
            result = specSize;
        } else if (specMode == MeasureSpec.AT_MOST) {

        drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
        drawable.draw(canvas);

    }
}

注意:

你可以使用

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

or

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

它不会影响你的其他库…不必改变你的代码下载图像或其他任何东西… 它可以简单地定义使用XML太..

private void setContactImage(@NonNull ViewHolder holder, ClsContactDetails clsContactDetails) {
    Glide.with(context).load(clsContactDetails.getPic())
        .apply(new RequestOptions().centerCrop().circleCrop().placeholder(R.mipmap.ic_launcher)).into(holder.ivPersonImage);
}

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)
