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);

        this.borderWidth = borderWidth;
        this.requestLayout();
        this.invalidate();
    }

    public void setBorderColor(int borderColor) {
        if (paintBorder != null)

    public void addShadow() {
        setLayerType(LAYER_TYPE_SOFTWARE, paintBorder);
        paintBorder.setShadowLayer(4.0f, 0.0f, 2.0f, Color.BLACK);
    }

    @Override
    public void onDraw(Canvas canvas) {
        // load the bitmap
        image = drawableToBitmap(getDrawable());

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

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

            BitmapShader shader = new BitmapShader(Bitmap.createScaledBitmap(image, canvasSize, canvasSize, false), Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
            paint.setShader(shader);

            // circleCenter is the x or y of the view's center

        }
    }

    @Override

        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);

        }

        Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(),
                drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bitmap);
        drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
        drawable.draw(canvas);

        return bitmap;
    }
}

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..

Glide 4.6.1版本

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

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();
    }
} 

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;
    }
}

我发现了一个简单的解决方案，为imageview添加边界，其中的颜色想要设置或添加渐变图像。

步骤:

取一帧布局并添加两张图像。您可以根据您的要求设置大小。对于imgPlaceHolder，您需要一个想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>

After placing this code on xml file , put below line in java file. 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的边界简单，没有任何额外的填充和边缘。

注意:白色图像是强制性的边界，否则它将不起作用。

快乐编码:)
