Как сделать рамку для обрезанного изображения круга в glide

Версия 4

Я сделал так, класс RoundedCorners:

        strokePaint.setStrokeWidth(mBorder);

        canvas.drawRoundRect(new RectF(mMargin, mMargin, right, bottom), mRadius, mRadius, paint);

        // stroke
        canvas.drawRoundRect(new RectF(mMargin, mMargin, right, bottom), mRadius, mRadius, strokePaint);
    }


    @Override
    public void updateDiskCacheKey(MessageDigest messageDigest) {

    }

    public String getId() {
        return "RoundedTransformation(radius=" + mRadius + ", margin=" + mMargin + ", diameter="
                + mDiameter + ", cornerType=" + mCornerType.name() + ")";
    }
}

Теперь в вашей деятельности вы должны поместить это:

public static int sCorner = 15;
public static int sMargin = 2;
public static int sBorder = 10;
public static String sColor = "#7D9067";


    ...

    ImageView imageView = (ImageView) findViewById(R.id.activity_main_image_view);


    ImageView mImageViewBorder = (ImageView) findViewById(R.id.activity_main_image_view_border);


     ....
            // Rounded corners
        Glide.with(this).load("http://scareface.jpeg")
        .apply(RequestOptions.bitmapTransform(
        new RoundedCornersTransformation(this, sCorner, sMargin))).into(mImageView);

        // Rounded corners with border
        Glide.with(this).load("http://scareface.jpeg")
        .apply(RequestOptions.bitmapTransform(
        new RoundedCornersTransformation(this, sCorner, sMargin, sColor, sBorder))).into(mImageViewBorder);

Вы можете проверить мой пример в github.

Также вы можете проверить этот сообщение и этот библиотека для Версии 3.

Drawable для границы круга ImageView Circle.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">

    <solid android:color="@android:color/transparent" />
    <stroke
        android:width="@dimen/et_thick"
        android:color="@color/profile_pic_round" />

    <corners android:radius="@dimen/default_corner_radius" />

</shape>

и макет будет таким

Убедитесь, что высота и ширина вашего изображения ниже, чем высота и ширина RelativeLayout

<RelativeLayout
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:background="@drawable/circle">// set circle drawable here

    <ImageView
        android:id="@+id/profile_pic"
        android:layout_width="145dp"
        android:layout_height="145dp"
        android:layout_centerInParent="true" />
</RelativeLayout>

и программно установите Image with circuler следующим образом

Glide.with(mContext)
            .load(imagePath)//<= path of image
            .bitmapTransform(new CropCircleTransform(mContext))//<= For Circuler image
            .into(ivProfileImage);//<= your Imageview

На основе ответа @wadali о том, как заставить его работать с языками программирования Glide 4.x и Kotlin. Я также немного оптимизировал код, чтобы он стал чище, вы можете напрямую изменить цвет, а также использовать функцию расширения Kotlin. Это не закругленный угол, как в принятом ответе, а полный круг, как на примере изображения ниже.

Добавьте этот код в свой проект

import android.graphics.*
import android.widget.ImageView
import androidx.core.graphics.drawable.RoundedBitmapDrawableFactory
import com.bumptech.glide.Glide
import com.bumptech.glide.request.RequestOptions
import com.bumptech.glide.request.target.BitmapImageViewTarget

/**
 * Load model into ImageView as a circle image with borderSize (optional) using Glide
 *
 * @param model - Any object supported by Glide (Uri, File, Bitmap, String, resource id as Int, ByteArray, and Drawable)
 * @param borderSize - The border size in pixel
 * @param borderColor - The border color
 */
fun <T> ImageView.loadCircularImage(
    model: T,
    borderSize: Float = 0F,
    borderColor: Int = Color.WHITE
) {
    Glide.with(context)
        .asBitmap()
        .load(model)
        .apply(RequestOptions.circleCropTransform())
        .into(object : BitmapImageViewTarget(this) {
            override fun setResource(resource: Bitmap?) {
                setImageDrawable(
                    resource?.run {
                        RoundedBitmapDrawableFactory.create(
                            resources,
                            if (borderSize > 0) {
                                createBitmapWithBorder(borderSize, borderColor)
                            } else {
                                this
                            }
                        ).apply {
                            isCircular = true
                        }
                    }
                )
            }
        })
}

/**
 * Create a new bordered bitmap with the specified borderSize and borderColor
 *
 * @param borderSize - The border size in pixel
 * @param borderColor - The border color
 * @return A new bordered bitmap with the specified borderSize and borderColor
 */
private fun Bitmap.createBitmapWithBorder(borderSize: Float, borderColor: Int): Bitmap {
    val borderOffset = (borderSize * 2).toInt()
    val halfWidth = width / 2
    val halfHeight = height / 2
    val circleRadius = Math.min(halfWidth, halfHeight).toFloat()
    val newBitmap = Bitmap.createBitmap(
        width + borderOffset,
        height + borderOffset,
        Bitmap.Config.ARGB_8888
    )

    // Center coordinates of the image
    val centerX = halfWidth + borderSize
    val centerY = halfHeight + borderSize

    val paint = Paint()
    val canvas = Canvas(newBitmap).apply {
        // Set transparent initial area
        drawARGB(0, 0, 0, 0)
    }

    // Draw the transparent initial area
    paint.isAntiAlias = true
    paint.style = Paint.Style.FILL
    canvas.drawCircle(centerX, centerY, circleRadius, paint)

    // Draw the image
    paint.xfermode = PorterDuffXfermode(PorterDuff.Mode.SRC_IN)
    canvas.drawBitmap(this, borderSize, borderSize, paint)

    // Draw the createBitmapWithBorder
    paint.xfermode = null
    paint.style = Paint.Style.STROKE
    paint.color = borderColor
    paint.strokeWidth = borderSize
    canvas.drawCircle(centerX, centerY, circleRadius, paint)
    return newBitmap
}

И использовать его

yourImageView.loadCircularImage(
        imageUrl, // or any object supported by Glide
        borderSizeInPx, // default is 0. If you don't change it, then the image will have no border
        Color.RED // optional, default is white
)

Хороший способ сделать это без использования внешнего макета

public static <T> void circleImage(final ImageView imageView, T uri, final boolean border) {
    Glide.with(imageView.getContext()).load(uri).asBitmap().centerCrop().into(new BitmapImageViewTarget(imageView) {
        @Override
        protected void setResource(Bitmap resource) {
            RoundedBitmapDrawable circularBitmapDrawable = RoundedBitmapDrawableFactory.create(imageView.getContext().getResources(), border ? addWhiteBorder(resource, imageView.getContext()) : resource);
            circularBitmapDrawable.setCircular(true);
            imageView.setImageDrawable(circularBitmapDrawable);
        }
    });
}

Для добавления границы с растровым изображением

private static Bitmap addBorder(Bitmap resource, Context context) {
    int w = resource.getWidth();
    int h = resource.getHeight();
    int radius = Math.min(h / 2, w / 2);
    Bitmap output = Bitmap.createBitmap(w + 8, h + 8, Bitmap.Config.ARGB_8888);
    Paint p = new Paint();
    p.setAntiAlias(true);
    Canvas c = new Canvas(output);
    c.drawARGB(0, 0, 0, 0);
    p.setStyle(Paint.Style.FILL);
    c.drawCircle((w / 2) + 4, (h / 2) + 4, radius, p);
    p.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
    c.drawBitmap(resource, 4, 4, p);
    p.setXfermode(null);
    p.setStyle(Paint.Style.STROKE);
    p.setColor(ContextCompat.getColor(context, R.color.colorPrimary));
    p.setStrokeWidth(3);
    c.drawCircle((w / 2) + 4, (h / 2) + 4, radius, p);
    return output;
}

С внешним макетом легко:

ваш_layout.xml

<RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="5dp"
        android:background="@drawable/round_border_style">

        <ImageView
            android:id="@+id/imageView"
