android - online - Cómo hacer borde para círculo recortar imagen en planeo.

recortar imagen en circulo online

Question

de forma predeterminada, la imagen que se recorta por deslizamiento no tiene borde. Necesito tener un borde en la imagen del círculo.

Answer 1

Basado en la respuesta de @ wadali para que funcione para Glide 4.xy kotlin. No es una esquina redondeada como la respuesta aceptada, sino un círculo completo.

Copie y modifique este código para adaptarlo a su condición.

fun Bitmap.addBorder(borderSize: Float): Bitmap {
    val borderOffset = (borderSize * 2).toInt()
    val radius = Math.min(height / 2, width / 2).toFloat()
    val output = Bitmap.createBitmap(width + borderOffset, height + borderOffset, Bitmap.Config.ARGB_8888)
    val paint = Paint()
    val borderX = width / 2 + borderSize
    val borderY = height / 2 + borderSize
    val canvas = Canvas(output)
    paint.isAntiAlias = true
    canvas.drawARGB(0, 0, 0, 0)
    paint.style = Paint.Style.FILL
    canvas.drawCircle(borderX, borderY, radius, paint)
    paint.xfermode = PorterDuffXfermode(PorterDuff.Mode.SRC_IN)
    canvas.drawBitmap(this, borderSize, borderSize, paint)
    paint.xfermode = null
    paint.style = Paint.Style.STROKE
    paint.color = Color.WHITE
    paint.strokeWidth = borderSize
    canvas.drawCircle(borderX, borderY, radius, paint)
    return output
}

fun <T> ImageView.circleImage(uri: T, borderSize: Float) {
    Glide.with(context)
        .asBitmap()
        .load(uri)
        .apply(RequestOptions.circleCropTransform())
        .into(object : BitmapImageViewTarget(this) {
            override fun setResource(resource: Bitmap?) {
                val circularBitmapDrawable = RoundedBitmapDrawableFactory.create(
                    context.resources,
                    if (borderSize > 0) {
                        resource?.addBorder(borderSize)
                    } else {
                        resource
                    }
                )
                circularBitmapDrawable.isCircular = true
                setImageDrawable(circularBitmapDrawable)
            }
        })
}

¿Cómo utilizar?

yourImageView.circleImage(
        imageUrl,
        borderSizeInPx
)

Answer 2

Dibujable para el borde del círculo de 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" />

y el diseño será así

Asegúrese de que la altura y el ancho de su ImageView sean más bajos que la altura y el ancho de 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>

y configura la imagen con un programador como este

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

Answer 3

Es la mejor manera sin clase extra en Glide V4. +

Glide.with(this)
                .load(url)
                .apply(new RequestOptions().circleCrop())
                .into(view);

    }


    @Override
    public void updateDiskCacheKey(MessageDigest messageDigest) {

    }

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

Ahora en tu Actividad, tienes que poner esto:

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);

Answer 5

Buena manera de hacer esto sin utilizar ningún diseño exterior

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);
        }
    });
}

Para agregar borde con bitmap

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;
}

Answer 6

Es fácil con un diseño exterior:

tu_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"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"/>

    </RelativeLayout>

res / drawable / round_border_style.xml

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

    <item>
        <shape>
        <gradient android:angle="0" android:endColor="@color/white" android:startColor="@color/white" android:centerColor="@color/white" android:gradientRadius="10sp" />
        <corners android:radius="5dp" />
            <stroke android:width="2dp"
                android:color="@color/gray"/>
        </shape>
    </item>

</selector>

Controller.java

GlideApp.with(context).load(url).fitCenter().into(imageView);
