Comment créer un ImageView circulaire sous Android?

Comment créer un ImageView arrondi sous Android?

J'ai essayé le code suivant, mais cela ne fonctionne pas bien.

Code:

Bitmap circleBitmap = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);

BitmapShader shader = new BitmapShader (bitmap,  TileMode.CLAMP, TileMode.CLAMP);
Paint paint = new Paint();
Paint.setShader(shader);

Canvas c = new Canvas(circleBitmap);
c.drawCircle(bitmap.getWidth()/2, bitmap.getHeight()/2, bitmap.getWidth()/2, Paint);

imageView.setImageBitmap(circleBitmap);

Image à l'intérieur du cercle:

Enter image description here

Comment puis-je faire ceci?

Moi aussi j'avais besoin d'un ImageView arrondi, j'ai utilisé le code ci-dessous, vous pouvez le modifier en conséquence:

import Android.content.Context;
import Android.graphics.Bitmap;
import Android.graphics.Bitmap.Config;
import Android.graphics.Canvas;
import Android.graphics.Color;
import Android.graphics.Paint;
import Android.graphics.PorterDuff.Mode;
import Android.graphics.PorterDuffXfermode;
import Android.graphics.Rect;
import Android.graphics.drawable.BitmapDrawable;
import Android.graphics.drawable.Drawable;
import Android.util.AttributeSet;
import Android.widget.ImageView;

public class RoundedImageView extends ImageView {

    public RoundedImageView(Context context) {
        super(context);
    }

    public RoundedImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

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

    @Override
    protected void onDraw(Canvas canvas) {

        Drawable drawable = getDrawable();

        if (drawable == null) {
            return;
        }

        if (getWidth() == 0 || getHeight() == 0) {
            return;
        }
        Bitmap b = ((BitmapDrawable) drawable).getBitmap();
        Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

        int w = getWidth();
        @SuppressWarnings("unused")
        int h = getHeight();

        Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
        canvas.drawBitmap(roundBitmap, 0, 0, null);

    }

    public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
        Bitmap sbmp;

        if (bmp.getWidth() != radius || bmp.getHeight() != radius) {
            float smallest = Math.min(bmp.getWidth(), bmp.getHeight());
            float factor = smallest / radius;
            sbmp = Bitmap.createScaledBitmap(bmp,
                    (int) (bmp.getWidth() / factor),
                    (int) (bmp.getHeight() / factor), false);
        } else {
            sbmp = bmp;
        }

        Bitmap output = Bitmap.createBitmap(radius, radius, Config.ARGB_8888);
        Canvas canvas = new Canvas(output);

        final String color = "#BAB399";
        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, radius, radius);

        Paint.setAntiAlias(true);
        Paint.setFilterBitmap(true);
        Paint.setDither(true);
        canvas.drawARGB(0, 0, 0, 0);
        Paint.setColor(Color.parseColor(color));
        canvas.drawCircle(radius / 2 + 0.7f, radius / 2 + 0.7f,
                radius / 2 + 0.1f, Paint);
        Paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
        canvas.drawBitmap(sbmp, rect, rect, Paint);

        return output;
    }

}
