Image getting stretched when displayed in rounded imageview

Question

Below is my RoundedImageView class that extends ImageView:

public class RoundedImageView extends ImageView {

public RoundedImageView(Context context) {
             


        

Answer 1

You should resize your bitmap by its width/height rate.

----EDITED---- This will be a more flexible way to do it.

@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(), h = getHeight();
    int radius = w < h ? w : h;

    Bitmap roundBitmap = getCroppedBitmap(bitmap, radius, w, h);
    // roundBitmap= ImageUtils.setCircularInnerGlow(roundBitmap, 0xFFBAB399,
    // 4, 1);
    canvas.drawBitmap(roundBitmap, 0, 0, null);

}

public static Bitmap getCroppedBitmap(Bitmap bmp, int radius, int w, int h) {
    Bitmap sbmp;
    if (bmp.getWidth() != radius || bmp.getHeight() != radius) {
        float _w_rate = 1.0f * radius / bmp.getWidth();
        float _h_rate = 1.0f * radius / bmp.getHeight();
        float _rate = _w_rate < _h_rate ? _h_rate : _w_rate;
        sbmp = Bitmap.createScaledBitmap(bmp, (int)(bmp.getWidth() * _rate), (int)(bmp.getHeight() * _rate), false);
    }
    else
        sbmp = bmp;

    Bitmap output = Bitmap.createBitmap(sbmp.getWidth(), sbmp.getHeight(),
            Config.ARGB_8888);
    Canvas canvas = new Canvas(output);

    final int color = 0xffa19774;
    final Paint paint = new Paint();
    final Rect rect = new Rect(0, 0, sbmp.getWidth(), sbmp.getHeight());

    paint.setAntiAlias(true);
    paint.setFilterBitmap(true);
    paint.setDither(true);
    canvas.drawARGB(0, 0, 0, 0);
    paint.setColor(Color.parseColor("#BAB399"));
    canvas.drawCircle(w / 2, h / 2, (w < h ? w : h) / 2, paint);
    paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
    canvas.drawBitmap(sbmp, rect, rect, paint);

    return output;
}

Another alternative is to create a transparent PNG for the border (a hollowed out circle in a square) and place it as the background of a view directly above, and with the same dimensions, of the ImageView.

Something like this:

EDIT:

Seems white on white images are porblematic :) (trust me, there's an image there...) So I uplaoded 2 more:
