希望有帮助

可以直接继承ImageView

自定义的圆形ImageView

public class RoundImageView extends WebImageView {
int raduis=CampusUtils.dipToPixel(70);
    public RoundImageView(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

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


    @Override
    protected void onDraw(Canvas canvas) {

        Drawable drawable = getDrawable();

        if (drawable == null) {
            return;
        }

        if (getWidth() == 0 || getHeight() == 0) {
            return;
        }

        Bitmap b = null;

        if (drawable instanceof BitmapDrawable) {
            b = ((BitmapDrawable) drawable).getBitmap();
        }

        if (null == b) {
            return;
        }

        Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

        int w = getWidth(), h = getHeight();

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

    }

    public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
        Bitmap sbmp;
        if (bmp.getWidth() != radius || bmp.getHeight() != radius)
            sbmp = Bitmap.createScaledBitmap(bmp, radius, radius, 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(sbmp.getWidth() / 2 + 0.7f,
                sbmp.getHeight() / 2 + 0.7f, sbmp.getWidth() / 2 + 0.1f, paint);
        paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
        canvas.drawBitmap(sbmp, rect, rect, paint);

        return output;
    }
    @Override
    public void setImageBitmap(Bitmap bm) {
        // TODO Auto-generated method stub
        super.setImageBitmap(getCroppedBitmap(bm,raduis));
    }

}
