1.放到工具类里/** * 获取圆形图片 * @param bitmap 原图 * @return 圆形图片的bitmap */public static Bitmap getRoundedCornerBitmap(Bitmap bitmap) {    Bitmap output = Bitmap.createBitmap(bitmap.getWidth(),            bitmap.getHeight(), Bitmap.Config.ARGB_8888);    Canvas canvas = new Canvas(output);    final int color = 0xff424242;    final Paint paint = new Paint();    final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());    final RectF rectF = new RectF(rect);    final float roundPx = bitmap.getWidth() / 2;    paint.setAntiAlias(true);    canvas.drawARGB(0, 0, 0, 0);    paint.setColor(color);    canvas.drawRoundRect(rectF, roundPx, roundPx, paint);    paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));    canvas.drawBitmap(bitmap, rect, rect, paint);    return output;}/** * 给imageview设置圆形图片 * @param image imageview * @param bitmap 原图 * @return 设置img后的imageview */public static ImageView setRoundConner(ImageView image, Bitmap bitmap) {    bitmap = getRoundedCornerBitmap(bitmap);    image.setImageBitmap(bitmap);    return image;}2.使用BitmapDrawable bd= (BitmapDrawable) getResources().getDrawable(R.drawable.ceshi);Until.setRoundConner(mImageView,bd.getBitmap()).
