Android 图片圆角处置

绘制图形时，通过绘制相交的部分来实现，不多说，看代码：

	public static Bitmap getRoundedCornerBitmap(Bitmap sourceBitmap, float roundX, float roundY) {				try {						Bitmap targetBitmap = Bitmap.createBitmap(sourceBitmap.getWidth(), sourceBitmap.getHeight(), Config.ARGB_8888);			Canvas canvas = new Canvas(targetBitmap);			Paint paint = new Paint();			Rect rect = new Rect(0, 0, sourceBitmap.getWidth(), sourceBitmap.getHeight());			RectF rectF = new RectF(rect);			paint.setAntiAlias(true);			canvas.drawARGB(0, 0, 0, 0);			canvas.drawRoundRect(rectF, roundX, roundY, paint);			paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));			canvas.drawBitmap(sourceBitmap, rect, rect, paint);			return targetBitmap;					} catch (Exception e) {			e.printStackTrace();		}				return null;			}
