android 代码动态创建遮罩,android 图片遮罩，水印

动态代码：

Bitmap mark = BitmapFactory.decodeResource(this.getResources(), R.drawable.ic_vip_badger);

Bitmap photo = BitmapFactory.decodeResource(this.getResources(), R.drawable.bg_vip_insurance);

Bitmap photoMark = Bitmap.createBitmap(photo.getWidth(), photo.getHeight(), Config.ARGB_8888);

Canvas canvas = new Canvas(photoMark);

canvas.drawBitmap(photo, 0, 0, null);

canvas.drawBitmap(mark, photo.getWidth() - mark.getWidth(), 0, null);

canvas.save(Canvas.ALL_SAVE_FLAG);

canvas.restore();

insurance_vip_imageview.setImageBitmap(photoMark);

使用FrameLayout也可以
