相关疑难解决方法(0)

我试图从FB获取用户的个人资料图片并在我的应用程序上以圆形图像显示它.我能够检索并显示Facebook SDK提供的ProfilePictureView小部件中的显示图片.但是当我尝试获取该图像的位图并尝试将其置于圆形图像视图中时,我得到了默认的FB显示图片,如果您没有显示图片,则每个人都会被分配.我无法解决这个问题.我这样做是为了从ProfilePictureView中获取位图并将其设置为我的圆形视图.

if (session == Session.getActiveSession()) {
                if (user != null) {

                    // Set the id for the ProfilePictureView
                    // view that in turn displays the profile picture.

                    profilePictureView.setDrawingCacheEnabled(true);
                    profilePictureView.setProfileId(user.getId());



                    Bitmap bitmap = profilePictureView.getDrawingCache();


                        Bitmap circleBitmap = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);

                        BitmapShader shader = new BitmapShader (bitmap,  TileMode.CLAMP, TileMode.CLAMP);
                        Paint paint = new Paint();
                        paint.setShader(shader);
                        Canvas c = new Canvas(circleBitmap);
                     c.drawCircle(bitmap.getWidth()/2, bitmap.getHeight()/2, bitmap.getWidth()/2, paint);

                        profilePic.setImageBitmap(circleBitmap);
                     //profilePictureView.draw(c);
                     //c.drawCircle(bitmap.getWidth()/2, bitmap.getHeight()/2, bitmap.getWidth()/2, paint);

}

这里profilePic是我想要放置圆形的ImageView,而profilePictureView是具有显示pic的ProfilePictureView id.
