Android上的Facebook共享在Android片段中无法正常工作

Question

我在应用程序中使用Facebook sdk应用了Facebook共享对话框。共享有效，但响应不成功。

这是OnCreateView中的代码，用于在适配器中单击按钮后调用Facebook回调管理器。

        mAdapter.SetOnShareClickListener(new PostListAdapter.OnShareClickListener() {
        @Override
        public void onItemClick(View view, int position, Post obj) {

            //create callback
            shareDialog.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() {
                @Override
                public void onSuccess(Sharer.Result result) {
                    Toast.makeText(getContext(), "Share Successful!", Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onCancel() {
                    Toast.makeText(getContext(), "Opz...Share cancel!", Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onError(FacebookException error) {
                    Toast.makeText(getContext(), error.getMessage(), Toast.LENGTH_SHORT).show();
                }
            });

            Picasso.with(getContext()).load(obj.getThumbnail()).into(target);
        }
    });

这是活动结果的代码

    @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    callbackManager.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        if (requestCode == PICK_IMAGE_REQUEST && data != null && data.getData() != null) {
            Bitmap image = null;
            try {
                image = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), data.getData());
            } catch (IOException e) {
                e.printStackTrace();
            }
            SharePhoto photo = new SharePhoto.Builder()
                    .setBitmap(image)
                    .build();

            if (ShareDialog.canShow(SharePhotoContent.class)) {
                SharePhotoContent sharePhotoContent = new SharePhotoContent.Builder()
                        .addPhoto(photo)
                        .build();

                shareDialog.show(sharePhotoContent);
            }
        }
    }


}
