Android上的Android分享图片与主题标签

Question

这是我的问题：我想让我的应用程序能够在Facebook上用自动设置的标签共享图片。我搜索了facebook文档，我尝试了一些代码。

我目前能够登录并发布图片，没有任何问题，但我看不到主题标签（或任何错误）

这是我的代码：

     sharedialog = new ShareDialog(this);

     SharePhoto photo = new SharePhoto.Builder()
                .setBitmap(bitmap)
                .build();
        SharePhotoContent content = new SharePhotoContent.Builder()
                .addPhoto(photo)
                .setShareHashtag(new ShareHashtag.Builder()
                        .setHashtag("#FollowTheSun")
                        .build())

                .build();

        if (sharedialog.canShow(content)) {
            ShareDialog.show(this, content);
        }

我做错了什么？谢谢您的帮助！

请试试这个

public void shareFb() {


    if (isFacebookExist()) {


        if (CheckButton.isChecked()) {


            SharePhoto sharePhoto = new SharePhoto.Builder()
                    .setBitmap(updateImage)//image location
                    .build();


            if (ShareDialog.canShow(SharePhotoContent.class)) {
                SharePhotoContent content = new SharePhotoContent.Builder()
                        .addPhoto(sharePhoto)
                        .setShareHashtag(new ShareHashtag.Builder()
                                .setHashtag("#YOURHASHTAG")
                                .build())
                        .build();
                shareDialog.show(content);
            }

        } else {

            SharePhoto sharePhoto = new SharePhoto.Builder()
                    .setBitmap(updateImage)
                    .build();


            if (ShareDialog.canShow(SharePhotoContent.class)) {
                SharePhotoContent content = new SharePhotoContent.Builder()
                        .addPhoto(sharePhoto)
                        .build();
                shareDialog.show(content);
            }

        }


    } else {
        showToast(" Facebook is not install.");
    }

}
    private boolean isFacebookExist() {

    PackageManager pm = getPackageManager();
    try {
        PackageInfo info = pm.getPackageInfo("com.facebook.katana", PackageManager.GET_META_DATA);
    } catch (PackageManager.NameNotFoundException e) {
        return false;
    }
    return true;
}
