Facebook Android SDK 4.14使用详解(5)

UI界面调用方法

public static void publishFacebookStoryByNativeApp(Activity activity, FacebookStoryEntity entity, final Handler handler) { //将要飞翔的数据传过来，发送到工具类的方法里 String link = entity.getLink(); String applicationname = entity.getApplicationName(); String description = entity.getDescription(); String name = entity.getName(); String caption = entity.getCaption(); String picture = entity.getPicture(); AlxFacebookHelper.showFacebookShareDialog(activity, link, description, caption, picture, new AlxFacebookHelper.ShareFacebookCallback() { @Override public void onSuccess() { JLogUtils.i("AlexFB","share fb弹窗框建立成功"); } @Override public void onFailure(String reason) { JLogUtils.i("AlexFB",reason); //执行一些分享失败的动作 } }); }

这样一个分享就ok了。

最后把我自己写的工具类的全部代码都贴出来，里面设置了很多回调用的接口，不要和facebook SDK中的接口搞混了
