Possible Duplicate:
Open Facebook page from Android app?

是否有信使,其他镜子可以用来打开“Facebook”的镜头并进入一个特定页?

For example, when someone clicks a certain button in my app, I want them to be taken to Facebook to a specific company s public Facebook page. Starting a web browser activity for this is easy, but more than likely the user is not logged in the browser etc...

我认为,如果我可以使用“Intent”(如果存在......的话)来启动“Facebook”的备注,并将用户带入“笔记”。这样,用户就已经站起来,并且能够同网页一样互动。

Does an Intent like this exist? If so, where would I find more information on it? I ve been looking through Facebook s developer documentation but I m not seeing anything about this.

Answer 1

Go to https://graph.facebook.com/<user_name_here> (https://graph.facebook.com/fsintents for instance)
Copy your id

使用这种方法:

public static Intent getOpenFacebookIntent(Context context) {

   try {
    context.getPackageManager().getPackageInfo("com.facebook.katana", 0);
    return new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/<id_here>"));
   } catch (Exception e) {
    return new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/<user_name_here>"));
   }
}

如果用户安装了“Facebook”仪器,这将打开。否则,它将在浏览器上打开Facebook。
