推荐答案

Facebook的Andr​​oid应用程序不支持以来的 1.9.11 版本这个动作隐含的意图机制。 Facebook目前使用相同的iPhone计划机制 FB：// 或 Facebook的：// 来处理所提到的所有动作<一个HREF =htt​​p://wiki.akosma.com/IPhone_URL_Schemes相对=nofollow>这里。

Facebook android app don't support implicit intent mechanism for this action since 1.9.11 version. Facebook now use the same iPhone scheme mechanism fb:// or facebook://to handle all actions mentioned here.

在这里你可以看到，他们支持FB和Facebook方案。

And here you can see that they support the fb and facebook scheme.

    <activity android:name="com.facebook.katana.IntentUriHandler">
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <data android:scheme="facebook" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data android:scheme="fb" />
        </intent-filter>
    </activity>

根据您的要求，这种方法将处理这两种方案。首先，它会检查，如果Facebook的应用程序被安装，否则将在浏览器中打开Facebook的个人资料页面。

As per your requirement, this method will handle both scenarios. First it will check if the facebook app is installed otherwise it will open facebook profile page in browser.

public Intent getFBIntent(Context context, String facebookId) {

    try {
        // Check if FB app is even installed
        context.getPackageManager().getPackageInfo("com.facebook.katana", 0); 

        String facebookScheme = "fb://profile/" + facebookId;
        return new Intent(Intent.ACTION_VIEW, Uri.parse(facebookScheme)); 
    }
    catch(Exception e) {

        // Cache and Open a url in browser
        String facebookProfileUri = "https://www.facebook.com/" + facebookId;
        return new Intent(Intent.ACTION_VIEW, Uri.parse(facebookProfileUri));
    }

    return null;
}

为了打开与用户配置文件，所有你需要做的Facebook应用程序是：

In order to open the facebook app with a user profile all you need to do is:

Intent facebookIntent = getFBIntent(this, "2347633432");
startActivity(facebookIntent);

** 修改 **

这是你可以调用您的活动上面的方法。这就是它！

This is how you can call the above method in your activity. That's it!

public class AboutActivity extends Activity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_about);

     ImageButton f = (ImageButton)findViewById(R.id.f_logo);
     f.setOnClickListener(new OnClickListener() 
     {  
        public void onClick(View arg0) 
        { 
           // Get the intent
           Intent intent = getFBIntent(AboutActivity.this, "sarmad.waleed.7");

           // Start the activity
           if (intent != null)
                startActivity(intent);
        }
     }); 
   }

   /**
    * Get the facebook intent for the given facebook
    * profile id. If the facebook app is installed, then
    * it will open the facebook app. Otherwise, it will
    * open the facebook profile page in browser.
    *
    * @return - the facebook intent
    */
   private Intent getFBIntent(Context context, String facebookId) {

      try {
         // Check if FB app is even installed
         context.getPackageManager().getPackageInfo("com.facebook.katana", 0); 

         String facebookScheme = "fb://profile/" + facebookId;
         return new Intent(Intent.ACTION_VIEW, Uri.parse(facebookScheme)); 
      }
      catch(Exception e) {

         // Cache and Open a url in browser
         String facebookProfileUri = "https://www.facebook.com/" + facebookId;
         return new Intent(Intent.ACTION_VIEW, Uri.parse(facebookProfileUri));
     }

     return null;
   }
}
