在我的 Android 应用程序中,我想在官方 Facebook 应用程序中打开指向 Facebook 个人资料的链接(当然,如果安装了该应用程序)。对于 iPhone,存在fb://URL 方案,但在我的 Android 设备上尝试相同的操作会引发ActivityNotFoundException.

是否有机会通过代码在官方 Facebook 应用程序中打开 Facebook 个人资料?

这适用于最新版本:

  1. 转到https://graph.facebook.com/<user_name_here >(例如https://graph.facebook.com/fsintents )
  2. 复制你的身份证
  3. 使用此方法:

    public static Intent getOpenFacebookIntent(Context context) {
    
       try {
        context.getPackageManager().getPackageInfo("com.facebook.katana", 0);
        return new Intent(Intent.ACTION_VIEW, Uri.parse("fb://page/<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 应用程序,这将打开它。否则,它将在浏览器中打开 Facebook。

编辑:由于版本 11.0.0.11.23 (3002850) Facebook App 不再支持这种方式,还有另一种方式,请查看 Jared Rummler 的以下回复。

在 Facebook 版本 11.0.0.11.23 (3002850) 中fb://profile/不再fb://page/起作用。我反编译了 Facebook 应用,发现可以使用fb://facewebmodal/f?href=[YOUR_FACEBOOK_PAGE]. 这是我在生产中使用的方法:

/**
 * <p>Intent to open the official Facebook app. If the Facebook app is not installed then the
 * default web browser will be used.</p>
 *
 * <p>Example usage:</p>
 *
 * {@code newFacebookIntent(ctx.getPackageManager(), "https://www.facebook.com/JRummyApps");}
 *
 * @param pm
 *     The {@link PackageManager}. You can find this class through {@link
 *     Context#getPackageManager()}.
 * @param url
 *     The full URL to the Facebook page or profile.
 * @return An intent that will open the Facebook page/profile.
 */
public static Intent newFacebookIntent(PackageManager pm, String url) {
  Uri uri = Uri.parse(url);
  try {
    ApplicationInfo applicationInfo = pm.getApplicationInfo("com.facebook.katana", 0);
    if (applicationInfo.enabled) {
      // http://stackoverflow.com/a/24547437/1048340
      uri = Uri.parse("fb://facewebmodal/f?href=" + url);
    }
  } catch (PackageManager.NameNotFoundException ignored) {
  }
  return new Intent(Intent.ACTION_VIEW, uri);
}

这不是更容易吗?例如在 onClickListener 中?

try {
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/426253597411506"));
    startActivity(intent);
} catch(Exception e) {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.facebook.com/appetizerandroid")));
}

PS。从 http://graph.facebook.com/[userName] 获取您的 id(大数字)

对于 Facebook 页面:

try {
    intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://page/" + pageId));
} catch (Exception e) {
    intent =  new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/" + pageId));
}

对于 Facebook 个人资料:

try {
    intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/" + profileId));
} catch (Exception e) {
    intent =  new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/" + profileId));
}

...因为没有一个答案指出了区别

两者都在 Nexus 4 上使用 Facebook v.27.0.0.24.15 和 Android 5.0.1 进行了测试

这是 2016 年的方法。它效果很好,而且使用起来非常简单。

在查看 Facebook 发送的电子邮件如何打开 Facebook 应用程序后,我发现了这一点。

// e.g. if your URL is https://www.facebook.com/EXAMPLE_PAGE, you should
// put EXAMPLE_PAGE at the end of this URL, after the ?
String YourPageURL = "https://www.facebook.com/n/?YOUR_PAGE_NAME";
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(YourPageURL));

startActivity(browserIntent);

这是执行此操作的最简单代码

        final String urlFb = "fb://page/"+yourpageid;
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setData(Uri.parse(urlFb));

        // If a Facebook app is installed, use it. Otherwise, launch
        // a browser
        final PackageManager packageManager = getPackageManager();
        List<ResolveInfo> list =
            packageManager.queryIntentActivities(intent,
            PackageManager.MATCH_DEFAULT_ONLY);
        if (list.size() == 0) {
            final String urlBrowser = "https://www.facebook.com/"+pageid;

一种更可重用的方法。

这是我们通常在大多数应用程序中使用的功能。因此,这里有一段可重用的代码来实现这一点。

(在事实方面与其他答案类似。在此处发布只是为了简化并使实现可重用)

"fb://page/不适用于较新版本的 FB 应用程序。您应该使用fb://facewebmodal/f?href=较新的版本。(就像这里另一个答案中提到的那样

这是一个完整的工作代码,目前存在于我的一个应用程序中:

public static String FACEBOOK_URL = "https://www.facebook.com/YourPageName";
public static String FACEBOOK_PAGE_ID = "YourPageName";

//method to get the right URL to use in the intent
public String getFacebookPageURL(Context context) {
        PackageManager packageManager = context.getPackageManager();
        try {
            int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;
            if (versionCode >= 3002850) { //newer versions of fb app
                return "fb://facewebmodal/f?href=" + FACEBOOK_URL;
            } else { //older versions of fb app
                return "fb://page/" + FACEBOOK_PAGE_ID;
            }
        } catch (PackageManager.NameNotFoundException e) {
            return FACEBOOK_URL; //normal web url
        }
    }

如果已安装,此方法将返回正确的应用程序 url,如果未安装应用程序,则返回 web url。

然后按如下方式启动一个意图:

Intent facebookIntent = new Intent(Intent.ACTION_VIEW);
String facebookUrl = getFacebookPageURL(this);
facebookIntent.setData(Uri.parse(facebookUrl));
startActivity(facebookIntent);

这就是你所需要的。

为此,我们需要“Facebook 页面 id”,您可以获取它:

  • 从页面转到“关于”。
  • 转到“更多信息”部分。

水图像介绍

要在指定的个人资料页面上打开 Facebook 应用程序,

你可以这样做:

 String facebookId = "fb://page/<Facebook Page ID>";
  startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(facebookId)));

或者您可以验证何时未安装 facebook 应用程序,然后打开 facebook 网页。

String facebookId = "fb://page/<Facebook Page ID>";
String urlPage = "http://www.facebook.com/mypage";

     try {
          startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(facebookId )));
        } catch (Exception e) {
         Log.e(TAG, "Application not intalled.");
         //Open url web page.
         startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(urlPage)));

    String facebookID = "XXXXXXXXX";

    try {
        int versionCode = getActivity().getApplicationContext().getPackageManager().getPackageInfo("com.facebook.katana", 0).versionCode;

        if(!facebookID.isEmpty()) {
            // open the Facebook app using facebookID (fb://profile/facebookID or fb://page/facebookID)
            Uri uri = Uri.parse("fb://page/" + facebookID);
            startActivity(new Intent(Intent.ACTION_VIEW, uri));
        } else if (versionCode >= 3002850 && !facebookUrl.isEmpty()) {
            // open Facebook app using facebook url
            Uri uri = Uri.parse("fb://facewebmodal/f?href=" + facebookUrl);
            startActivity(new Intent(Intent.ACTION_VIEW, uri));
        } else {
            // Facebook is not installed. Open the browser
            Uri uri = Uri.parse(facebookUrl);

我的答案建立在 joaomgcd 广泛接受的答案之上。如果用户安装了 Facebook,但被禁用(例如通过使用 App Quarantine),此方法将不起作用。将选择 Twitter 应用程序的意图,但由于它被禁用,它将无法处理它。

代替:

context.getPackageManager().getPackageInfo("com.facebook.katana", 0);
return new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/620681997952698"));

您可以使用以下内容来决定要做什么:

PackageInfo info = context.getPackageManager().getPackageInfo("com.facebook.katana", 0);
if(info.applicationInfo.enabled)
    return new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/620681997952698"));

我找到的最佳答案,它工作得很好。

只需在浏览器中转到您在 Facebook 上的页面,右键单击,然后单击“查看源代码”,然后找到page_id属性:您必须page_id在最后一个反斜杠后面的这一行中使用此处:

fb://page/pageID

例如:

Intent facebookAppIntent;
try {
    facebookAppIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://page/1883727135173361"));
    startActivity(facebookAppIntent);

要从您的应用程序启动facebook 页面,让 urlString = "fb://page/your_fb_page_id"

启动facebook messenger让 urlString = "fb-messenger://user/your_fb_page_id"

FB page id 通常是数字。要获取它,请转到查找我的 FB ID输入您的个人资料网址,例如www.facebook.com/edgedevstudio然后单击“查找数字 ID”。

瞧,你现在有了你的 fb 数字 ID。将“your_fb_page_id”替换为生成的数字 ID

 val intent = Intent(Intent.ACTION_VIEW, Uri.parse(urlString))
 if (intent.resolveActivity(packageManager) != null) //check if app is available to handle the implicit intent

您可以检查是否安装了任何 Facebook 应用程序的所有 Facebook 应用程序。为了支持 OS 级别 11,我们需要添加它AndrodiManifest.xml以避免找不到包名称异常 -

<manifest ...
<queries>

    <package android:name="com.facebook.lite" />
    <package android:name="com.facebook.android" />

            ApplicationInfo applicationInfo;

                return applicationInfo.enabled?"com.facebook.katana":"";
            } catch (Exception ignored) {
            }

            //Then check that if the facebook lite is installed or not
            try {
                applicationInfo = pm.getApplicationInfo("com.facebook.lite", 0);
                return applicationInfo.enabled?"com.facebook.lite":"";
            } catch (Exception ignored) {
            }

            //Then check the other facebook app using different package name is installed or not
            try {
                applicationInfo = pm.getApplicationInfo("com.facebook.android", 0);
                return applicationInfo.enabled?"com.facebook.android":"";
            } catch (Exception ignored) {
            }

            try {
                applicationInfo = pm.getApplicationInfo("com.example.facebook", 0);
                return applicationInfo.enabled?"com.example.facebook":"";
            } catch (Exception ignored) {
            }
        }
        return "";
    }

然后启动应用程序 -

if (!TextUtils.isEmpty(isFacebookAppInstalled(context))) {
 /* Facebook App is installed,So launch it. 
  It will return you installed facebook app's package
  name which will be useful to launch the app */

  Uri uri = Uri.parse("fb://facewebmodal/f?href=" + yourURL);
 Intent intent = context.getPackageManager().getLaunchIntentForPackage(isFacebookAppInstalled(context);
                if (intent != null) {
                    intent.setAction(Intent.ACTION_VIEW);
                    intent.setData(uri);
                    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    context.startActivity(intent);
                }
                else {
                    Intent intentForOtherApp = new Intent(Intent.ACTION_VIEW, uri);
                    context.startActivity(intentForOtherApp);
                } 
 }

在 2018 年 10 月回答这个问题。工作代码是使用 pageID 的代码。我刚刚对其进行了测试,它可以正常工作。

public static void openUrl(Context ctx, String url){
    Uri uri = Uri.parse(url);
    if (url.contains(("facebook"))){
        try {
            ApplicationInfo applicationInfo = ctx.getPackageManager().getApplicationInfo("com.facebook.katana", 0);
            if (applicationInfo.enabled) {
                uri = Uri.parse("fb://page/<page_id>");
                openURI(ctx, uri);
                return;
            }
        } catch (PackageManager.NameNotFoundException ignored) {
            openURI(ctx, uri);
            return;
        }
    }

我在 webview 中使用 fragment- inside oncreate 以这种形式实现:

 webView.setWebViewClient(new WebViewClient()
{
    public boolean shouldOverrideUrlLoading(WebView viewx, String urlx)
                {
     if(Uri.parse(urlx).getHost().endsWith("facebook.com")) {
                        {
                            goToFacebook();
                        }
                        return false;
                    }
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(urlx));
                    viewx.getContext().startActivity(intent);
                    return true;
                }

});

在 onCreateView 之外:

 private void goToFacebook() {
        try {
            String facebookUrl = getFacebookPageURL();
            Intent facebookIntent = new Intent(Intent.ACTION_VIEW);
            facebookIntent.setData(Uri.parse(facebookUrl));
            startActivity(facebookIntent);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    //facebook url load
    private String getFacebookPageURL() {
        String FACEBOOK_URL = "https://www.facebook.com/pg/XXpagenameXX/";
        String facebookurl = null;

        try {
            PackageManager packageManager = getActivity().getPackageManager();

            if (packageManager != null) {
                Intent activated = packageManager.getLaunchIntentForPackage("com.facebook.katana");

                if (activated != null) {
                    int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;

                    if (versionCode >= 3002850) {
                        facebookurl = "fb://page/XXXXXXpage_id";
                    }
                } else {
                    facebookurl = FACEBOOK_URL;
                }
            } else {
                facebookurl = FACEBOOK_URL;
            }
        } catch (Exception e) {
            facebookurl = FACEBOOK_URL;
        }
        return facebookurl;
    }

答案对我有用,但缺少的一件事是在清单中添加查询,这是我的解决方案:

private void openFacebookApp() {
String facebookUrl = "www.facebook.com/XXXXXXXXXX";
String facebookID = "XXXXXXXXX";

try {
    int versionCode = getActivity().getApplicationContext().getPackageManager().getPackageInfo("com.facebook.katana", 0).versionCode;

    if(!facebookID.isEmpty()) {
        // open the Facebook app using facebookID (fb://profile/facebookID or fb://page/facebookID)
        Uri uri = Uri.parse("fb://page/" + facebookID);
        startActivity(new Intent(Intent.ACTION_VIEW, uri));
    } else if (versionCode >= 3002850 && !facebookUrl.isEmpty()) {
        // open Facebook app using facebook url
        Uri uri = Uri.parse("fb://facewebmodal/f?href=" + facebookUrl);
        startActivity(new Intent(Intent.ACTION_VIEW, uri));
    } else {
        // Facebook is not installed. Open the browser
        Uri uri = Uri.parse(facebookUrl);
        startActivity(new Intent(Intent.ACTION_VIEW, uri));
    }
} catch (PackageManager.NameNotFoundException e) {
    // Facebook is not installed. Open the browser
    Uri uri = Uri.parse(facebookUrl);
    startActivity(new Intent(Intent.ACTION_VIEW, uri));
}

}

并将其添加到应用程序标签之外的清单中

    <queries>
    <package android:name="com.google.android.gm" />
    <package android:name="com.facebook.katana" />
    <intent>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="https" />
    </intent>
    <intent>
        <action android:name="android.intent.action.DIAL" />
        <data android:scheme="tel" />
    </intent>
    <intent>
        <action android:name="android.intent.action.SEND" />
        <data android:mimeType="*/*" />
    </intent>
</queries>

您可以点击按钮打开 Facebook 应用程序,如下所示:-

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

    this.findViewById(R.id.button1).setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            startNewActivity("com.facebook.katana");
        }
    });

}

public void startNewActivity( String packageName)
{
    Intent intent = MainActivity.this.getPackageManager().getLaunchIntentForPackage(packageName);
    if (intent != null)
    {
        // we found the activity
        // now start the activity
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);
    }
    else
    {
        // bring user to the market
        // or let them choose an app?
        intent = new Intent(Intent.ACTION_VIEW);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.setData(Uri.parse("market://details?id="+packageName));
        startActivity(intent);
    }
}
