在 Android 中打开 Facebook Messenger

Question

我想通过代码打开facebook Messenger。我怎样才能获得facebook ID？我的应用程序上有 facebook SDK，我为每个用户保存了 facebookId，但与我需要的不一样

这是我的方法：

// Make sure the Facebook Messenger for Android client is installed
        boolean isFBInstalled = isAppInstalled("com.facebook.orca");

        if (!isFBInstalled) {
            Toast.makeText(this,"Facebook messenger isn't installed. Please download the app first.", Toast.LENGTH_SHORT)
                    .show();
        }

        else {
            // Create the Intent
            Uri uri = Uri.parse("fb-messenger://user/");
            uri = ContentUris.withAppendedId(uri,Long.valueOf(facebookIDhere);
            Intent intent = new Intent(Intent.ACTION_VIEW, uri);

            try {
                startActivity(intent);
            }

            catch(Exception e) {
                Toast.makeText(this,"Oups!Can't open Facebook messenger right now. Please try again later.", Toast.LENGTH_SHORT)
                        .show();
            }
        }

        return;

Answer 1

转到某人的 Facebook 个人资料。右键单击个人资料图片并复制链接地址。将其粘贴到文本编辑器上，您将在 URL 末尾看到“referrer_profile_id”参数。它是该用户的 Facebook ID。

Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://messaging/" + FbUserID));
startActivity(i);

Answer 2

你可以像这样打开它，无需FB ID

Intent intent= new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_TEXT, "Hello");
intent.setType("text/plain");
intent.setPackage("com.facebook.orca");

try
{
    startActivity(intent);
}
catch (ActivityNotFoundException ex) 
{
    Toast.makeText(this,
           "Oups!Can't open Facebook messenger right now. Please try again later.", 
            Toast.LENGTH_SHORT).show();
}
