Android Partager l'intention pour facebook-Partager le texte et le lien

je viens de construire ce code et il fonctionne pour moi:

private void shareAppLinkViaFacebook(String urlToShare) {
    try {
        Intent intent1 = new Intent();
        intent1.setClassName("com.facebook.katana", "com.facebook.katana.activity.composer.ImplicitShareIntentHandler");
        intent1.setAction("android.intent.action.SEND");
        intent1.setType("text/plain");
        intent1.putExtra("android.intent.extra.TEXT", urlToShare);
        startActivity(intent1);
    } catch (Exception e) {
        // If we failed (not native FB app installed), try share through SEND
        String sharerUrl = "https://www.facebook.com/sharer/sharer.php?u=" + urlToShare;
        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(sharerUrl));
        startActivity(intent);
    }
}

si vous allez utiliser les intentions régulières de partage Android, alors malheureusement L'intention de partage Facebook ne peut prendre QU'une seule URL (assurez-vous qu'il a http://) et aucun message texte supplémentaire. C'est une limite étrange qui n'a pas vraiment de sens.

vous devez utiliser L'officiel Facebook séparé SDK Android dans votre projet pour obtenir la pleine fonctionnalité de partage. Qui est du travail supplémentaire.

j'ai couru à des questions similaires. Dans le fin, ce que j'ai fait était de la direction de l'intention. S'ils choisissent de partager (dans l'intention de partager android régulier) via Facebook, créer une nouvelle intention de partager qui n'a que l'URL et pousser cela à facebook. Toutes les autres options de partage (twitter, message, e-mail) fonctionneraient normalement.

ma question et ma solution sont ici:

brancher L'Android intentions extras selon la méthode qu'ils choisissent de partager

  String shareBody = "app string text " + act_txt + " more text! Get the app at http://www.appurl.com";

PackageManager pm = view.getContext().getPackageManager();
List<ResolveInfo> activityList = pm.queryIntentActivities(sharingIntent, 0);
for(final ResolveInfo app : activityList) {
     Log.i(TAG, "app.actinfo.name: " + app.activityInfo.name);
    //if((app.activityInfo.name).contains("facebook")) {
          if("com.facebook.katana.ShareLinkActivity".equals(app.activityInfo.name)) {


        sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "http://www.appurl.com");
        startActivity(Intent.createChooser(sharingIntent, "Share idea"));
        break;
    } else {
        sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "app name");
        sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
        startActivity(Intent.createChooser(sharingIntent, "Share"));
        break;
    }
}

dans Lollipop (21), vous pouvez utiliser Intent.EXTRA_REPLACEMENT_EXTRAS pour outrepasser l'intention pour des applications spécifiques.

https://developer.android.com/reference/android/content/Intent.html#EXTRA_REPLACEMENT_EXTRAS

private void doShareLink(String text, String link) {
  Intent shareIntent = new Intent(Intent.ACTION_SEND);
  shareIntent.setType("text/plain");
  Intent chooserIntent = Intent.createChooser(shareIntent, getString(R.string.share_via));

  // for 21+, we can use EXTRA_REPLACEMENT_EXTRAS to support the specific case of Facebook
  // (only supports a link)
  // >=21: facebook=link, other=text+link
  // <=20: all=link
  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    shareIntent.putExtra(Intent.EXTRA_TEXT, text + " " + link);
    Bundle facebookBundle = new Bundle();
    facebookBundle.putString(Intent.EXTRA_TEXT, link);
    Bundle replacement = new Bundle();
    replacement.putBundle("com.facebook.katana", facebookBundle);
    chooserIntent.putExtra(Intent.EXTRA_REPLACEMENT_EXTRAS, replacement);
  } else {
    shareIntent.putExtra(Intent.EXTRA_TEXT, link);
  }

  chooserIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
  startActivity(chooserIntent);
}

dans mon application, J'ai intégré Facebook SDK pour permettre aux utilisateurs de partager la citation [ texte pré-rempli ] sur leur mur. En utilisant FB SDK, il est possible de le faire. Il fonctionne dans mon application et j'ai plus de 5K utilisateurs utilisant le même.

apparemment, ce n'est pas contre la Politique de FB car je n'ai eu aucun avertissement ou un problème où cela n'a pas fonctionné.

le code snippets pour le même peut être trouvé ici,

de Faire toute la les applications Android largement utilisées ont un partage Facebook avec un champ de texte pré-rempli?

utilisez ce code pour partager l'image ,la vidéo,le lien et le texte sur facebook fonctionnant parfaitement
