Android共享文本和链接的Android共享意图-Java 学习之路

我正在尝试使用Android分享意图在Facebook上发布内容 . 它看起来像这样：

shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shareIntent.setType("text/plain");
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Free education for all! http://linkd.in/xU8mCc");
startActivity(shareIntent);

所以我的帖子有两个 - 一些文字和一个链接 . 但是当消息在Facebook上发布时，它只有链接，没有消息 . 我尝试了各种附加功能，但没有任何作用

有人遇到过这个问题并解决了吗？我有Facebook应用程序版本1.8.1

编辑：我尝试删除链接，Facebook应用程序不接收我的消息（显示一个空白消息要发布），但不是相反的方式 . 所以看起来应用程序完全忽略了任何纯文本消息 . 我吓坏了！这是fb应用程序中的一个主要错误，根本无法发布文本消息（具有共享意图）？

我刚刚构建了这段代码，它对我有用：

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);
    }
}

如果您打算使用常规Android分享意图，那么不幸的是，Facebook分享意图只能使用一个URL（确保它具有http：//）并且不会添加其他文本消息 . 这是一个奇怪的限制，实际上没有意义 .

您必须在项目中使用实际官方单独的Facebook Android SDK才能获得完整的共享功能 . 这是额外的工作 .

我遇到了类似的问题 . 最后，我所做的是分支意图 . 如果他们选择通过Facebook共享（在常规的Android共享意图中），创建一个只有URL并将其推送到Facebook的新共享意图 . 所有其他共享选项（推特，消息，电子邮件）将正常工作 .

我的问题和解决方案在这里：

Branching the Android Share Intent extras depending on which method they choose to share

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;
    }
}

在Lollipop（21）中，您可以使用 Intent.EXTRA_REPLACEMENT_EXTRAS 来覆盖特定应用的意图 .

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);
}

在我的应用程序中，我集成了Facebook SDK，以便用户在他们的墙上分享报价[预填充文本] . 使用FB SDK，可以执行此操作 . 它适用于我的应用程序，我有超过5K用户使用相同的 .

显然这不违反FB的政策，因为我没有任何警告或问题，这不起作用 .

可以在这里找到相同的代码片段，

Do any widely used Android apps have Facebook sharing with pre-populated text field?
