我正在尝试使用Android共享意图在Facebook上发布内容，代码如下：
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);
我的帖子包含文字和一个链接，但当我在Facebook上发布时，只有链接没有文字。我尝试了各种方法，但都无效。
有人遇到过这个问题并解决了吗？我的Facebook应用程序版本是1.8.1。
编辑：我尝试删除链接，但Facebook应用程序不接受我的消息（显示要发布的空白消息），但反过来却不会出现此问题。看起来应用程序完全忽略了任何纯文本消息。我感到很困惑！这是FB应用程序的一个重大漏洞吗，根本无法发布文本消息（使用共享意图）？
我刚刚构建了这段代码，它对我有效：
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);
}
}
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;
}
}
for循环中使用break？ - Jiechao WangIntent.EXTRA_REPLACEMENT_EXTRAS来覆盖特定应用程序的意图。
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);
}
