我们可以在facebook上更改link（由android应用程序发布）的图像吗

我们可以在facebook上更改link（由android应用程序发布）的图像吗

我通过我的应用程序在FaceBook上发布了一些链接，但我想在FaceBook的墙上显示其他图片

我的代码是这样的

Intent shareCaptionIntent = new Intent(Intent.ACTION_SEND);
shareCaptionIntent.setType("image/png");
shareCaptionIntent.putExtra(Intent.EXTRA_STREAM, "<URL>");
//set caption
shareCaptionIntent.putExtra(Intent.EXTRA_TEXT, "example caption");
shareCaptionIntent.putExtra(Intent.EXTRA_SUBJECT, "example caption");
startActivity(Intent.createChooser(shareCaptionIntent,getString(R.string.share)));

Intent sharecaptioncontent=新的意图（Intent.ACTION\u SEND）；
setType（“image/png”）；
shareCaptionIntent.putExtra（Intent.EXTRA_STREAM，“”）；
//设置标题
shareCaptionIntent.putExtra（Intent.EXTRA_文本，“示例标题”）；
shareCaptionIntent.putExtra（Intent.EXTRA_主题，“示例标题”）；
startActivity（Intent.createChooser（ShareCaptionContent，getString（R.string.share））；

我还可以看到标题和描述。

如何更改图像并使说明和标题可见，请查找附加图像

否您可以更改您在facebook上发布的图像的链接。当Facebook将数据存储在数据库中时，它会自动生成此链接。

如果您确实需要，您可以使用Android Facebook SDK（更改发布的所有内容）来完成此操作。

如果您只是在进行共享，您正在共享的链接将被Facebook过滤（解析），并获取您正在共享的目标url上定义的元标记

针对您的问题：

<meta property="og:title" content="The Rock" />
<meta property="og:url" content="http://www.imdb.com/title/tt0117500/" />
<meta property="og:image" content="http://ia.media-imdb.com/images/rock.jpg" />
<meta property="og:description" content="A great movie with Sean Connery and Nicolas Cage" />

如果你有权更改这些元标记，那么你可以控制Facebook上显示的文章的图像、标题和描述
