如何通过Android分享意图在Facebook上与CAPTION分享照片？

问题描述：

我想通过Facebook的分享意向与我的应用程序分享一张预先填写的图片。

I'd like to share a photo with caption pre-filled from my app via a share intent, on facebook.

我知道如何分享照片或如何分享文本，但如何共享？

I know how to share photo or how to share text, but how do I share them together?

示例代码

Intent shareCaptionIntent = new Intent(Intent.ACTION_SEND);
    shareCaptionIntent.setType("image/*");

    //set photo
    shareCaptionIntent.setData(examplePhoto);
    shareCaptionIntent.putExtra(Intent.EXTRA_STREAM, examplePhoto);

    //set caption
    shareCaptionIntent.putExtra(Intent.EXTRA_TEXT, "example caption");
    shareCaptionIntent.putExtra(Intent.EXTRA_SUBJECT, "example caption");

    startActivity(Intent.createChooser(shareCaptionIntent,getString(R.string.share)));

如果设置类型为 image / * 然后上传一张照片，而不填写字幕。如果将它设置为 text / plain 只有标题被上传，没有照片.....

If a set type to image/* then a photo is uploaded without the caption prefilled. If a set it to text/plain only the caption is uploaded without the photo.....

我的猜测是，Android Facebook App不会在 Intent.EXTRA_TEXT 中查找 ACTION_SEND 用于照片上传的类型为 image / * 的意图。 所以如果Android的Facebook应用程序查找该值，那么这个问题可以解决，如果存在的话，将其插入到图片的标题中。

My guess is that the issue is that the Android Facebook App doesn't look for Intent.EXTRA_TEXT when it filters an ACTION_SEND Intent with type image/* for photo uploading. So this issue could be resolved if the Android Facebook App looked for that value, and if present, inserted it as the caption of the image.

答

将此行添加到现有代码中：

Add this line to your existing codes:

shareCaptionIntent.putExtra(Intent.EXTRA_TITLE, "my awesome caption in the EXTRA_TITLE field");

EXTRA_TITLE，EXTRA_SUBJECT和EXTRA_TEXT之间没有明确的区别。所以没有明确的共享协议。我们可以随时尝试。： - ）

There is no clearly defined differences among EXTRA_TITLE, EXTRA_SUBJECT and EXTRA_TEXT. So there is no clear share protocol. We could always try them all. :-)
