在 Android 中分享图片和文字

Question

我正在使用下面的代码在 Android 中共享图像和文本。当我选择 Whatsapp 时，它会同时分享图片和文字，但当我选择 Facebook 时，它只会分享图片而没有任何文字！我的代码有什么错误？谢谢

Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(bitmapPath)));
share.putExtra(Intent.EXTRA_TEXT, "Shared via" +  APP_URL);
startActivity(Intent.createChooser(share, "Share Image"));

Answer 1

Facebook 更改了他们的政策，因此您不能同时分享图片和文字。再也不可能了

Answer 2

What's wrong in my code?

可能没什么。 ACTION_SEND 在一个 Intent 中支持 EXTRA_TEXT 或 EXTRA_STREAM，但不支持两者（" ...可以有一个 EXTRA_TEXT 或 EXTRA_STREAM 字段，包含要发送的数据”）。一些 ACTION_SEND 实现将超出记录的协议并尝试同时使用两者。其他人会坚持记录的协议并且只使用一个。在这种情况下，Facebook 可能选择坚持记录的协议，只使用一个协议。

Answer 3

Facebook will not allow you to Share any static text you want.

That's why Facebook have provide it's own Share Dialog to post any text on facebook.

It will take image as static but not text.

So better for facebook share only you use Facebook Share Dialog.

The thing is, if you put a URL in the EXTRA_TEXT field, it does work. It's like they're intentionally stripping out any text.

**Check below links for Integration of Facebook Share.**

Answer 4

You cannot share text with Facebook anymore! Period.

Answer 5

无法使用 Intent 在 Facebook 上一起分享图片和文字。但是如果你想共享两者，那么你必须创建图像和文本的位图。

从这里下载源代码(Share image and text on facebook using intent in android)
