Android：如何通过意图在 facebook 上与文本共享图像？

Android: How to share image with text on facebook via intent?

提问by Mansi

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

我想通过分享意图在 facebook 上分享一张从我的应用程序中预先填充的带有标题的照片。

Example code

示例代码

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

intent.putExtra(Intent.EXTRA_TEXT, "eample");
intent.putExtra(Intent.EXTRA_TITLE, "example");
intent.putExtra(Intent.EXTRA_SUBJECT, "example");
intent.putExtra(Intent.EXTRA_STREAM, imageUri);

Intent openInChooser = new Intent(intent);
openInChooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);
startActivity(openInChooser);

Here is screen shot what I get

这是我得到的屏幕截图

If a set type to image/* then a photo is uploaded without the text prefilled. If a set it to text/plain photo is not display.....

如果将类型设置为 image/* 则上传的照片没有预填充文本。如果将其设置为文本/普通照片不显示.....

The newest Facebook versions doesn't allow you to share text using intents. You have to use the Facebook SDK to do it - to make that simple, use the Facebook SDK + Android Simple Facebook (https://github.com/sromku/android-simple-facebook). Using the library, your code would be like this (extracted from the Simple Facebook site):

最新的 Facebook 版本不允许您使用意图共享文本。您必须使用 Facebook SDK 来做到这一点 - 为简单起见，请使用 Facebook SDK + Android Simple Facebook ( https://github.com/sromku/android-simple-facebook)。使用该库，您的代码将如下所示（摘自 Simple Facebook 站点）：

Publish feed

Set OnPublishListenerand call for:

设置OnPublishListener并调用：

• publish(Feed, OnPublishListener)without dialog.

Update on 14 December 2015

2015 年 12 月 14 日更新

according to New Facebook SDK.

根据新的 Facebook SDK。

facebook-android-sdk:4.6.0

facebook-android-sdk:4.6.0

It's very Simple.
1. create Provider in Android.manifest.xml

这很简单。
1.在里面创建ProviderAndroid.manifest.xml

<provider
            android:authorities="com.facebook.app.FacebookContentProvider{APP_ID}"
            android:name="com.facebook.FacebookContentProvider"
            android:exported="true" />

2. Create Your Share Intent with Data.

2. 用数据创建你的分享意图。

ShareHashtag shareHashTag = new ShareHashtag.Builder().setHashtag("#YOUR_HASHTAG").build();
ShareLinkContent shareLinkContent = new ShareLinkContent.Builder()
                .setShareHashtag(shareHashTag)
                .setQuote("Your Description")
                .setContentUrl(Uri.parse("image or logo [if playstore or app store url then no need of this image url]"))
                .build();

3. Show The Share Dialog

3. 显示共享对话框

ShareDialog.show(ShowNavigationActivity.this,shareLinkContent);

That's It.

就是这样。

As of 2017, facebook doesn't allow sharing of an image + text together, directly from your app.

截至 2017 年，Facebook 不允许直接从您的应用共享图像 + 文本。

Workaround

解决方法

Facebook will though, scrape a URL for title and image data and will use that in a share post.

不过，Facebook 会抓取标题和图像数据的 URL，并将其用于分享帖子。

As a workaround you could create a single page application* that dynamically loads the text/image you want to share (specified in the URL) and you can facebook-share that URL.

作为一种解决方法，您可以创建一个单页应用程序*，动态加载您想要共享的文本/图像（在 URL 中指定），并且您可以通过 Facebook 共享该 URL。

Notes:

笔记：

• Ensure your single page application produces a static page which has its title, open graph meta tags, and images set prior to facebook's page scrape. If these web page tags are changed dynamically through Javascript, facebook will not be able to scrape those values and use them in its share post.
• Use open graph meta property tags og:image:height and og:image:width to allow facebook to create an image previewwithin its share post

• 确保您的单页应用程序生成一个静态页面，该页面具有其标题、开放图形元标记和在 facebook 页面抓取之前设置的图像。如果这些网页标签通过 Javascript 动态更改，facebook 将无法抓取这些值并在其共享帖子中使用它们。
• 使用开放图元属性标签 og:image:height 和 og:image:width 允许facebook在其共享帖子中创建图像预览

Steps

脚步

0) add the latest facebook-sdk libraryto your build.gradle file

0) 将最新的 facebook-sdk 库添加到您的 build.gradle 文件中

compile group: 'com.facebook.android', name: 'facebook-android-sdk', version: '4.25.0'

1) In your AndroidManifest.xml, add a meta-data tag within your <application>section:

1) 在您的 AndroidManifest.xml 中，在您的<application>部分中添加一个元数据标记：

<application android:label="@string/app_name" ...>
...
    <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/>
...
</application>

Add a facebook_app_id string (with your APP ID) to your strings.xml file:

将 facebook_app_id 字符串（带有您的 APP ID）添加到您的 strings.xml 文件中：

<string name="facebook_app_id">12341234</string>

YOURFBAPPID is your Facebook App ID number found at https://developers.facebook.com/apps/

YOURFBAPPID 是您在https://developers.facebook.com/apps/ 上找到的 Facebook 应用 ID 号

2) also add a <provider>tag outside of your <application>tag in AndroidManifest.xml

2)在 AndroidManifest.xml 中的<provider>标签之外添加一个标签<application>

<provider android:authorities="com.facebook.app.FacebookContentProviderYOURFBAPPID"
          android:name="com.facebook.FacebookContentProvider"
          android:exported="true"/>

3) Create a ShareLinkContent object using their builder:

3）使用他们的构建器创建一个 ShareLinkContent 对象：

ShareLinkContent fbShare = new ShareLinkContent.Builder()
            .setContentUrl(Uri.parse("http://yourdomain.com/your-title-here/someimagefilename"))
            .build();

4) Share it from your fragment (or activity, etc.):

4）从您的片段（或活动等）中分享：

ShareDialog.show(getActivity(), fbShare);

FB no longer allows you to prefill the sharing message.

FB 不再允许您预填充共享消息。

In order to circumvent this, you will need to use an SDK to publish via a Graph request. For this you will need the publish_actionspermission. Since last month you need to submit your app to a review processto gain access to publish_actions. Which you would fail if your app prefills the sharing texts. Trust me - I've had the Chutzppah to try.

为了避免这种情况，您需要使用 SDK 通过 Graph 请求进行发布。为此，您需要获得publish_actions许可。从上个月开始，您需要将您的应用提交到审核流程才能访问publish_actions. 如果您的应用预填充共享文本，您将失败。相信我 - 我已经尝试过 Chutzppah。

So it looks like we would have to comply.

所以看起来我们必须遵守。

B.t.w. in iOS you can still prefill the texts using the FB sdk. Who knows for how long.

顺便说一句，在 iOS 中，您仍然可以使用 FB sdk 预填充文本。谁知道多久。

In this Formula you can share image both Messenger and Instagram(com.instagram.android) without using any Provider in "AndroidManifest

在此公式中，您可以共享 Messenger 和 Instagram(com.instagram.android) 图像，而无需使用“AndroidManifest

public void shareMessenger(View v) {
    // showToast("checking");

    File dir = new File(Environment.getExternalStorageDirectory(), "MyFolder");

    File imgFile = new File(dir, "Image.png");

    Intent sendIntent = new Intent(Intent.ACTION_VIEW);
    sendIntent.setType("image/*");
    sendIntent.setAction(Intent.ACTION_SEND);
    sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + imgFile));
    sendIntent.putExtra(Intent.EXTRA_TEXT, "<---MY TEXT--->.");
    sendIntent.setPackage("com.facebook.orca");
    sendIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    try {
        startActivity(Intent.createChooser(sendIntent, "Share images..."));
    } catch (android.content.ActivityNotFoundException ex) {
        Toast.makeText(SaveAndShareActivity.this, "Please Install Facebook Messenger", Toast.LENGTH_LONG).show();
    }

Without using Facebook sdk we can't share the image and text simultaneously on facebook. To solve this problem I had create a bitmap of image and text, Share that bitmap on facebook and it's working perfectly.

如果不使用 Facebook sdk，我们就无法在 facebook 上同时共享图像和文本。为了解决这个问题，我创建了一个图像和文本的位图，在 facebook 上共享该位图，它运行良好。
