Android:如何通过意图在Facebook上与文本共享图像？

Question

我想通过Facebook上的分享意图与我的应用程序预先填充的标题分享照片.

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);

这是我得到的屏幕截图

如果设置类型为图像/*,则上传照片时不会预填充文本.如果设置为文本/普通照片不显示.....

最新的Facebook版本不允许您使用意图共享文本.你必须使用Facebook SDK才能做到这一点 - 使用Facebook SDK + Android Simple Facebook(https://github.com/sromku/android-simple-facebook).使用该库,您的代码将是这样的(从Simple Facebook站点中提取):

发布Feed

设置OnPublishListener并致电:

• publish(Feed, OnPublishListener) 没有对话.
• publish(Feed, true, OnPublishListener) 用对话框.

基本属性

• message - 用户的消息
• name - 链接附件的名称
• caption - 链接标题(显示在链接名称下方)
• description - 链接描述(显示在链接标题下方)
• picture - 此帖子附带的图片的网址.图片必须至少为200px×200px
• link - 此帖子附带的链接

初始化回调侦听器:

OnPublishListener onPublishListener = new OnPublishListener() {
    @Override
        public void onComplete(String postId) {
            Log.i(TAG, "Published successfully. The new post id = " + postId);
        }

     /* 
      * You can override other methods here: 
      * onThinking(), onFail(String reason), onException(Throwable throwable)
      */
};

建立Feed:

Feed feed = new Feed.Builder()
    .setMessage("Clone it out...")
    .setName("Simple Facebook for Android")
    .setCaption("Code less, do the same.")
    .setDescription("The Simple Facebook library project makes the life much easier by coding less code for being able to login, publish feeds and open graph stories, invite friends and more.")
    .setPicture("https://raw.github.com/sromku/android-simple-facebook/master/Refs/android_facebook_sdk_logo.png")
    .setLink("https://github.com/sromku/android-simple-facebook")
    .build();

不带对话框发布Feed :

mSimpleFacebook.publish(feed, onPublishListener);

使用对话框发布Feed :

mSimpleFacebook.publish(feed, true, onPublishListener);

根据新的Facebook SDK.

Facebook的Android的SDK:4.6.0

这很简单.
1.创建提供者Android.manifest.xml

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

2.使用数据创建您的共享意图.

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.显示"共享"对话框

ShareDialog.show(ShowNavigationActivity.this,shareLinkContent);

而已.

试试这个

private void initShareIntent(String type,String _text){
     File filePath = getFileStreamPath("shareimage.jpg");  //optional //internal storage
     Intent shareIntent = new Intent();
     shareIntent.setAction(Intent.ACTION_SEND);
     shareIntent.putExtra(Intent.EXTRA_TEXT, _text);
     shareIntent.putExtra(Intent.EXTRA_STREAM,Uri.fromFile(new File(filePath)));  //optional//use this when you want to send an image
     shareIntent.setType("image/jpeg");
     shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
     startActivity(Intent.createChooser(shareIntent, "send"));
}
