自定义Android Intent.ACTION_SEND

androidfacebookandroid-intent
30

我正在使用Intent来共享网址和主题。在这个Intent过滤器中，显示了所有的共享应用程序。我只想在弹出窗口中显示（Facebook/Gmail/信息/Skype/Twitter）这些选项。是否可以自定义共享Intent过滤器。

 Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
 sharingIntent.setType("text/plain");
 String shareBody = adapter.getDetails("url";
 sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"subject");
 sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
 startActivity(Intent.createChooser(sharingIntent, "Share via"));

谢谢

是的，它是可能的。查看下面的内容，其中显示了Facebook、Gmail、Twitter的过滤。

更新分享文字+图片：

从SD卡中选择图像：

String fileName = "image-3116.jpg";
String externalStorageDirectory = Environment.getExternalStorageDirectory().toString();
String myDir = externalStorageDirectory + "/saved_images/"; // the
            // file will be in saved_images
Uri uri = Uri.parse("file:///" + myDir + fileName);

   shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, (String) v.getTag(R.drawable.ic_launcher));

Facebook不再接受额外参数（EXTRA_PARAMETERS）。https://developers.facebook.com/x/bugs/332619626816423/ - culebrins

好的解决方案！只需改进一些细节。我仅在Twitter上实现了它，所以我只会介绍有关Twitter分享的内容。首先，您需要提供列表类型：List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0);，其次 - Twitter的活动名称可能不完全是 com.twitter.android.PostActivity，因此使用此名称进行检查是有风险的，最好这样做：if (app.activityInfo.name.contains("twitter")) {.....} - Andranik

如果用户安装了Facebook应用和Facebook Messenger应用，此方法可能无法正常运行，因为它可能会选择错误的应用程序。 - Greg Ennis

@GregEnnis "v.getTag" 是什么意思？它是指哪个对象？ - Hardik Parmar

@Ankur1994a 这也可以运作，因为Facebook可能已经更改了其包名。 - GrIsHu

单一方法实现多种功能

share(String nameApp, String imagePath, String message) 函数的代码：

public void share(String nameApp, String imagePath, String message) {
    try {
        List<Intent> targetedShareIntents = new ArrayList<Intent>();
        Intent share = new Intent(android.content.Intent.ACTION_SEND);
        share.setType("image/jpeg");
        List<ResolveInfo> resInfo = getPackageManager()
                .queryIntentActivities(share, 0);
        if (!resInfo.isEmpty()) {
            for (ResolveInfo info : resInfo) {
                Intent targetedShare = new Intent(
                        android.content.Intent.ACTION_SEND);
                targetedShare.setType("image/jpeg"); // put here your mime
                                                        // type
                if (info.activityInfo.packageName.toLowerCase().contains(
                        nameApp)
                        || info.activityInfo.name.toLowerCase().contains(
                                nameApp)) {
                    targetedShare.putExtra(Intent.EXTRA_SUBJECT,
                            "Sample Photo");
                    targetedShare.putExtra(Intent.EXTRA_TEXT, message);
                    targetedShare.putExtra(Intent.EXTRA_STREAM,
                            Uri.fromFile(new File(imagePath)));
                    targetedShare.setPackage(info.activityInfo.packageName);
                    targetedShareIntents.add(targetedShare);
                }
            }
            Intent chooserIntent = Intent.createChooser(
                    targetedShareIntents.remove(0), "Select app to share");
            chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS,
                    targetedShareIntents.toArray(new Parcelable[] {}));
            startActivity(chooserIntent);
        }
    } catch (Exception e) {
        Log.v("VM",
                "Exception while sending image on" + nameApp + " "
                        + e.getMessage());
    }
}

使用以下代码在 Gmail、Facebook 和 Twitter 上附加带有文本的图像。

File filePath = new File("your image path");
share("gmail", filePath.toString(),"your comment");
share("facebook", filePath.toString(),"your comment");
share("twitter", filePath.toString(),"your comment");
可以使用相同的代码在Google+和LinkedIn上分享吗？如果不行，需要做哪些更改？ - Anitha

上述答案打开了我的手机上的Facebook聊天应用程序。以下操作成功了！
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
                sharingIntent.setType("text/plain");
                sharingIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
                sharingIntent.putExtra(Intent.EXTRA_TEXT, "Text...");
                PackageManager packManager = getPackageManager();
                List<ResolveInfo> resolvedInfoList = packManager.queryIntentActivities(sharingIntent,  PackageManager.MATCH_DEFAULT_ONLY);

                boolean resolved = false;
                for(ResolveInfo resolveInfo: resolvedInfoList){
                    if(resolveInfo.activityInfo.packageName.startsWith("com.facebook.katana")){
                        sharingIntent.setClassName(
                            resolveInfo.activityInfo.packageName, 
                            resolveInfo.activityInfo.name );
                        resolved = true;
                        break;
                    }
                }
                if(resolved){
                    startActivity(sharingIntent);
                }else{

                     Builder alert  = new AlertDialog.Builder(ActivityName.this);
                        alert.setTitle("Warning");
                        alert.setMessage("Facebook App not found");
                        alert.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,int which) 
                            {
                                dialog.dismiss();

                            }
                        });
                        alert.show();
                }
+1 分享！但我无法发送任何文本/图像....我知道这是一个错误...但是否真的有任何解决方法，而不使用 Facebook SDK？ - denvercoder9
