自定义Android Intent.ACTION_SEND

Question

我正在使用Intent来共享网址和主题.在此意图过滤器中显示所有共享应用程序.我只想要(facebook/gmail/message/skype/twitter)弹出窗口中的这些选项.这可以自定义共享意图过滤器.

 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

Answer 1

是的,它可能在下面查看显示Facebook,Gmail,Twitter的过滤.

已更新为共享文字+图片:

从SDCard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);

多功能的单一方法

share(String nameApp,String imagePath,String message)功能代码:

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());
    }
}

用于在gmail,facebook,twitter上附加图像,文本使用下面的代码.

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");
