意向共享无法附加图像

Question

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "My text");
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(http://onman.ir/colorfinder/sample.jpg));
sendIntent.setType("*/*");
sendIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(Intent.createChooser(sendIntent, "Share using"));

此代码在与Gmail共享意图时无法附加图像，在与仅共享多个图像或视频的Facebook共享时也会出错。当我用sendIntent.setType("image/*")更改类型时，它会打开Facebook的共享窗口，但文本和图像为空白。

Answer 1

对于共享，您可以使用此代码

     Intent shareIntent = new Intent();
                   shareIntent.setAction(Intent.ACTION_SEND);
                   shareIntent.setType("image/*");
                   shareIntent.putExtra(Intent.EXTRA_TEXT,"abc");
                   shareIntent.putExtra(Intent.EXTRA_STREAM, imagebitmap);
                  startActivity(Intent.createChooser(shareIntent, "Share using"));

但是如果你想在Facebook上做，它将无法通过意图工作，你应该使用Facebook SDK来分享图像和文本。

FacebookDialog shareDialog = new FacebookDialog.ShareDialogBuilder(this)
                                   .setLink(url)
                                   .setCaption(getString(R.string.fb_share))
                                   .setDescription(getString(R.string.fb_share))
                                   .setPicture(
                                                 "https://scontent-lhr3-1.xx.fbcdn.net/hphotos-xfp1/v/t1.0-9/11899955_1616850925232395_9146772907853639083_n.jpg?oh=3dd7da7bf03edee84689d66af2024880&oe=56793D62")
                                   .build();
                     uiHelper.trackPendingDialogCall(shareDialog.present());
                     dismissProgressBar();

在您的代码中，您首先直接共享图像URL，您需要获取位图，然后共享位图而不是URL

Answer 2

private void shareImage(( { 意向份额 = 新意向 (Intent.ACTION_SEND(;

// If you want to share a png image only, you can do:
// setType("image/png"); OR for jpeg: setType("image/jpeg");
share.setType("image/*");
// Make sure you put example png image named myImage.png in your
// directory
String imagePath = Environment.getExternalStorageDirectory()
        + "/myImage.png";
File imageFileToShare = new File(imagePath);
Uri uri = Uri.fromFile(imageFileToShare);
share.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(share, "Share Image!"));

试试这个代码

请注意，当您使用 setType(( 方法时，您将启用 Android 来过滤哪些应用程序可以共享您的内容。例如，您正在共享文本或URL，要显示的相应应用程序可以是Facebook，消息或电子邮件。如果您正在共享图像，合适的应用程序可以是Instagram，Ssnapped或Picasa。

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == UPLOADIMAGE && resultCode == RESULT_OK)
    {
        uploadImage.setVisibility(View.GONE);
        imageView.setVisibility(View.VISIBLE);
        if (data !=null)
        {
            imageUri=data.getData();
            imageView.setImageURI(imageUri);
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };
            Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
            cursor.moveToFirst();
            columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            attachmentFile = cursor.getString(columnIndex);
            Log.e("Attachment Path:", attachmentFile);
            URI = Uri.parse("file://" + attachmentFile);
            cursor.close();
        }
        else {Toast.makeText(TutorForm.this,"Uploading image failed",Toast.LENGTH_LONG).show();}


    }
    super.onActivityResult(requestCode, resultCode, data);

OnClickListner

 Intent emailIntent=new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:"+ clientEmail));
        emailIntent.putExtra(Intent.EXTRA_TEXT,body);
        emailIntent.putExtra(Intent.EXTRA_SUBJECT,"Tutor Registration from App");
        emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        Uri uri = Uri.parse(imageUri.toString());
        emailIntent.putExtra(Intent.EXTRA_STREAM,URI);
        startActivity(Intent.createChooser(emailIntent,"Send Via..."));

Answer 4

shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
shareIntent.setType("image/*");
//set your message
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, msgText); 
String imagePath = Environment.getExternalStorageDirectory() + 
File.separator + "image_name.jpg";
File imageFileToShare = new File(imagePath);
Uri uri = Uri.fromFile(imageFileToShare);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
Uri uri = Uri.fromFile(imageFileToShare);
sharingIntent.putExtra(Intent.EXTRA_STREAM, uri);

Answer 5

这个对我有用

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
            shareIntent.setType("image/jpeg");
            shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, getResources().getString(R.string.share_subject));
            shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, getResources().getString(R.string.share_message));
            shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(yourimagepath);
            startActivity(Intent.createChooser(shareIntent, "Share Image"));
