这是我的代码

QObject::connect(&model, SIGNAL(itemChanged(QStandardItem*)),
    &myObject, SLOT(onItemChanged(QStandardItem*)));

但是当我收到的电子邮件没有格式时，我必须选择一个程序来打开它best source

Answer 1

使用我的代码

      File image = new File(Uri.parse("android.resource://" + C.PROJECT_PATH + "/drawable/" + R.drawable.icon_to_share).toString());
      email.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(image));

喜欢

       Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
        emailIntent.setType("application/image");
        emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{strEmail}); 
        emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Test Subject"); 
        emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "From My App"); 

    File image = new File(Uri.parse("android.resource://" + C.PROJECT_PATH + "/drawable/" + R.drawable.icon_to_share).toString());

       emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(image));
        startActivity(Intent.createChooser(emailIntent, "Send mail..."));

Answer 2

您可以看到此answer。

首先，你需要在drawable文件夹中获取图像

imageName = "planet";
int resourceImage = getActivity().getResources().getIdentifier(imageName, getPackageName());

必须将可绘制资源保存在SDCard等内部存储中。

 try {
            Bitmap bitmap = BitmapFactory.decodeResource(getResources(), resourceImage);
            ByteArrayOutputStream bytes = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.PNG, 50, bytes);
            File file = new File(Environment.getExternalStorageDirectory() + File.separator + "temporal.png");

            boolean isCreated = file.createNewFile();

            FileOutputStream fileOutputStream = new FileOutputStream(file);
            fileOutputStream.write(bytes.toByteArray());
            fileOutputStream.close();

        } catch (IOException e) {

        }

最后通过电子邮件发送图片你必须使用sharedintent：

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("image/png");
shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "this is a subject"); //set your subject
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "this is the message"); //set your message

String imagePath = Environment.getExternalStorageDirectory() +File.separator +"temporal.png";
File imageFileToShare = new File(imagePath);
Uri uri = Uri.fromFile(imageFileToShare);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(shareIntent, "Share image"));
