如何在电子邮件正文中显示图像？

Question

注意：我不想将图像附加到电子邮件中

我想在电子邮件正文中显示图片，

我曾尝试过HTML图像标记<img src=\\"http://url/to/the/image.jpg\\">"我得到了输出，你可以在我的问题中看到如何在电子邮件中添加图像身体 ，所以我累了Html.ImageGetter 。

它对我不起作用，它也给了我相同的输出，所以我怀疑是否可以这样做，

我的代码

Intent i = new Intent(Intent.ACTION_SEND);
i.putExtra(Intent.EXTRA_EMAIL,new String[] {"abc@gmail.com"}); 
i.putExtra(Intent.EXTRA_TEXT,
    Html.fromHtml("Hi <img src='http://url/to/the/image.jpg'>",
    imgGetter,
    null));

i.setType("image/png");
startActivity(Intent.createChooser(i,"Email:"));


private ImageGetter imgGetter = new ImageGetter() {

    public Drawable getDrawable(String source) {
        Drawable drawable = null;
            try {
                drawable = getResources().getDrawable(R.drawable.icon);
                drawable.setBounds(0, 0, drawable.getIntrinsicWidth(),
                    drawable.getIntrinsicHeight());
            } catch (Exception e) {
                e.printStackTrace();
                Log.d("Exception thrown",e.getMessage());
            } 
            return drawable;
    }
};

更新1：如果我使用TextView的ImageGetter代码我能够获取文本和图像，但我无法在电子邮件正文中看到图像

这是我的代码：

TextView t = null;
t = (TextView)findViewById(R.id.textviewdemo);
t.setText(Html.fromHtml("Hi <img src='http://url/to/the/image.jpg'>",
    imgGetter,
    null));

更新2：我使用了粗体标签和锚标签，因为我在下面显示这些标签工作正常，但是当我使用img标签时，我能够看到一个方形框，表示为OBJ

 i.putExtra(Intent.EXTRA_TEXT,Html.fromHtml("<b>Hi</b><a href='http://www.google.com/'>Link</a> <img src='http://url/to/the/image.jpg'>",
        imgGetter,
        null));

Answer 1

不幸的是，使用Intents不可能做到这一点。

为什么例如粗体文本显示在EditText上，而不是一个形象的原因是StyleSplan正在实施Parcelable而ImageSpan没有。 因此，当在新的Activity中检索到Intent.EXTRA_TEXT时，ImageSpan将无法取消选中，因此不会成为附加到EditText的样式的一部分。

遗憾的是，使用其他方法不使用Intent传递数据，因为您无法控制接收活动。

我知道这不能回答原来的问题，但对于某些人来说可能是一个可接受的选择，而是将图像附加到电子邮件中。 我设法通过以下代码实现了这一目标......

String urlOfImageToDownload = "https://ssl.gstatic.com/s2/oz/images/google-logo-plus-0fbe8f0119f4a902429a5991af5db563.png";

// Start to build up the email intent
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("message/rfc822");
i.putExtra(Intent.EXTRA_EMAIL, new String[] { "abc@mail.com" });
i.putExtra(Intent.EXTRA_SUBJECT, "Check Out This Image");
i.putExtra(Intent.EXTRA_TEXT, "There should be an image attached");

// Do we need to download and attach an icon and is the SD Card available?
if (urlOfImageToDownload != null && Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())) {
    // Download the icon...
    URL iconUrl = new URL(urlOfImageToDownload);
    HttpURLConnection connection = (HttpURLConnection) iconUrl.openConnection();
    connection.setDoInput(true);
    connection.connect();
    InputStream input = connection.getInputStream();
    Bitmap immutableBpm = BitmapFactory.decodeStream(input);

    // Save the downloaded icon to the pictures folder on the SD Card
    File directory = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
    directory.mkdirs(); // Make sure the Pictures directory exists.
    File destinationFile = new File(directory, attachmentFileName);
    FileOutputStream out = new FileOutputStream(destinationFile);
    immutableBpm.compress(Bitmap.CompressFormat.PNG, 90, out);
    out.flush();
    out.close();
    Uri mediaStoreImageUri = Uri.fromFile(destinationFile);     

    // Add the attachment to the intent
    i.putExtra(Intent.EXTRA_STREAM, mediaStoreImageUri);
}                       

// Fire the intent
startActivity(i);

两个简单的建议：

• 关闭你的img标签（ <img src="..." />而不是<img src="..."> ）
• 使用i.setType("text/html")代替i.setType("image/png")

如果这些都不起作用，也许您尝试将图像附加到电子邮件，然后使用"cid:ATTACHED_IMAGE_CONTENT_ID" "http:URL_TO_IMAGE"而不是"http:URL_TO_IMAGE"来引用它？

Intent i = new Intent(Intent.ACTION_SEND);
i.putExtra(Intent.EXTRA_EMAIL,new String[] {"abc@gmail.com"}); 
i.putExtra(Intent.EXTRA_STREAM, Uri.parse("http://url/to/the/image.jpg");
i.putExtra(Intent.EXTRA_TEXT,
        Html.fromHtml("Hi <img src='cid:image.jpg' />", //completely guessing on 'image.jpg' here
        imgGetter,
        null));
i.setType("image/png");

请参阅apache电子邮件用户指南中标题为发送带有嵌入式图像的HTML格式电子邮件的部分

虽然，那么你需要知道附加图像的内容id，我不确定是否通过标准的Intent方法浮出水面。 也许您可以检查原始电子邮件并确定其命名约定？
