注意：我不想将图像附加到电子邮件

我想在电子邮件正文中显示图像，

我已经尝试过 HTML 图像标记<img src=\"http://url/to/the/image.jpg\">"，并且得到了输出，正如您在我关于如何在电子邮件正文中添加图像的问题中看到的那样，所以我很累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ImageGetter代码，TextView我可以获得文本和图像，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，如下所示，这些标签工作正常，但是当我使用 img 标签时，我可以看到一个方框，上面写着 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));

不幸的是，使用 Intents 是不可能做到这一点的。

例如，在 EditText 而不是 Image 中显示粗体文本的原因是StyleSplan正在实现Parcelable而ImageSpan没有。因此，当在新 Activity 中检索 Intent.EXTRA_TEXT 时，ImageSpan 将无法解包，因此不是附加到 EditText 的样式的一部分。

不幸的是，在这里无法使用其他不通过 Intent 传递数据的方法，因为您无法控制接收活动。

先说两个简单的建议：

  • 关闭您的 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中，然后使用"cid:ATTACHED_IMAGE_CONTENT_ID"而不是"http:URL_TO_IMAGE"?

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“发送带有嵌入图像的HTML 格式电子邮件”的部分

不过，您需要知道附加图像的 content-id，我不确定这是否通过标准 Intent 方法浮出水面。也许您可以检查原始电子邮件并确定它们的命名约定？

我知道这并不能回答最初的问题，但对于某些人来说，一个可以接受的替代方案是将图像附加到电子邮件中。我设法用以下代码实现了这一点......

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);
