注意：我不想将图片附加到电子邮件

我想在电子邮件正文中显示图片，

我曾尝试使用HTML图片代码<img src=\"http://url/to/the/image.jpg\">"，我在How to add an image in email body的问题中看到了输出，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ImageGetter TextView代码，我可以获取文字和图片，但我无法在电子邮件中看到该图片体

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，表示为OBJ < / p>

 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无法做到这一点。

例如粗体文本在EditText而不是图片中显示的原因是StyleSplan正在实施Parcelable，而ImageSpan则没有。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。

由于您无法控制接收活动，因此遗憾的是，您无法使用其他方法在此处使用Intent传递数据。

Answer 2

首先提出两个简单的建议：

关闭您的img标记（<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，也许您尝试将图片附加到电子邮件中，然后使用"cid:ATTACHED_IMAGE_CONTENT_ID"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 email user guide

中标题为发送带有嵌入图片的HTML格式电子邮件的部分

但是，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？

我知道这不能回答原来的问题但是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);
