如何在電子郵件正文中顯示圖片？

Question

注：我不想圖像附加到電子郵件

我想在電子郵件正文中顯示的圖像，

我曾試圖HTML圖像標記<img src=\"http://url/to/the/image.jpg\">"和我輸出，你可以看到我的問題在How to add an image in email body，所以我累Html.ImageGetter。

它不工作對我來說，這也給了我同樣的輸出，所以我有一個疑問是有可能做到這一點，

我的代碼

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：如果我用的是ImageGetter代碼TextView我能夠得到的文本和圖像，但我無法看到在電子郵件正文

這裏的形象是我的代碼：

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：我用了大膽的標記，錨標記如圖所示，這些標籤下面我工作正常，但是當我使用img標籤，我可以看到一個方形盒子，其稱作爲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，用Intents來做這件事是不可能的。

爲什麼例如大膽文本顯示在EditText上，而不是一個圖像是StyleSplan正在實施Parcelable而ImageSpan沒有原因。因此，當在新Activity中檢索到Intent.EXTRA_TEXT時，ImageSpan將無法刪除，因此不屬於附加到EditText的樣式的一部分。

由於您無法控制接收活動，因此使用其他不使用Intent傳遞數據的方法是不可行的。

兩個簡單的建議，第一：

• 閉上你的img標籤（<img src="..." />而不是<img src="...">）
• 使用i.setType("text/html")代替i.setType("image/png")

如果沒有這些工作，也許你試着將圖像附加到電子郵件，然後用"cid:ATTACHED_IMAGE_CONTENT_ID"引用它，而不是一個"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"); 

見標題爲部分發送HTML格式的電子郵件帶有嵌入式圖像在apache email user guide

雖然，那麼你就需要知道所連接的圖像的內容ID，和我不知道如果這是通過標準的意圖方法浮出水面。也許你可以檢查原始郵件並確定他們的命名約定？

我知道這並不回答原來的問題，但對某些人來說可能是一種可接受的選擇，而不是將圖像附加到電子郵件。我設法用下面的代碼來實現這個...

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);

    you have need three lib of java mail 

    1.activation.jar 
    2.additionnal.jar 
    3.mail.jar
