使用Asset文件夹中的附件发送电子邮件

Question

    //EMAIL SENDING CODE  FROM ASSET FOLDER
    email = editTextEmail.getText().toString();
    subject = editTextSubject.getText().toString();
    message = editTextMessage.getText().toString();
    final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
    emailIntent.setType("file/html");
    emailIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("content://com.example.deepa.xmlparsing/file:///android_assets/Combination-1.html"));
    startActivity(Intent.createChooser(emailIntent, "Send email using"));

最后,我从资产文件夹(Combination-1.html)获取文件.

它越来越好了

找不到运行时错误文件异常.

有没有其他方式发送文件附件？

Answer 1

发送电子邮件的最简单方法是创建ACTION_SEND类型的Intent:

Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_SUBJECT, "Test");
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{recipient_address});
intent.putExtra(Intent.EXTRA_TEXT, "Attachment test");

要附加单个文件,请向Intent添加一些扩展数据:

intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File("/path/to/file")));
intent.setType("text/html");

或者使用Html.fromHtml()来构建html内容:

intent.putExtra( Intent.EXTRA_TEXT,
                 Html.fromHtml(new StringBuilder()
                 .append("<h1>Heading 1</h1>")
                 .append("<p><a>http://www.google.com</a></p>")
                 .toString()));

对于多个附件:

Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
intent.setType("text/html");
intent.putExtra(Intent.EXTRA_SUBJECT, "Test multiple");
intent.putExtra(Intent.EXTRA_TEXT, "multiple attachments");
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{recipient_address});
ArrayList<Uri> uris = new ArrayList<Uri>();
uris.add(Uri.fromFile(new File("/path/to/first/file")));
uris.add(Uri.fromFile(new File("/path/to/second/file")));
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);

完成调用startActivity()传递intent.
