Question

我正在创建一个应用程序，现在将使用您对几个问题的回答创建一封包含恶意消息的电子邮件。我想知道如何添加一个功能，让我拍照然后通过电子邮件发送给那个人，我相信我有一些设置正确，但我不知道如何通过电子邮件发送。我的代码如下。我还可以提供我尚未添加的任何其他信息

    Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);

    emailIntent.setType("plain/text");
    emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, message);
    startActivity(emailIntent);

        bmp = (Bitmap) extras.get("data");

这将显示可用于发送电子邮件的电子邮件客户端列表。您可以通过启动Intent来让Android为您处理邮件：

final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE); //allow multiple attachments

emailIntent.setType("plain/text"); //limits how Android handles the "send" request to email rather than Facebook, Peep, etc.
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, getText(R.string.subject)); //set the email subject line

ArrayList<Uri> uris = new ArrayList<Uri>(); //multiple attachments must be added via list object
File root = Environment.getExternalStorageDirectory(); //root filepath

//get images to add to email
File fileIn = new File(root, "image.png");
Uri u = Uri.fromFile(fileIn);
uris.add(u);

//get another image to add to email
fileIn = new File(root, "image2.jpg");
u = Uri.fromFile(fileIn);
uris.add(u);
//add images to email
emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);

AdminActivity.this.startActivity(Intent.createChooser(emailIntent, "Send mail..."));

您还可以查看Android camera intent以了解如何启动相机意图并对其返回的图像执行某些操作。
