Question

我一直在开发Android程序，使用Intent和Intent.ACTION_SEND使用Intent.putParcelableArrayListExtra(android.content.Intent.EXTRA_STREAM, uri)发送带有附件（text / plain）的电子邮件我使用Intent.putExtra(android.content.Intent.EXTRA_STREAM, uri)但是，当我尝试拥有多个文件时通过多次调用final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); System.out.println(emailText+emailTo); emailIntent.setType("text/plain"); emailIntent.putExtra(android.content.Intent.EXTRA_TEXT,emailText); emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject); emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,new String[]{emailTo}); //has to be an ArrayList ArrayList<Uri> uris = new ArrayList<Uri>(); //convert from paths to Android friendly Parcelable Uri's try { for (String file : filePaths) { File fileIn = new File(context.getFilesDir(),file); System.out.println(fileIn+"yes"); Uri u = Uri.fromFile(fileIn); uris.add(u); System.out.println(u); } emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM,uris); context.startActivity(Intent.createChooser(emailIntent, "Send mail...")); }附加到同一邮件，它无法正常工作。没有任何附件出现在电子邮件中。谢谢提前

Answer 1

使用ACTION_SEND_MUTIPLE代替ACTION_SEND

http://developer.android.com/reference/android/content/Intent.html#ACTION_SEND_MULTIPLE

final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE);

Answer 2

确保第二个参数 file 仅提供有效的文件名。你的问题可能就在那里......

File fileIn = new File(context.getFilesDir(),file);

以下代码无任何问题。

Intent emailIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
//...
ArrayList<Uri> uris = new ArrayList<Uri>();
uris.add(Uri.parse("file://" + Environment.getExternalStorageDirectory().getPath() + "/HOME/Pictures/1.png"));
uris.add(Uri.parse("file://" + Environment.getExternalStorageDirectory().getPath() + "/HOME/Pictures/2.png"));
uris.add(Uri.parse("file://" + Environment.getExternalStorageDirectory().getPath() + "/HOME/Pictures/3.png"));
uris.add(Uri.parse("file://" + Environment.getExternalStorageDirectory().getPath() + "/HOME/Pictures/4.png"));
emailIntent.putParcelableArrayListExtra(android.content.Intent.EXTRA_STREAM, uris);
startActivity(emailIntent);

意图中的附件问题
