团队冲刺第二阶段10

今天做了最后分享的功能，组员之间整合了代码，测试各部分的功能实现。

  public void shareNote (Note note) {

    String titleText = note.getTitle();

    String contentText = titleText
        + System.getProperty("line.separator")
        + note.getContent();

    Intent shareIntent = new Intent();
    // Prepare sharing intent with only text
    if (note.getAttachmentsList().isEmpty()) {
      shareIntent.setAction(Intent.ACTION_SEND);
      shareIntent.setType("text/plain");

      // Intent with single image attachment
    } else if (note.getAttachmentsList().size() == 1) {
      shareIntent.setAction(Intent.ACTION_SEND);
      Attachment attachment = note.getAttachmentsList().get(0);
      shareIntent.setType(attachment.getMime_type());
      shareIntent.putExtra(Intent.EXTRA_STREAM, FileProviderHelper.getShareableUri(attachment));

      // Intent with multiple images
    } else if (note.getAttachmentsList().size() > 1) {
      shareIntent.setAction(Intent.ACTION_SEND_MULTIPLE);
      ArrayList<Uri> uris = new ArrayList<>();
      // A check to decide the mime type of attachments to share is done here
      HashMap<String, Boolean> mimeTypes = new HashMap<>();
      for (Attachment attachment : note.getAttachmentsList()) {
        uris.add(FileProviderHelper.getShareableUri(attachment));
        mimeTypes.put(attachment.getMime_type(), true);
      }
      // If many mime types are present a general type is assigned to intent
      if (mimeTypes.size() > 1) {
        shareIntent.setType("*/*");
      } else {
        shareIntent.setType((String) mimeTypes.keySet().toArray()[0]);
      }

      shareIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
    }
    shareIntent.putExtra(Intent.EXTRA_SUBJECT, titleText);
    shareIntent.putExtra(Intent.EXTRA_TEXT, contentText);

    startActivity(Intent.createChooser(shareIntent, getResources().getString(R.string.share_message_chooser)));
  }
