You can use the vCard method that is given for Smack 4.1. Load the user's vCard when they are editing their profile information. Then, allow them to upload their avatar. Once they save it, you convert the Bitmap to a byte array, which is then sent to save vCard. Here's an example:
您可以使用为Smack 4.1提供的vCard方法。在用户编辑其个人资料信息时加载用户的vCard。然后,允许他们上传他们的头像。保存后,将Bitmap转换为字节数组,然后发送该数组以保存vCard。这是一个例子:
// Let the user pick their avatar
Bitmap bitmap;
// Take the avatar and convert it into a byte array:
ByteArrayOutputStream stream = new ByteArrayOutputStream();
// 90 refers the the compression quality. For PNG, the quality is ignored
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, stream);
byte[] avatarByte = stream.toByteArray();
// Once you get the byte array from the image, set the byte array to the vCard avatar
vCard.setAvatar(avatarByte);
// Then you can save the vCard details
vCardManager.saveVCard(vCard);
Hope that helps
