This example describes how Android gets the avatar of a contact. Share to everyone for your reference, specific as follows:

Public byte[] Getphoto (string people_id) {
string photo_id = null;
String Selection1 = contactscontract.contacts._id + "=" + people_id;
Cursor cur1 = Getcontentresolver (). Query (
ContactsContract.Contacts.CONTENT_URI, NULL, selection1, NULL, NULL);
if (Cur1.getcount () > 0)
cur1.movetofirst ();
photo_id = cur1.getstring (Cur1.getcolumnindex (ContactsContract.Contacts.PHOTO_ID));
System.out.println ("photo_id:" + photo_id);
string[] projection = new string[]
String selection = + "=" + photo_id;
Cursor cur = getcontentresolver (). Query (
ContactsContract.Data.CONTENT_URI, projection, selection, NULL, NULL); C18/>cur.movetofirst ();
byte[] Contacticon = Cur.getblob (0);
System.out.println ("Contacticon:" + Contacticon);
if (Contacticon = = null) {return
} else {return

The following code converts a byte array into a Bitmap object and then displays it in ImageView

Private ImageView image;
byte[] photo = Getphoto (ContactID);
Bitmap map = Bitmapfactory.decodebytearray (photo, 0,photo.length);
Image.setimagebitmap (map);

To set up an Android contact's avatar by code:

Private Final Static Boolean oldsdk = (System.getsdkversionnumber () < 5)?
True:false;  public static void Setpersonphotobytes (context context,byte[] B, Long Persionid, Boolean Sync) {if (OLDSDK) {Uri MyPerson
= Contenturis.withappendedid (People.content_uri, Persionid);
People.setphotodata (Context.getcontentresolver (), MyPerson, b); if (! Sync) {contentvalues values = new Contentvalues (); Values.put ("_sync_dirty", 0); Context.getcontentresolver (). Update (
MyPerson, values, NULL, NULL);
} else SetContactPhoto5 (Context.getcontentresolver (), B, Persionid, Sync);  } private static void SetContactPhoto5 (Contentresolver C, byte[] Bytes,long personId, Boolean Sync) {contentvalues values
= new Contentvalues ();
Uri u = uri.parse ("Content://");
int photorow =-1;
String where = "raw_contact_id =" + PersonId + "and mimetype = ' '";
Cursor Cursor = c.query (U, NULL, where, NULL, NULL);
int ididx = Cursor.getcolumnindexorthrow ("_id"); if (curSor.movetofirst ()) {Photorow = Cursor.getint (IDIDX);} cursor.close ();
Values.put ("raw_contact_id", personId);
Values.put ("Is_super_primary", 1);
Values.put ("Data15", bytes);
Values.put ("MimeType", ""); if (photorow >= 0) {c.update (U, Values, "_id=" + photorow, null);} else {C.insert (U, values);} if (! Sync) {u = Uri.withappendedpath (Uri.parse ("Content://"), String.valueof (personId)
values = new Contentvalues ();
Values.put ("dirty", 0);
C.update (U, values, NULL, NULL);
