本文实例讲述了Android获取联系人头像的方法。分享给大家供大家参考，具体如下：
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[]{ContactsContract.Data.DATA15};String selection = ContactsContract.Data._ID + " = " + photo_id;Cursor cur = getContentResolver().query(ContactsContract.Data.CONTENT_URI, projection, selection, null, null);cur.moveToFirst();byte[] contactIcon = cur.getBlob(0);System.out.println("conTactIcon:" + contactIcon);if (contactIcon == null) {return null;} else {return contactIcon;}}
以下代码将字节数组转化成Bitmap对象，然后再ImageView中显示出来
private ImageView image;byte[] photo = getPhoto(contactId);Bitmap map = BitmapFactory.decodeByteArray(photo, 0,photo.length);image.setImageBitmap(map);
通过代码设置Android联系人的头像：
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);}}elsesetContactPhoto5(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://com.android.contacts/data");int photoRow = -1;String where ="raw_contact_id = " + personId + " AND mimetype ='vnd.android.cursor.item/photo'";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","vnd.android.cursor.item/photo");if (photoRow >= 0) {c.update(u, values, " _id= " + photoRow, null);} else {c.insert(u, values);}if (! Sync){u = Uri.withAppendedPath(Uri.parse("content://com.android.contacts/raw_contacts"),String.valueOf(personId));values = new ContentValues();values.put("dirty", 0);c.update(u, values, null, null);}}
