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); } } 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://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); } }
