Android-更新联系人

最后，我发现了如何更新联系人，这是update方法的代码：

    public void update()    {    int id = 1;        String firstname = "Contact's first name";        String lastname = "Last name";        String number = "000 000 000";        String photo_uri = "android.resource://com.my.package/drawable/default_photo";        ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();        // Name        Builder builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI);        builder.withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND " + ContactsContract.Data.MIMETYPE + "=?", new String[]{String.valueOf(id), ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE});        builder.withValue(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME, lastname);        builder.withValue(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME, firstname);        ops.add(builder.build());        // Number        builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI);        builder.withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND " + ContactsContract.Data.MIMETYPE + "=?"+ " AND " + ContactsContract.CommonDataKinds.Organization.TYPE + "=?", new String[]{String.valueOf(id), ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE, String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_HOME)});        builder.withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, number);        ops.add(builder.build());        // Picture        try        { Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), Uri.parse(photo_uri)); ByteArrayOutputStream image = new ByteArrayOutputStream(); bitmap.compress(Bitmap.CompressFormat.JPEG , 100, image); builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI); builder.withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND " + ContactsContract.Data.MIMETYPE + "=?", new String[]{String.valueOf(id), ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE}); builder.withValue(ContactsContract.CommonDataKinds.Photo.PHOTO, image.toByteArray()); ops.add(builder.build());        }        catch (Exception e)        { e.printStackTrace();        }        // Update        try        { getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);        }        catch (Exception e)        { e.printStackTrace();        }    }

该字段

id

    ContentProviderResult[] res;    try    {        res = KramerApplication.getInstance().getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);        if (res != null && res[0] != null)        { String uri = res[0].uri.getPath().substring(14); r.setBook_id( new Integer(uri).intValue() );        }    }    catch (Exception e)    {        e.printStackTrace();    }
