ContactsProvider2.java 中的queryLocal函数，修改方法如下：
case CALLABLES_FILTER:
......
if (searchPhoneNumber) {
......
sb.append(Data._ID +
" IN (SELECT DISTINCT " + PhoneLookupColumns.DATA_ID
+ " FROM " + Tables.PHONE_LOOKUP
+ " WHERE " + PhoneLookupColumns.NORMALIZED_NUMBER + " LIKE ‘");
//add here
sb.append("%");
sb.append(number);
sb.append("%‘)");
hasCondition = true;
}android短信选择收件人时，号码搜索联系人修改成任意位置开始中间匹配
