Android通讯录模糊匹配搜索实现（号码、首字母、简拼、全拼）
Android通讯录模糊匹配搜索实现（号码、首字母、简拼、全拼）
2013年12月10日 工作记录
小巫在工作中碰到一个需求，要求实现通讯录联系人的搜索，获取联系人的方式有好几种，我都有点混乱了，下面提供我最近用的一种，看起来还算比较简洁的，它是根据mimetypes表来查的。
// 查询所有联系人的姓名，电话，邮箱
public ArrayList loadContacts() throws Exception {
Uri uri = Uri.parse("content://com.android.contacts/contacts");
ContentResolver resolver = this.getContentResolver();
Cursor cursor = resolver.query(uri, new String[] { "_id" }, null, null,
null);
ArrayList contacts = new ArrayList();
while (cursor.moveToNext()) {
Contact contact = new Contact();
int contractID = cursor.getInt(0);
StringBuilder sb = new StringBuilder("contractID=");
contact.setId(String.valueOf(contractID));
sb.append(contractID);
uri = Uri.parse("content://com.android.contacts/contacts/"
+ contractID + "/data");
Cursor cursor1 = resolver.query(uri, new String[] { "mimetype",
"data1", "data2" }, null, null, null);
while (cursor1.moveToNext()) {
String data1 = cursor1.getString(cursor1
.getColumnIndex("data1"));
String mimeType = cursor1.getString(cursor1
.getColumnIndex("mimetype"));
if ("vnd.android.cursor.item/name".equals(mimeType)) { // 是姓名
contact.setName(data1);
sb.append(",name=" + data1);
} else if ("vnd.android.cursor.item/email_v2".equals(mimeType)) { // 邮箱
if (!TextUtils.isEmpty(data1)) {
contact.setEmail(data1);
}
contacts.add(contact);
sb.append(",email=" + data1);
} else if ("vnd.android.cursor.item/phone_v2".equals(mimeType)) { // 手机
contact.setNumber(data1.replaceAll("-", ""));
sb.append(",phone=" + data1);
}
}
contacts.add(contact);
cursor1.close();
Log.i("wwj", sb.toString());
}
cursor.close();
return contacts;
}
关于模糊匹配，我真的有点头大，我想到的是用正则表达式来做，但需要用到第三方类库pinyin4j.jar，我试了一下，效率都点低，明显感觉有点慢了，假如你的通讯录的量比较大，用这个来做确实不合时宜，或许可以进行优化的地方。
定义一个工具类

上面的代码是我从网上搜了很久才搜到的一个demo里面的代码，我整合到项目当中去，发现使用pinyin4j.jar类库效率实在有点低，所以我自己想了其他办法，不用第三方类库来实现。
下面是小巫的实现：

}不过我也发现了一问题，关于一个中文字符的字节数的问题，不同的编码可能会存在中文的字节数不同的情况，比如GBK编码的中文是2，而UTF-8的编码是3。其实我发现这个问题也挺惊奇的，这个问题可能是我们以后编码的时候会遇到的，一个编码就可能把你搞死。
英文字母和中文汉字在不同字符集编码下的字节数
英文字母：
字节数 : 1;编码：GB2312
字节数 : 1;编码：GBK
字节数 : 1;编码：GB18030
字节数 : 1;编码：ISO-8859-1
字节数 : 1;编码：UTF-8
字节数 : 4;编码：UTF-16
字节数 : 2;编码：UTF-16BE
字节数 : 2;编码：UTF-16LE
中文汉字：
字节数 : 2;编码：GB2312
字节数 : 2;编码：GBK
字节数 : 2;编码：GB18030
