android 加载本地联系人实现方法

概述首先先建布局文件，界面很简单，就是一个搜索框和下面的联系人列表： 复制代码代码如下:<?xmlversion=\"1.0\"encoding=\"utf-8\"?><LinearLayoutxmlns:android=\"http://schemas.android.com/apk/res/ 首先先建布局文件，界面很简单，就是一个搜索框和下面的联系人列表：

 

复制代码 代码如下:
<?xml version="1.0" enCoding="utf-8"?>

然后是点击事件：(点击后要把选择的联系人号码返回到输入框里)

 

复制代码 代码如下:
// 获取联系人按钮对象并绑定onClick单击事件
phonebutton = (button) findVIEwByID(R.ID.find_phone);
phonebutton.setonClickListener(new OnClickListener() {
public voID onClick(VIEw v) {
// 从联系人选择号码，再通过onActivityResult()方法处理回调结果
Intent intent = new Intent(context,ContactsActivity.class);
startActivityForResult(intent,REQUEST_CODE);
}
});
/**
* 选择联系人的回调处理函数
*/
@OverrIDe
public voID onActivityResult(int reqCode,int resultCode,Intent data) {
super.onActivityResult(reqCode,resultCode,data);
if (resultCode == RESulT_OK) {
switch (reqCode) {
case REQUEST_CODE:
String phone = data.getStringExtra("phone");
phoneEditText.setText(phone);
break;
}
}
}

 

下面就是联系人界面的activity了：
复制代码 代码如下:

查询方法语句：
复制代码 代码如下:
/**
* 根据条件查询联系人数据
*
* @param context 上下文环境
* @param keyWord 查询关键字
* @return List<HashMap<String,String>>
*/
public static List<HashMap<String,String>> findContactsByCond(Context context,String keyWord) {
List<HashMap<String,String>>();
sqliteDatabase db = DBHelper.getsqliteDb(context);
String sql = "select * from contacts where name like '" + keyWord + "%' or name_alias like '" + keyWord + "%' order by _ID";
// 查询数据
Cursor cursor = db.rawquery(sql,null);
while (cursor.movetoNext()) {
HashMap<String,String> map = new HashMap<String,String>();
map.put("name",cursor.getString(cursor.getColumnIndex("name")));
map.put("phone",cursor.getString(cursor.getColumnIndex("phone")));
map.put("type",cursor.getString(cursor.getColumnIndex("type")));
map.put("photo",cursor.getString(cursor.getColumnIndex("photo")));
List.add(map);
}
cursor.close();
db.close();
return List;
}
/**
* 存储联系人信息
*
* @param context 上下文环境
* @param contactsList 联系人列表
*/
public static voID saveContacts(Context context,List<HashMap<String,String>> contactsList) {
sqliteDatabase db = DBHelper.getsqliteDb(context);
// 开启事务控制
db.beginTransaction();
try {
// 先将联系人数据清空
db.execsql("drop table if exists contacts");
db.execsql("create table contacts(_ID integer not null primary key autoincrement,name varchar(50),name_alias varchar(10),phone varchar(30),type varchar(50),photo varchar(50))");
String sql = null;
for (HashMap<String,String> contactsMap : contactsList) {
sql = String.format("insert into contacts(name,name_alias,phone,type,photo) values('%s','%s','%s')",contactsMap.get("name"),SaleUtil.getPinYinFirstAlphabet(contactsMap.get("name")),contactsMap.get("phone"),contactsMap.get("type"),contactsMap.get("photo"));
db.execsql(sql);
}
// 设置事务标志为成功
db.setTransactionSuccessful();
} finally {
// 结束事务
db.endTransaction();
db.close();
}
}

工具类：
复制代码 代码如下:
/**
* 判断客户手机号码是否符合规则
*
* @param userPhone 客户手机号码
* @return true | false
*/
public static boolean isValIDPhoneNumber(String userPhone) {
if (null == userPhone || "".equals(userPhone))
return false;
Pattern p = Pattern.compile("^0?1[0-9]{10}");
Matcher m = p.matcher(userPhone);
return m.matches();
}
/**
* 获取中文的拼音首字母
*
* @param chinese 中文
* @return 拼音首字母
*/
public static String getPinYinFirstAlphabet(String chinese) {
String convert = "";
for (int j = 0; j < chinese.length(); j++) {
char word = chinese.charat(j);
String[] pinyinArray = PinyinHelper.toHanyuPinyinStringArray(word);
if (pinyinArray != null) {
convert += pinyinArray[0].charat(0);
} else {
convert += word;
}
}
return convert;
}

最后加上权限就行了;
复制代码 代码如下:
<!-- 访问联系人的权限 -->
<uses-permission androID:name="androID.permission.READ_CONTACTS" />
