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"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:background="#FFD3D7DF"

android:orientation="vertical"

android:padding="0dip" >

<RelativeLayout

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:layout_marginLeft="3dip"

android:layout_marginRight="3dip"

android:layout_marginTop="3dip" >

<EditText

android:id="@+id/search_view"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:hint="@string/hint_search_contacts"

android:paddingLeft="32dip"

android:singleLine="true"

android:textSize="16sp" />

<ImageView

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignLeft="@id/search_view"

android:layout_centerVertical="true"

android:layout_marginLeft="3dip"

android:src="@drawable/contacts" />

</RelativeLayout>

<ListView

android:id="@+id/contact_list"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:layout_marginBottom="0dip"

android:layout_marginLeft="0dip"

android:layout_marginRight="0dip"

android:layout_marginTop="0dip"

android:layout_weight="1.0"

android:cacheColorHint="#00000000"

android:divider="#00000000"

android:dividerHeight="0.1px"

android:fadingEdge="none"

android:footerDividersEnabled="false"

android:listSelector="@null"

android:paddingBottom="0dip"

android:paddingLeft="0dip"

android:paddingRight="0dip"

android:paddingTop="0dip" />

</LinearLayout>

复制代码 代码如下:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout

xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="horizontal"

android:layout_height="wrap_content"

android:layout_width="fill_parent"

android:paddingTop="2dip"

android:paddingBottom="2dip"

android:background="@color/list_item_background">

<ImageView

android:id="@+id/photo"

android:layout_height="wrap_content"

android:layout_width="wrap_content"

android:layout_marginLeft="5dip"

android:layout_gravity="center_vertical"

android:layout_weight="1"

android:src="@drawable/default_avatar"

/>

<LinearLayout

android:orientation="vertical"

android:layout_height="wrap_content"

android:layout_width="wrap_content"

android:layout_gravity="center_vertical"

android:layout_marginLeft="5dip"

android:layout_weight="100">

<TextView android:id="@+id/text1"

android:typeface="serif"

android:singleLine="true"

/>

<LinearLayout

android:orientation="horizontal"

android:layout_height="wrap_content"

android:layout_width="wrap_content"

android:layout_marginTop="3dip">

<TextView android:id="@+id/text2"

android:typeface="serif"

android:singleLine="true"

/>

<TextView android:id="@+id/text3"

android:ellipsize="marquee"

android:layout_marginLeft="3dip"

android:marqueeRepeatLimit="marquee_forever"

android:scrollHorizontally="true"

/>

</LinearLayout>

</LinearLayout>

</LinearLayout>

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:

/**

* 显示用户手机上的联系人

*

* @author Mr.Z

* @time 2012-3-21

*

*/

public class ContactsActivity extends Activity {

private Context ctx = ContactsActivity.this;

private Handler handler = new Handler() {

@Override

public void handleMessage(Message msg) {

super.handleMessage(msg);

switch (msg.what) {

case MESSAGE_SUCC_LOAD:

listView.setAdapter(new ContactsAdapter(ctx));

progressDialog.dismiss();

break;

case MESSAGE_SUCC_QUERY:

break;

}

}

};

protected void onCreate(Bundle savedInstanceState) {

requestWindowFeature(Window.FEATURE_NO_TITLE);

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

super.onCreate(savedInstanceState);

this.setContentView(R.layout.contacts);

// 使用listView显示联系人

listView = (ListView) findViewById(R.id.contact_list);

loadAndSaveContacts();

// 绑定listView item的单击事件

listView.setOnItemClickListener(new OnItemClickListener() {

@SuppressWarnings("unchecked")

public void onItemClick(AdapterView<?> adapterView, View view, int position, long _id) {

HashMap<String, String> map = (HashMap<String, String>) adapterView.getItemAtPosition(position);

String phone = map.get("phone");

// 对手机号码进行预处理(去掉号码前的+86、首尾空格、“-”号等)

// 如果当前号码并不是手机号码

if (!SaleUtil.isValidPhoneNumber(phone))

SaleUtil.createDialog(ctx, R.string.dialog_title_tip, getString(R.string.alert_contacts_error_phone));

else {

Intent intent = new Intent();

intent.putExtra("phone", phone);

setResult(RESULT_OK, intent);

// 关闭当前窗口

finish();

}

}

});

contactsSearchView = (EditText) findViewById(R.id.search_view);

contactsSearchView.addTextChangedListener(new TextWatcher() {

public void afterTextChanged(Editable s) {

}

/**

public final class ViewHolder {

}

}

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>> list = new ArrayList<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','%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;
