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)
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);
}
});
@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：
代码如下:
public class ContactsActivity extends Activity {
private Context ctx = ContactsActivity.this;
private TextView topTitleTextView;
private ListView listView = null;
List<HashMap<String, String>> contactsList = null;
private EditText contactsSearchView;
private ProgressDialog progressDialog = null;
// 数据加载完成的消息
private final int MESSAGE_SUCC_LOAD = 0;
// 数据查询完成的消息
private final int MESSAGE_SUCC_QUERY = 1;
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:
listView.setAdapter(new ContactsAdapter(ctx));
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）
phone = phone.replaceAll("^(\\+86)", "");
phone = phone.replaceAll("^(86)", "");
phone = phone.replaceAll("-", "");
phone = phone.trim();
// 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 void beforeTextChanged(CharSequence s, int start, int count, int after) {
}

queryContacts(s.toString());
}
});
}
private void loadAndSaveContacts() {
progressDialog = ProgressDialog.show(ctx, null, "正在加载联系人数据...");
new Thread() {
@Override
public void run() { // 获取联系人数据

// 临时存储联系人数据

// 查询联系人
Cursor contactsCursor = ctx.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, PhoneLookup.DISPLAY_NAME + " COLLATE LOCALIZED ASC");
// 姓名的索引
int nameIndex = 0;
// 联系人姓名
String name = null;
// 联系人头像ID
String photoId = null;
// 联系人的ID索引值
String contactsId = null;
// 查询联系人的电话号码
Cursor phoneCursor = null;
while (contactsCursor.moveToNext()) {
nameIndex = contactsCursor.getColumnIndex(PhoneLookup.DISPLAY_NAME);
name = contactsCursor.getString(nameIndex);
photoId = contactsCursor.getString(contactsCursor.getColumnIndex(PhoneLookup.PHOTO_ID));

// 添加电话号码
phoneMap.put("phone", phoneCursor.getString(phoneCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
// 添加号码类型（住宅电话、手机号码、单位电话等）
phoneMap.put("type", getString(ContactsContract.CommonDataKinds.Phone.getTypeLabelResource(phoneCursor.getInt(phoneCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE)))));

}

return list;
}
public static Bitmap getPhoto(Context context, String photoId) {

}
public View getView(int position, View convertView, ViewGroup parent) {

return convertView;
}
public final class ViewHolder {
private TextView text1;
private TextView text2;
private TextView text3;
}
}
}
查询方法语句：
代码如下:
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;
}
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：
代码如下:
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();
}
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;
代码如下:
<!-- 访问联系人的权限 -->
<uses-permission android:name="android.permission.READ_CONTACTS" />
