android通訊錄根據手機號碼查詢姓名
阿新 • • 發佈：2018-12-28
最近有個關於通訊錄開發的需求，需求很簡單：根據手機號碼查詢姓名。之前有獲取通訊錄列表的程式碼如下：
/** * 獲取本機手機聯絡人列表 * * @author yinbiao * @date 2016-4-5 上午11:03:48 * @param context * @return */ public synchronized static List<MocamContact> getLocalPhoneContacts(Context context) { String[] projection = { Phone.DISPLAY_NAME, Phone.NUMBER }; List<MocamContact> list = new ArrayList<MocamContact>(); ContentResolver resolver = context.getContentResolver(); // 獲取手機聯絡人 Cursor cursor = resolver.query(Phone.CONTENT_URI, projection, null, null, null); if (cursor != null) { while (cursor.moveToNext()) { // 得到手機號碼 String phoneNumber = cursor.getString(cursor.getColumnIndex(Phone.NUMBER)); // 如果不是正確的手機號碼 跳過當前迴圈 if (!isMobileNomber(phoneNumber)) { continue; } // 得到聯絡人名稱 String name = cursor.getString(cursor.getColumnIndex(Phone.DISPLAY_NAME)); MocamContact contact = new MocamContact(phoneNumber, name); list.add(contact); } cursor.close(); } return list; }
/** * 判斷是否是正確的手機號碼 * * @author yinbiao * @date 2016-4-6 下午3:17:17 * @param mobileNumber * @return */ public static boolean isMobileNomber(String mobileNumber) { if (TextUtils.isEmpty(mobileNumber)) { return false; } Pattern p = Pattern.compile("^((13[0-9])|(15[^4,\\D])|(18[0,5-9]))\\d{8}$"); Matcher m = p.matcher(mobileNumber); return m.matches(); }
實現該需求，我只需要拿到手機號碼，然後去 Phone.CONTENT_URI表查詢姓名欄位即可，so 程式碼如下：
是不是比較簡單？但是 坑 出現了，真機除錯中，根據手機號碼怎麼都查詢不到姓名，反覆檢查程式碼沒有發現問題所在，百思不得其解。/** * 根據手機號碼查詢聯絡人姓名 * * @author yinbiao * @date 2016-4-6 上午9:29:42 * @param context * @param phoneNum * @return */ public synchronized static String getDisplayNameByPhone(Context context, String phoneNum) { String displayName = null; ContentResolver resolver = context.getContentResolver(); Cursor cursor = resolver.query(Phone.CONTENT_URI, projection, Phone.NUMBER + "=?", new String[]{phoneNum}, null); if (cursor != null) { while (cursor.moveToNext()) { displayName = cursor.getString(cursor.getColumnIndex(Phone.DISPLAY_NAME)); if (!TextUtils.isEmpty(displayName)) { break; } } } return displayName; }
然後反其道行之，寫了一個根據姓名查詢手機號碼的demo，程式碼如下：
public synchronized static String getPhoneByName(Context context, String name) {
String displayName = null;
ContentResolver resolver = context.getContentResolver();
Cursor cursor = resolver.query(Phone.CONTENT_URI, projection, Phone.DISPLAY_NAME + "=?",
new String[]{name}, null);
if (cursor != null) {
while (cursor.moveToNext()) {
displayName = cursor.getString(cursor.getColumnIndex(Phone.NUMBER));
if (!TextUtils.isEmpty(displayName)) {
break;
}
}
}
return displayName;
}
仔細一看，資料庫中存的手機號碼中間居然有空格，終於知道了問題的原因，這下好改了，只需要查詢是，給手機號碼中間特定的位置插入空格就OK，查資料發現有些系統沒有空格，有些系統中間加的是橫線 “-”；所以將程式碼做如下改動：
/**
* 根據手機號碼查詢聯絡人姓名
*
* @author yinbiao
* @date 2016-4-6 上午9:29:42
* @param context
* @param phoneNum(傳入純數字手機號碼)
* @return
*/
public synchronized static String getDisplayNameByPhone1(Context context, String phoneNum) {
String displayName = null;
String phone1 = new StringBuffer(phoneNum.subSequence(0, 3)).append(" ").append(phoneNum.substring(3, 7))
.append(" ").append(phoneNum.substring(7, 11)).toString();
String phone2 = new StringBuffer(phoneNum.subSequence(0, 3)).append("-").append(phoneNum.substring(3, 7))
.append("-").append(phoneNum.substring(7, 11)).toString();
ContentResolver resolver = context.getContentResolver();
Cursor cursor = resolver.query(Phone.CONTENT_URI, projection, Phone.NUMBER + " in(?,?,?)", new String[] {
phoneNum, phone1, phone2 }, null);
if (cursor != null) {
while (cursor.moveToNext()) {
displayName = cursor.getString(cursor.getColumnIndex(Phone.DISPLAY_NAME));
if (!TextUtils.isEmpty(displayName)) {
break;
}
cursor.close();
}
}
return displayName;
}
