《Android開發卷——手機連絡人T9搜尋》

標籤：擷取手機連絡人   contract   t9搜尋   android   撥號演算法   

    

自己研究了好幾天連絡人的T9搜尋演算法, 先分享出來給大家看看. 歡迎指教.如果有大神有更好的T9搜尋演算法, 那更好啊,大家一起研究研究,謝謝.

第一部分是比較簡單的擷取手機連絡人.

擷取連絡人前提要有許可權.

<uses-permission android:name="android.permission.READ_CONTACTS" />

因為手機的連絡人都儲存在資料庫裡面,所以我們只要把資料庫裡的資訊查詢出來即可.

private static final String[] PHONES_PROJECTION = new String[] {
Phone.DISPLAY_NAME, Phone.NUMBER, Photo.SORT_KEY_ALTERNATIVE};

ContentResolver resolver = getBaseContext().getContentResolver();
Cursor phoneCursor = resolver.query(Phone.CONTENT_URI,
PHONES_PROJECTION, null, null, null);

這裡我只是簡單的說一下而已,後面的遍曆phoneCursor 就能把連絡人查詢出來.(我項目裡是開一條線程擷取連絡人的,以防太多連絡人導致頁面空白或者卡頓)

第二部分是T9搜尋部分

思路是: a只要連絡人的號碼有包含我輸入的數字就add到list進去,

b連絡人的姓名拼音有包含我輸入的拼音就add到list進去,

c連絡人的姓名縮寫拼音有包含我輸入的拼音就add到list進去

舉個例子--連絡人姓名:測試,號碼:1234567890

情況一:我輸入1234567890就能把測試顯示出來

情況二:我輸入23744(ceshi),因為這個"測試"的拼音,所以也能把測試顯示出來

情況三:我輸入(27)cs,這是"測試"的拼音縮寫,所以也能把測試顯示出來

當然我輸入23(ce)或者744(shi)什麼的,都可以把測試顯示出來.

以上是我的思路,下面附上一段代碼
