如何擷取android系統中的連絡人和電話號碼

標籤：

android系統的連絡人資料庫是非常的複雜，並不是一個簡單的表就能搞定的。

要簡單的查詢使用者名稱和電話號碼,首先要查詢到姓名，然後再進局姓名去查詢電話號碼，一個姓名可能對應多個電話號碼：

    // These are the Contacts rows that we will retrieve.    static final String[] CONTACTS_SUMMARY_PROJECTION = new String[]{            ContactsContract.Contacts._ID,            ContactsContract.Contacts.DISPLAY_NAME,            ContactsContract.Contacts.CONTACT_STATUS,            ContactsContract.Contacts.CONTACT_PRESENCE,            ContactsContract.Contacts.PHOTO_ID,            ContactsContract.Contacts.LOOKUP_KEY,} Uri baseUri = ContactsContract.Contacts.CONTENT_URI;        // Now create and return a CursorLoader that will take care of        // creating a Cursor for the data being displayed.        String select = "((" + ContactsContract.Contacts.DISPLAY_NAME + " NOTNULL) AND ("                + ContactsContract.Contacts.HAS_PHONE_NUMBER + "=1) AND ("                + ContactsContract.Contacts.DISPLAY_NAME + " != ‘‘ ))";        return new CursorLoader(ContactActivity.this.getApplicationContext(), baseUri,                CONTACTS_SUMMARY_PROJECTION, select, null,                ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC");List<Map<String, String>> list = new ArrayList<>();        while (data.moveToNext()) {            Map<String, String> map = new HashMap();            String name = data.getString(data.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));            String ContactId = data.getString(data.getColumnIndex(ContactsContract.Contacts._ID));            Cursor phone = getContentResolver().query(                    ContactsContract.CommonDataKinds.Phone.CONTENT_URI,                    null,                    ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + ContactId,                    null,                    null);            while (phone.moveToNext()) {                String Number = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));                if (Number != null) {                    map.put(name, Number);                }            }            list.add(map);        }
