如果使用了
import android.provider.Contacts;import android.provider.Contacts.People;
就要特別注意一下，
因為在android 2.0 SDK當中不建議使用，
請改用
import android.provider.ContactsContract;import android.provider.ContactsContract.PhoneLookup;
要取得聯絡人的姓名sample code如下:
final Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);while(people.moveToNext()){int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME);String contact = people.getString(nameFieldColumnIndex);}people.close();
奇怪的事，如果要取得聯絡人的電話
如果用
int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.NUMBER);String phone = people.getString(nameFieldColumnIndex); //nameFieldColumnIndex return回來的值總是 ─1，
上網google了一下，找到瞭解法，
1. 首先找到目標聯絡人的 _ID，例如要找第一個聯絡人的_ID
Cursor target = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);target.moveToFirst();String contactId = cursor.getString(target.getColumnIndex(ContactsContract.Contacts._ID));
2. 接著透過_ID，來找電話號碼，電話號碼可能不只有一個，所以先判斷有無電話號碼
String IsPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
3. 如果有電話，接著再去query電話號碼
if( (Integer.parseInt(IsPhone) > 0) ){Cursor phoneNumber = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null); while (phones.moveToNext()){String strPhoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));}}
** 如果要查詢e-mail，程式如下
Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null,ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,null, null);while (emails.moveToNext()){ String emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));}
另外
Java代码
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null); while (cursor.moveToNext()) { String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)); if (Boolean.parseBoolean(hasPhone)) { Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null); while (phones.moveToNext()) { String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); } phones.close(); } Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null,ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,null, null); while (emails.moveToNext()) { String emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.CommonDataColumns.DATA)); } emails.close(); } cursor.close();
