android中如何取得使用者手機的常用聯絡人（即收藏夾的聯絡人）
程式碼：
/**
* 獲得收藏夾的聯絡人
*/
private void getKeepedContacts(){
Cursor cur = getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI, null, ContactsContract.Contacts.STARRED + " = 1 " , null, null);
startManagingCursor(cur);
int num = cur.getCount();
System.out.println(num + "");
int count = 0;
while (cur.moveToNext()) {
count ++;
long id = cur.getLong(cur.getColumnIndex("_id"));
Cursor pcur = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "="
+ Long.toString(id), null, null);
// 處理多個號碼的情況
String phoneNumbers = "";
while (pcur.moveToNext()) {
String strPhoneNumber = pcur
.getString(pcur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
phoneNumbers += strPhoneNumber + ":";
}
phoneNumbers += "\n";
pcur.close();
String name = cur.getString(cur.getColumnIndex("display_name"));
contactNameList.add(name);
contactNumList.add(phoneNumbers);
}
cur.close();
}
