目前,我使用此代碼,以獲得聯繫人姓名和電話號碼:優化ContentProvider的查詢檢索聯繫人姓名和電話
ContentResolver contentResolver = getContentResolver();
Cursor people = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
int nameIndex = people.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
int idIndex = people.getColumnIndex(ContactsContract.Contacts._ID);
int hasPhoneNumberIndex = people.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER);
String name, id;
int hasPhoneNumber;
while(people.moveToNext()){
name = people.getString(nameIndex);
id = people.getString(idIndex);
hasPhoneNumber = people.getInt(hasPhoneNumberIndex);
if(hasPhoneNumber > 0){
Cursor phones = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+id, null, null);
phones.moveToFirst();
int phoneIndex = phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
String phone = phones.getString(phoneIndex);
HashMap<String, String> namePhoneType = new HashMap<String, String>();
namePhoneType.put("Name", name);
namePhoneType.put("Phone", phone);
m_peopleList.add(namePhoneType);
phones.close();
}
}
但這是極其緩慢。
有沒有辦法在只有一個查詢檢索的姓名和電話?
