我需要获取所有电话联系人及其电子邮件地址和照片 uri：
这就是正在做的事情：
private void getContacts() {
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(Contacts.CONTENT_URI, null, null, null, Contacts.DISPLAY_NAME);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
// if
// (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)))
// > 0) {
Contact contact = new Contact();
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
Uri uri = getContactPhotoUri(Long.parseLong(id));
// set photoUri
contact.setContactPhotoUri(uri);
// set name
contact.setContactName(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)));
// get the phone number
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id }, null);
while (pCur.moveToNext()) {
// set phone munber
contact.setContactNumber(pCur.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
contacts.add(contact);
}
pCur.close();
// get email and type
Cursor emailCur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", new String[] { id }, null);
while (emailCur.moveToNext()) {
// This would allow you get several email addresses
// if the email addresses were stored in an array
// set email
contact.setContactEmail(emailCur.getString(emailCur
.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)));
contacts.add(contact);
}
emailCur.close();
}
}
cur.close();
contactAdapter = new ContactAdapter(this, R.id.contactList, contacts);
// }
}
public Uri getContactPhotoUri(long contactId) {
Uri photoUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, contactId);
photoUri = Uri.withAppendedPath(photoUri, Contacts.Photo.CONTENT_DIRECTORY);
return photoUri;
}
我的问题是获取所有联系人，包括 gmail 联系人，我不希望包含 gmail 联系人。而且耗时也很慢。我如何优化这个，我知道它需要时间，因为我使用了很多光标.. 但不知道如何制作一个可以给我姓名电子邮件号码照片 uri 的单个光标......谢谢！
更新的决赛：
private void getContacts() {
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(Data.CONTENT_URI, new String[] { Data.CONTACT_ID, Data.MIMETYPE, Email.ADDRESS,
Contacts.DISPLAY_NAME, Phone.NUMBER }, null, null, Contacts.DISPLAY_NAME);
Contact contact;
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(Data.CONTACT_ID));
String mimeType = cur.getString(cur.getColumnIndex(Data.MIMETYPE));
if (allContacts.containsKey(id)) {
// update contact
contact = allContacts.get(id);
} else {
contact = new Contact();
allContacts.put(id, contact);
// set photoUri
contact.setContactPhotoUri(getContactPhotoUri(Long.parseLong(id)));
}
if (mimeType.equals(StructuredName.CONTENT_ITEM_TYPE))
// set name
contact.setContactName(cur.getString(cur.getColumnIndex(Contacts.DISPLAY_NAME)));
if (mimeType.equals(Phone.CONTENT_ITEM_TYPE))
// set phone munber
contact.setContactNumber(cur.getString(cur.getColumnIndex(Phone.NUMBER)));
if (mimeType.equals(Email.CONTENT_ITEM_TYPE))
// set email
contact.setContactEmail(cur.getString(cur.getColumnIndex(Email.ADDRESS)));
}
}
cur.close();
// get contacts from hashmap
contacts.clear();
contacts.addAll(allContacts.values());
// remove null contacts
for (Contact _contact : contacts) {
if (_contact.getContactName() == null && _contact.getContactNumber() == null
&& _contact.getContactEmail() == null) {
contacts.remove(_contact);
break;
}
}
contactAdapter = new ContactAdapter(this, R.id.contactList, contacts);
contactAdapter.notifyDataSetChanged();
}
public Uri getContactPhotoUri(long contactId) {
Uri photoUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, contactId);
photoUri = Uri.withAppendedPath(photoUri, Contacts.Photo.CONTENT_DIRECTORY);
return photoUri;
}
