有没有办法缩短这个时间？ 我正在使用光标运行并获取姓名，电话号码和电子邮件
如果我从查询循环中删除电话号码查询，则会在3秒内结束
任何想法如何改进该查询？
也许我在查询中做错了什么？
（显然我正在做异步但仍然......用户已经很长时间不能等了）
希望有人可以分享他对此的看法
这是我的代码
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
AddressBookEntity adr = new AddressBookEntity();
String id = cur.getString(cur
.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
adr.fullName = name;
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
String email = emailCur
.getString(emailCur
.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
if (!Utils.IsNullOrEmptyString(email)) {
adr.email = email;
}
}
emailCur.close();
if (Integer
.parseInt(cur.getString(cur
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = cr
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?",
new String[] { id }, null);
int phoneIndex = 0;
while (pCur.moveToNext()) {
String number = pCur.getString(pCur
.getColumnIndex(Phone.NUMBER));
String country = Utils.GetCountryFromNumber(
number, app);
number = Utils.GetFullPhoneNumber(number, app);
if (phoneIndex == 0) {
if (!Utils.IsNullOrEmptyString(number)) {
adr.contactAdressBookId = id;
adr.phoneNumber = number;
adr.userInsertedId = app.userCred.userId;
adr.country = country;
myContacts.add(adr);
}
} else {
if (!Utils.IsNullOrEmptyString(number)) {
AddressBookEntity adrMore = new AddressBookEntity();
adrMore.fullName = adrMore.fullName;
adrMore.country = adrMore.country;
adrMore.email = adrMore.email;
adrMore.phoneNumber = number;
adrMore.contactAdressBookId = id;
adrMore.country = country;
myContacts.add(adrMore);

使用以下代码为59个联系人我在模拟器上得到以下结果：
D ╔══════ query execution stats ═══════
D ║ got 59 contacts
D ║ query took 0.012 s (12 ms)
D ╚════════════════════════════════════
它在API级别18中添加了Uri设置为 Contactables.CONTENT_URI ，但在为18个API设备构建时可以使用 ContactsContract.Data.CONTENT_URI
List<AddressBookContact> list = new LinkedList<AddressBookContact>();
LongSparseArray<AddressBookContact> array = new LongSparseArray<AddressBookContact>();
long start = System.currentTimeMillis();
String[] projection = {
ContactsContract.Data.MIMETYPE,
ContactsContract.Data.CONTACT_ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Contactables.DATA,
ContactsContract.CommonDataKinds.Contactables.TYPE,
};
String selection = ContactsContract.Data.MIMETYPE + " in (?, ?)";
String[] selectionArgs = {
ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE,
ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,
};
String sortOrder = ContactsContract.Contacts.SORT_KEY_ALTERNATIVE;
Uri uri = ContactsContract.CommonDataKinds.Contactables.CONTENT_URI;
// we could also use Uri uri = ContactsContract.Data.CONTENT_URI;
// ok, let's work...
Cursor cursor = getContentResolver().query(uri, projection, selection, selectionArgs, sortOrder);
final int mimeTypeIdx = cursor.getColumnIndex(ContactsContract.Data.MIMETYPE);

final int typeIdx = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Contactables.TYPE);
while (cursor.moveToNext()) {
long id = cursor.getLong(idIdx);
AddressBookContact addressBookContact = array.get(id);
if (addressBookContact == null) {
addressBookContact = new AddressBookContact(id, cursor.getString(nameIdx), getResources());
array.put(id, addressBookContact);
list.add(addressBookContact);
}
int type = cursor.getInt(typeIdx);
String data = cursor.getString(dataIdx);
String mimeType = cursor.getString(mimeTypeIdx);
if (mimeType.equals(ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE)) {
// mimeType == ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE
addressBookContact.addEmail(type, data);
} else {

addressBookContact.addPhone(type, data);
}
}
long ms = System.currentTimeMillis() - start;
cursor.close();
// done!!! show the results...
int i = 1;
for (AddressBookContact addressBookContact : list) {
Log.d(TAG, "AddressBookContact #" + i++ + ": " + addressBookContact.toString(true));

AddressBookContact(long id, String name, Resources res) {
this.id = id;
this.name = name;
this.res = res;
}
@Override
public String toString() {
return toString(false);
}
public String toString(boolean rich) {
SpannableStringBuilder builder = new SpannableStringBuilder();
if (rich) {
builder.append("id: ").append(Long.toString(id))
.append(", name: ").append("\u001b[1m").append(name).append("\u001b[0m");
} else {
builder.append(name);
}
if (phones != null) {
builder.append("\n\tphones: ");
for (int i = 0; i < phones.size(); i++) {
int type = (int) phones.keyAt(i);
builder.append(ContactsContract.CommonDataKinds.Phone.getTypeLabel(res, type, ""))
.append(": ")
.append(phones.valueAt(i));
if (i + 1 < phones.size()) {
builder.append(", ");
}
}
}
if (emails != null) {
builder.append("\n\temails: ");
for (int i = 0; i < emails.size(); i++) {
int type = (int) emails.keyAt(i);
builder.append(ContactsContract.CommonDataKinds.Email.getTypeLabel(res, type, ""))
.append(": ")
.append(emails.valueAt(i));
if (i + 1 < emails.size()) {
builder.append(", ");
}
}
}
return builder.toString();
}
public void addEmail(int type, String address) {
if (emails == null) {
emails = new LongSparseArray<String>();
}
emails.put(type, address);
}
public void addPhone(int type, String number) {
if (phones == null) {
phones = new LongSparseArray<String>();
}
phones.put(type, number);
}
}

您可以检索查询中的所有列：
public static HashMap<String, String> createDefaultHashMap() {
HashMap<String, String> c = new HashMap<String, String>();
c.put("x", "y");
c.put("f", "g");
return c;
}
public Foo(String a, String b) {
this(a, b, Foo.createDefaultHashMap());;
}
这使数据处理速度慢得多。如果您定义了一个真正需要检索的列数组，那么速度会快得多。
