Android提取所有联系人列表（姓名，电子邮件，电话）大约需要700分钟才能完成大约700个联系人

使用59个联系人的以下代码，我在模拟器上获得了以下结果：

      D  ╔══════ query execution stats ═══════
      D  ║    got 59 contacts
      D  ║    query took 0.012 s (12 ms)
      D  ╚════════════════════════════════════

好的，那是最好的时间，但是平均时间是25-35毫秒（对于59个联系人），在一些onClick回调中添加以下代码，然后运行几次以获取平均时间，在您的情况下，您应该获得30 * 700/59 = 〜300-400毫秒，而不是3秒，更不用说1分钟了；）

它使用在API级别18中添加的Uri设置为Contactables.CONTENT_URI，但是在为18个之前的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 idIdx = cursor.getColumnIndex(ContactsContract.Data.CONTACT_ID);
final int nameIdx = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
final int dataIdx = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Contactables.DATA);

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 {
        // mimeType == ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE
        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));
}
final String cOn = "<b><font color='#ff9900'>";
final String cOff = "</font></b>";
Spanned l1 = Html.fromHtml("got " + cOn + array.size() + cOff + " contacts<br/>");
Spanned l2 = Html.fromHtml("query took " + cOn + ms / 1000f + cOff + " s (" + cOn + ms + cOff + " ms)");

Log.d(TAG, "\n\n╔══════ query execution stats ═══════" );
Log.d(TAG, "║    " + l1);
Log.d(TAG, "║    " + l2);
Log.d(TAG, "╚════════════════════════════════════" );
SpannableStringBuilder msg = new SpannableStringBuilder().append(l1).append(l2);

LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
TextView tv = new TextView(this);
tv.setTextSize(20);
tv.setBackgroundColor(0xff000033);
tv.setPadding(24, 8, 24, 24);
tv.setText(msg);
ll.addView(tv);

助手AddressBookContact类：

class AddressBookContact {
    private long id;
    private Resources res;
    private String name;
    private LongSparseArray<String> emails;
    private LongSparseArray<String> phones;

    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, ""))

                }
            }
        }
        return builder.toString();
    }

    public void addEmail(int type, String address) {
