我正在尝试取消与姓名，手机号码，电子邮件地址和生日的联系，但是操作花费了太多时间（顺便提一下设备有2000个联系人）。即使UI被挂起，如果我在自定义进度对话框中显示动画，它也不是动画。
（快速联系人提取或动画至少应该有效）。
（甚至，我已经使用asynctask进行联系提取和动画，但我得到了相同的结果）。
这是我的代码
ContactListClass.phoneList.clear();
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cur.getCount() > 0) {
int progress = 0;
// customIndeterminantDialog.setMax(cur.getCount());
int i = 0;
while (cur.moveToNext()) {
ContactObject contactObject = new ContactObject();
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
// if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
// Query phone here. Covered next
JSONObject jsonObject = new JSONObject();
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id}, null);
String phoneNo = "";
String emailId = "";
while (pCur.moveToNext()) {
// Do something with phones
phoneNo = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
phoneNo = phoneNo.replaceAll("\\W+", "");
}
// Cursor emailCur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", new String[]{id}, null);
//
// if (emailCur != null || emailCur.getCount() > 0) {
//
// while (emailCur.moveToNext()) {
// String emailContact = emailCur.getString(emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
// if (emailContact != null) {
// emailId = emailContact;
//
// } else {
// emailId = "";
// }
// }
// emailCur.close();
// }
contactObject.setName(name);
contactObject.setphone(phoneNo);
contactObject.setEmail(emailId);
contactObjectsList.add(contactObject);
//customIndeterminantDialog.setProgress(++progress);
pCur.close();
// }
i++;
}
customIndeterminantDialog.dismiss();
} else {
customIndeterminantDialog.dismiss();
}
