Question

我尝试从具有API 23权限的通讯录中获取电话号码，但电话号码始终返回空字符串。已经验证了获取联系人的权限，并且联系人似乎有效，但是对于任何联系人来说，电话字段似乎都不存在。＆＃34; cr.query ...＆＃34;似乎没有带回任何东西因为＆＃34;而（phones.moveToNext）＆＃34;从未表现出真实。我使用以下代码来获取电话号码。任何想法为什么电话号码不显示任何联系？

def scrub(x):
    ret = copy.deepcopy(x)
    if isinstance(x, dict):
        for k, v in ret.items():
            ret[k] = scrub(v)
    if isinstance(x, (list, tuple)):
        for k, v in enumerate(ret):
            ret[k] = scrub(v)
    if x is None:
        ret = ''
    return ret

更新：不知道为什么这种方法不起作用，但找到了另一种方法可行。

                ContentResolver cr = getContentResolver();
                cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
                if (cursor.moveToFirst()) {
                    String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));

                    Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                            ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId, null, null);
                    while (phones.moveToNext()) {
                        String number = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                        int type = phones.getInt(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));
                        switch (type) {
                            case ContactsContract.CommonDataKinds.Phone.TYPE_HOME:
                                // do something with the Home number here...
                                break;
                            case ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE:
                                PhoneNumber = number;
                                break;
                            case ContactsContract.CommonDataKinds.Phone.TYPE_WORK:
                                // do something with the Work number here...
                                break;
                        }
                    }
                    phones.close();
                }
                cursor.close();

此方法正常。

您可以尝试使用以下方法使用 ContactContract 获取电话号码详细信息：

private void retrieveContactNumber() {

    String contactNumber = null;

    // getting contacts ID
    Cursor cursorID = getContentResolver().query(uriContact,
            new String[]{ContactsContract.Contacts._ID},
            null, null, null);

    if (cursorID.moveToFirst()) {

        contactID = cursorID.getString(cursorID.getColumnIndex(ContactsContract.Contacts._ID));
    }

    cursorID.close();

    Log.d(TAG, "Contact ID: " + contactID);

    // Using the contact ID now we will get contact phone number
    Cursor cursorPhone = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
            new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},

            ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ? AND " +
                    ContactsContract.CommonDataKinds.Phone.TYPE + " = " +
                    ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE,

            new String[]{contactID},
            null);

    if (cursorPhone.moveToFirst()) {
        contactNumber = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
    }

    cursorPhone.close();

    Log.d(TAG, "Contact Phone Number: " + contactNumber);
}

对于所有联系人，Phone.NUMBER返回空
