在联系人选取器中获取不正确的联系人号码 - Android

【中文标题】在联系人选取器中获取不正确的联系人号码 - Android【英文标题】:Incorrect Contact Number Fetching in Contact Picker - Android 【发布时间】:2018-01-09 07:59:51 【问题描述】:我正在使用联系人选择器将号码发送到 editText。根据用户保存特定号码的方式,保存的联系人号码可以分为三种类型。
-
+911234567899(前缀为+91)[印度国家代码]。
01234567899(以 0 为前缀)[用于拨打手机号码的常用 STD 码]。
1234567899(无前缀)。
我需要删除前缀(如果有)并在我的 editText 中获取不带空格的实际 10 位数字(一些设备在数字之间放置空格以提高可读性)。
现在我面临的问题是,这仅适用于您第一次选择每种类型的联系人时,例如,它适用于您第一次选择前缀号码和非前缀号码。下次你尝试它时,它不会像我需要的那样工作。但是如果我们重新启动应用程序,它会再次完美运行。
这是代码:

【问题讨论】:
两个通用 cmets - 您正在使用正则表达式来删除所有空格 (contactNumber.replaceAll("\\s","")
) - 为什么不这样做来删除前导 0(类似于:contactNumber.replaceAll("^0", "")
)和 + 91?这将大大简化 retrieveContactNumber
方法中的代码。再想一想 - 您似乎很乐意将其仅限于印度电话号码 (+91),但不要忘记其他国家/地区有不同的代码和不同的格式。
【参考方案1】:
我同意@DaveyDaveDave 静态字段不是要走的路,但如果你坚持这里是你的相同代码,有很多修复和简化的代码。 请注意,仅 API 16 及更高版本支持 NORMALIZED_NUMBER。
class ClassGetPhoneNumber
...
public static void retrieveContactNumber(Context context, Uri uriContact)
sResponse = null;
sContactNumber = null;
sContactNumberFinal = null;
// get contactID from contactUri
long contactID = ContentUris.parseId(contactUri);
// Using the contact ID now we will get contact phone number
// Don't add selection by Phone.TYPE as we might miss a lot of phones.
// We ask for the normalized number, this will only work for API 16 and above
Cursor cursorPhone = context.getContentResolver().query(CommonDataKinds.Phone.CONTENT_URI,
new String[]CommonDataKinds.Phone.NORMALIZED_NUMBER, CommonDataKinds.Phone.NUMBER,
CommonDataKinds.Phone.CONTACT_ID + " = " + contactID,null,null);
contactNumber = null;
if (cursorPhone != null && cursorPhone.moveToFirst())
contactNumber = cursorPhone.getString(0); // this number will always be of e164 format: "+<country><local number>"
Log.d(TAG, "normalized number: " + contactNumber + ", original number: " + cursorPhone.getString(1) + ", contact-id: " + contactID);
else
// you need to quit here, otherwise you'll be using an old value of contactNumber in the rest of the code.
if (cursorPhone != null)
cursorPhone.close();
return;
cursorPhone.close();
if (!TextUtils.isEmpty(contactNumber))
sContactNumber = contactNumber;
sContactNumberFinal = sContactNumber.substring(3);
sResponse = sContactNumberFinal;
sStatus = "OK";
else
// no phone was found
sStatus = "NOT FOUND";
【讨论】:
感谢@marmor 提出并解决我的问题。这个工作正常,我添加了 sn-p 以删除 +91 和 0,而没有使用冗长的 if_statement 来达到我的目的。 很好,如果您确实需要支持 API 15 及更低版本,或者有时从 NORMALIZED_NUMBER 中获取 null,请查看 Google 的 libphonenumber 实用程序以处理和格式化电话号码:github.com/googlei18n/libphonenumber【参考方案2】:很难遵循您的代码,因为发生了很多事情,但我认为根本原因是您的 ClassGetPhoneNumber
类中的所有内容都是静态的,因此该类中的字段是在第一遍设置的,并且它们的值在您下次调用 retrieveContactNumber
方法时保持不变。
从观察来看,我怀疑它并不像第一次工作并且随后不工作那么简单,而是您通常会得到“奇怪”的行为,具体取决于输入。
最简单的解决方案是从ClassGetPhoneNumber
类中删除所有static
关键字,并将调用更改为:
ClassGetPhoneNumber.retrieveContactNumber(getApplicationContext(),uriContact);
到:
new ClassGetPhoneNumber().retrieveContactNumber(getApplicationContext(),uriContact);
我认为这将解决您面临的直接问题。
【讨论】:
【参考方案3】:我想通了。
问题是: 我用来确定用户如何保存的变量的值 特定数字(With91、With0、TenDigit)在开始时未初始化为零 retrieveContactNumber() 方法。 在函数开始时将它们初始化为零清除了之前的 值并使其按预期工作。
感谢大家的时间和支持。 ——保罗·瓦尔盖斯
【讨论】:
嘿,保罗,您的代码中似乎还有其他问题:(1)您不能假设手机的类型为“MOBILE”,它可能设置为其他标签(MAIN、CUSTOM , PRIVATE, WORK),您应该从选择中删除它。 (2) 您可以通过long contactId = ContentUris.parseId(contactUri);
(3) 代替正则表达式和解析电话号码,使用 CommonDataKinds.Phone.NORMALIZED_NUMBER 始终获得相同的类型
你能用我的代码解释一下吗?这会很有帮助。
是的,我添加了一个固定版本作为新答案,请注意我所有的 cmets 内联以上是关于在联系人选取器中获取不正确的联系人号码 - Android的主要内容,如果未能解决你的问题,请参考以下文章
