添加自定义字段，一个电话号码 [英] Add a custom field to a phone number

问题描述

我建立一个应用程序需要自定义联系人字段（'白名单'，如果你想知道）对每一个电话号码。

Am building an app that requires a custom contact field ('whitelist', if you were wondering) for every phone number.

不过，我只找到保存自定义的数据为每个联系人，与 Data.RAW_CONTACT_ID 的一种方式，但不是每个电话号码。我试图用 Phone._id ，但我得到了一个 java.nullpointerexception 错误。

However, I only found a way of saving custom data for each contact, with Data.RAW_CONTACT_ID, but not for each phone number. I tried using Phone._id, but I got a java.nullpointerexception error.

这是在code我现在有：

This is the code I have now:

try{ //phoneId = get Phone._ID from cursor
  ContentValues values = new ContentValues();                           
  values.put(Data.DATA1, "yes");
  int state = getContentResolver().update(Phone.CONTENT_URI, values, Phone._ID + " = " 
              + phoneId + " AND " +  Data.MIMETYPE + "='" + MIMETYPE_WHITELIST_CONTACT+"'", null);
         if (state == 0) {
             values.put(Phone._ID, phoneId);
             values.put(Data.DATA1, "yes");
             values.put(Data.MIMETYPE, MIMETYPE_WHITELIST_CONTACT);
                            getContentResolver().insert(Data.CONTENT_URI, values);
        }  
}catch (Exception e) {
    Toast.makeText(ChooseContactsActivity.this,  e.toString(), Toast.LENGTH_LONG).show();
}

没有任何人有任何想法需要改变什么，因此可以保存自定义字段的电话号码，而不是接触？

Does anyone have any idea what needs to be changed so it can save a custom field for the phone number, not the contact?

推荐答案

好吧，我理解了它。也许有更好的解决方案，但这个工作对我来说：

All right, I figured it out. Maybe there is a better solution, but this works for me:

    values.put(Data.RAW_CONTACT_ID, contactId);
    values.put(Data.DATA1, phoneId);
    values.put(Data.DATA2, "1");
    values.put(Data.DATA5, phoneNum);
    values.put(Data.MIMETYPE, MIMETYPE_WHITELIST_CONTACT);
getContentResolver().insert(Data.CONTENT_URI, values);

当我询问，我只需要添加phoneId得到的结果，我需要：

When I query, I just have to add the phoneId to get the result I need:

getContentResolver().query(Data.CONTENT_URI, {Data.DATA1, Data.DATA2},
 Data.RAW_CONTACT_ID + " = " + contactId +  " AND "  + 
    Data.DATA1 + " = " + phoneId + " AND "  +
            Data.MIMETYPE + "='" + MIMETYPE_WHITELIST_CONTACT+"'", null, null);
