从Android的联系人数据库中获取联系ID没有如预期 [英] Getting Contact ID from Android Contacts database is not working as intended

问题描述

我有以下的code。

  INT phoneContactID =新的随机（）nextInt（）;

    光标contactLookupCursor = context.getContentResolver（）查询（Uri.withAppendedPath（PhoneLookup.CONTENT_FILTER_URI，Uri.en code（contactNumber）），新的String [] {PhoneLookup.DISPLAY_NAME，PhoneLookup._ID}，NULL，NULL，NULL ）;

    尝试
    {
        contactLookupCursor.moveToFirst（）;
        而（contactLookupCursor.moveToNext（））
        {
            phoneContactID = contactLookupCursor.getInt（co​​ntactLookupCursor.getColumnIndexOrThrow（PhoneLookup._ID））;
         }
    }
    最后
    {
        contactLookupCursor.close（）;
    }
 

在上面的code的问题是，即使我给一个现有号码在仿真器的接触，其不返回任何结果。我测试了一个小时，回来了，它是工作的罚款，而现在，当我再次测试它，它不返回任何东西。我不知道什么是错的code。我所要做的就是获得一个ID匹配多号单。例如说，有一个名为A联系人姓名和A有两个数字。实际上对于A的接触式ID应该是1不管我指的是哪一些。我的假设是正确的？

更新：我做了一些更多的测试。比方说，如果一个号码存储，而不该国code像222-222-2222联系人数据库。使用下面的code回报接触式ID搜查只有当我通过2222222222或222-222-2222。如果相同的号码存储像12222222222一个有效的接触式ID只收到如果我搜索号码是12222222222.

 的String []投影=新的String [] {ContactsContract.CommonDataKinds.Phone._ID，ContactsContract.CommonDataKinds.Phone.CONTACT_ID};
    乌里contactUri = Uri.withAppendedPath（ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI，Uri.en code（contactNumber））;
    光标C = context.getContentResolver（）查询（contactUri，投影，NULL，NULL，NULL）;
    如果（c.moveToFirst（））{
        phoneContactID = c.getInt（c.getColumnIndex（ContactsContract.CommonDataKinds.Phone.CONTACT_ID））;
    }
 

我不知道如果我在这里做得不对。任何帮助将是AP preciated。

解决方案

 公共静态INT getContactIDFromNumber（字符串contactNumber，上下文语境）
{
    contactNumber = Uri.en code（contactNumber）;
    。INT phoneContactID =新的随机（）nextInt（）;
    光标contactLookupCursor = context.getContentResolver().query(Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,Uri.contactNumber),new的String [] {PhoneLookup.DISPLAY_NAME，PhoneLookup._ID}，NULL，NULL，NULL）;
        而（contactLookupCursor.moveToNext（））{
            phoneContactID = contactLookupCursor.getInt（co​​ntactLookupCursor.getColumnIndexOrThrow（PhoneLookup._ID））;
            }
        contactLookupCursor.close（）;

    返回phoneContactID;
}
 

在code是现在的工作。

I have the following code.

        int phoneContactID = new Random().nextInt();

    Cursor contactLookupCursor =  context.getContentResolver().query( Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,Uri.encode(contactNumber)), new String[] {PhoneLookup.DISPLAY_NAME, PhoneLookup._ID},null,null,null);     

    try 
    {
        contactLookupCursor.moveToFirst();
        while(contactLookupCursor.moveToNext())
        {
            phoneContactID = contactLookupCursor.getInt(contactLookupCursor.getColumnIndexOrThrow(PhoneLookup._ID));
         }
    } 
    finally 
    {
        contactLookupCursor.close();
    }       

The problem in the above code is that even if I give a existing number in emulator contacts, its not returning any results. I was testing it an hour back and it was working fine, and now when I tested it again, its not returning anything. I am not sure if anything is wrong with the code. What I am trying to do is get a ID that matches a single with multiple numbers. For instance say there is a contact name called "A" and A has two numbers. Essentially the contact ID for A should be 1 regardless of which number I refer to. Is my assumption correct ?

UPDATE : I did some more tests. Let's say if a number is stored without the country code in the contacts database like 222-222-2222. A search using the below code returns contact id only when I pass 2222222222 or 222-222-2222. And if the same number is stored like 12222222222 a valid contact id is received only if I search number is 12222222222.

        String[] projection = new String[] {ContactsContract.CommonDataKinds.Phone._ID,ContactsContract.CommonDataKinds.Phone.CONTACT_ID};
    Uri contactUri = Uri.withAppendedPath(ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI, Uri.encode(contactNumber));
    Cursor c = context.getContentResolver().query(contactUri, projection, null, null, null);
    if (c.moveToFirst()) {
        phoneContactID = c.getInt(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
    }

I am not sure if I am doing something wrong here. Any help would be appreciated.

解决方案

public static int getContactIDFromNumber(String contactNumber,Context context)
{
    contactNumber = Uri.encode(contactNumber);
    int phoneContactID = new Random().nextInt();
    Cursor contactLookupCursor = context.getContentResolver().query(Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,Uri.contactNumber),new String[] {PhoneLookup.DISPLAY_NAME, PhoneLookup._ID}, null, null, null);
        while(contactLookupCursor.moveToNext()){
            phoneContactID = contactLookupCursor.getInt(contactLookupCursor.getColumnIndexOrThrow(PhoneLookup._ID));
            }
        contactLookupCursor.close();

    return phoneContactID;
}

The code that is working now.
